Medicare Program; Proposed Changes to the Hospital Inpatient 
Prospective Payment Systems and Fiscal Year 2005 Rates

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

ACTION: Proposed rule.

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

SUMMARY: We are proposing to revise the Medicare hospital inpatient 
prospective payment systems (IPPS) for operating and capital-related 
costs to implement changes arising from our continuing experience with 
these systems; and to implement a number of changes made by the 
Medicare Prescription Drug, Improvement, and Modernization Act of 2003 
(Pub. L. 108-173), enacted on December 8, 2003. In addition, in the 
Addendum to this proposed rule, we describe the proposed changes to the 
amounts and factors used to determine the rates for Medicare hospital 
inpatient services for operating costs and capital-related costs. These 
proposed changes would be applicable to discharges occurring on or 
after October 1, 2004. We also are setting forth proposed rate-of-
increase limits as well as proposed policy changes for hospitals and 
hospital units excluded from the IPPS that are paid on a reasonable 
cost basis subject to these limits.
    Among the policy changes that we are proposing to make are: Changes 
to the classification of cases to the diagnosis-related groups (DRGs); 
changes to the long-term care (LTC)-DRGs and relative weights; changes 
in the wage data, labor-related share of the wage index, and the 
geographic area designations used to compute the wage index; changes in 
the qualifying threshold criteria for and the proposed approval of new 
technologies and medical services for add-on payments; changes to the 
policies governing postacute care transfers; changes to payments to 
hospitals for the direct and indirect costs of graduate medical 
education; changes to the payment adjustment for disproportionate share 
rural hospitals; changes in requirements and payments to critical 
access hospitals (CAHs); changes to the disclosure of information 
requirements for Quality Improvement Organization (QIOs); and changes 
in the hospital conditions of participation for discharge planning and 
fire safety requirements for certain health care facilities.

I. Background

A. Summary

1. Acute Care Hospital Inpatient Prospective Payment System (IPPS)
    Section 1886(d) of the Social Security Act (the Act) sets forth a 
system of payment for the operating costs of acute care hospital 
inpatient stays under Medicare Part A (Hospital Insurance) based on 
prospectively set rates. Section 1886(g) of the Act requires the 
Secretary to pay for the capital-related costs of hospital inpatient 
stays under a prospective payment system (PPS). Under these PPSs, 
Medicare payment for hospital inpatient operating and capital-related 
costs is made at predetermined, specific rates for each hospital 
discharge. Discharges are classified according to a list of diagnosis-
related groups (DRGs).
    The base payment rate is comprised of a standardized amount that is 
divided into a labor-related share and a nonlabor-related share. The 
labor-related share is adjusted by the wage index applicable to the 
area where the hospital is located; and if the hospital is located in 
Alaska or Hawaii, the nonlabor-related share is adjusted by a cost-of-
living adjustment factor. This base payment rate is multiplied by the 
DRG relative weight.
    If the hospital treats a high percentage of low-income patients, it 
receives a percentage add-on payment applied to the DRG-adjusted base 
payment rate. This add-on payment, known as the disproportionate share 
hospital (DSH) adjustment, provides for a percentage increase in 
Medicare payments to hospitals that qualify under either of two 
statutory formulas designed to identify hospitals that serve a 
disproportionate share of low-income patients. For qualifying 
hospitals, the amount of this adjustment may vary based on the outcome 
of the statutory calculations.
    If the hospital is an approved teaching hospital, it receives a 
percentage add-on payment for each case paid under the IPPS (known as 
the indirect medical education (IME) adjustment). This percentage 
varies, depending on the ratio of residents to beds.
    Additional payments may be made for cases that involve new 
technologies or medical services that have been approved for special 
add-on payments. To qualify, a new technology or medical service must 
demonstrate that it is a substantial clinical improvement over 
technologies or services otherwise available, and that, absent an add-
on payment, it would be inadequately paid under the regular DRG 
payment.
    The costs incurred by the hospital for a case are evaluated to 
determine whether the hospital is eligible for an additional payment as 
an outlier case. This additional payment is designed to protect the 
hospital from large financial losses due to unusually expensive cases. 
Any outlier payment due is added to the DRG-adjusted base payment rate, 
plus any DSH, IME, and new technology or medical service add-on 
adjustments.
    Although payments to most hospitals under the IPPS are made on the 
basis of the standardized amounts, some categories of hospitals are 
paid the higher of a hospital-specific rate based on their costs in a 
base year (the higher of FY 1982, FY 1987, or FY 1996) or the IPPS rate 
based on the standardized amount. For example, sole community hospitals 
(SCHs) are the sole source of care in their areas, and Medicare-
dependent, small rural hospitals (MDHs) are a major source of care for 
Medicare beneficiaries in their areas. Both of these categories of 
hospitals are afforded this special payment protection in order to 
maintain access to services for beneficiaries (although MDHs receive 
only 50 percent of the difference between the IPPS rate and their 
hospital-specific rates if the hospital-specific rate is higher than 
the IPPS rate).
    Section 1886(g) of the Act requires the Secretary to pay for the 
capital-related costs of inpatient hospital services ``in accordance 
with a prospective payment system established by the Secretary.'' The 
basic methodology for determining capital prospective payments is set 
forth in our regulations at 42 CFR 412.308 and 412.312. Under the 
capital PPS, payments are adjusted by the same DRG for the case as they 
are under the operating IPPS. Similar adjustments are also made for IME 
and DSH as under the operating IPPS. In addition, hospitals may receive 
an outlier payment for those cases that have unusually high costs.
    The existing regulations governing payments to hospitals under the 
IPPS are located in 42 CFR Part 412, Subparts A through M.
2. Hospitals and Hospital Units Excluded From the IPPS
    Under section 1886(d)(1)(B) of the Act, as amended, certain 
specialty hospitals and hospital units are excluded from the IPPS. 
These hospitals and units are: psychiatric hospitals and units; 
rehabilitation hospitals and units; long-term care hospitals (LTCHs); 
children's hospitals; and cancer hospitals. Various sections of the 
Balanced Budget Act of 1997 (Pub. L. 105-33), the Medicare, Medicaid 
and SCHIP [State Children's Health Insurance Program] Balanced Budget 
Refinement Act of 1999 (Pub. L. 106-113), and the Medicare, Medicaid, 
and SCHIP Benefits Improvement and Protection Act of 2000 (Pub. L. 106-
554) provide for the implementation of PPSs for rehabilitation 
hospitals and units (referred to as inpatient rehabilitation facilities 
(IRFs)), psychiatric hospitals and units (referred to as inpatient 
psychiatric facilities (IPFs)), and LTCHs, as discussed below. 
Children's hospitals and cancer hospitals continue to be paid under 
reasonable cost-based reimbursement.
    The existing regulations governing payments to excluded hospitals 
and

[[Page 28201]]

hospital units are located in 42 CFR Parts 412 and 413.
a. IRFs
    Under section 1886(j) of the Act, as amended, rehabilitation 
hospitals and units (IRFs) have been transitioned from payment based on 
a blend of reasonable cost reimbursement subject to a hospital-specific 
annual limit under section 1886(b) of the Act and prospective payments 
for cost reporting periods beginning January 1, 2002 through September 
30, 2002, to payment on a full prospective payment system basis 
effective for cost reporting periods beginning on or after October 1, 
2002 (66 FR 41316, August 7, 2001; 67 FR 49982, August 1, 2002; and 68 
FR 45674, August 1, 2003). The existing regulations governing payments 
under the IRF PPS are located in 42 CFR Part 412, Subpart P.
b. LTCHs
    Under the authority of sections 123(a) and (c) of Public Law 106-
113 and section 307(b)(1) of Public Law 106-554, LTCHs are being 
transitioned from being paid for inpatient hospital services based on a 
blend of reasonable cost-based reimbursement under section 1886(b) of 
the Act to fully Federal prospective rates during a 5-year period, 
beginning with cost reporting periods that start on or after October 1, 
2002. For cost reporting periods beginning on or after October 1, 2006, 
LTCHs will be paid under the fully Federal prospective payment rate 
(the June 6, 2003 LTCH PPS final rule (68 FR 34122)). LTCHs may elect 
to be paid based on full PPS payments instead of a blended payment in 
any year during the 5-year transition period. The existing regulations 
governing payment under the LTCH PPS are located in 42 CFR part 412, 
Subpart O.
c. IPFs
    Sections 124(a) and (c) of Public Law 106-113 provide for the 
development of a per diem PPS for payment for inpatient hospital 
services furnished in IPFs under the Medicare program, effective for 
cost reporting periods beginning on or after October 1, 2002. This 
system must include an adequate patient classification system that 
reflects the differences in patient resource use and costs among these 
hospitals and maintains budget neutrality. We published a proposed rule 
to implement the PPS for IPFs on November 28, 2003 (68 FR 66920). The 
November 28, 2003 proposed rule proposed an April 1, 2004 effective 
date for purposes of ratesetting and calculating impacts. However, the 
proposed rule was unusually complex because it proposed a completely 
new payment system for inpatient hospital services furnished by 
psychiatric hospitals and units and the public requested additional 
time to comment. As a result, we extended the comment period for the 
proposed rule. Thus, we are still in the process of analyzing public 
comments and developing a final rule for publication. Consequently, an 
April 1, 2004 effective date for the IPF PPS is no longer possible.
3. Critical Access Hospitals (CAHs)
    Under sections 1814, 1820, and 1834(g) of the Act, payments are 
made to critical access hospitals (CAHs) (that is, rural hospitals or 
facilities that meet certain statutory requirements) for inpatient and 
outpatient services on a reasonable cost basis. Reasonable cost is 
determined under the provisions of section 1861(v)(1)(A) of the Act and 
existing regulations under 42 CFR Parts 413 and 415.
4. Payments for Graduate Medical Education (GME)
    Under section 1886(a)(4) of the Act, costs of approved educational 
activities are excluded from the operating costs of inpatient hospital 
services. Hospitals with approved graduate medical education (GME) 
programs are paid for the direct costs of GME in accordance with 
section 1886(h) of the Act; the amount of payment for direct GME costs 
for a cost reporting period is based on the hospital's number of 
residents in that period and the hospital's costs per resident in a 
base year. The existing regulations governing payments to the various 
types of hospitals are located in 42 CFR part 413.
    On August 1, 2003, we published a final rule in the Federal 
Register (68 FR 45346) that implemented changes to the Medicare 
hospital inpatient prospective payment systems for both operating cost 
and capital-related costs, as well as changes addressing payments for 
excluded hospitals and payments for GME costs. Generally these changes 
were effective for discharges occurring on or after October 1, 2003. On 
October 6, 2003, we published a document in the Federal Register (68 FR 
57731) that corrected technical errors made in the August 1, 2003 final 
rule.

B. 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), Public Law 108-173, was enacted. 
Public Law 108-173 made a number of changes to the Act relating to 
prospective payments to hospitals for inpatient services, payments to 
excluded hospitals and units, and payments to CAHs. This proposed rule 
would implement amendments made by the following sections of Public Law 
108-173:
    Section 401, which provides that, for discharges occurring in a 
fiscal year beginning with FY 2004 under the IPPS, Medicare will pay 
hospitals in rural and small urban areas in the 50 States using the 
standardized amount (computed for the previous fiscal year) that would 
be used to pay hospitals in large urban areas (or beginning with FY 
2005, for all hospitals in the previous fiscal year), increased by the 
appropriate market basket percentage increase. One standardized amount 
for hospitals in Puerto Rico would be established that would equal the 
amount for hospitals in large urban areas in Puerto Rico.
    Section 402, which provides that for discharges occurring on or 
after April 1, 2004, the DSH payment adjustment for a hospital that is 
not a large urban or large rural hospital will be calculated using the 
current DSH adjustment formula for large urban hospitals, subject to a 
limit of 12 percent for any of these hospitals that are not rural 
referral centers. (There is no limit on the DSH payment percentage for 
rural referral centers.)
    Section 403, which provides that, for discharges occurring on or 
after October 1, 2004, a hospital's labor-related share to which the 
wage index is applied will be decreased to 62 percent of the 
standardized amount when such a change will result in higher total 
payments to the hospital. This provision also applies to the labor-
related share of the standardized amount for hospitals in Puerto Rico.
    Section 405(a), which provides that inpatient, outpatient, and 
covered SNF services provided by a CAH will be reimbursed at 101 
percent of reasonable costs for services furnished to Medicare 
beneficiaries. This provision is applicable to payments for services 
furnished during cost reporting periods beginning on or after January 
1, 2004.
    Section 405(b), which expands coverage of the costs associated with 
covered Medicare services furnished by on-call emergency room providers 
in CAHs to include services furnished by physician assistants, nurse 
practitioners, and clinical nurse specialists, effective for costs 
incurred for services furnished on or after January 1, 2005.
    Section 405(c), which provides that eligible CAHs may receive 
payments for their inpatient services on a periodic interim payment 
(PIP) basis, effective

[[Page 28202]]

with payments made on or after July 1, 2004.
    Section 405(d), which allows CAHs to elect to receive payments 
under the optional payment method (a payment encompassing both 
inpatient CAH services and physician and practitioner services to 
outpatients) even if some practitioners do not reassign to the CAH 
their rights to bill for professional services to CAH outpatients. This 
provision applies to cost reporting periods occurring on or after July 
1, 2004, except that in the case of a CAH that made an election of the 
optional payment method before November 1, 2003, the provision applies 
to cost reporting periods beginning on or after July 1, 2001.
    Section 405(e), which increases the limit on the number of beds 
that a CAH may have for acute care from 15 to 25 beds. This provision 
applies to CAH designations made before, on, or after January 1, 2004. 
Any election made in accordance to the regulations promulgated to 
implement this provision will only apply prospectively.
    Section 405(g), which provides that a CAH may establish psychiatric 
and rehabilitation distinct part units and limits the number of beds in 
each unit to no more than 10. Services in these distinct part units 
will be paid under the reasonable cost-based methodology. This 
provision applies to cost reporting periods beginning on or after 
October 1, 2004.
    Section 405(h), which terminates a State's authority to waive the 
location requirement for a CAH by designating the CAH as the necessary 
provider, effective January 1, 2006. A grandfathering provision is 
included for CAHs that are certified as necessary providers prior to 
January 1, 2006, which allows any CAH that is designated as a necessary 
provider in its State's rural health plan prior to January 1, 2006, to 
maintain its necessary provider designation.
    Section 406, which provides for a graduated adjustment to the 
inpatient prospective payment rates to account for the higher costs 
associated with hospitals described under section 1886(d) of the Act 
that are located more than 25 road miles from another subsection (d) 
hospital and that have less than 800 discharges during a fiscal year, 
effective for discharges occurring on or after October 1, 2004. The 
increase in these payments may not be greater than 25 percent and the 
determination of the percentage payment increase is not subject to 
administrative or judicial review.
    Section 410A, which authorizes the Secretary to establish a 
demonstration program to test the feasibility and advisability of the 
establishment of rural community hospitals to furnish covered inpatient 
hospital services to Medicare beneficiaries. The Secretary must select 
up to 15 rural community hospitals to participate in the demonstration. 
The Secretary must implement the demonstration program not later than 
January 1, 2005, but may not implement the program before October 1, 
2004.
    Section 422(a), which provides that a hospital's GME FTE resident 
cap will be reduced, and the reduction will be redistributed among 
other hospitals if the hospital's resident count is less than its 
resident cap (rural hospitals with less than 250 acute care inpatient 
beds will be exempt) in a particular reference period. This provision 
is effective for cost reporting periods occurring on or after July 1, 
2005.
    Section 422(b), which specifies that the formula multiplier for the 
IME adjustment is 0.66 for FTE residents attributable to redistributed 
resident positions, effective for discharges occurring on or after July 
1, 2005.
    Section 501, which provides the update factor for payments for the 
hospital inpatient operating costs for FY 2005 and subsequent fiscal 
years is the market basket percentage increase. For FYs 2005 through 
2007, the update factor will be the market basket percentage increase 
minus 0.4 percentage points for any ``subsection (d) hospital'' that 
does not submit hospital quality data on 10 measures as specified by 
the Secretary.
    Section 502, which modifies the IME formula multiplier to be used 
in the calculation of the IME adjustment for midway through FY 2004 and 
provides a new schedule of formula multipliers for FYs 2005 and 
thereafter.
    Section 503(a), which includes a requirement for updating the ICD-
9-CM diagnosis and procedure codes in April 1 of each year, in addition 
to the current process of annual updates on October 1 of each year. 
This change will not affect Medicare payments or DRG classifications 
until the fiscal year that begins after that date.
    Section 503(b), which provides for changes to the threshold amount 
for determining eligibility of new technologies or medical services for 
add-on payments; provides for public input on applications for new 
technology or medical service add-on payments prior to the publication 
of a proposed rule; provides for reconsideration of applications 
received for FY 2004 that were denied; provides for preference in the 
use of DRG adjustments; and provides that new technology or medical 
service payments shall not be budget neutral. This provision is 
effective for fiscal years beginning in FY 2005.
    Section 504, which increases the national portion of the operating 
PPS payment rate for hospitals in Puerto Rico from 50 percent of the 
Federal rate to 75 percent of the Federal rate and decreases the Puerto 
Rico portion of the operating PPS payment from 50 percent to 25 
percent, effective for discharges occurring on or after October 1, 
2004. For the period of April 1, 2004 through September 30, 2004, 
payments for hospitals in Puerto Rico will be based on 62.5 percent 
Federal rate and 37.5 percent of the Puerto Rico rate.
    Section 505, which provides for an increase in a hospital's wage 
index value to take into consideration a commuter wage adjustment for 
hospital employees who reside in a county and work in a different area 
with a higher wage index.
    Section 508, which provides for the establishment of a one-time 
process for a hospital to appeal its geographic classification for wage 
index purposes. By law, any reclassification resulting from this one-
time appeal applies for a 3-year period to discharges occurring on or 
after April 1, 2004.
    Section 711, which freezes the annual CPI-U updates to hospital-
specific per resident amount (PRAs) for GME payments for those PRAs 
that exceed the ceiling, effective for cost reporting periods beginning 
FY 2004 through FY 2013.
    Section 712, which provides for an exception to the initial 
residency period for purposes of direct GME payments for geriatric 
residency or fellowship programs that allows the 2 years spent in an 
approved geriatric program to be counted as part of the resident's 
initial training period, but not to count against any limitation on the 
initial residency period. This provision is effective for cost 
reporting periods beginning on or after October 1, 2003.
    Section 713, which, during a 1-year moratorium period of January 1, 
2004 through December 31, 2004, allows hospitals to count allopathic or 
osteopathic family practice residents training in nonhospital settings 
for IME and direct GME purposes, without regard to the financial 
arrangement between the hospital and the teaching physician practicing 
in the nonhospital setting to which the resident is assigned.
    Section 733, which provides for the Medicare payment of routine 
costs, as well as costs relating to the transplantation and appropriate 
related items and services, for Medicare beneficiaries participating in 
a clinical trial involving pancreatic islet cell

[[Page 28203]]

transplantation, beginning no earlier than October 1, 2004.
    Section 926, which requires the Secretary to make information 
publicly available that enables hospital discharge planners, Medicare 
beneficiaries, and the public to identify skilled nursing facilities 
(SNFs) that are participating in the Medicare program, and requires a 
hospital, as part of its discharge planning, to evaluate a patient's 
need for SNF care.
    Section 947, which requires that, by July 1, 2004, hospitals not 
otherwise subject to the Occupational Safety and Health Act (OSHA) (or 
a State occupational safety and health plan that is approved under 
section 18(b) of that Act) must comply with the OSHA bloodborne 
pathogens (BBP) standard as part of their Medicare provider agreements.

C. Major Contents of This Proposed Rule

    In this proposed rule, we are setting forth proposed changes to the 
Medicare IPPS for operating costs and for capital-related costs under 
the IPPS for FY 2005. We also are setting forth proposed changes 
relating to payments for GME costs, payments to certain hospitals and 
units that continue to be excluded from the IPPS and paid on a 
reasonable cost basis, payments for DSH, requirements and payments for 
CAHs, conditions of participation for hospitals relating to discharge 
planning and fire safety requirements, requirements for Medicare 
provider agreements relating to bloodborne pathogen standards, and QIO 
disclosure of information requirements. The changes being proposed 
would be effective for discharges occurring on or after October 1, 
2004, unless otherwise noted.
    The following is a summary of the major changes that we are 
proposing to make:
1. Proposed Changes to the DRG Reclassifications and Recalibrations of 
Relative Weights
    As required by section 1886(d)(4)(C) of the Act, we are proposing 
annual adjustments to the DRG classifications and relative weights. 
Based on analyses of Medicare claims data, in section II. of this 
preamble, we are proposing to establish a number of new DRGs and make 
changes to the designation of diagnosis and procedure codes under other 
existing DRGs. Our proposed changes for FY 2005 are set forth in 
section II. of this preamble.
    Among the proposed changes discussed are:
     Restructuring and retitling of several DRGs to reflect 
expanded coverage of heart assist systems such as ventricular assist 
devices (VAD) or left ventricular assist devices (LVAD) as destination 
(or permanent) therapy for end-stage heart failure patients who are not 
candidates for heart transplantation: DRG 103 (Heart Transplant or 
Implant of Heart Assist System) (proposed title change), DRG 104 
(Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac 
Catheterization) and DRG 105 (Cardiac Valve and Other Major 
Cardiothoracic Procedures Without Cardiac Catheterization), and DRG 525 
(Other Heart Assist System Implant) (proposed title change).
     Addition of pacemaker device and lead procedure code 
combinations that could lead to the assignment of DRG 115 (Permanent 
Cardiac Pacemaker Implant with Acute Myocardial Infarction, Heart 
Failure, or Shock or ACID Lead or Generator Procedures) and DRG 116 
(Other Permanent Cardiac Pacemaker Implant).
     Movement of the procedure code for 360 spinal fusion from 
DRG 496 (Combined Anterior/Posterior Spinal Fusion) to DRG 497 (Spinal 
Fusion Except Cervical With CC) and DRG 498 (Spinal Fusion Except 
Cervical Without CC).
     Addition of combination codes, which also include heart 
failure, to the list of major problems under DRG 387 (Prematurity With 
Major Problems) and DRG 389 (Full-Term Neonate With Major Problems).
     Modification of DRGs 504 through 509 under MDC 22 (Burns) 
to recognize the impact of long-term mechanical ventilation on burn 
cases and renaming DRG 504 as proposed title ``Extensive Burns or Full 
Thickness Burns With Mechanical Ventilation 96+ Hours With Skin Graft'' 
and DRG 505 as proposed title ``Extensive Burns or Full Thickness Burns 
With Mechanical Ventilation 96+ Hours Without Skin Graft.''
     Deletion of DRG 483 (Tracheostomy for Face, Mouth, and 
Neck Diagnoses) and splitting the assignment of cases to two proposed 
new DRGs on the basis of the performance of a major operating room 
procedure: proposed new DRGs 541 and 542 (Tracheostomy With Mechanical 
Ventilation 96+ Hours or Principal Diagnosis Except Face, Mouth, and 
Neck Diagnosis With and Without Major Operating Room Procedure, 
respectively).
    We also are presenting our reevaluation of FY 2004 applicants for 
add-on payments for high-cost new medical services and technologies, 
and our analysis of FY 2005 applicants (including public input, as 
directed by Public Law 108-173, obtained in a town meeting).
    We are proposing the annual update of the long-term care diagnosis-
related group (LTC-DRG) classifications and relative weights for use 
under the LTCH PPS for FY 2005.
2. Proposed Changes to the Hospital Wage Index
    In section III. of this preamble, we are proposing revisions to the 
wage index and the annual update of the wage data. Specific issues 
addressed in this section included the following:
     The proposed FY 2005 wage index update, using wage data 
from cost reporting periods that began during FY 2001.
     Proposed revised labor market areas as a result of OMB 
revised definitions of geographical statistical areas.
     A discussion of the collection of occupational mix data 
and the proposed occupational mix adjustment to the wage index that we 
are proposing to apply beginning October 1, 2004.
     The proposed revisions to the wage index based on hospital 
redesignations and reclassifications, including changes that reflect 
the new OMB standards for assignment of hospitals to geographic areas.
     The proposed adjustment to the wage index based on 
commuting patterns of hospital employees who reside in a county and 
work in a different area with a higher wage index, to implement section 
505 of Public Law 108-173.
     A discussion of eligible hospitals reclassified under the

4. Proposed Changes to the PPS for Capital-Related Costs
    In section V. of this preamble, we discuss the payment requirements 
for capital-related costs and propose changes relating to capital 
payments to hospitals located in Puerto Rico, changes in the policies 
on exception payments for extraordinary circumstances, treatment of 
hospitals previously reclassified for the operating standardized 
amounts, and capital payment adjustments based on the proposed changes 
in geographic classifications.
5. Proposed Changes for Hospitals and Hospital Units Excluded From the 
IPPS
    In section VI. of this preamble, we discuss the following proposed 
revisions and clarifications concerning excluded hospitals and hospital 
units and CAHs:
     Proposed changes in the payment rate for new excluded 
hospitals.
     Proposed changes to the criteria for determining payments 
to hospitals-within-hospitals.
     Proposed changes to the policies governing payment to 
CAHs, including a change in the payment percentage for services 
furnished by CAHs; changes in the rules governing the election by a CAH 
of the optional method of payment; expansion of the payment to 
emergency room on-call providers to include physician assistants, nurse 
practitioners, and clinical nurse specialists; authorization for the 
making of periodic interim payments (PIPs) for CAHs for inpatient 
services furnished; revision of the bed count limit for CAHs from 15 to 
25 acute care beds; proposed requirements for establishing psychiatric 
and rehabilitation distinct part units in CAHs; and termination of the 
location requirement for a CAH by designating the CAH as a necessary 
provider.
6. Proposed Changes to QIO Disclosure of Information Requirements
    In section VII. of this preamble, we discuss our proposed 
clarification of the requirements for disclosure by QIOs of information 
on institutions and practitioners collected in the course of the QIO's 
quality improvement activities.
7. Proposed Changes Relating to Medicare Provider Agreements, Hospital 
Conditions of Participation, and Fire Safety Requirements for Certain 
Health Care Facilities
    In section VIII. of this preamble, we are proposing to--
     Require hospitals, as part of the discharge planning 
standard under the Medicare hospital conditions of participation, to 
furnish a list of Medicare-participating home health agencies to 
patients who receive home health services after discharge and to 
provide information on Medicare-certified SNFs to patients who are 
likely to need posthospital extended care services.
     Require that Medicare provider agreements include 
provisions that would ensure that all hospital employees who may come 
into contact with human blood in the course of their duties are 
provided proper protection from bloodborne pathogens.
     Correct a technical error relating to the application of 
the 2000 edition of the Life Safety Code as the fire safety 
requirements for certain health care facilities; and clarify the 
effective date for the prohibition on the use of roller latches in 
these facilities.
8. Determining Prospective Payment Operating and Capital Rates and 
Rate-of-Increase Limits
    In the Addendum to this proposed rule, we set forth proposed 
changes to the amounts and factors for determining the FY 2005 
prospective payment rates for operating costs and capital-related 
costs. We also establish the proposed threshold amounts for outlier 
cases. In addition, we address proposed update factors for determining 
the rate-of-increase limits for cost reporting periods beginning in FY 
2005 for hospitals and hospital units excluded from the PPS.
9. Impact Analysis
    In Appendix A of the proposed rule, we set forth an analysis of the 
impact that the proposed changes would have on affected hospitals.
10. Recommendation of Update Factor for Hospital Inpatient Operating 
Costs
    In Appendix B of this proposed rule, as required by sections 
1886(e)(4) and (e)(5) of the Act, we provide our recommendations of the 
appropriate percentage changes for FY 2005 for the following:
     A single average standardized amount for all areas for 
hospital inpatient services paid under the IPPS for operating costs 
(and hospital-specific rates applicable to SCHs and MDHs).
     Target rate-of-increase limits to the allowable operating 
costs of hospital inpatient services furnished by hospitals and 
hospital units excluded from the IPPS.
11. Discussion of Medicare Payment Advisory Commission Recommendations
    Under section 1805(b) of the Act, the Medicare Payment Advisory 
Commission (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. MedPAC's March 2004 recommendation

[[Page 28205]]

concerning hospital inpatient payment policies addressed only the 
update factor for inpatient hospital operating costs and capital-
related costs under the IPPS and for hospitals and distinct part 
hospital units excluded from the IPPS. This recommendation is addressed 
in Appendix B. For further information relating specifically to the 
MedPAC March 1 report or to obtain a copy of the report, contact MedPAC 
at (202) 220-3700 or visit MedPAC's Web site at: http://www.medpac.gov.


II. Proposed Changes to DRG Classifications and Relative Weights

A. Background

    Section 1886(d) of the Act specifies that the Secretary shall 
establish a classification system (referred to as DRGs) for inpatient 
discharges and adjust payments under the IPPS based on appropriate 
weighting factors assigned to each DRG. Therefore, under the IPPS, we 
pay for inpatient hospital services on a rate per discharge basis that 
varies according to the DRG to which a beneficiary's stay is assigned. 
The formula used to calculate payment for a specific case multiplies an 
individual hospital's payment rate per case by the weight of the DRG to 
which the case is assigned. Each DRG weight represents the average 
resources required to care for cases in that particular DRG, relative 
to the average resources used to treat cases in all DRGS.
    Congress recognized that it would be necessary to recalculate the 
DRG relative weights periodically to account for changes in resource 
consumption. Accordingly, section 1886(d)(4)(C) of the Act requires 
that the Secretary adjust the DRG classifications and relative weights 
at least annually. These adjustments are made to reflect changes in 
treatment patterns, technology, and any other factors that may change 
the relative use of hospital resources. The proposed changes to the DRG 
classification system and the proposed recalibration of the DRG weights 
for discharges occurring on or after October 1, 2004, are discussed 
below.

B. DRG Reclassifications

    [If you choose to comment on issues in this section, please include 
the caption ``DRG Reclassifications'' at the beginning of your 
comment.]
1. General
    Cases are classified into DRGs for payment under the IPPS based on 
the principal diagnosis, up to eight additional diagnoses, and up to 
six procedures performed during the stay. In a small number of DRGs, 
classification is also based on the age, sex, and discharge status of 
the patient. The diagnosis and procedure information is reported by the 
hospital using codes from the International Classification of Diseases, 
Ninth Revision, Clinical Modification (ICD-9-CM).
    For FY 2004, cases are assigned to one of 522 DRGs in 25 major 
diagnostic categories (MDCs). Most MDCs are based on a particular organ 
system of the body. For example, MDC 6 is Diseases and Disorders of the 
Digestive System. This approach is used because clinical care is 
generally organized in accordance with the organ system affected. 
However, some MDCs are not constructed on this basis because they 
involve multiple organ systems (for example, MDC 22 (Burns)). The table 
below lists the 25 MDCs.

------------------------------------------------------------------------
                   Major diagnostic categories (MDCs).
-------------------------------------------------------------------------
1--Diseases and Disorders of the Nervous System.
2--Diseases and Disorders of the Eye.
3--Diseases and Disorders of the Ear, Nose, Mouth, and Throat.
4--Diseases and Disorders of the Respiratory System.
5--Diseases and Disorders of the Circulatory System.
6--Diseases and Disorders of the Digestive System.
7--Diseases and Disorders of the Hepatobiliary System and Pancreas.
8--Diseases and Disorders of the Musculoskeletal System and Connective
 Tissue.
9--Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast.
10--Endocrine, Nutritional and Metabolic Diseases and Disorders.
11--Diseases and Disorders of the Kidney and Urinary Tract.
12--Diseases and Disorders of the Male Reproductive System.
13--Diseases and Disorders of the Female Reproductive System.
14--Pregnancy, Childbirth, and the Puerperium.
15--Newborns and Other Neonates with Conditions Originating in the
 Perinatal Period.
16--Diseases and Disorders of the Blood and Blood Forming Organs and
 Immunological Disorders.
17--Myeloproliferative Diseases and Disorders and Poorly Differentiated
 Neoplasms.
18--Infectious and Parasitic Diseases (Systemic or Unspecified Sites).
19--Mental Diseases and Disorders.
20--Alcohol/Drug Use and Alcohol/Drug Induced Organic Mental Disorders.
21--Injuries, Poisonings, and Toxic Effects of Drugs.
22--Burns.
23--Factors Influencing Health Status and Other Contacts with Health
 Services.
24--Multiple Significant Trauma.
25--Human Immunodeficiency Virus Infections
------------------------------------------------------------------------

    In general, cases are assigned to an MDC based on the patient's 
principal diagnosis before assignment to a DRG. However, for FY 2004, 
there are eight DRGs to which cases are directly assigned on the basis 
of ICD-9-CM procedure codes. These DRGs are for heart, liver, bone 
marrow, lung, simultaneous pancreas/kidney, and pancreas transplants 
and for tracheostomies. Cases are assigned to these DRGs before they 
are classified to an MDC. The table below lists the current eight pre-
MDCs.

------------------------------------------------------------------------
               Pre-Major Diagnostic Categories (Pre-MDCs)
-------------------------------------------------------------------------
DRG 103--Heart Transplant.
DRG 480--Liver Transplant.

[[Page 28206]]


DRG 481--Bone Marrow Transplant.
DRG 482--Tracheostomy for Face, Mouth, and Neck Diagnoses.
DRG 483--Tracheostomy with Mechanical Ventiliation 96+ Hours or
 Principal Diagnosis Except for Face, Mouth, and Neck Diagnoses.
DRG 495--Lung Transplant.
DRG 512--Simultaneous Pancreas/Kidney Transplant.
DRG 513--Pancreas Transplant
------------------------------------------------------------------------

    Within most MDCs, cases are then divided into surgical DRGs and 
medical DRGs. Surgical DRGs are based on a hierarchy that orders 
operating room (O.R.) procedures or groups of O.R. procedures by 
resource intensity. Medical DRGs generally are differentiated on the 
basis of diagnosis and age (less than or greater than 17 years of age). 
Some surgical and medical DRGs are further differentiated based on the 
presence or absence of a complication or a comorbidity (CC).
    Generally, nonsurgical procedures and minor surgical procedures 
that are not usually performed in an operating room are not treated as 
O.R. procedures. However, there are a few non-O.R. procedures that do 
affect DRG assignment for certain principal diagnoses, for example, 
extracorporeal shock wave lithotripsy for patients with a principal 
diagnosis of urinary stones.
    Patient's diagnosis, procedure, discharge status, and demographic 
information is fed into the Medicare claims processing systems and 
subjected to a series of automated screens called the Medicare Code 
Editor (MCE). The MCE screens are designed to identify cases that 
require further review before classification into a DRG.
    After patient information is screened through the MCE and any 
further development of the claim is conducted, the cases are classified 
into the appropriate DRG by the Medicare GROUPER software program. The 
GROUPER program was developed as a means of classifying each case into 
a DRG on the basis of the diagnosis and procedure codes and, for a 
limited number of DRGs, demographic information (that is, sex, age, and 
discharge status).
    After cases are screened through the MCE and assigned to a DRG by 
the GROUPER, a base DRG payment is calculated by the PRICER software. 
The PRICER calculates the payments for each case covered by the IPPS 
based on the DRG relative weight and additional factors associated with 
each hospital, such as IME and DSH adjustments. These additional 
factors increase the payment amount to hospitals above the base DRG 
payment.
    The records for all Medicare hospital inpatient discharges are 
maintained in the Medicare Provider Analysis and Review (MedPAR) file. 
The data in this file are used to evaluate possible DRG classification 
changes and to recalibrate the DRG weights. However, in the July 30, 
1999 IPPS final rule (64 FR 41500), we discussed a process for 
considering non-MedPAR data in the recalibration process. In order for 
us to consider using particular non-MedPAR data, we must have 
sufficient time to evaluate and test the data. The time necessary to do 
so depends upon the nature and quality of the non-MedPAR data 
submitted. Generally, however, a significant sample of the non-MedPAR 
data should be submitted by mid-October for consideration in 
conjunction with the next year's proposed rule. This allows us time to 
test the data and make a preliminary assessment as to the feasibility 
of using the data. Subsequently, a complete database should be 
submitted by early December for consideration in conjunction with the 
next year's proposed rule.
    Many of the changes to the DRG classifications are the result of 
specific issues brought to our attention by interested parties. We 
encourage individuals with concerns about DRG classifications to bring 
those concerns to our attention in a timely manner so they can be 
carefully considered for possible inclusion in the next proposed rule 
and so any proposed changes may be subjected to public review and 
comment. Therefore, similar to the timetable for interested parties to 
submit non-MedPAR data for consideration in the DRG recalibration 
process, concerns about DRG classification issues should be brought to 
our attention no later than early December in order to be considered 
and possibly included in the next annual proposed rule updating the 
IPPS.
    The changes we are proposing to the DRG classification system for 
the FY 2005 GROUPER version 22.0 and to the methodology used to 
recalibrate the DRG weights are set forth below. Unless otherwise noted 
in this proposed rule, our DRG analysis is based on data from the 
December 2003 update of the FY 2003 MedPAR file, which contains 
hospital bills received through December 31, 2003 for discharges in FY 
2003.
2. MDC 1 (Diseases and Disorders of the Nervous System): Intracranial 
Hemorrhage and Stroke With Infarction
    It has come to our attention that the title of DRG 14 (Intracranial 
Hemorrhage and Stroke With Infarction) may be misleading because it 
implies that a combination of conditions exists when the DRG is 
assigned. When we developed this title, we did not intend to imply that 
a combination of conditions exists. Therefore, we are proposing to 
change the title of DRG 14 to read ``Intracranial Hemorrhage or 
Cerebral Infarction''.
3. MDC 5 (Diseases and Disorders of the Circulatory System)
a. Heart Assist System Implant
    Circulatory support devices, also known as heart assist systems, 
ventricular assist devices (VADs) or left ventricular assist devices 
(LVADs), offer a surgical alternative for end-stage heart failure 
patients. This type of device is often implanted near a patient's 
native heart and assumes the pumping function of the weakened heart's 
left ventricle. In many cases, heart transplantation would be the 
treatment of choice for this type of patient. However, the low number 
of donor hearts limits this treatment option.
    We have reviewed the payment and DRG assignment for this type of 
device many times in the past. The reader is referred to the August 1, 
2002 IPPS final rule (67 FR 49989) for a complete listing of those 
discussions.
    In the August 1, 2002 final rule (67 FR 49990), we attempted to 
clinically and financially align VAD procedures by creating new DRG 525 
(Heart Assist System Implant). We also noted that cases in which a 
heart transplant also occurred during the same hospitalization episode 
would continue to be assigned to DRG 103 (Heart Transplant). At that 
time, we announced that DRG 525 would consist of any principal 
diagnosis in MDC 5, plus one of the following surgical procedure codes:

 37.62, Insertion of nonimplantable heart assist system
 37.63, Repair of heart assist system

[[Page 28207]]

 37.65, Implant of external heart assist system
 37.66, Insertion of implantable heart assist system

    (To avoid confusion, we note that the titles of codes 37.62, 37.63, 
37.65, and 37.66 have been revised for FY 2005 through the ICD-9-CM 
Coordination and Maintenance Committee process as reflected in Table 
6F, Revised Procedure Code Titles in the Addendum to this proposed 
rule.)
    Commenters on the May 19, 2003 proposed rule that preceded the 
August 1, 2003 IPPS (FY 2004) final rule notified us that procedure 
code 37.66 was neither a clinical nor a financial match to the rest of 
the procedure codes now assigned to DRG 525. We did not modify DRG 525 
for FY 2004. We agreed that we would continue to evaluate whether to 
make further changes to DRG 525. After publication of the August 1, 
2003 final rule, we again reviewed the MedPAR data concerning DRG 525, 
and came to the conclusion that procedure code 37.62 is different in 
terms of clinical procedures and resource utilization from the other 
procedure codes assigned to DRG 525. Therefore, in a correction to the 
August 1, 2003 IPPS (FY 2004) final rule, published on October 6, 2003 
(68 FR 57733), we revised the composition of DRG 525 by correcting the 
assignment of procedures to DRG 525 in light of the lower charges 
associated with procedure code 37.62. We moved code 37.62 into DRG 104 
(Cardiac Valve and Other Major Cardiothoracic Procedures With Cardiac 
Catheterization) and DRG 105 (Cardiac Valve and Other Major 
Cardiothoracic Procedures Without Cardiac Catheterization), and left 
procedure codes 37.63, 37.65, and 37.66 in DRG 525.
    In addition, we have evaluated a request for expanded coverage for 
VADs and LVADs as destination (or permanent) therapy for end-stage 
heart failure patients who are not candidates for heart 
transplantation. VADs and LVADs had been approved for support of blood 
circulation post-cardiotomy (effective for services performed on or 
after October 18, 1993) and as a bridge to heart transplant (effective 
for services performed on or after January 22, 1996) to assist a 
damaged or weakened heart in pumping blood. The criteria that must be 
fulfilled in order for Medicare coverage to be provided for these 
purposes have been previously discussed in the August 1, 2000 final 
rule (65 FR 47058), and can also be accessed online at: http://www.cms.gov/manuals/pm_trans/r2ncd1.pdf
.

    As a result of that review, effective for services performed on or 
after October 1, 2003, VADs have been approved as destination therapy 
for patients requiring permanent mechanical cardiac support. Briefly, 
VADs used for destination therapy are covered only if they have 
received approval from the FDA for that purpose, and the device is used 
according to the FDA-approved labeling instructions. VADs are covered 
for patients who have chronic end-stage heart failure (New York Heart 
Association Class IV end-stage left ventricular failure for at least 90 
days with a life expectancy of less than 2 years). Implanting 
facilities as well as patients must also meet all of the additional 
conditions that are listed in the national coverage determination for 
artificial hearts and related devices, which is posted on the above CMS 
Web site.
    In light of the new indication of destination therapy, we again 
reviewed the FY 2003 MedPAR data for all cases in which a VAD had been 
implanted, using the criterion of any case containing a procedure code 
of 37.66. We found a total of 65 cases in 3 DRGs: DRG 103 (Heart 
Transplant); DRG 483 (Tracheostomy With Mechanical Ventilation 96+ 
Hours or Principal Diagnosis Except Face, Mouth, and Neck Diagnoses); 
and DRG 525 (Heart Assist System Implant). The following table displays 
our findings:

----------------------------------------------------------------------------------------------------------------
                                                                                  Average length      Average
                  DRG with code 37.66 reported                         Count          of stay         charges
----------------------------------------------------------------------------------------------------------------
103.............................................................              14           77.36        $836,011
483.............................................................               6          100.50       1,400,706
525.............................................................              45           38.93         308,725
----------------------------------------------------------------------------------------------------------------

    The remaining 354 cases in DRG 103 that did not report code 37.66 
had average charges of $282,578. The remaining 171 cases in DRG 525 
that did not contain code 37.66 had an average length of stay of 12.39 
days and average charges of $168,388. The 45 cases in DRG 525 with code 
37.66 accounted for 26 percent of the cases. However, the average 
charges for these cases are approximately $140,340 higher than the 
average charges for cases in DRG 525 that did not report code 37.66.
    Commenters on the FY 2004 final rule suggested adding code 37.66 to 
DRG 103. We were concerned with the timing of that comment, as it was 
received after publication of the proposed rule. We noted that the 
commenter's suggestions on the structure of the DRGs involved were 
significant, and that change of that magnitude should be subject to 
public review and comment. We also noted that we would evaluate the 
suggestion further. (68 FR 45370) However, as one of the indications 
for this device has become destination therapy, and as this new 
indication is more clinically aligned with DRG 103, we are proposing to 
remove procedure code 37.66 from DRG 525 and assign it to DRG 103. We 
also are proposing to change the title of DRG 103 to ``Heart Transplant 
or Implant of Heart Assist System''. The proposed restructured DRG 103 
would include any principal diagnosis in MDC 5, plus one of the 
following surgical procedure codes:

 33.6, Combined heart-lung transplantation
 37.51, Heart transplantation
 37.66, Insertion of implantable heart assist system

    In addition to the proposed changes to DRG 103, we are proposing to 
change the title of DRG 525 to ``Other Heart Assist System Implant''.
    In conjunction with the above data review, we also looked at DRGs 
104 and 105.
    DRGs 104 and 105 had been restructured in FY 2003 by assigning code 
37.62 to them. (Note: The code title for 37.62 has been revised, 
effective FY 2005, as reflected in Table 6F of the Addendum to this 
proposed rule). We examined the MedPAR data and found that the average 
charges were $113,667 and $82,899, respectively, for DRGs 104 and 105 
for cases not reporting code 37.62, while cases containing code 37.62 
had average charges of $124,559 and $166,129, respectively.
    The removal of code 37.66 from DRG 525 would have the effect of 
clinically realigning that DRG to be more coherent. As a result of the 
proposal to remove code 37.66 from DRG 525 and assign it to DRG 103, we 
also are proposing to remove code 37.62 from DRGs 104 and 105 and 
assign it back into DRG 525. In addition, the average

[[Page 28208]]

charges for code 37.62 shown above in DRGs 104 and 105 ($124,559 and 
$166,129) more closely match the average charges reported for the 171 
cases in DRG 525, absent code 37.66 ($168,388).
    The proposed restructured DRG 525 would include any principal 
diagnosis in MDC 5, plus the following surgical procedure codes:

 37.52, Implantation of total replacement heart system*
 37.53, Replacement or repair of thoracic unit of total 
replacement heart system*
 37.54, Replacement or repair of other implantable component of 
total replacement heart system*
 37.62, Insertion of nonimplantable heart assist system
 37.63, Repair of heart assist system
 37.65, Implant of external heart assist system
*These codes represent noncovered services for Medicare beneficiaries. 
However, it is our longstanding practice to assign every code in the 
ICD-9-CM classification to a DRG. Therefore, they have been assigned to 
DRG 525.
b. Cardiac Resychronization Therapy and Heart Failure
    We received a request from a manufacturer of a Cardiac 
Resynchronization Therapy Defibrillator (CRT-D) device for a 
modification to DRG 535 (Cardiac Defibrillator Implant With Cardiac 
Catheterization With Acute Myocardial Infarction/Heart Failure/Shock) 
and DRG 536 (Cardiac Defibrillator Implant With Cardiac Catheterization 
Without Acute Myocardial Infarction/Heart Failure/Shock). The commenter 
pointed out that defibrillator device implantations, including the CRT-
D type of defibrillator, are assigned to DRG 535 when the patient also 
has a cardiac catheterization and has either an acute myocardial 
infarction, heart failure, or shock as a principal diagnosis. If the 
patient receiving the defibrillator implant and cardiac catheterization 
does not have a principal diagnosis of acute myocardial infarction, 
heart failure, or shock, the cases are assigned to DRG 536.
    The commenter requested that cases be assigned to DRG 535 when the 
patient has heart failure as either a principal diagnosis or a 
secondary diagnosis. The commenter stated that patients receive a CRT-D 
(as opposed to other types of defibrillators) when they have both heart 
failure and arrhythmia. The commenter was concerned that some coders 
may sequence the heart failure as a secondary diagnosis, which would 
result in the patient being assigned to DRG 536.
    As stated earlier, DRGs 535 and 536 are split based on the 
principal diagnosis of acute myocardial infarction, heart failure, or 
shock. Cases are not assigned to DRG 535 when heart failure is a 
secondary diagnosis.
    The commenter described a scenario where a patient was admitted 
with heart failure for an evaluation of the need for a CRT-D 
implantation. The hospitalization studies indicated that the patient 
had a ventricular tachycardia. The commenter indicated that coders 
would be confused as to which code should be listed as the principal 
diagnosis.
    CMS' review of this scenario as described would be that the heart 
failure led to the admission and would be the principal diagnosis. This 
case would properly be assigned to DRG 535. Furthermore, when two 
conditions are considered to be equally responsible for the admission, 
either one of the two conditions may be selected as the principal 
diagnosis.
    The commenter also stated that its own study shows CRT-D patients 
have significantly higher charges than do other patients in DRGs 535 
and 536 who receive an implantable defibrillator. This was the case 
whether heart failure was used as a principal or secondary diagnosis.
    A cardiac catheterization is a diagnostic procedure generally 
performed to establish the nature of the patient's cardiac problem and 
determine if implantation of a cardiac defibrillator is appropriate. 
Generally, the cardiac catheterization can be done on an outpatient 
basis. Patients who are admitted with acute myocardial infarction, 
heart failure, or shock and have a cardiac catheterization are 
generally acute patients who require emergency implantation of the 
defibrillator. Thus, there are very high costs associated with these 
patients.
    We examined the MedPAR file for all cases in DRGs 535 and 536 and 
only cases in DRG 536 in which acute myocardial infarction or heart 
failure was listed as a secondary diagnosis. The following chart 
illustrates the results of our findings:

----------------------------------------------------------------------------------------------------------------
                                                                            Average length of
                          DRGs                                 Count               stay         Average charges

 Defibrillator Implant With Cardiac Catheterization
 Without Acute Myocardial Infarction/Heart Failure/
 Shock.................................................
----------------------------------------------------------------------------------------------------------------

    The data show that cases with a secondary diagnosis of acute 
myocardial infarction or heart failure have average charges 
($94,832.14) closer to the overall average charges for DRG 536 
($89,493.85) where they are currently assigned. Overall charges for DRG 
535 were $110,663.57. We do not believe these data support modifying 
DRG 535 and DRG 536 as requested. Many of the CRT-D patients who are 
admitted for heart failure would be assigned into DRG 535. Furthermore, 
modifying the DRG logic for one specific type of defibrillator (CRT-D) 
is not consistent with our overall policy of grouping similar types of 
patients together in the same DRG. In addition, to modify the DRG logic 
for the small percentage of cases where there might be confusion 
concerning the selection of the principal diagnosis does not seem 
prudent. Therefore, we are not proposing a modification to DRG 535 or 
536 for CRT-Ds.
c. Combination Cardiac Pacemaker Devices and Lead Codes
    We received a comment that recommended that we include additional 
combination procedure codes representing cardiac pacemaker device and 
lead codes under DRG 115 (Permanent Cardiac Pacemaker Implant With 
Acute Myocardial Infarction, Heart Failure, or Shock or ACID Lead or 
Generator Procedures) and DRG 116 (Other Permanent Cardiac Pacemaker 
Implant). DRGs 115 and 116 are assigned when a complete pacemaker unit 
with leads is implanted. Combinations of pacemaker devices and lead 
codes that would lead to the DRG assignment are listed under DRGs 115 
and 116. The commenter recommended that the following pacemaker device 
and lead procedure code combinations be added to these two DRGs:

 00.53 & 37.70

[[Page 28209]]

 00.53 & 37.71
 00.53 & 37.72
 00.53 & 37.73
 00.53 & 37.74
 00.53 & 37.76
    These codes are defined as follows:

 00.53, Implantation or replacement of cardiac 
resynchronization pacemaker, pulse generator only [CRT-P]
 37.70, Initial insertion of pacemaker lead [electrode], not 
otherwise specified
 37.71, Initial insertion of transvenous lead [electrode] into 
ventricle
 37.72, Initial insertion of transvenous lead [electrode] into 
atrium and ventricle
 37.73, Initial insertion of transvenous lead [electrode] into 
atrium
 37.74, Initial insertion or replacement of epicardial lead 
[electrode] into epicadium
 37.76, Replacement of transvenous atrial and/or ventricular 
lead(s) [electrode]
    We have consulted our medical advisors and they agree that these 
recommended procedure code combinations also describe pacemaker device 
and lead implantations and should be included under DRGs 115 and 116. 
Therefore, we are proposing to add the recommended procedure code 
combinations to the list of procedure code combinations under DRGs 115 
and 116.
4. MDC 6 (Diseases and Disorders of the Digestive System): Artificial 
Anal Sphincter
    In the FY 2003 IPPS final rule (67 FR 50242), we created two new 
codes for procedures involving an artificial anal sphincter, effective 
for discharges occurring on or after October 1, 2002: code 49.75 
(Implantation or revision of artificial anal sphincter) that is used to 
identify cases involving implantation or revision of an artificial anal 
sphincter and code 49.76 (Removal of artificial anal sphincter) that is 
used to identify cases involving the removal of the device. In Table 6B 
of that final rule, we assigned both codes to one of four MDCs, based 
on principal diagnosis, and one of six DRGs within those MDCs. In the 
August 1, 2003 IPPS final rule (68 FR 45372), we discussed the 
assignment of these codes in response to a request we had received to 
consider reassignment of these two codes to different MDCs and DRGs. 
The requester believed that the average charges ($44,000) for these 
codes warranted reassignment. In the August 1, 2003 IPPS final rule, we 
stated that we did not have sufficient MedPAR data available on the 
reporting of codes 49.75 and 49.76 to make a determination on DRG 
reassignment of these codes. We agreed that, if warranted, we would 
give further consideration to the DRG assignments of these codes 
because it is our customary practice to review DRG assignment(s) for 
newly created codes to determine clinical coherence and similar 
resource consumption after we have had the opportunity to collect 
MedPAR data on utilization, average length of stay charges, and 
distribution throughout the system.
    Therefore, we reviewed the FY 2003 MedPAR data for the presence of 
codes 49.75 and 49.76. We then arrayed the results by DRG, count, 
average length of stay, charges, and the presence or absence of a 
secondary diagnosis that could be classified as a CC. We found that 
there were a total of 13 cases in 5 total DRGs with CCs, and 9 cases in 
4 total DRGs without CCs, for a total of 22 cases that reported these 
procedure codes. We had anticipated that the majority of cases would 
have been found in DRGs 157 (Anal and Stomal Procedures With CC) and 
158 (Anal and Stomal Procedures Without CC), but found only 2 cases 
grouped to DRG 157 and 4 cases grouped to DRG 158. Our data showed 
average charges of $22,374 for the cases with CC, and average charges 
of $20,831 for the cases without CC. Average charges for DRG 157 were 
$18,196, while average charges for DRG 158 were $9,348.
    Our medical advisors also reviewed the contents of DRGs 157 and 
158. The consensus was that codes 49.75 and 49.76 are not a clinical 
match to the other procedure codes found in these two DRGs. The other 
procedure codes in DRGs 157 and 158 are for simpler and less invasive 
procedures. In some circumstances, these procedures could potentially 
be performed in an outpatient setting or in a physician's office. Our 
medical advisors determined that clinical coherence was not 
demonstrated and recommended that we move these codes to DRGs 146 
(Rectal Resection With CC) and 147 (Rectal Resection Without CC), as 
these anal sphincter procedures more closely resemble the procedures in 
these DRGs. In addition, the average charges for paired DRG 146 
($33,853) and DRG 147 ($21,747) more closely resemble the actual 
average charges found in the MedPAR data for these cases.
    Even though there are few reports of codes 49.75 and 49.76 in the 
MedPAR data and we do not anticipate a significant increase in 
utilization of these procedures, we are proposing that these two codes 
would only be removed from paired DRG 157 and 158 and reassigned to 
paired DRG 146 and 147 under MDC 6 (Diseases and Disorders of the 
Digestive System). All other MDC and DRG assignments for codes 49.75 
and 49.76 would remain the same.
5. MDC 8 (Diseases and Disorders of the Musculoskeletal System and 
Connective Tissue)
a. 360 Spinal Fusions
    We received a comment that suggested procedure code 81.61 (360 
Spinal fusion) should not be included in DRG 496 (Combined Anterior/
Posterior Spinal Fusion). The commenter stated that code 81.61 does not 
represent the same types of cases as other codes included in DRG 496. 
The commenter indicated that cases reported with code 81.61 involve 
making only one incision, and then fusing both the anterior and 
posterior portion of the spine. All other cases in DRG 496 involve two 
separate surgical approaches used to reach the site of the spinal 
fusion. For these other patients, an incision is made into the patient, 
and a fusion is made in part of the spine. The patient is then turned 
over and a separate incision is made so that a fusion can be made in 
another part of the spine. The commenter added that these two separate 
incisions and fusions are more time consuming than the single incision 
used for code 81.61. The commenter also stated that patients receiving 
the two surgical approaches have a longer recovery period and use more 
hospital resources.
    We examined data in the MedPAR file for cases assigned to DRG 496 
and found the following:

----------------------------------------------------------------------------------------------------------------
                                                                                  Average length      Average
                               DRG                                     Count          of stay         charges
----------------------------------------------------------------------------------------------------------------

496--Cases with code 81.61......................................             829             4.7       50,659.69
496--Cases with code 81.61 with CC..............................             451             5.4       55,639.50
496--Cases with code 81.61 without CC...........................             378             3.8       44,718.16
496--Cases without 81.61........................................            1877             9.4       85,703.09
----------------------------------------------------------------------------------------------------------------


[[Page 28210]]

    We also examined cases in related DRG 497 (Spinal Fusion Except 
Cervical With CC) and DRG 498 (Spinal Fusion Except Cervical Without 
CC) in which code 81.61 was not reported. The chart below reflects our 
findings.

----------------------------------------------------------------------------------------------------------------
                                                                                  Average length      Average
                               DRG                                     Count          of stay         charges
----------------------------------------------------------------------------------------------------------------
497.............................................................          16,965            6.19      $49,315.27
498.............................................................          11,598            3.95       37,450.68
----------------------------------------------------------------------------------------------------------------

    These data clearly show that cases with code 81.61 have 
significantly less average charges than other cases in DRG 496 that 
have two surgical approaches. Cases with code 81.61 are more closely 
aligned with cases in DRG 497 and DRG 498. Furthermore, including code 
81.61 will have the effect of lowering the relative weights for DRG 496 
in future years. Therefore, we are proposing to remove code 81.61 from 
DRG 496 and reassign it to DRGs 497 and 498.
b. Multiple Level Spinal Fusion
    On October 1, 2003 (68 FR 45596), the following new ICD-9-CM 
procedure codes were created to identify the number of levels of 
vertebra fused during a spinal fusion procedure:

 81.62, Fusion or refusion of 2-3 vertebrae
 81.63, Fusion or refusion of 4-8 vertebrae
 81.64, Fusion or refusion of 9 or more vertebrae

    Prior to the creation of these new codes, we received a comment 
recommending the establishment of new DRGs that would differentiate 
between the number of levels of vertebrae involved in a spinal fusion 
procedure. In the August 1, 2003 final rule, we discussed the creation 
of these new codes and the lack of sufficient MedPAR data with the new 
multiple level spinal fusion codes (68 FR 45369). The commenter had 
conducted an analysis and submitted data to support redefining the 
spinal fusion DRGs. The analysis found that increasing the levels fused 
from 1 to 2 levels to 3 levels or more levels increased the mean 
standardized charges by 38 percent for lumbar/thoracic fusions, and by 
47 percent for cervical fusions.
    The following current spinal fusion DRGs separate cases based on 
whether or not a CC is present: DRG 497 (Spinal Fusion Except Cervical 
With CC) and DRG 498 (Spinal Fusion Except Cervical Without CC); DRG 
519 (Cervical Spinal Fusion With CC) and DRG 520 (Cervical Spinal 
Fusion Without CC). However, the difference in charges associated with 
the current CC split was only slightly greater than the difference 
attributable to the number of levels fused as found by the commenter's 
analysis. In addition, adopting the commenter's recommendation would 
have necessitated adjusting the DRG relative weights using non-MedPAR 
data because Medicare claims data with the new ICD-9-CM codes would not 
have been available until the FY 2003 MedPAR file. Therefore, at that 
time, we did not redefine the spinal fusion DRGs to differentiate on 
the basis of the number of levels of vertebrae involved in a spinal 
fusion procedure.
    We did not yet have any reported cases utilizing the new multilevel 
spinal fusion codes in our data. We stated that we would wait until 
sufficient data with the new multilevel spinal fusion codes were 
available before making a final determination on whether multilevel 
spinal fusions should be incorporated into the spinal fusion DRG 
structure. The codes went into effect on October 1, 2003 and we have 
not received any data using these codes. Spinal surgery is an area of 
rapid changes. In addition, we have created a series of new procedure 
codes that describe a new type of spinal surgery, spinal disc 
replacement. (See codes 84.60 through 84.69 in Table 6B in the Addendum 
to this proposed rule that will go into effect on October 1, 2004.) Our 
medical advisors describe this new surgical procedure as a more 
conservative approach for back pain than the spinal fusion surgical 
procedure. With only limited data concerning multiple level spinal 
fusion and the rapid changes in spinal surgery, we believe it is more 
prudent not to propose the establishment of new DRGs based on the 
number of levels of vertebrae involved in a spinal fusion procedure at 
this time.
    In addition, no other surgical DRG is split based on the number of 
procedures performed. For instance, the same DRG is assigned whether 
one or more angioplasties are performed on a patient's arteries. The 
insertion of multiple stents within an artery does not result in a 
different DRG assignment. Similarly, the excision of neoplasms from 
multiple sites does not lead to a different DRG assignment. To begin 
splitting DRGs based on the number of procedures performed or devices 
inserted could set a new and significant precedent for DRG policy. 
Therefore, while we will continue to study this area, we are not 
proposing to redefine the spinal fusion DRGs based on the number of 
levels of vertebrae fused at this time.
6. MDC 15 (Newborns and Other Neonates With Conditions Originating in 
the Perinatal Period)
    We continue to receive comments that MDC 15 (Newborn and Other 
Neonates With Conditions Originating in the Perinatal Period) does not 
adequately capture care provided for newborns and neonates by 
hospitals. The commenters point out that we have not updated the DRGs 
within MDC 15 as we have for other parts of the DRG system.
    Our primary focus of updates to the Medicare DRG classification 
system is on changes relating to the Medicare patient population, not 
the pediatric or neonatal patient populations. However, we acknowledge 
the Medicare DRGs are sometimes used to classify other patient 
populations. Over the years, we have received comments about aspects of 
the Medicare newborn DRGs that appear problematic, and we have 
responded to these on an individual basis. In the May 9, 2002 IPPS 
proposed rule (67 FR 31413), we proposed extensive changes to multiple 
DRGs within MDC 15. Because of our limited data and experience with 
newborn cases under Medicare, we contacted the National Association of 
Children's Hospitals and Related Institutions (NACHRI) to obtain 
proposals for possible revisions of the DRG categories within MDC 15. 
We received extensive comments opposing these revisions. Therefore, we 
did not implement the proposals.
    We advise those non-Medicare systems that need a more up-to-date 
system to choose from other systems that are currently in use in this 
country, or to develop their own modifications. As previously stated, 
we do not have the data or the expertise to develop more extensive 
newborn and pediatric DRGs. Our mission in maintaining the Medicare 
DRGs is to serve the Medicare population. Therefore, we will make only 
minor corrections of obvious errors to the DRGs within MDC 15. At this 
time, we do not plan to conduct a more extensive analysis involving 
major revisions to these DRGs.
    In the IPPS final rule for FY 2004 (68 FR 45360), we added heart 
failure

[[Page 28211]]

diagnosis codes 428.20 through 428.43 to the list of secondary 
diagnosis of major problem under DRG 387 (Prematurity With Major 
Problems) and DRG 389 (Full-Term Neonate With Major Problems). We 
received a comment after the August 1, 2003 final rule stating that we 
should add the following list of combination codes, which also include 
heart failure, to the list of major problems under DRGs 387 and 389:

 398.91, Rheumatic heart failure (congestive)
 402.01, Malignant hypertensive heart disease, with heart 
failure
 402.11, Benign hypertensive heart disease, with heart failure
 402.91, Unspecified hypertensive heart disease, with heart 
failure
 404.01, Malignant hypertensive heart and renal disease, with 
heart failure
 404.03, Malignant hypertensive heart and renal disease, with 
heart failure and renal failure
 404.11, Benign hypertensive heart and renal disease, with 
heart failure
 404.13, Benign hypertensive heart and renal disease, with 
heart failure and renal failure
 404.91, Unspecified hypertensive heart and renal disease, with 
heart failure
 404.93, Unspecified hypertensive heart and renal disease, with 
heart failure and renal failure.
 428.9, Heart failure, unspecified
    We agree that the codes listed above also include heart failure and 
should also be added to DRGs 387 and 389 as major problems. Therefore, 
we are proposing to add the heart failure codes listed above to DRGs 
387 and 389 as major problems.
7. MDC 20 (Alcohol/Drug Use and Alcohol/Drug Induced Organic Mental 
Disorders): Drug-Induced Dementia
    We received a request from a commenter that we remove the principal 
diagnosis code 292.82 (Drug-induced dementia) from MDC 20 (Alcohol/Drug 
Use and Alcohol/Drug Induced Organic Mental Disorders) and the 
following DRGs under MDC 20:

 DRG 521 (Alcohol/Drug Abuse or Dependence With CC)
 DRG 522 (Alcohol/Drug Abuse or Dependence With Rehabilitation 
Therapy Without CC)
 DRG 523 (Alcohol/Drug Abuse or Dependence Without 
Rehabilitation Therapy Without CC)
    The commenter indicated that a patient who has a drug-induced 
dementia should not be classified to an alcohol/drug DRG. However, the 
commenter did not propose a new DRG assignment for code 292.82.
    Our medical advisors have evaluated the request and determined that 
the most appropriate DRG classification for a patient with drug-induced 
dementia would be within MDC 20. The medical advisors indicated that 
because this mental condition is drug induced, it is appropriately 
classified to DRGs 521 through 523 in MDC 20. Therefore, we are not 
proposing a new DRG classification for the principal diagnosis code 
292.82.
8. MDC 22 (Burns): Burn Patients on Mechanical Ventilation
    We have received concerns raised by hospitals treating burn 
patients that the current DRG payment for burn patients on mechanical 
ventilation is not adequate. The DRG assignment for these cases depends 
on whether the hospital performed the tracheostomy or the tracheostomy 
was performed prior to transfer to the hospital. If the hospital does 
not actually perform the tracheostomy, the case is assigned to one of 
the burn DRGs in MDC 22 (Burns). If the hospital performs a 
tracheostomy, the case is assigned to Pre-MDC DRG 482 (Tracheostomy for 
Face, Mouth, and Neck Diagnoses) or DRG 483 (Tracheostomy With 
Mechanical Ventilation 96+ Hours or Principal Diagnosis Except Face, 
Mouth and Neck Diagnoses).
    In the August 1, 2002 final rule, we modified DRGs 482 and 483 to 
recognize code 96.72 (Continuous mechanical ventilation for 96+ hours) 
for the first time in the DRG assignment (67 FR 49996). The 
modification was partially in response to concerns that hospitals could 
omit diagnosis codes indicating face, mouth, or neck diagnoses in order 
to have cases assigned to DRG 483 rather than the much lower paying DRG 
482 (the payment for DRG 483 is more than four times greater than the 
DRG 482 payment weight). In addition, we noted that many patients 
assigned to DRG 483 did not have code 96.72 recorded. We believed this 
was due, in part, to the limited number of procedure codes (six) that 
can be submitted on the current billing form and the fact that code 
96.72 did not affect the DRG assignment prior to FY 2003. The 
modification was the first attempt to refine DRGs 482 and 483 so that 
patients who receive long-term mechanical ventilation for more than 96 
hours are differentiated from those who receive mechanical ventilation 
for less than 96 hours. The modification was intended to ensure that 
patients who have a tracheostomy and continuous mechanical ventilation 
greater than 96 hours (code 96.72) would be assigned to DRG 483. By 
making the GROUPER recognize long-term mechanical ventilation and 
assigning those patients to the higher weighted DRG 483, we encouraged 
hospitals to be more aware of the importance of reporting code 96.72 
and to increase reporting of code 96.72 when, in fact, patients had 
been on the mechanical ventilator for greater than 96 hours. We stated 
in the August 1, 2002 final rule that, once we received more accurate 
data, we would give consideration to further modifying DRGs 482 and 483 
based on the presence of code 96.72.
    To assess the DRG payments for burn patients on mechanical 
ventilation, we analyzed FY 2003 MedPAR data for burn cases in the 
following DRGs to determine the frequency for which these burn cases 
were treated with continuous mechanical ventilation for 96 or more 
consecutive hours (code 96.72):

 DRG 483 (Tracheostomy With Mechanical Ventilation 96+ Hours or 
Principal Diagnosis Except Face, Mouth, and Neck Diagnoses)
 DRG 504 (Extensive 3rd Degree Burns With Skin Graft)
 DRG 505 (Extensive 3rd Degree Burns Without Skin Graft)
 DRG 506 (Full Thickness Burn With Skin Graft or Inhalation 
Injury With CC or Significant Trauma)
 DRG 507 (Full Thickness Burn With Skin Graft or Inhalation 
Injury Without CC or Significant Trauma)
 DRG 508 (Full Thickness Burn Without Skin Graft or Inhalation 
Injury With CC or Significant Trauma)
 DRG 509 (Full Thickness Burn Without Skin Graft or Inhalation 
Injury Without CC or Significant Trauma)
 DRG 510 (Nonextensive Burns With CC or Significant Trauma)
 DRG 511 (Nonextensive Burns Without CC or Significant Trauma)

    The following chart summarizes those findings:

    We found 120 cases that reported code 96.72 within the 3,394 burn 
DRG cases (DRGs 504 through 511). Cases reporting code 96.72 have 
significantly longer average lengths of stay and average charges. The 
majority (54) of these cases that reported code 96.72 were in DRG 506. 
The cases with code 96.72 reported had average charges approximately 
1.5 times higher than other cases in DRG 506 without code 96.72.
    We noted that there were 21 cases that reported code 96.72 within 
DRG 510. Since the 21 patients were on continuous mechanical 
ventilation for 96 consecutive hours or more, it seems surprising that 
the principal diagnosis was listed as one of the nonextensive burn 
codes included in DRG 510. A closer review of these cases shows some 
questionable coding and reporting of information. It would appear that 
hospitals did not always correctly select the principal diagnosis (the 
reason after study that led to the hospital admission). For instance, 
one admission was for a second-degree burn of the ear. This patient was 
on a ventilator for over 96 hours. It would appear that the reason for 
the admission was a diagnosis other than the burn of the ear. Other 
cases where the patient received long-term mechanical ventilation 
included those with a principal diagnosis of first degree burn of the 
face, second degree burn of the nose, second degree burn of the lip, 
and an unspecified burn of the foot. These four cases reported average 
charges ranging from $48,551 to $186,824 and had lengths of stay 
ranging from 8 to 36 days.
    The impact of long-term mechanical ventilation is quite clear on 
burn cases as was shown by the data above. Therefore, we are proposing 
to modify the burn DRGs 504 through 509 under MDC 22 to recognize this 
impact. We are proposing to modify DRG 504 and DRG 505 so that code 
96.72 will be assigned to these DRGs when there is a principal 
diagnosis of extensive third degree burns or full thickness burns 
(those cases currently assigned to DRGs 504 through 509). In other 
words, when cases currently in DRGs 506 through 509 also have code 
96.72 reported, they would now be assigned to DRGs 504 or 505. We are 
proposing to modify the titles of DRGs 504 and 505 to reflect the 
proposed changes in reporting code 96.72 as follows:

 Proposed DRG 504 (Extensive Burns or Full Thickness Burns With 
Mechanical Ventilation 96+ Hours With Skin Graft)
 Proposed DRG 505 (Extensive Burns or Full Thickness Burns With 
Mechanical Ventilation 96+ Hours Without Skin Graft)

    Cases currently assigned to DRGs 504 and 505 that do not entail 96+ 
hours of mechanical ventilation will continue to be assigned to DRGs 
504 and 505 because they would have extensive burns, as required by the 
DRG logic.
    We are not proposing to include DRG 510 and DRG 511 within this 
revised DRG logic. Cases currently assigned to DRG 510 or DRG 511 that 
also report code 96.72 would not be reassigned to DRGs 504 and 505. We 
recommend that hospitals examine cases that are assigned to DRG 510 or 
DRG 511 and that have code 96.72 to determine if there are possible 
coding problems or other issues. As stated earlier, in examining 
reported cases within DRG 510, we noted several cases with code 96.72 
that appear to have an incorrect principal diagnosis. It would appear 
that the principal diagnosis may more appropriately be related to an 
inhalation injury, if the injury was present at the time of admission.
    We are specifically seeking comments on our proposal to move cases 
reporting code 96.72 from DRGs 506 through 509 and assign them to DRGs 
504 and 505. We also are seeking comments on our proposal not to 
include DRGs 510 and 511 in this proposed revision.
9. Pre-MDC: Tracheostomy
    In the August 1, 2002 IPPS final rule (67 FR 49996), for FY 2003, 
we modified DRG 482 (Tracheostomy for Face, Mouth, and Neck Diagnoses) 
and DRG 483 (Tracheostomy With Mechanical Ventilation 96+ Hours or 
Principal Diagnosis Except Face, Mouth, and Neck Diagnoses) to 
recognize procedure code 96.72 (Continuous mechanical ventilation 96+ 
hours) in the DRG 483 assignment. As discussed earlier, we were 
concerned about an underreporting of code 96.72 and wanted to encourage 
increased reporting of this code.
    We examined cases in the MedPAR file in which code 96.72 was 
reported

within DRGs 482 and 483. The following chart illustrates the average 
charges and lengths of stays for cases within DRGs 482 and 483 with and 
without code 96.72 reported:

    Of the 3,557 cases reported in DRG 482, only 22 cases reported code 
96.72. These 22 cases did not have a tracheostomy performed. All 22 
cases reported code 30.4 (Laryngectomy), which also leads to an 
assignment of DRG 482. It would appear that the long-term mechanical 
ventilation was performed through an endotracheal tube instead of 
through a tracheostomy. While the average charges for DRG 482 cases 
with code 96.72 reported were significantly higher than the average 
charges for other cases in the DRG, we do not believe that the very 
limited number of cases (22) warrants proposing a DRG modification. 
Therefore, we are not proposing any modification for DRG 482 at this 
time. We will continue to monitor cases assigned to this DRG.
    In DRG 483, 19,669 cases were reported with code 96.72. However, 
the data were counter-intuitive. While one would expect to find higher 
average charges for cases reported with code 96.72, the opposite is the 
case. Cases in DRG 483 reported with code 96.72 had average charges 
that were $40,623 lower than those not reported with code 96.72. 
Clearly, the presence or absence of code 96.72 does not explain 
differences in charges for patients within DRG 483.
    As stated earlier, we are concerned that hospitals may not always 
report code 96.72 because of space limitations. The electronic billing 
system limits the number of procedure codes that can be reported to six 
codes. We then looked at whether or not another major O.R. procedure is 
performed in addition to a tracheostomy. The DRG 483 logic requires 
that all patients assigned to DRG 483 have a tracheostomy. We examined 
cases in DRG 483 in the MedPAR file and discovered that those patients 
in DRG 483 who have a major procedure performed in addition to the 
tracheostomy have higher charges. A major procedure is a procedure 
whose code is included on the list that would be assigned to DRG 468 
(Extensive O.R. Procedure Unrelated to Principal Diagnosis), except for 
tracheostomy codes 31.21 and 31.29. Currently, this additional O.R. 
procedure does not affect the DRG assignment for cases assigned to DRG 
483. The following chart reflects our findings.

                               DRG                                     Count          of stay         Charges

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

    We found that cases of patients assigned to DRG 483 who had a major 
procedure (in addition to the required tracheostomy) had average 
charges that were $87,023 higher than the average charges for cases 
without a major O.R. procedure and an average length of stay of 5 days 
more than those without a major O.R. procedure. We found that the 
performance of an additional major O.R. procedure helps to identify the 
more expensive patients within DRG 483.
    Therefore, as a result of our findings, we are proposing to modify 
DRG 483 by dividing these cases into two new DRGs depending on whether 
or not there is a major O.R. procedure reported (in addition to the 
tracheostomy). We are proposing to delete DRG 483 and create two new 
DRGs as follows:

 Proposed new DRG 541 (Tracheostomy With Mechanical Ventilation 
96+ Hours or Principal Diagnosis Except Face, Mouth, and Neck Diagnoses 
With Major O.R. Procedure)
 Proposed new DRG 542 (Tracheostomy With Mechanical Ventilation 
96+ Hours or Principal Diagnosis Except Face, Mouth and Neck Diagnoses 
Without Major O.R. Procedure)

    We are specifically seeking comments on our proposal to delete DRG 
483 and replace it with two proposed new DRGs by splitting the 
assignment of cases on the basis
