Medicare Program; Proposed Changes to the Hospital Outpatient 
Prospective Payment System and Calendar Year 2005 Payment Rates

AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This proposed rule would revise the Medicare hospital 
outpatient prospective payment system to implement applicable statutory 
requirements and changes arising from our continuing experience with 
this system and to implement certain related provisions of the Medicare 
Prescription Drug, Improvement, and Modernization Act of 2003. In 
addition, the proposed rule describes proposed changes to the amounts 
and factors used to determine the payment rates for Medicare hospital 
outpatient services paid under the prospective payment system. These 
changes would be applicable to services furnished on or after January 
1, 2005.

I. Background

A. Legislative and Regulatory Authority for the Outpatient Prospective 
Payment System

    When the Medicare statute was originally enacted, Medicare payment 
for hospital outpatient services was based on hospital-specific costs. 
In an effort to ensure that Medicare and its beneficiaries pay 
appropriately for services and to encourage more efficient delivery of 
care, the Congress mandated replacement of the cost-based payment 
methodology with a prospective payment system (PPS). The Balanced 
Budget Act of 1997 (BBA) (Pub. L. 105-33), enacted on August 5, 1997, 
added section 1833(t) to the Social Security Act (the Act) authorizing 
implementation of a PPS for hospital outpatient services. The Balanced 
Budget Refinement Act of 1999 (BBRA) (Pub. L. 106-113), enacted on 
November 29, 1999, made major changes that affected the hospital 
outpatient PPS (OPPS). The Medicare, Medicaid, and SCHIP Benefits 
Improvement and Protection Act of 2000 (BIPA) (Pub. L. 106-554), 
enacted on December 21, 2000, made further changes in the OPPS. Section 
1833(t) of the Act was also recently amended by the Medicare 
Prescription Drug, Improvement, and Modernization Act of 2003, Pub. L. 
108-173, enacted on December 8, 2003 (these amendments are discussed 
later under section I.E. of this proposed rule). The OPPS was first 
implemented for services furnished on or after August 1, 2000. 
Implementing regulations for the OPPS are located at 42 CFR part 419.
    Under the OPPS, we pay for hospital outpatient services on a rate-
per-service basis that varies according to the ambulatory payment 
classification (APC) group to which the service is assigned. We use 
Healthcare Common Procedure Coding System (HCPCS) codes (which include 
certain Current Procedural Terminology (CPT) codes) and descriptors to 
identify and group the services within each APC. The OPPS includes 
payment for most hospital outpatient services, except those identified 
in section I.B. of this proposed rule and certain inpatient services 
covered under Medicare Part B for beneficiaries who are entitled to 
Part B benefits but who have exhausted them or otherwise are not 
entitled to them. In addition, the OPPS applies to partial 
hospitalization services furnished by community mental health centers 
(CMHCs).

[[Page 50451]]

    The OPPS rate is an unadjusted national payment amount that 
includes the Medicare payment and the beneficiary copayment. This rate 
is divided into a labor-related amount and a nonlabor-related amount. 
The labor-related amount is adjusted for area wage differences using 
the inpatient hospital wage index value for the locality in which the 
hospital or CMHC is located.
    All services and items within an APC are comparable clinically and 
with respect to resource use (section 1833(t)(2)(B) of the Act). In 
accordance with section 1833(t)(2) of the Act, subject to certain 
exceptions, services and items within an APC group cannot be considered 
comparable with respect to the use of resources if the highest median 
(or mean cost, if elected by the Secretary) for an item or service in 
the APC is more than 2 times greater than the lowest median cost for an 
item or service with the same APC (referred to as the ``2 times 
rule''). In implementing this provision, we use the median cost of the 
item or service assigned to an APC.
    Special payments under the OPPS may be made for new technology 
items and services in one of two ways. Section 1833(t)(6) of the Act 
provides for temporary additional payments or ``transitional pass-
through payments'' for certain drugs, biological agents, brachytherapy 
devices used for the treatment of cancer, and categories of medical 
devices for at least 2 but not more than 3 years. For new technology 
services that are not eligible for pass-through payments and for which 
we lack sufficient data to appropriately assign them to a clinical APC, 
we have established special APC groups based on costs, which we refer 
to as APC cost bands. These cost bands allow us to price these new 
procedures more appropriately and consistently. Like the pass-through 
payments, these special payments for new technology services are also 
temporary; that is, we retain a service within a new technology APC 
group until we acquire adequate data to assign it to a clinically 
appropriate APC.

B. Excluded OPPS Services and Hospitals

    Section 1833(t)(1)(B)(i) of the Act authorizes the Secretary to 
designate the hospital outpatient services that are paid under the 
OPPS. While most hospital outpatient services are payable under the 
OPPS, section 1833(t)(1)(B)(iv) of the Act excluded payment for 
ambulance, physical and occupational therapy, and speech-language 
pathology services, for which payment is made under a fee schedule. The 
Secretary exercised the broad authority granted under the statute to 
exclude from the OPPS those services that are already paid under fee 
schedules or other payment systems. Such excluded services include, for 
example, the professional services of physicians and nonphysician 
practitioners paid under the Medicare physician fee schedule; 
laboratory services paid under the clinical diagnostic laboratory fee 
schedule; services for beneficiaries with end-stage renal disease 
(ESRD) that are paid under the ESRD composite rate; and services and 
procedures that require an inpatient stay that are paid under the 
hospital inpatient prospective payment system (IPPS). We set forth the 
services that are excluded from payment under the OPPS in Sec.  419.22 
of the regulations.
    Under Sec.  419.20 of the regulations, we specify the types of 
hospitals and entities that are excluded from payment under the OPPS. 
These excluded entities include Maryland hospitals, but only for 
services that are paid under a cost containment waiver in accordance 
with section 1814(b)(3) of the Act; critical access hospitals (CAHs); 
hospitals located outside of the 50 States, the District of Columbia, 
and Puerto Rico; and Indian Health Service hospitals.

C. Prior Rulemaking

    On April 7, 2000, we published in the Federal Register a final rule 
with comment period (65 FR 18434) to implement a prospective payment 
system for hospital outpatient services. The hospital OPPS was first 
implemented for services furnished on or after August 1, 2000. Section 
1833(t)(9) of the Act requires the Secretary to review certain 
components of the OPPS not less often than annually and to revise the 
groups, relative payment weights, and other adjustments to take into 
account changes in medical practice, changes in technology, and the 
addition of new services, new cost data, and other relevant information 
and factors. Since implementing the OPPS, we have published final rules 
in the Federal Register annually to implement statutory requirements 
and changes arising from our experience with this system. For a full 
discussion of the changes to the OPPS, we refer readers to these 
Federal Register final rules.\1\
---------------------------------------------------------------------------

    \1\ Interim final rule with comment period, August 3, 2000 (65 
FR 47670); interim final rule with comment period, November 13, 2000 
(65 FR 67798); final rule and interim final rule with comment 
period, November 2, 2001 (66 FR 55850 and 55857); final rule, 
November 30, 2001 (66 FR 59856); final rule, December 31, 2001 (66 
FR 67494); final rule, March 1, 2002 (67 FR 9556); final rule, 
November 1, 2002 (67 FR 66718); interim final rule with comment 
period, November 7, 2003 (68 FR 63398); and interim final rule with 
comment period, January 6, 2004 (69 FR 820).
---------------------------------------------------------------------------

    On November 7, 2003, we published a final rule with comment period 
in the Federal Register (68 FR 63398) that revised the OPPS to update 
the payment weights and conversion factor for services payable under 
the calendar year (CY) 2004 OPPS on the basis of claims data from April 
1, 2002 through December 31, 2002. Subsequent to publishing the 
November 7, 2003 final rule with comment period, we published a 
correction of the final rule with comment period on December 31, 2003 
(68 FR 75442). That document corrected technical errors in the November 
7, 2003 rule and included responses to a number of public comments that 
were inadvertently omitted from that rule.
    On January 6, 2004, we published in the Federal Register an interim 
final rule with comment period (69 FR 820) that implemented provisions 
of Pub. L. 108-173 that affected payments made under the OPPS, 
effective January 1, 2004. We will finalize this interim final rule and 
address public comments associated with that rule when we finalize this 
proposed rule.

D. APC Advisory Panel

1. Authority of the APC Panel
    Section 1833(t)(9)(A) of the Act, as amended by section 201(h) of 
the BBRA of 1999, requires that we consult with an outside panel of 
experts to review the clinical integrity of the payment groups and 
weights under the OPPS. The Advisory Panel on APC Groups (the APC 
Panel), discussed under section I.D.2. of this preamble, fulfills this 
requirement. The Act further specifies that the Panel will act in an 
advisory capacity. This expert panel, which is to be composed of 15 
representatives of providers subject to the OPPS (currently employed 
full-time, not consultants, in their respective areas of expertise), 
reviews and advises us about the clinical integrity of the APC groups 
and their weights. The APC Panel is not restricted to using our data 
and may use data collected or developed by organizations outside the 
Department in conducting its review.
2. Establishment of the APC Panel
    On November 21, 2000, the Secretary signed the charter establishing 
the Advisory Panel on APC Groups. The APC Panel is technical in nature 
and is governed by the provisions of the Federal Advisory Committee Act 
(FACA), as amended (Pub. L. 92-463). On November 1, 2002, the Secretary

[[Page 50452]]

renewed the charter. The renewed charter indicates that the APC Panel 
continues to be technical in nature, is governed by the provisions of 
the FACA, may convene up to three meetings per year, and is chaired by 
a Federal official.
    Originally, in establishing the APC Panel, we solicited members in 
a notice published in the Federal Register on December 5, 2000 (65 FR 
75943). We received applications from more than 115 individuals 
nominating either colleagues or themselves. After carefully reviewing 
the applications, we chose 15 highly qualified individuals to serve on 
the APC Panel. Because of the loss of four APC Panel members due to the 
expiration of terms of office on March 31, 2004, we published a Federal 
Register notice on January 23, 2004 (69 FR 3370) that solicited 
nominations for APC Panel membership. From the 24 nominations that we 
received, we chose four new members. The entire APC Panel membership is 
identified on the CMS website at http://www.cms.hhs.gov/faca/apc/apcmem.asp.

3. APC Panel Meetings and Organizational Structure
    The APC Panel first met on February 27, February 28, and March 1, 
2001. Since that initial meeting, the APC Panel has held four 
subsequent meetings, with the last meeting taking place on February 18, 
19, and 20, 2004. Prior to each of these biennial meetings, we 
published a notice in the Federal Register to announce each meeting 
and, when necessary, to solicit nominations for APC Panel membership. 
For a more detailed discussion about these announcements, refer to the 
following Federal Register notices: December 5, 2000 (65 FR 75943), 
December 14, 2001 (66 FR 64838), December 27, 2002 (67 FR 79107), July 
25, 2003 (68 FR 44089), and December 24, 2003 (68 FR 74621).
    During these meetings, the APC Panel established its operational 
structure which, in part, includes the use of three subcommittees to 
facilitate its required APC review process. Currently, the three 
subcommittees are the Data Subcommittee, the Observation Subcommittee, 
and the Packaging Subcommittee. The Data Subcommittee is responsible 
for studying the data issues confronting the APC Panel and for 
recommending viable options for resolving them. This subcommittee was 
initially established on April 23, 2001, as the Research Subcommittee 
and reestablished as the Data Subcommittee on April 13, 2004. The 
Observation Subcommittee (established on June 24, 2003, and 
reestablished with new members on March 8, 2004) reviews and makes 
recommendations to the APC Panel on all issues pertaining to 
observation services paid under the OPPS, such as coding and 
operational issues. The Packaging Subcommittee, which was established 
on March 8, 2004, studies and makes recommendations on issues 
pertaining to services that are not separately payable under the OPPS 
but are bundled or packaged into the APC payment. Each of these 
subcommittees was established by a majority vote of the APC Panel 
during a scheduled annual or biennial APC Panel meeting. All 
subcommittee recommendations are discussed and voted upon by the full 
APC Panel.
    For a detailed discussion of the APC Panel meetings, refer to the 
hospital OPPS final rules cited in section I.C. of this preamble. A 
full discussion of the APC Panel's February 2004 meeting and the 
resulting recommendations is included in sections II., III., IV., V., 
and VI. of this preamble.

E. Provisions of the Medicare Prescription Drug, Improvement, and 
Modernization Act of 2003

    On December 8, 2003, the Medicare Prescription Drug, Improvement, 
and Modernization Act of 2003 (MMA), Pub. L. 108-173, was enacted. Pub. 
L. 108-173 made changes to the Act relating to the Medicare OPPS. In a 
January 6, 2004 interim final rule with comment period, we implemented 
provisions of Pub. L. 108-173 relating to the OPPS that were effective 
for CY 2004. In this proposed rule, we are proposing to implement the 
following sections of Pub. L. 108-173 that are effective for CY 2005:
     Section 611, which provides for Medicare coverage of an 
initial preventive physical examination under Part B, subject to the 
applicable deductible and coinsurance, as an outpatient department 
(OPD) service payable under the OPPS. The provisions of section 611 
apply to services furnished on or after January 1, 2005, but only for 
individuals whose coverage period under Medicare Part B begins on or 
after that date.
     Section 614, which provides that screening mammography and 
diagnostic mammography services are excluded from payment under the 
OPPS. This amendment applies to screening mammography services 
furnished on or after the date of enactment of Pub. L. 108-173 (that 
is, December 8, 2003), and in the case of diagnostic mammography, to 
services furnished on or after January 1, 2005.
     Section 621(a)(1), which requires special classification 
of certain separately paid radiopharmaceutical agents and drugs or 
biologicals, and specifies the pass-through payment percentages, 
effective for services furnished on or after January 1, 2005, for the 
three categories of ``specified covered OPD drugs'' defined in the 
statute: sole source drug; innovator multiple source drug; and 
noninnovator multiple source drug. In addition, payment for these drugs 
for CYs 2004 and 2005 does not have to be made in a budget neutral 
manner.
     Section 621(a)(2), which specifies the reduced threshold 
for the establishment of separate APCs with respect to drugs or 
biologicals from $150 to $50 per administration for drugs and 
biologicals furnished in CYs 2005 and 2006.
     Section 621(a)(3), which excludes separate drug APCs from 
outlier payments. Specifically, no additional payment will be made in 
the case of APC groups established separately for drugs and 
biologicals.
     Section 621(b), which requires that all devices of 
brachytherapy consisting of a seed or seeds (or radioactive source) 
furnished on or after January 1, 2004, and before January 1, 2007, be 
paid based on the hospital's charges for each device, adjusted to cost. 
This provision also requires that these brachytherapy services be 
excluded from outlier payments.

F. Summary of Major Content of This Proposed Rule

    In this proposed rule, we are setting forth proposed changes to the 
Medicare hospital OPPS. These changes would be effective for services 
furnished on or after January 1, 2005. The following is a summary of 
the major changes that we are proposing to make:
1. Proposed Changes to the APCs Groups
    As required by section 1833(t)(9)(A) of the Act, we are proposing 
the annual update of the APC groups and the relative payment weights. 
This section also requires that we consult with an outside panel of 
experts, the Advisory Panel on APC Groups, to review the clinical 
integrity of the groups and weights under the OPPS. Based on analyses 
of Medicare claims data and recommendations of the APC Panel, we are 
proposing to establish a number of new APCs and to make changes to the 
assignment of HCPCS codes under a number of existing APCs. Our proposed 
APC changes for CY 2005 are set forth in section II. of this preamble.
    We also discuss the application of the 2 times rule and proposed 
exceptions to it; coding for stereotactic radiosurgery services; the 
proposed movement of

[[Page 50453]]

procedures from the new technology APCs; the proposed changes to the 
list of procedures that will be paid as inpatient services; and the 
proposed additions of new procedure codes to the APCs.
2. Recalibrations of APC Relative Payment Weights
    In section III. of this preamble, we discuss the methodology used 
to recalibrate the proposed APC relative payment weights and set forth 
the proposed recalibration of the relative weights for CY 2005.
3. Proposed Payment Changes for Devices
    In section IV. of this preamble, we discuss proposed changes to the 
pass-through payment for devices and the methodology used to reduce 
transitional pass-through payments to offset costs packaged into APC 
groups.
4. Proposed Payment Changes for Drugs, Biologicals, Radiopharmaceutical 
Agents, and Blood and Blood Products
    In section V. of this preamble, we discuss our proposed payment 
changes for drugs, biologicals, radiopharmaceutical agents, and blood 
and blood products.
5. Pro Rata Reduction for Transitional Pass-Through Drugs, Biologicals, 
and Devices
    In section VI. of this preamble, we discuss the proposed 
methodology for measuring whether there should be an estimated pro rata 
reduction for transitional pass-through drugs, biologicals, and devices 
for CY 2005.
6. Other Policy Decisions and Proposed Policy Changes
    In section VII. of this preamble, we present our proposals for CY 
2005 regarding the following:
     Update of statewide default cost-to-charge ratios.
     A conforming change to the regulation relating to the use 
of the first available cost reporting period ending after 1996 and 
before 2001 for determining a provider's payment-to-cost ratio to 
calculate transitional corridor payments for hospitals paid under the 
OPPS that did not have a 1996 cost report.
     Proposed changes in the status indicators and comment 
indicators assigned to APCs for CY 2005.
     Proposed elimination of the diagnostic tests criteria as a 
requirement for hospitals to qualify for separate payment of 
observation services under APC 0339 (Observation) and changes to the 
guidelines to hospitals for counting patients time spent in observation 
care.
     Proposed payment under the OPPS for certain procedures 
currently assigned to the inpatient list.
     Proposed strategy for giving the public notice of new 
implementation guidelines for new evaluation and management codes.
     Proposed addition of three new HCPCS codes and descriptors 
for brachytherapy sources that would be paid separately, pursuant to 
Pub. L. 108-173.
     Proposed modification of the HCPCS code descriptors for 
brachytherapy source descriptors for which units of payment are not 
already delineated.
     Proposed payment for services furnished emergently to an 
outpatient who dies before admission to a hospital as an inpatient.
7. Proposed Conversion Factor Update for CY 2005
    As required by section 1833(5)(3)(C)(ii) of the Act, under section 
VIII. of this preamble, we are proposing to update the conversion 
factor used to determine payment rates under the OPPS for CY 2005.
8. Proposed Wage Index Changes for CY 2005
    In section IX. of this preamble, we discuss the proposed retention 
of our current policy to apply the IPPS wage indices to wage adjust the 
APC median costs in determining the OPPS payment rate and the copayment 
standardized amount. These indices reflect proposed major changes for 
CY 2005 relating to hospital labor market areas as a result of OMB 
revised definitions of geographical statistical areas; hospital 
reclassifications and redesignations, including the one-time 
reclassifications under section 508 of Pub. L. 108-173; and the wage 
index adjustment based on commuting patterns of hospital employees 
under section 505 of Pub. L. 108-173.
9. Determination of Payment Rates and Outlier Payments for CY 2005
    In section X. of this preamble, we discuss how APC payment rates 
are calculated and how the payment rates are adjusted to reflect 
geographic differences in labor-related costs. This section also 
discusses proposed changes in the way we calculate outlier payments for 
CY 2005.
10. MedPAC Recommendations
    Under section 1805(b) of the Act, the Medicare Payment Advisory 
Committee (MedPAC) is required to submit a report to Congress, no later 
than March 1 of each year, that reviews and makes recommendations on 
Medicare payment policies. This annual report makes recommendations 
concerning the hospital outpatient prospective payment system. In 
section XII. of this preamble, we discuss the MedPAC recommendations. 
For further information relating specifically to the MedPAC March 1, 
2004 report or to obtain a copy of the report, visit MedPAC's Web site 
at: http://www.medpac.gov.

11. Regulatory Impact Analysis
    In section XV. of this preamble, we set forth our analysis of the 
impact that the proposed changes contained in this proposed rule would 
have on affected hospitals and CMHCs.

II. Proposed Changes Related to Ambulatory Payment Classifications 
(APCs)

    [If you choose to comment on issues in this section, please 
indicate the caption ``APC Groups'' at the beginning of your comment.]
    Section 1833(t)(2)(A) of the Act requires the Secretary to develop 
a classification system for covered hospital outpatient services. 
Section 1833(t)(2)(B) provides that this classification system may be 
composed of groups of services, so that services within each group are 
comparable clinically and with respect to the use of resources. In 
accordance with these provisions, we developed a grouping 
classification system, referred to as the Ambulatory Payment 
Classifications Groups or APCs, as set forth in Sec.  419.31 of the 
regulations. We use Healthcare Common Procedure Coding System (HCPCS) 
codes and descriptors to identify and group the services within each 
APC. The APCs are organized such that each group is homogeneous both 
clinically and in terms of resource use. (However, new technology APCs 
that are temporary groups for certain approved services are structured 
based on cost rather clinically homogeneity.) Using this classification 
system, we have established distinct groups of surgical, diagnostic, 
and partial hospitalization services, and medical visits. Because of 
the transitional pass-through provisions, we also have developed 
separate APC groups for certain medical devices, drugs, biologicals, 
radiopharmaceuticals, and devices of brachytherapy.
    We have packaged into each procedure or service within an APC the 
cost associated with those items or services that are directly related 
and integral to performing a procedure or furnishing a service. 
Therefore, we would not make separate payment for

[[Page 50454]]

packaged items or services. For example, packaged items and services 
include: use of an operating, treatment, or procedure room; use of a 
recovery room; use of an observation bed; anesthesia; medical/surgical 
supplies; pharmaceuticals (other than those for which additional 
payment may be allowed under the transitional pass-through provisions 
discussed in section V. of this preamble); and incidental services such 
as venipuncture. Our packaging methodology is discussed in section 
IV.B.3. of this proposed rule.

A. Proposed APC Changes: General

    Under the OPPS, we pay for hospital outpatient services on a rate-
per-service basis that varies according to the APC group to which the 
service is assigned. Each APC weight represents the median hospital 
cost of the services included in that APC relative to the median 
hospital cost of the services included in APC 601, Mid-Level Clinic 
visits. The APC weights are scaled to APC 601 because a mid-level 
clinic visit is one of the most frequently performed services in the 
outpatient setting.
    Section 1833(t)(9)(A) of the Act requires the Secretary to review 
the components of the OPPS not less than annually and to revise the 
groups and relative payment weights and make other adjustments to take 
into account changes in medical practice, changes in technology, and 
the addition of new services, new cost data, and other relevant 
information and factors. Section 1833(t)(9)(A) of the Act, as amended 
by section 201(h) of the BBRA of 1999, also requires the Secretary, 
beginning in CY 2001, to consult with an outside panel of experts to 
review the APC groups and the relative payment weights.
    Finally, section 1833(t)(2) of the Act provides that, subject to 
certain exceptions, the items and services within an APC group cannot 
be considered comparable with respect to the use of resources if the 
highest median (or mean cost, if elected by the Secretary) for an item 
or service in the group is more than 2 times greater than the lowest 
median cost for an item or service within the same group (referred to 
as the ``2 times rule''). We use the median cost of the item or service 
in implementing this provision. The statute authorizes the Secretary to 
make exceptions to the 2 times rule in unusual cases, such as low 
volume items and services.
    Section 419.31 of the regulations sets forth the requirements for 
the APC system and determination of the payment weights. In this 
section, we discuss the changes that we are proposing to the APC 
groups; the APC Panel's review and recommendations and our proposals in 
response to those recommendations; the application of the 2 times rule 
and proposed exceptions to it; coding for stereotactic radiosurgery 
services; the proposed movement of procedures from the new technology 
APCs; the proposed changes to the inpatient list; and the proposed 
additions of new procedures codes to the APCs.

B. APC Panel Review and Recommendations

    As stated above, the APC Panel met on February 18, 19, and 20, 
2004, to discuss the revised APCs for the CY 2005 OPPS. In preparation 
for that meeting, we published a notice in the Federal Register on 
December 24, 2004 (68 FR 74621), to announce the location, date, and 
time of the meeting; the agenda items; and the fact that the meeting 
was open to the public. In that notice, we solicited public comment 
specifically on the items included on the agenda for that meeting. We 
also provided information about the APC Panel meeting on the CMS 
website: http://www.cms.hhs.gov/faca/apc/panel.

    Oral presentations and written comments submitted for the February 
2004 APC Panel meeting met, at a minimum, the adopted guidelines for 
presentations set forth in the Federal Register document (68 FR 74621). 
Below is a summary of the APC issues discussed by the APC Panel, its 
recommendations, and our proposals with respect to those 
recommendations. The discussion in this section is limited to proposed 
APC changes regarding APCs other than those that violate the 2 times 
rule and those that represent drugs, biologicals, and transitional 
pass-through devices, or those that are new technology APCs. The 
specific APC Panel review and recommendations applicable to those APCs 
are discussed in sections II.C., IV., III., and II.F., respectively, of 
the preamble to this proposed rule. In conducting its APC review, the 
APC Panel heard testimony and received evidence in support of the 
testimonies from a number of interested parties. The APC Panel also 
used hospital outpatient claims data for the period January 1, 2003, 
through September 30, 2003, that provided, at a minimum, median costs 
for the APC structure in place in CY 2004 and that was based on cost-
to-charge ratios used for setting the CY 2004 payment rates. The data 
set presented to the APC Panel represented 9 months of the CY 2003 data 
that we are proposing to use to recalibrate the APC relative weights 
and to calculate the proposed APC payment rates for CY 2005. For this 
discussion, we are using the APC titles as published in our November 7, 
2003 final rule with comment period, which were the APC titles that 
existed when the APC Panel met in February 2004. Because we are 
proposing to retitle some of the APCs, the titles used in this 
discussion may not be the same as those listed in Addendum A to this 
proposed rule.
1. APC 0018: Biopsy of Skin/Puncture of Lesion
    One presenter requested that the APC Panel recommend moving CPT 
tracking codes 0046T (Catheter lavage, mammary duct(s)) and 0047T (Each 
additional duct) from APC 0018 and placing them in an APC that more 
accurately reflects each of the procedures. The APC Panel recommended 
that we reassign CPT codes 0046T and 0047T to APC 0021, Level III 
Excision/Biopsy.
    We are proposing to accept the APC Panel's recommendation.
2. Level I and II Arthroscopy
APC 0041: Level I Arthroscopy
APC 0042: Level II Arthroscopy

    We testified before the APC Panel regarding a comment that we 
received in 2003 requesting that we reassign CPT code 29827 
(Arthroscopy, shoulder with rotator cuff repair) from APC 0041 to APC 
0042, based on its similarity to CPT 29826 (Arthroscopy, shoulder 
decompression of subacromial space with partial acromioplasty without 
coracoacromial release). Our clinical staff considered the request and 
determined that APCs 0041 and 0042 should be reconfigured to improve 
clinical homogeneity. An APC Panel presenter provided evidence to 
support moving CPT code 29827 to an APC that would more accurately 
recognize the complexity of that procedure. We requested the APC 
Panel's recommendation regarding a total revision of these two APCs.
    The APC Panel recommended that we reevaluate the codes in APCs 0041 
and 0042 and propose restructuring that would improve the clinical 
homogeneity in the two APCs.
    We are proposing to accept the APC Panel's recommendation and to 
revise APCs 0041 and 0042 as shown in Tables 1 and 2 below.
BILLING CODE 4120-01-P

3. Angiography and Venography Except Extremity
APC 0279: Level II Angiography and Venography Except Extremity
APC 0280: Level III Angiography and Venography Except Extremity
APC 0668: Level I Angiography and Venography Except Extremity

    As requested by the APC Panel, we presented our proposal for 
reconfiguring APCs 0279, 0280, and 0668 that reflected changes based on 
prior input with outside clinical experts. The APC Panel had previously 
reviewed these APCs during its January 2003 meeting and had recommended 
that we not restructure these three APCs until we received input from 
clinical experts in the field. When we updated the APC groups in CY 
2003, we accepted the APC Panel's recommendation and made no changes to 
APCs 0279, 0280, and 0668.
    A review of these APCs was prompted by a commenter who requested 
that we move CPT code 75978 (Repair venous blockage) from APC 0668 to 
APC 0280 and that we move CPT code 75774 (Artery x-ray, each vessel) 
from APC 0668 to APC 0279. The commenter submitted evidence in support 
of these requests and testified before the APC Panel regarding the 
common use of CPT code 75978 for treating dialysis patients and the 
often required multiple intraoperative attempts to succeed with this 
procedure for such patients.
    After receiving input from the clinical experts, we determined that 
these three APCs should be revised to improve their clinical 
homogeneity. We presented our proposed restructuring of APCs 0279, 
0280, and 0668 to the APC Panel. The APC Panel concurred with our 
proposal.
    In addition, subsequent to the APC Panel meeting, we discovered 
several procedures in these APCs that were more appropriately placed in 
another APC in order to remedy any 2 times rule violations. Tables 3, 
4, and 5 reflect those additional APC reassignments as well as those we 
presented to the APC Panel in February 2004.

C. Limits on Variations Within APCs: Proposed Application of the 2 
Times Rule

    Section 1833(t)(2) of the Act provides that the items and services 
within an APC group cannot be considered comparable with respect to the 
use of resources if the median of the highest cost item or service 
within an APC group is more than 2 times greater than the median of the 
lowest cost item or service within that same group. However, the 
statute authorizes the Secretary to make exceptions to this limit on 
the variation of costs within each APC group in unusual cases such as 
low volume items and services. No exception may be made in the case of 
a drug or biological that has been designated as an orphan drug under 
section 526 of the Federal Food, Drug, and Cosmetic Act. We implemented 
this statutory provision in Sec.  419.31 of the regulations. Under this 
regulation, we elected to use the highest median cost and lowest median 
cost to determine comparability.
    During the APC Panel's February 2004 meeting, we presented data and 
information concerning a number of APCs that violate the 2 times rule 
and asked the APC Panel for its recommendation. We discuss below the 
APC Panel's recommendations specific to each of these APCs and our 
proposals in response to the APC Panel's recommendations.
1. Cardiac and Ambulatory Blood Pressure Monitoring
APC 0097: Cardiac and Ambulatory Blood Pressure Monitoring

    We expressed concern to the APC Panel that APC 0097 appears to 
violate the 2 times rule. We sought the APC Panel's recommendation on 
revising the APC to address the violation. Based on clinical 
homogeneity considerations, the APC Panel recommended that we not 
restructure APC 0097 for CY 2005.
    We are proposing to accept the APC Panel's recommendation that we 
make no changes to APC 0097 for CY 2005.
2. Electrocardiograms
APC 0099: Electrocardiograms

    We expressed concern to the APC Panel that APC 0099 appears to 
violate the 2 times rule. We asked the APC Panel to recommend options 
for resolving this violation. Based on clinical homogeneity 
considerations, the APC Panel recommended that we not alter the 
structure of APC 0099 for CY 2005.
    We are proposing to accept the APC Panel's recommendation that we 
make no changes to APC 0099 for CY 2005.
3. Excision/Biopsy
APC 0019: Level I Excision/Biopsy
APC 0020: Level II Excision/Biopsy
APC 0021: Level III Excision/Biopsy

    We expressed concern to the APC Panel that APC 0019 appears to 
violate the 2 times rule. We advised the APC Panel that this violation 
was not evident in CY 2004 because the CY 2002 median cost data used in 
calculating the CY 2004 APC updates supported moving CPT codes 11404 
(Removal of skin lesion) and 11623 (Removal of skin lesion) from APC 
0020 and APC 0021. However, based on the CY 2003 data reviewed by the 
APC Panel, APC 0019 would violate the 2 times rule. Therefore, we asked 
the APC Panel to recommend an approach to resolve the violation. We 
asked the APC Panel if we should leave this APC as is; divide APC 0019 
into two separate APCs; or move some codes in APC 0019 to higher level

[[Page 50459]]

excision/biopsy APCs. In making its recommendation, the APC Panel noted 
that the 2 times violation in APC 0019 was minor, and recommended that 
we not modify APC 0019.
    We are proposing to accept the APC Panel's recommendation to not 
make any modifications to APC 0019 for CY 2005.
4. Posterior Segment Eye Procedures
APC 0235: Level I Posterior Segment Eye Procedures

    We expressed concern to the APC Panel that APC 0235 appears to 
violate the 2 times rule. At the August 2003 APC Panel meeting, the APC 
Panel recommended that we monitor the data for APC 0235 for review at 
its February 2004 meeting. In order to address the apparent violation, 
we asked the APC Panel to consider moving a few CPT codes from APC 0235 
into a higher level posterior segment eye procedure APC. The APC Panel 
noted that the 2 times violation in APC 0235 was minor, and recommended 
that we not change APC 0235.
    We are proposing to accept the APC Panel's recommendation that we 
make no changes to the structure of APC 0235 for CY 2005.
5. Laparoscopy
APC 0130: Level I Laparoscopy
APC 0131: Level II Laparoscopy

    We expressed concern to the APC Panel that APC 0130 appears to 
violate the 2 times rule. We suggested moving CPT code 44970 
(Laparoscopy, appendectomy) from APC 0130 to APC 0131. The APC Panel 
recommended that we make this change.
    We are proposing to accept the APC Panel's recommendation to move 
CPT code 44970 from APC 0130 to APC 0131.
6. Anal/Rectal Procedures
APC 0148: Level I Anal/Rectal Procedure
APC 0155: Level II Anal/Rectal Procedure
APC 0149: Level III Anal/Rectal Procedure
APC 0150: Level IV Anal/Rectal Procedure
    We expressed concern to the APC Panel that APC 0148 appears to 
violate the 2 times rule. We suggested moving CPT code 46020 (Placement 
of seton) from APC 0148 to a higher level anal/rectal procedure APC. 
The APC Panel reviewed the four anal/rectal APCs (APC 0148, 0149, 0150, 
and 0155) and recommended moving CPT codes 46020 and 46706 (Repair of 
anal fistula with glue) from APC 0148 to APC 0150. The APC Panel also 
recommended moving CPT codes 45005 (Drainage of rectal abscess) and 
45020 (Drainage of rectal abscess) from APC 0148 to APC 0155.
    We are proposing to accept the APC Panel's recommendations specific 
to APC 0148. Our proposed movement of CPT codes from APC 0148 to APCs 
0150 and 0155 is shown in the Table 6 below.
[GRAPHIC] [TIFF OMITTED] TP16AU04.004

7. Nerve Injections
APC 0204: Level I Nerve Injections
APC 0206: Level II Nerve Injections
APC 0207: Level III Nerve Injections
APC 0203: Level IV Nerve Injections

    We again expressed concern to the APC Panel that APC 0203 and APC 
0207 appear to violate the 2 times rule. We previously discussed this 
issue at the APC Panel's CY 2003 meeting. During the CY 2003 meeting, 
the APC Panel recommended that we gather additional data on procedures 
assigned to APC 0203 and APC 0207 before proposing to reconfigure them 
to attempt to eliminate the 2 times rule violation. The APC Panel 
believed then that the structure of these two APCs as proposed in the 
August 2003 OPPS proposed rule were more clinically cohesive than those 
set forth in the November 2002 OPPS final rule. During the February 
2004 meeting, we presented other information for the APC Panel to 
review in making its recommendation.
    After careful consideration of the new data, the APC Panel 
recommended moving CPTs 64420 (Nerve block injection, intercostal 
nerve), 64630 (Injection treatment of nerve), 64640 (Injection 
treatment of nerve), and 62280 (Treatment of a spinal cord lesion) from 
APC 0207 to APC 0206. The APC Panel also recommended moving CPT code 
62282 (Treatment of a spinal canal lesion) from APC 0207 to APC 0203.
    After reviewing more recent, complete calendar year data, we are 
proposing to accept some of the APC Panel's recommendation 
(specifically, move CPTs 64630 and 64640 from APC 0207 to APC 0206), 
and to make some other changes that we believe are appropriate to 
improve the nerve injection APC's clinical and resource homogeneity. 
Our proposed nerve injection APC assignments are shown in Tables 7, 8, 
and 9 below.

8. Anterior Segment Eye Procedures
APC 0232: Level I Anterior Segment Eye Procedures
APC 0233: Level II Anterior Segment Eye Procedures

    We expressed concern to the APC Panel that APC 0233 appears to 
violate the 2 times rule. We suggested moving CPT codes 65286 (Repair 
of eye wound), 66030 (Injection treatment of eye), and 66625 (Removal 
of iris) from APC 0233 to APC 0232. The APC Panel agreed and 
recommended that we move CPT codes 65286, 66030, and 66625 from APC 
0233 to APC 0232.
    We are proposing to accept the APC Panel's recommendation and to 
reassign these three codes as shown in Table 10.
[GRAPHIC] [TIFF OMITTED] TP16AU04.007

9. Pathology
APC 0343: Level II Pathology
APC 0344: Level III Pathology

    We expressed concern to the APC Panel that APC 0343 appears to 
violate the 2 times rule. We suggested moving CPT code 88346 
(Immunoflourescent study) from APC 0343 to APC 0344. The APC Panel 
concurred with our proposal.
    We are proposing to accept the APC Panel's recommendation and to 
move CPT code 88346 from APC 0343 to APC 0344.
10. Immunizations
APC 0355: Level III Immunizations (proposed for CY 2005: Level I 
Immunizations)
APC 0356: Level IV Immunizations (proposed for CY 2005: Level II 
Immunizations)

    We expressed concern to the APC Panel that APCs 0355 and 0356 
appear to violate the 2 times rule. In order to eliminate this 
violation, we suggested moving CPT 90636 (Hepatitis A/Hepatitis B 
vaccine, adult dose, intramuscular use) from APC 0355 to APC 0356. We 
also suggested moving CPT codes 90375 (Rabies immune globulin, 
intramuscular or subcutaneous), 90740 (Hepatitis B vaccine, dialysis or 
immunosuppressed patient, intramuscular), 90723 (Diphtheria-pertussis-
tetanus, Hepatitis B, Polio vaccine, intramuscular), and 90693 (Typhoid 
vaccine, AKD, subcutaneous) from APC 0356 to APC 0355.
    The APC Panel recommended moving CPT 90636 from APC 0355 to APC 
0356 and CPT codes 90740, 90723, and 90693 from APC 0356 to APC 0355. 
The APC Panel delayed making a recommendation on CPT 90375 and 
requested that we collect additional cost data on this procedure for 
discussion at the next scheduled APC Panel meeting.
    We are proposing to accept the APC Panel's recommended changes to 
move CPT code 90740 from APC 0356 to 0355, and to move CPT code 90636 
from 0355 to 0356. However, based on our review of more recent claims 
data than were available to the APC Panel, we determined that the 
medians for CPT

[[Page 50462]]

codes 90693 and 90375 are below the $50 drug packaging threshold. 
Therefore, we are also proposing to package both CPT codes 90693 and 
90375. We are proposing to change CPT code 90723 to status indicator 
``e'' because it is not payable by Medicare.

11. Pulmonary Tests
APC 0367: Level I Pulmonary Tests
APC 0368: Level II Pulmonary Tests

APC 0369: Level III Pulmonary Tests
    We expressed concern to the APC Panel that APC 0369 appears to 
violate the 2 times rule. We suggested moving CPT code 94015 (Patient 
recorded spirometry) from APC 0369 to APC 0367. The APC Panel concurred 
with our proposal.
    We are proposing to accept the APC Panel's recommendation and to 
move CPT code 94015 from APC 0369 to APC 0367.
    In addition, during our analysis of more recent claims data 
following the APC Panel meeting, we noted that APC 0367 violated the 2 
times rules. Therefore, we are proposing to reassign CPT codes 94375, 
94750, 94450, 94014, 94690, and 93740 to APC 0368.
[GRAPHIC] [TIFF OMITTED] TP16AU04.009

12. Clinic Visits
APC 0600: Low Level Clinic Visits

    We expressed concern to the APC Panel that APC 0600 appears to 
violate the 2 times rule. We suggested moving HCPS code G0264 
(Assessment other than CHF, chest pain, asthma) to a higher level 
clinic visit. The APC Panel recommended that we not make any changes to 
APC 0600.
    We are proposing to accept this recommendation and not make any 
changes to APC 0600 for CY 2005.

D. Proposed Exceptions to the 2 Times Rule

[If you choose to comment on issues in this section please indicate the 
caption ``2 Times Rule'' at the beginning of your comment.]
    As discussed earlier, the Secretary is authorized to make 
exceptions to the 2 times limit on the variation of costs within each 
APC group in unusual cases such as low volume items and services.
    Taking into account the APC changes that we are proposing for CY 
2005 based on the APC Panel recommendations discussed in section II.C. 
of this preamble and the use of CY 2003 claims data to calculate the 
median cost of procedures classified in the APCs, we reviewed all the 
APCs to determine which of them would not meet the 2

[[Page 50463]]

times limit. We used the following criteria when deciding whether to 
propose exceptions to the 2 times rule for affected APCs:

 Resource homogeneity
 Clinical homogeneity
 Hospital concentration
 Frequency of service (volume)
 Opportunity for upcoding and code fragments.

    For a detailed discussion of these criteria, refer to the April 7, 
2000 OPPS final rule with comment period (65 FR 18457).
    Table 13 contains the APCs that we are proposing to exempt from the 
2 times rule based on the criteria cited above. In cases in which a 
recommendation of the APC Panel appeared to result in or allow a 
violation of the 2 times rule, we generally accepted the APC Panel's 
recommendation because these recommendations were based on explicit 
consideration of resource use, clinical homogeneity, hospital 
specialization, and the quality of the data used to determine the APC 
payment rates that we are proposing for CY 2005. The median cost for 
hospital outpatient services for these and all other APCs can be found 
at web site: http//http://www.cms.hhs.gov.

E. Coding for Stereotactic Radiosurgery Services

[If you choose to comment on issues in this section please indicate the 
caption ``Stereotactic Radiosurgery'' at the beginning of your 
comment.]
1. Background
    In the November 7, 2003 final rule with comment period (68 FR 
63403), we discussed the APC Panel's consideration

[[Page 50465]]

of HCPCS codes G0242 (Cobalt 60-based stereotactic radiosurgery plan) 
and G0243 (Cobalt 60-based stereotactic radiosurgery delivery). At its 
August 22, 2003 meeting, the APC Panel discussed combining the coding 
for these procedures under one code, with the payment for the new code 
derived by adding the payment for HCPCS codes G0242 and G0243 together. 
The APC Panel recommended that we solicit additional input from 
professional societies representing neurosurgeons, radiation 
oncologists, and other experts in the field before recommending changes 
to the coding configuration for Cobalt 60-based stereotactic 
radiosurgery planning and delivery.
    In a correction to the November 7, 2003 final rule with comment 
period, issued on December 31, 2003 (68 FR 75442), we considered a 
commenter's request to combine HCPCS codes G0242 and G0243 into a 
single procedure code in order to accurately capture the costs of this 
treatment in a single procedure claim because the majority of patients 
receive the planning and delivery of this treatment on the same day. We 
responded to the commenter's request by explaining that several other 
commenters stated that HCPCS code G0242 was being misused to code for 
the planning phase of linear accelerator-based stereotactic 
radiosurgery planning. Because the claims data for HCPCS code G0242 
represent costs for linear accelerator-based stereotactic radiosurgery 
planning (due to misuse of the code), in addition to Cobalt 60-based 
stereotactic radiosurgery planning, we were uncertain as to how to 
combine these data with HCPCS code G0243 to determine an accurate 
payment rate for a combined code for planning and delivery of Cobalt 
60-based stereotactic radiosurgery.
    In consideration of the misuse of HCPCS code G0242 and the 
potential for causing greater confusion by combining codes G0242 and 
G0243, we created a planning code for linear accelerator-based 
stereotactic radiosurgery (G0338) to distinguish this procedure from 
Cobalt 60-based stereotactic radiosurgery planning. We maintained both 
HCPCS codes G0242 and G0243 for the planning and delivery of Cobalt 60-
based stereotactic radiosurgery treatment, consistent with the use of 
two G codes for planning (G0338) and delivery (G0173, G0251, G0339, 
G0340, as applicable) of each type of linear accelerator-based 
treatment. We indicated that we intend to maintain these new codes in 
their current new technology APCs until the payment rates could be set 
using medians from this expanded set of codes. We also stated that we 
would solicit input from the APC Panel at its February 2004 meeting.
    During the February 2004 APC Panel meeting, several presenters 
discussed with the APC Panel their rationale for requesting that HCPCS 
codes G0242 and G0243 be combined into a single procedure code. One 
presenter explained that the request to combine the codes was made 
because certain fiscal intermediaries were rejecting claims in which 
HCPCS codes G0242 and G0243 were reported with a surgery revenue code. 
Although we have not issued any national instructions to fiscal 
intermediaries to deny claims for these services if they are billed 
with a surgery revenue code, the presenter stated that we may have 
indirectly led some fiscal intermediaries to believe that Cobalt 60-
based stereotactic radiosurgery should be reported with a radiation 
therapy revenue center because the procedure is separated into a 
planning code and a delivery code, which reflect the coding pattern of 
a radiation therapy procedure rather than a single code for a surgical 
procedure. The presenter stated that because of the way that CMS has 
coded this procedure, some fiscal intermediaries have established local 
edits to deny claims in which HCPCS codes G0242 and G0243 are reported 
on a claim with a surgery revenue code.
    The APC Panel recommended that CMS work with the presenters to 
determine if any fiscal intermediaries have established local edits to 
reject claims in which HCPCS codes G0242 and G0243 are reported on a 
claim, and to determine specific reasons for any such local edits. The 
APC Panel also recommended that CMS take necessary action to ensure 
that any such claims are not being denied payment due to local edits. 
The APC Panel did not agree that the solution to ensuring payment was 
to combine HCPCS codes G0242 and G0243 into a single code, but rather 
recommended that CMS educate fiscal intermediaries as to the 
appropriate procedures for submittal of these claims for Medicare 
payment.
    In response to the concern expressed by several presenters that 
certain fiscal intermediaries were rejecting claims in which HCPCS 
codes G0242 and G0243 were reported with a surgery revenue code, we 
have worked together with these presenters to identify specific fiscal 
intermediaries who may be rejecting these claims. However, to date, we 
have been unable to identify any fiscal intermediaries who have 
established local edits that would reject claims in which HCPCS codes 
G0242 and G0243 are reported with a surgery revenue code. If a provider 
should experience a rejection of such claims in which HCPCS codes G0242 
and G0243 are reported on a claim with a surgery revenue code, they 
should contact their fiscal intermediary to determine the specific 
reason for the claim rejection.
2. Proposal for CY 2005
    For CY 2005, we are proposing to accept the APC Panel's 
recommendation to work with the presenters to ensure that claims in 
which HCPCS codes G0242 and G0243 are reported are not being unjustly 
denied payment due to local edits established by fiscal intermediaries. 
In the meantime, for CY 2005, we are proposing to maintain HCPCS code 
G0242 in new technology APC 1516 at a payment rate of $1,450, and HCPCS 
code G0243 in new technology APC 1528 at a payment rate of $5,250. 
These payment rates are the same as those established for CY 2004.

F. Proposed Movement of Procedures From New Technology APCs to 
Clinically Appropriate APCs

[If you choose to comment on issues in this section, please indicate 
the caption ``New Technology APCs'' at the beginning of your comment.]
1. Background
    In the November 30, 2001 final rule (66 FR 59903), we made final 
our proposal to change the period of time during which a service may be 
paid under a new technology APC. The April 7, 2000 final rule initially 
established the timeframe that new technology APCs would be in effect 
(65 FR 18457). Beginning in CY 2002, we have retained services within 
new technology APC groups until we have acquired adequate data that 
allow us to assign the service to a clinically appropriate APC. This 
policy allows us to move a service from a new technology APC in less 
than 2 years if sufficient data are available, and it also allows us to 
retain a service in a new technology APC for more than 3 years if 
sufficient data upon which to base a decision for reassignment have not 
been collected.
    In the November 7, 2003 final rule with comment period we 
implemented a comprehensive restructuring of the new technology APCs to 
make the payment levels more consistent (68 FR 63416). We established 
payment levels in $50, $100, and $500 intervals and expanded the number 
of new technology payment levels.
2. APC Panel Review and Recommendation
    During the APC Panel's February 2004 meeting, the APC Panel heard 
testimony from several interested parties who

[[Page 50466]]

requested specific modifications to the APCs for radiation oncology 
APC. They asked the APC Panel to make several recommendations: (1) That 
we move CPT code 77418 (Intensity-modulated radiation therapy) from APC 
0412 back into a new technology APC; (2) that we dampen, or limit, any 
possible payment reductions to APC 0301 (Level II Radiation Therapy); 
(3) that we accept more external data to evaluate costs; and (4) that 
we identify more claims that are useful for ratesetting.
    In response to the testimony presented, the APC Panel recommended 
that we reassign CPT code 77418 to the new technology APC 1510 for CY 
2005 and that we explain to providers any steps we take to limit 
payment reductions to APC 0301 so that they can better plan for future 
years during which we may decide not to apply a dampening, or payment 
reduction limitation, to the rates for APC 0301.
    We are not proposing to accept the APC Panel's recommendations 
because we believe that we have ample claims data for use in 
determining an appropriate APC payment rate for CPT code 77418. 
Moreover, we believe that the development of median cost for CPT code 
77418 based on those data would be representative of hospital bills.
    We have over 255,000 claims for this service, and over 95 percent 
were single claims that we could use for ratesetting. Moreover, the APC 
medians have been stable for the last 2 years of data. As indicated by 
our claims data, returning code 77418 to new technology APC 1510 would 
result in a payment for the service that is significantly higher than 
the resources utilized to provide it.
3. Proposal for CY 2005
    There are 24 procedures currently assigned to new technology APCs 
for which we have data adequate to support assignment into clinical 
APCs. We are proposing to reassign these procedures to clinically 
appropriate APCs. We are proposing to assign 24 of the procedures to 
clinically appropriate APCs using CY 2003 claims data to set medians on 
which payments would be based. These APCs and the proposed assignments 
are displayed below in Table 14.
    Based upon our review of the latest claims data available, we are 
proposing to move the procedures listed in Table 14 from their current 
new technology APCs to the APCs listed, as we have adequate data on 
these procedures to enable us to make the necessary APC assignment.

BILLING CODE 4120-01-P

[[Page 50467]]

[GRAPHIC] [TIFF OMITTED] TP16AU04.012


[[Page 50468]]


[GRAPHIC] [TIFF OMITTED] TP16AU04.013

    We believe the payment rates in Table 14 for several of the 
procedures that we are proposing to move out of new technology APCs and 
into clinical APCs require further explanation for a fuller 
understanding.
    For CPT code 96567, (Photodynamic therapy of the skin), the impact 
of the estimated payment decrease between CY 2004 and CY 2005 is 
actually low as the CY 2004 payment included the topically applied drug 
required to perform this procedure and the CY 2005 estimated payment 
does not. We now are proposing to pay separately for the drug billed 
under code J7308 in CY 2005. We have adequate claims data on which to 
base payment for that procedure in a clinically appropriate APC. 
Payment based on those data in addition to removal of the drug for 
separate payment resulted in a lower median for the APC.
    In the case of CPT code 33224, (Insertion of a left ventricular 
pacing lead and connection), based on a comparison of payment rates for 
CY 2004 and the estimated rate for CY 2005, it appears that there is a 
large increase in payment that results from reassigning the code from 
its new technology APC to a clinical APC. The difference is due to the 
fact that the estimated CY 2005 APC payment includes the cost of the 
left ventricular lead that was not included in the CY 2004 new 
technology APC payment. That left ventricular lead was paid as a pass-
through device under code C1900 in CY 2004, but is no longer eligible 
for pass-through payments in CY 2005, and, as such, is now included in 
the APC for the procedure.
    Similarly, the CY 2005 estimated payment for CPT code 33225, (Left 
ventricular pacing lead add-on), includes the cost of the ventricular 
lead. However, for 33225, the data are still somewhat unstable. 
Therefore, we are proposing to maintain that procedure in a new 
technology APC, but at a higher payment level, reflecting the 
additional cost of the lead.
    We note that a number of positron emission tomography (PET) scans 
currently are classified into New Technology APC 1516. We recognize 
that PET is an important technology in many instances and want to 
ensure that the technology remains available to Medicare beneficiaries 
when medically necessary. We believe that we have sufficient data to 
assign PET scans to a clinically appropriate APC. We have been told, 
however, that if the effect of doing so is to reduce payment for the 
procedure, it may hinder access to this technology. Therefore, we are 
considering three options as the proposed payment for these procedures 
in CY 2005, based on our review of the 2003 claims data for the PET 
procedures, and we specifically invite comments on each of these 
options.
    Option 1: Continue in CY 2005 the current assignment of the scans 
to New Technology APC 1516 prior to assigning to a clinical APC.
    Option 2: Assign the PET scans to a clinically appropriate APC 
priced according to the median cost of the scans based on CY 2003 
claims data. Under this option, we would assign PET scans to APC 0420, 
PET imaging.
    Option 3: Transition assignment to a clinical APC in CY 2006 by 
setting payment in CY 2005 based on a 50-50 blend of the median cost 
and the CY 2004 New Technology. We would assign the scans to New 
Technology APC 1513 for a blended transition payment. The rates for 
these options are in addendum B.

G. Proposed Changes to the Inpatient List

[If you choose to comment on issues in this section, please indicate 
the caption ``Inpatient List'' at the beginning of your comment.]
    We advised the APC Panel of a request that we had received to move 
four codes for percutaneous abscess drainage 44901(Drain append. 
abscess, percutaneous), 49021 (Drain abdominal abscess), 49041 (Drain 
percutaneous abdominal abscess), 49061(Drain, percutaneous, retroper. 
abscess)) from the inpatient list and to assign them to appropriate 
APCs. The APC Panel also recommended that we evaluate other codes on 
the inpatient list for possible APC assignment and that we consider 
eliminating the inpatient list.
    We are proposing to remove the four above-cited codes and assign 
them to clinically appropriate APCs, as recommended by the APC Panel. 
We are proposing to assign code 44901 to APC 0037, code 49021 to APC 
0037; code 49041 to APC 0037; and code 49061 to APC 0037. We discuss in 
section VII.E. of this preamble our response to the APC Panel's 
recommendation that we either abolish the inpatient list or evaluate it 
for any appropriate changes.

H. Proposed Assignment of ``Unlisted'' HCPCS Codes

[If you choose to comment on issues in this section, please indicate 
the caption

[[Page 50469]]

``Unlisted HCPCS Codes'' at the beginning of your comment.]
1. Background
    Some HCPCS codes are used to report services that do not have 
descriptors that define the exact service furnished. They are commonly 
called ``unlisted'' codes. The code descriptors often contain phrases 
such as: ``unlisted procedure'', ``not otherwise classified,'' or ``not 
otherwise specified.'' The unlisted codes typically fall within a 
clinical or procedural category, but they lack the specificity needed 
to describe the resources used in the service. For example, CPT code 
17999 is defined as, ``Unlisted procedure, skin, mucous membrane and 
subcutaneous tissue.'' The unlisted codes provide a way for providers 
to report services for which there is no HCPCS code that specifically 
describes the service furnished. However, the lack of specificity in 
describing the service prevents us from assigning the code to an APC 
based on clinical homogeneity and median cost.
    In most cases, the unlisted codes are assigned to the lowest level, 
clinically appropriate APC under the Medicare OPPS. This creates an 
incentive for providers to select the appropriate, specific HCPCS code 
to describe the service where one is available. In addition, if there 
is no HCPCS code that accurately describes the service, placing the 
unlisted code in the lowest level APC provides an incentive for 
interested parties to secure a code through the AMA's CPT process that 
will describe the service. Once a code that accurately describes the 
service is created, we can collect data on the service and place it in 
the correct APC based on the clinical nature of the service and its 
median cost.
    We do not use the median cost for the unlisted codes in the 
establishment of the weight for the APC to which the code is assigned 
because, by definition of the code, we do not know what service or 
combination of services is reflected in the claims billed using the 
unlisted code.
    Our review of HCPCS code assignments to APCs has revealed that 
there are a number of unlisted codes that are not assigned to the 
lowest level APC.
2. Proposal for CY 2005
    We are proposing to reassign these unlisted codes for CY 2005 OPPS 
to the lowest level APC in the clinical grouping in which the unlisted 
code is located. The list of those codes, the current APC assignment, 
and the assignment we propose for CY 2005 OPPS are displayed in Table 
15.
    We continue to believe that assigning unlisted codes to the lowest 
level of the APC for the clinical or procedural grouping into which the 
code falls creates an appropriate incentive for providers to pursue 
assignment of new codes where they are needed. Moreover, payment at the 
lowest level of APC for the clinical or procedural grouping allows for 
some payment for the services furnished and also ensures that we do not 
pay inappropriately for services that are unspecified.

I. Proposed Addition of New Procedure Codes

    During the first two quarters of CY 2004, we created 85 HCPCS codes 
that were not addressed in the November 7, 2003 final rule that updated 
the CY 2004 OPPS. We have designated the payment status of those codes, 
which are shown in Table 16 below, and added them to the April and July 
updates of the 2004 OPPS (Transmittals 3144, 3154, 3322, and 3324). 
Thirty of the new codes were created to enable providers to bill for 
brand name drugs and to receive payments at a rate that differs from 
that for generic equivalents, as mandated in new section 
1833(t)(14)(A)(i) of the Act as added by Pub. L. 108-173. In this 
proposed rule, we are soliciting comment on the APC assignment of these 
services. Further, consistent with our annual APC updating policy, we 
are proposing to assign the new HCPCS codes for CY 2005 to the 
appropriate APCs and would incorporate them into our final rule for CY 
2005.

J. Proposed OPPS Changes: Provisions of MMA (Pub. L. 108-173)

1. Payment for Initial Preventive Physical Examinations (Section 611 of 
Pub. L. 108-173)
[If you choose to comment on issues in this section, please indicate 
the caption ``Physical Examinations'' at the beginning of your 
comment.]
a. Background
    Section 611 of Pub. 108-173 provides for coverage under Medicare 
Part B of an initial preventive physical examination for new 
beneficiaries, effective for services furnished on or after January 1, 
2005. This provision applies to beneficiaries whose coverage period 
under Medicare Part B begins on or after January 1, 2005, and only for 
an initial preventive physical examination performed within 6 months of 
the beneficiary's initial coverage date.
    Current Medicare coverage policy does not allow for payment for 
routine physical examinations (or checkups) that are furnished to 
beneficiaries. Before the enactment of Pub. L. 108-173, all preventive 
physical examinations had been excluded from coverage based on section 
1862(a)(7) of the Act, which states that routine physical checkups are 
excluded services. This exclusion is specified in regulations under 
Sec.  411.15(a). In addition, preventive physical examinations had been 
excluded from coverage based on section 1862(a)(1)(A) of the Act. This 
section of the Act provides that items and services must be reasonable 
and necessary for the diagnosis or treatment of illness or injury or to 
improve the functioning of a malformed body member (as implemented in 
regulations under Sec.  411.15(k)).
    Coverage of initial preventive physical examinations is provided 
only under Medicare Part B. As provided in the statute, this new 
coverage allows payment for one initial preventive physical examination 
within the first 6 months after the beneficiary's first Part B coverage 
begins, although that coverage period may not begin before January 1, 
2005. We also note that Pub. L. 108-173 did not make any provision for 
the waiver of the Medicare coinsurance and Part B deductible for the 
initial preventive physical examination. Payment for this service would 
be applied to the required Medicare Part B deductible, which is $110 
for CY 2005, if the deductible has not been met, and the usual 
coinsurance provisions would apply.
b. Proposed Amendments to Regulations
    We are proposing to amend our regulations to add a new Sec.  410.16 
that would provide for coverage of initial preventive physical 
examinations in various settings, including the hospital outpatient 
department, as specified in the statute, and specify the condition for 
coverage and limitation on coverage. In addition, we are proposing to 
conform our regulations on exclusions from coverage under Sec.  
411.15(a)(1) and Sec.  411.15(k) to the provisions of section 611 of 
Pub. L. 108-173. Specifically, we are proposing to specify an exception 
to the list of examples of routine physical checkups that are excluded 
from coverage under Sec.  411.15(a) and to add a new exclusion under 
Sec.  411.15(k)(11).
    We are proposing to amend Sec.  419.21 of the OPPS regulations to 
add a new paragraph (e) to specify payment for an initial preventive 
physical examination as a Medicare Part B covered service under the 
OPPS if the examination is furnished within the first 6 months of the 
beneficiary's first Medicare Part B coverage.
    We note that the initial preventive physical examination is also 
addressed in detail in our proposed rule to update the Medicare 
Physician's Fee Schedule for CY 2005. However, because we believe the 
same elements of the initial physical examination furnished in a 
physician's office would also apply when the examination is performed 
in a hospital outpatient clinic, we are proposing to revise the 
applicable regulations to reflect this requirement.
    Section of 611(b) of Pub. L. 1089-173 define an ``initial 
preventive physical examination'' to mean physicians'' services 
consisting of--
    (1) A physical examination (including measurement of height, 
weight, blood pressure, and an electrocardiogram, but excluding 
clinical laboratory tests) with the goal of health promotion and 
disease detection; and
    (2) Education, counseling, and referral with respect to screening 
and other preventive coverage benefits separately authorized under 
Medicare Part B, excluding clinical lab tests.
    Specifically, section 611(b) of Pub. L. 108-173 provides that the 
education, counseling, and referral services with respect to the 
screening and other preventive services authorized under Medicare Part 
B include the following:
    (1) Pneumococcal, influenza, and hepatitis B vaccine and their 
administration;
    (2) Screening mammography;
    (3) Screening pap smear and screening pap smear and screening 
pelvic examination;
    (4) Prostate cancer screening tests;
    (5) Colorectal cancer screening tests;
    (6) Diabetes outpatient self-management training services;
    (7) Bone mass measurements;
    (8) Screening for glaucoma;
    (9) Medical nutrition therapy services for individuals with 
diabetes and renal disease;
    (10) Cardiovascular screening blood tests; and
    (11) Diabetes screening tests.
    Section 611(d)(2) of Pub. L 108-173 amended section 
1861(s)(2)(K)(i) and (ii) of the Act to specify the services identified 
as physicians' services and referred to in the definition of initial 
preventive physical examination include services furnished by a 
physician assistant, a nurse practitioner, or a clinical nurse 
specialist. We refer to these professionals as ``qualified nonphysician 
practitioners.''
    Based on the language of the statute, our review of the medical 
literature, current clinical practice guidelines, and United States 
Preventive Services Task Force recommendations, we are proposing (under 
proposed new Sec.  410.16(a), Definitions) to interpret the term 
``initial preventive physical examination'' for purposes of this new 
benefit to include all of the following services furnished by a doctor 
of medicine or osteopathy or a qualified nonphysician practitioner:
    (1) Review of the individual's comprehensive medical and social 
history. We are proposing to define ``medical history'' to include, as 
a minimum, past medical and surgical history, including experience with 
illnesses, hospital stays, operations, allergies, injuries, and 
treatments; current medications and supplements, including calcium and 
vitamins; and family history, including a review of medical events in 
the patient's family, including diseases that may be hereditary or 
place the individual at risk. We are proposing to define ``social 
history'' to include, at a minimum, history of alcohol, tobacco, and 
illicit drug use; work and travel history; diet; social activities; and 
physical activities.
    (2) Review of the individual's potential (risk factors) for 
depression (including past experiences with depression or other mood 
disorders) based on the use of an appropriate screening instrument that 
the physician or other qualified nonphysician practitioner may select 
from various available standardized screening tests for this purpose, 
unless the appropriate screening instrument is defined through the 
national coverage determination (NCD) process.

[[Page 50473]]

    (3) Review of the individual's functional ability and level of 
safety (that is, at a minimum, a review of the following areas: hearing 
impairment, activities of daily living, falls risk, and home safety), 
based on the use of an appropriate screening instrument, which the 
physician or other qualified nonphysician practitioner may select from 
various available standardized screening tests for this purpose, unless 
the appropriate screening instrument is further defined through the NCD 
process.
    (4) An examination to include measurement of the individual's 
height, weight, blood pressure, a visual acuity screen, and other 
factors as deemed appropriate, based on the individual's comprehensive 
medical and social history and current clinical standards.
    (5) Performance of an electrocardiogram and interpretation.
    (6) Education, counseling, and referral, as deemed appropriate, 
based on the results of elements (1) through (5) of the proposed 
definition of the initial preventive physical examination.
    (7) Education, counseling, and referral, including a written plan 
for obtaining the appropriate screening and other preventive services, 
which are also covered as separate Medicare Part B benefits; that is, 
pnuemococcal, influenza, and hepatitis B vaccines and their 
administration, screening mammography, screening pap smear and 
screening pelvic exams, prostate cancer screening tests, diabetes 
outpatient self-management training services, bone mass measurements, 
screening for glaucoma, medical nutrition therapy services, 
cardiovascular screening blood tests, and diabetes screening tests.
    In view of the possibility that it may be appropriate to include 
other (or revised) elements in the definition of the term ``initial 
preventive physical examination,'' we are requesting public comments on 
this issue. For example, we have chosen not to define the term 
``appropriate screening instrument'' for screening individuals for 
depression, alcohol, tobacco and illicit drug use, functional ability, 
and level of safety because we anticipate that the examining physician 
or qualified nonphysician practitioner would want to use the test of 
his or her choice, based on current clinical practice guidelines. We 
believe that any standardized screening test for depression, substance 
abuse, functional ability, and level of safety recognized by the 
American Academy of Family Physicians, the American College of 
Physicians-American Society of Internal Medical, the American College 
of Preventive Medicine, the American Geriatrics Society, the American 
Psychiatric Association, and the United States Preventive Services Task 
Force would be acceptable for purposes of meeting the ``appropriate 
screening instrument'' provision.
    To facilitate our future consideration of defining more 
specifically the type or types of appropriate screening instruments for 
depression, substance abuse, functional ability, or level of safety, we 
are proposing to include provisions in paragraphs (2) and (3) under the 
proposed definition of initial preventive physical examination that 
would allow us to do this through the NCD process. This proposed 
approach would allow us to conduct a more timely assessment of new 
types of screening tests than would be possible under the standard 
rulemaking process. We intend to use the NCD process, if necessary, for 
evaluating appropriate new screening tests for depression; alcohol, 
tobacco and illicit drug use; functional ability; or level of safety. 
This NCD process includes an opportunity for public comment in order to 
evaluate the medical and scientific issues related to the coverage of 
the new tests that may be brought to our attention in the future.
c. Proposed Assignment of New HCPCS Code for Payment of Initial 
Preventive Physical Examinations
    There is no current CPT code that contains the specific elements 
included in the initial preventive physical examination. Therefore, we 
are proposing to establish the following new HCPCS code, GXXXX, Initial 
preventive physical examination, to be used to bill for the new service 
under both the Medicare physician fee schedule and the OPPS. As 
required by the statute, this code includes an electrocardiogram, but 
does not include the other previously mentioned preventive services 
that are currently separately covered and paid under the Medicare Part 
B screening benefits. When these other preventive services are 
performed, they should be identified using the existing appropriate 
codes.
    For payment under the physician fee schedule, relative value units 
are being proposed for new HCPCS code GXXXX based on equivalent 
resources and work intensity to those contained in CPT E/M code 99203 
(new patient, office or other outpatient visit) and CPT 93000 
(electrocardiogram, complete). The ``technical component'' is the 
portion of the physician fee schedule that is most comparable to what 
Medicare pays under the OPPS, the costs other than the physician 
professional services that are billed and paid for separately under the 
fee schedule, not OPPS. The estimated technical component of the 
physician fee schedule is between $50 and $100.
    Given our lack of cost data to guide assignment of the new benefit 
into a clinically appropriate APC, we are proposing to assign GXXXX to 
the new technology APC 1539 that has a payment level of $50 to $100. 
Temporary assignment to a new technology APC allows us to pay for the 
new benefit provided in the OPD while we accrue claims data and 
experience on which to base a clinically relevant APC assignment.
d. Handling of Comments Received in Response to This Proposal
    We will respond to all comments regarding the proposed elements 
required for the initial preventive physical examination, whether the 
examination is performed in a physician's office or clinic or in a 
hospital clinic, in the final rule implementing the Medicare Physician 
Fee Schedule for CY 2005. We will respond to comments regarding payment 
for the examination under the OPPS in the subsequent final rule 
implementing the OPPS payment rates for CY 2005.
2. Payment for Certain Mammography Services (Section 614 of Pub. L. 
108-173)
[If you choose to comment on issues in this section, please indicate 
the caption ``Mammography'' at the beginning of your comment.]
    Section 614 of Pub. L. 108-173 amended section 1833(t)(1)(B)(iv) of 
the Act to provide that screening mammography and diagnostic 
mammography services are excluded from payment under the OPPS. This 
amendment applies to screening mammography services furnished on or 
after December 8, 2003 (the date of the enactment of Pub. L. 108-173), 
and in the case of diagnostic mammography, to services furnished on or 
after January 1, 2005. As a result of this amendment, both screening 
mammography and diagnostic mammography will be paid under the physician 
fee schedule.
    We are proposing to amend Sec.  419.22 of the regulations by adding 
a new paragraph(s) to specify that both screening mammography and 
diagnostic mammography will be excluded from payment under the OPPS, in 
accordance with section 614 of Pub. L. 108-173.

III. Proposed Recalibration of APC Relative Weights for CY 2005

[If you choose to comment on issues in this section, please include the 
caption

[[Page 50474]]

``APC Relative Weights'' at the beginning of your comment.]

A. Database Construction

    Section 1833(t)(9)(A) of the Act requires that the Secretary review 
and revise the relative payment weights for APCs at least annually, 
beginning in CY 2001 for application in CY 2002. In the April 7, 2000 
final rule (65 FR 18482), we explained in detail how we calculated the 
relative payment weights that were implemented on August 1, 2000 for 
each APC group. Except for some reweighting due to APC changes, these 
relative weights continued to be in effect for CY 2001. (See the 
November 13, 2000 interim final rule (65 FR 67824 through 67827).)
    To recalibrate the relative APC weights for services furnished on 
or after January 1, 2005, and before January 1, 2006, we are proposing 
to use the same basic methodology that we described in the April 7, 
2000 final rule. That is, we would recalibrate the weights based on 
claims and cost report data for outpatient services. We are proposing 
to use the most recent available data to construct the database for 
calculating APC group weights. For the purpose of recalibrating APC 
relative weights for CY 2005, the most recent available claims data are 
the approximately 119 million final action claims for hospital OPD 
services furnished on or after January 1, 2003, and before January 1, 
2004.
    Of the 119 million final action claims for OPPS services, 96.7 
million claims were of the type of bill potentially appropriate for use 
in setting rates for OPPS services (but did not necessarily contain 
services payable under OPPS). Of the 96.7 million claims, we were able 
to use 48.5 million whole claims (from which we created 75 million 
single procedure claim records) to set OPPS proposed for CY 2005 
weights.
    The proposed weights and payments in Addenda A and B to this 
proposed rule were calculated using claims from this period that had 
been processed before January 1, 2004. We selected claims for services 
paid under the OPPS and matched these claims to the most recent cost 
report filed by the individual hospitals represented in our claims 
data. We are proposing that the APC relative weights for CY 2005 under 
the OPPS would continue to be based on the median hospital costs for 
services in the APC groups. For the final rule, we are proposing to 
base median costs on claims for services furnished in CY 2003 and 
processed before June 30, 2004.
1. Proposed Treatment of Multiple Procedure Claims
    For CY 2005, we are proposing to continue to use single procedure 
claims to set the medians on which the weights would be based. We have 
received many requests that we ensure that the data from claims that 
contain charges for multiple procedures are included in the data from 
which we calculate the CY 2005 relative payment weights. Requesters 
believe that relying solely on single procedure claims to recalibrate 
APC weights fails to take into account data for many frequently 
performed procedures, particularly those commonly performed in 
combination with other procedures. They believe that, by depending upon 
single procedure claims, we base payment weights on the least costly 
services, thereby introducing downward bias to the medians on which the 
weights are based.
    We agree that, optimally, it is desirable to use the data from as 
many claims as possible to recalibrate the relative payment weights, 
including those with multiple procedures. As discussed in the 
explanation of single procedure claims below, we have used the date of 
service on the claims and a list of codes to be bypassed to create 
``pseudo'' single claims from multiple procedure claims. We refer to 
these newly created single procedure claims as ``pseudo'' singles 
because they were submitted by providers as multiple procedure claims.
2. Proposed Use of Single Procedure Claims
    We use single procedure claims to set the median costs for APCs 
because we are, so far, unable to ensure that packaged costs can be 
correctly allocated across multiple procedures performed on the same 
date of service. However, bypassing specified codes that we believe do 
not have significant packaged costs enables use of more data from 
multiple procedure claims. For CY 2003, we created ``pseudo'' single 
claims by bypassing HCPCS codes 93005 (Electrocardiogram, tracing), 
71010 (Chest x-ray), and 71020 (Chest x-ray) on a submitted claim. 
However, we did not use claims data for the bypassed codes in the 
creation of the median costs for the APCs to which these three codes 
were assigned because the level of packaging that would have remained 
on the claim after we selected the bypass code was not apparent and 
therefore, it was difficult to determine if the medians for these codes 
would be correct.
    For CY 2004, we created ``pseudo'' single claims by bypassing these 
three codes and also by bypassing an additional 269 HCPCS codes in 
APCs. These codes were selected by CMS based on a clinical review of 
the services and because it was presumed that these codes had only very 
limited packaging and could appropriately be bypassed for the purpose 
of creating ``pseudo'' single claims. The APCs to which these codes 
were assigned were varied and included mammography, cardiac 
rehabilitation, and level I plain film x-rays. To derive more 
``pseudo'' single claims, we also broke claims apart where there were 
dates of service for revenue code charges on that claim that could be 
matched to a single procedure code on the claim on the same date.
    As in CY 2003, we did not include the claims data for the bypassed 
codes in the creation of the APCs to which the 269 codes were assigned 
because, again, we had not established that such an approach was 
appropriate and would aid in accurately estimating the median cost for 
that APC. For CY 2004, from about 16.3 million otherwise unusable 
claims, we were able to use about 9.5 million multiple procedure claims 
to create about 27 million ``pseudo'' single claims. For CY 2005, from 
about 21 million otherwise unusable claims, we were able to use about 
18 million multiple procedure claims to create about 45.5 million 
``pseudo'' single claims.
    For CY 2005, we are proposing to continue using date of service 
matching as a tool for creation of ``pseudo'' single claims and also to 
take a more empirical approach to creating the list of codes that we 
would bypass to create ``pseudo'' single claims. The process we are 
proposing for CY 2005 OPPS results in our being able to use some part 
of 93 percent of the total claims eligible for use in OPPS ratesetting 
and modeling. In CY 2004, we were able to use some part of the data 
from 82 percent of eligible claims. This process enabled us to use 75 
million single bills for ratesetting: 45.5 million ``pseudo'' singles 
and 30.5 million ``natural'' single bills.
    We are proposing to bypass the 383 codes identified in Table 17 to 
create new single claims and to use the line-item costs associated with 
the bypass codes on these claims in the creation of the median costs 
for the APCs into which they are assigned. Of the codes on this list, 
only 123 (32 percent) were used for bypass in CY 2004.
    We developed the proposed bypass list using four criteria:

[[Page 50475]]

    a. We developed the following empirical standards by reviewing the 
frequency and magnitude of packaging in the single claims for payable 
codes other than drugs and biologicals. We assumed that the 
representation of packaging on the single claims for any given code is 
comparable to packaging for that code in the multiple claims.
     There were 100 or more single claims for the code. This 
ensured that observed outcomes were sufficiently representative of 
packaging that might occur in the multiple claims.
     Five percent or fewer of the single claims for the code 
had packaged costs on that single claim for the code. This criterion 
results in limiting the amount of packaging being redistributed to the 
payable procedure remaining on the claim after the bypass code is 
removed and ensures that the costs associated with the bypass code 
represent the cost of the bypassed service. For the remaining payable 
codes, the average percentage of single claims with any packaged costs 
was 70 percent, and the chosen threshold of 5 percent fell at roughly 
the 15th percentile.
     The median cost of packaging observed in the single claim 
was equal to or less than $50. This limits the amount of error in 
redistributed costs.
     The code is not a code for an unlisted service.
    b. We examined APCs relying on a low volume of single claims, and 
it became apparent that several radiological supervision and 
interpretation codes were commonly billed with the procedural codes in 
the APCs. We then reviewed all radiological supervision and 
interpretation codes to assess their viability as bypass codes. For the 
codes included on the list in Table 17, we determined that, generally, 
the packaging on claims, including these radiological supervision and 
interpretation codes, should be associated with the procedure 
performed.
    c. We examined radiation planning and related codes provided by a 
professional organization. In the organization's opinion, the codes 
could safely be bypassed and used without packaging to set medians for 
the APCs into which these codes are assigned. Many of the codes the 
organization recommended met our criterion under item a., and the 
remaining codes were close. Therefore, after reviewing such codes, we 
are proposing to adopt as bypass codes all radiation planning and 
related codes as provided by the organization.
    d. We included HCPCS codes 93005 and 71010. These codes have been 
bypassed for the past 3 years and generate a significant amount of new 
single claims because they are very commonly done on the same date of 
surgery. They have low median packaged costs and a low percentage of 
single claims with any packaged costs, 6 percent and 18 percent, 
respectively.
    We invite public comment on the ``pseudo'' single process, 
including the bypass list and the criteria.

    However, we note several inherent features of multiple bill claims 
that prevented us from the further creation of ``pseudo'' singles. We 
discussed these obstacles in detail in the August 9, 2002 proposed rule 
(67 FR 52092, 52108 through 52111) and the November 1, 2001 final rule 
(66 FR 66718 and 66743 through 66746).
    Notwithstanding the obstacles in creating additional ``pseudo'' 
single claims, we have received a number of suggestions from outside 
sources providing options to this approach. Some of the suggestions 
involved complex methodologies driven by lengthy tables of codes and 
complex logic that focused on creating ``pseudo'' singles by packaging 
specific packaged HCPCS codes with specific payable HCPCS codes. While 
we appreciate the time and attention spent by various parties 
interested in this issue, our review of the suggestions and our 
empirical analysis of the most specific and detailed recommendation 
using the data used to develop the APC relative weights for the APC 
Panel's February 2004 meeting indicated that code-specific packaging 
would add a significant amount of time and complexity to the 
ratesetting process and would require involved annual maintenance to 
accurately update the code sets used in the suggested methodology each 
year. Moreover, we would experience only a modest increase in 
``pseudo'' single claims.
    Further, code-specific packaging does not appear to appreciably 
increase the volume of single bills available for calculating medians 
for those APCs that are currently derived from a small volume of total 
claims. We believe that the observed modest improvements in the 
``pseudo'' single claims volume from code-specific packaging can be 
attributed to the number and variety of services billed on multiple 
procedure claims, which often have complex HCPCS code combinations. 
These complex claims cannot be reduced to single bills by packaging the 
costs for a few procedures. In light of these findings, we are not 
proposing to adopt any code-specific packaging proposals. However, we 
would review and consider any other specific proposals that we received 
as comments.
    Other suggestions included recommendations that the costs in 
packaged revenue codes and packaged HCPCS codes be allocated separately 
to paid HCPCS codes based on the prior year's payment weights or 
payment rates for the single procedures. Still other suggestions 
recommended that we allocate the packaged costs in proportion to the 
charges or to the costs for the major procedures based on the current 
year's claims. We are concerned that using a prior year's median costs, 
relative weights or payment rates as the basis to allocate current 
year's packaged costs to current year costs for payable HCPCS codes may 
not be appropriate. For example, if two procedures are performed and 
one uses an expensive device, this methodology would split the costs of 
the device between the service that uses the device and a service that 
does not use the device, thus resulting in incorrect allocation of the 
packaged costs. Therefore, we are not proposing to incorporate these 
suggestions in our ratesetting methodology but we intend to examine 
them more thoroughly.
    We continue to seek strategies that would enable us to use more 
multiple procedure claims and continue to explore whether there are 
techniques that could result in medians that are more representative of 
the relative cost of the services being furnished. However, at this 
time, we are not proposing a methodology beyond use of dates of service 
and the expanded bypass list. We solicit specific proposals provided in 
comments on how multiple procedure claims can be better used in 
calculating the relative payment weights.

B. Proposed Calculation of Median Costs for CY 2005

    In this section of the preamble, we discuss the use of claims to 
calculate the proposed OPPS payment rates for CY 2005. (See the 
hospital outpatient prospective payment page on the CMS website on 
which this proposed rule is posted for an accounting of claims used in 
the development of the proposed rates: http://www.cms.hhs.gov/hopps.) The 

accounting of claims used in the development of the proposed rule is 
included under supplemental materials for this proposed rule. That 
accounting provides additional detail regarding the number of claims 
derived at each stage of the process. In addition, we note that below 
we discuss the files of claims that comprise the data sets that are 
available for purchase under a CMS data user contract. See 
http://www.cms.hhs.gov/providers/hopps for information about purchasing the 

following two OPPS data files: ``OPPS limited data set'' and ``OPPS 
identifiable data set''.
    We are proposing to use the following methodology to establish the 
weights to be used to set payment rates for CY 2005:
    We are proposing to use outpatient claims for full CY 2003 to set 
the weights for CY 2005. To begin the calculation of the weights for 
this proposed rule for CY 2005, we pulled all claims for outpatient 
services furnished in CY 2003 from the national claims history file. 
This is not the population of claims paid under the OPPS, but all 
outpatient claims (for example, ambulatory surgical center (ASC) claims 
reported on bill type 83, critical access hospital (CAH) claims, and 
hospital claims for clinical laboratory services for persons who are 
neither inpatients nor outpatients of the hospital).
    We then excluded claims with condition code 04, 20, 21, 77. These 
are claims that providers submitted to Medicare knowing that no payment 
will be made. For example, providers submit claims with a condition 
code 21 to elicit

[[Page 50487]]

an official denial notice from Medicare and document that a service is 
not covered. We then excluded claims for services furnished in 
Maryland, Guam, and the U.S. Virgin Islands because hospitals in those 
geographic areas are not paid under the OPPS.
    We divided the remaining claims into three groups shown below. 
Groups 2 and 3 comprise the 96.7 million claims that contain hospital 
bill types paid under the OPPS.
    1. Claims that were not bill types 12X, 13X, 14X (hospital bill 
types) or 76X (CMHC bill types). Other bill types, such as ASCs, bill 
type 83, are not paid under the OPPS and, therefore, these claims were 
not used to set OPPS payment.
    2. Bill types 12X, 13X, or 14X (hospital bill types). These claims 
are hospital outpatient claims.
    3. Bill type 76X (CMHC). (These claims are later combined with any 
claims in item 2 above with a condition code 41 to set the per diem 
partial hospitalization rate determined through a separate process.)
    In previous years, we have begun the CCR calculation process using 
the most recent available cost reports for all hospitals irrespective 
of whether any or all of the hospitals included actually filed hospital 
outpatient claims for the data period. However, for this proposed rule, 
we first limited the population of cost reports to only those for 
hospitals that filed outpatient claims in CY 2003 before determining 
whether the CCRs for such hospitals were valid. This initial limitation 
changed the distribution of CCRs used during the trimming process 
discussed below.
    We then calculated the cost-to-charge ratios (CCRs) at a 
departmental level and overall for each hospital for which we had 
claims data. We did this using hospital specific data from the Hospital 
Cost Report Information System (HCRIS). We used the most recent 
available cost report data, in most cases, cost reports for CY 2001 or 
CY 2002. We used the most recent available cost report, whether 
submitted or settled. If the most recent available cost report was 
submitted but not settled, we looked at the last settled cost report to 
determine the ratio of submitted to settled cost and we then adjusted 
the most recent available submitted but not settled cost report using 
that ratio. We are proposing to use these same CCRs ratios for the 
final rule.
    We then flagged CAHs, which are not paid under the OPPS, and 
hospitals with invalid CCRs. These included claims from hospitals 
without a CCR, for hospitals paid an all-inclusive rate, for hospitals 
with obviously erroneous CCRs (greater than 90 or less than .0001), and 
for hospitals with CCRs that were identified as outliers (3 standard 
deviations from the geometric mean after removing error CCRs). In 
addition, we trimmed the CCRs at the departmental level by removing the 
CCRs for each cost center as outliers if they exceeded 3 
standard deviations of the geometric mean. We are proposing to use 
these trimmed CCRs for the final rule. In prior years, we did not trim 
CCRs at the departmental level. However, for CY 2005, we are proposing 
to trim at the departmental CCR level to eliminate aberrant CCRs that, 
if found in high volume hospitals, could skew the medians. We used a 
four-tiered hierarchy of cost center CCRs to match a cost center to a 
revenue code with the top tier being the most common cost center and 
the last tier being the default CCR. If a hospital's departmental CCR 
was deleted by trimming, we set the departmental CCR for that cost 
center to ``missing,'' so that another departmental CCR in the revenue 
center hierarchy could apply. If no other departmental CCR could apply 
to the revenue code on the claim, we used the hospital's overall CCR 
for the revenue code in question.
    We then converted the charges on the claim by applying the CCR that 
we believed was best suited to the revenue code indicated on the line 
with the charge. See Table 18 for the allowed revenue codes. Revenue 
codes not on this list are those not allowed under the OPPS because 
their services cannot be paid under the OPPS (for example, inpatient 
room and board charges) and, thus, charges with those revenue codes 
were not packaged for creation of the OPPS median costs. If a hospital 
did not have a CCR that was appropriate to the revenue code reported 
for a line item charge (for example, a visit reported under the clinic 
revenue code but the hospital did not have a clinic cost center), we 
applied the hospital-specific overall CCR, except as discussed in 
section V.H. of this proposed rule for calculation of costs for blood.
    Thus, we applied CCRs as described above to claims with bill types 
12X, 13X, or 14X, excluding all claims from CAHs and hospitals in 
Maryland, Guam, or the U.S. Virgin Islands, and flagged hospitals with 
invalid CCRs. We excluded claims from all hospitals for which CCRs were 
flagged as invalid.
    We identified claims with condition code 41 as partial 
hospitalization services of CMHCs and removed them to another file. 
These claims were combined with the 76X claims identified previously to 
calculate the partial hospitalization per diem rate.
    We then excluded claims without a HCPCS code. We also removed 
claims for observation services to another file. We removed to another 
file claims that contain nothing but flu and pneumococcal pneumonia 
(virus) (``PPV'') vaccine. Influenza and PPV vaccines are paid at 
reasonable cost and, therefore, these claims are not used to set OPPS 
rates. We note that the two above mentioned separate files containing 
partial hospitalization claims and the observation services claims are 
included in the files that are available for purchase as discussed 
above.
    We next copied line item costs for drugs, blood, and devices (the 
lines stay on the claim but are copied off onto another file) to a 
separate file. No claims were deleted when we copied these lines onto 
another file. These line-items are used to calculate the per unit 
median for drugs, radiopharmaceuticals, and blood and blood products. 
The line-item costs were also used to calculate the per administration 
cost of drugs, radiopharmaceuticals, and biologicals (other than blood 
and blood products) for purposes of determining whether the cost of the 
item would be packaged or be paid separately. Section 1833(t)(16)(B) of 
the Act, as added by section 621(a)(2) of Pub. L. 108-173, requires the 
Secretary to lower to $50 the threshold for separate payment of drugs 
and biologicals and the per administration cost derived using these 
line-item cost data would be used to make that decision for CY 2005. As 
discussed in our November 7, 2003 final rule with comment period (68 FR 
63398), we had also applied a $50 threshold for the CY 2004 update to 
the OPPS.
    We then divided the remaining claims into five groups.
    1. Single Major Claims: Claims with a single separately payable 
procedure, all of which would be used in median setting.
    2. Multiple Major Claims: Claims with more than one separately 
payable procedure or multiple units for one payable procedure. As 
discussed below, some of these can be used in median setting.
    3. Single Minor Claims: Claims with a single HCPCS code that is not 
separately payable. These claims may have a single packaged procedure 
or a drug code.
    4. Multiple Minor Claims: Claims with multiple HCPCS codes that are 
not separately payable without examining dates of service. (For 
example, pathology codes are packaged unless they appear on a single 
bill by themselves. The multiple minor file has claims with multiple 
occurrences of pathology codes, with packaged costs

[[Page 50488]]

that cannot be appropriately allocated across the multiple pathology 
codes. However, by matching dates of service for the code and the 
reported costs through the ``pseudo'' single creation process discussed 
earlier, a claim with multiple pathology codes may become several 
``pseudo'' single claims with a unique pathology code and its 
associated costs on each day. These ``pseudo'' singles for the 
pathology codes would then be considered a separately payable code and 
would be used like claims in the single major claim file.
    5. Non-OPPS Claims: Claims that contain no services payable under 
the OPPS are excluded from the files used for the OPPS. Non-OPPS claims 
have codes paid under other fee schedules, for example, DME or clinical 
laboratory.
    We note that the claims listed in numbers 1 through 4 above are 
included in the data files that can be purchased as described above.
    We set aside the single minor claims and the non-OPPS claims 
(numbers 3 and 5 above) because we did not use either in calculating 
median cost.
    We then examined the multiple major and multiple minor claims 
(numbers 2 and 4 above) to determine if we could convert any of them to 
single major claims using the process described previously. We first 
grouped items on the claims by date of service. If each major procedure 
on the claim had a different date of service and if the line items for 
packaged HCPCS and packaged revenue codes had dates of service, we 
broke the claim into multiple ``pseudo'' single claims based on the 
date of service.
    After those single claims were created, we used a list of ``bypass 
codes'' to remove separately payable procedures that are thought to 
contain limited costs or no packaged costs from a multiple procedure 
bill. A discussion of the creation of the list of bypass codes used for 
the creation of ``pseudo'' single claims is contained in section 
III.A.2. of this preamble and the list of codes is provided in Table 
17.
    We excluded those claims that we were not able to convert to 
singles even after applying both of the techniques for creation of 
``pseudo'' singles. We then packaged the costs of packaged HCPCS (codes 
with status indicator ``N'' on Addendum B to this proposed rule) and 
packaged revenue codes (listed in Table 18) into the cost of the single 
major procedure remaining on the claim.
    After removing claims for hospitals with error CCRs, claims without 
HCPCS codes, claims for immunizations not covered under the OPPS, and 
claims for services not paid under the OPPS, 52.2 millions claims were 
left. This subset of claims is roughly one-half of the 96.7 million 
claims for bill types paid under the OPPS. Of these 52.2 million 
claims, we were able to use some portion of 48.5 million (93 percent) 
whole claims to create the 75 million single and ``pseudo'' single 
claims for use in our CY 2005 median payment ratesetting.

    We also excluded claims that either had zero costs after summing 
all costs on the claim or for which CMS lacked an appropriate provider 
wage index. For the remaining claims, we then wage adjusted 60 percent 
of the cost of the claim (which we determined to be the labor-related 
portion), as has been our policy since initial implementation of

[[Page 50490]]

the OPPS, to adjust for geographic variation in labor-related costs. We 
made this adjustment by determining the wage index that applied to the 
hospital that furnished the service and dividing the cost for the 
separately paid HCPCS code furnished by the hospital by that wage 
index. We used the pre-reclassified wage index proposed for IPPS 
published in the hospital IPPS proposed rule on May 18, 2004 (69 FR 
28196), and corrected in the IPPS correction notice published on June 
25, 2004 (69 FR 35919). These wage indices are reprinted i
