SUPPLEMENTARY INFORMATION:

The final rule published on September 1, 1987 (52 FR 32992) set forth the basic procedures used under the CHAMPUS DRG-based payment system. This was subsequently amended by final rules published August 31, 1988 (53 FR 33461), October 21, 1988 (53 FR 41331), December 16, 1988 (53 FR 50515), May 30, 1990 (55 FR 21863), October 22, 1990 (55 FR 42560), and September 10, 1998 (63 FR 48439).

An explicit tenet of these final rules, and one based on the statute authorizing the use of DRGs by TRICARE/CHAMPUS, is that the TRICARE/CHAMPUS DRG-based payment system is modeled on the Medicare PPS, and that, whenever practicable, the TRICARE/CHAMPUS system will follow the same rules that apply to the Medicare PPS. HCFA publishes these changes annually in the Federal Register and discusses in detail the impact of the changes.

In addition, this notice updates the rates and weights in accordance with our previous final rules. The actual changes we are making, along with a description of their relationship to the Medicare PPS, are detailed below.

I. Medicare PPS Changes Which Affect the TRICARE/CHAMPUS DRG-Based Payment System

Following is a discussion of the changes the Health Care Financing Administration (HCFA) has made to the Medicare PPS that affect the TRICARE/CHAMPUS DRG-based payment system.

A. DRG Classifications

Under both the Medicare PPS and the TRICARE/CHAMPUS DRG-based payment system, cases are classified into the appropriate DRG by a Grouper program. The Grouper classifies each case into a DRG on the basis of the diagnosis and procedure codes and demographic information (that is, sex, age, and discharge status). The Grouper used for the TRICARE/CHAMPUS DRG-based payment system is the same as the current Medicare Grouper with two modifications. The TRICARE/CHAMPUS system has replaced Medicare DRG 435 with two age-based DRGs (900 and 901), and has implemented thirty-four (34) neonatal DRGs in place of Medicare DRGs 385 through 390. For admissions occurring on or after October 1, 1995, the CHAMPUS grouper hierarchy logic was changed so the age split (age <29 days) and assignments to MDC 15 occur before assignment of the PreMDC DRGs. This resulted in all neonate tracheostomies and organ tranplants to be grouped to MDC 15 and not to DRGs 480-483 or 495. For admissions occurring on or after October 1, 1998, the CHAMPUS grouper hierarchy logic was changed to move DRG 103 to the PreMDC DRGs and to assign patients to PreMDC DRGs 480, 103 and 495 before assignment to MDC 15 DRGs and the neonatal DRGs.

For FY 2001, HCFA will implement classification changes, including surgical hierarchy changes. The CHAMPUS Grouper will incorporate all changes made to the Medicare Grouper.

B. Wage Index and Medicare Geographic Classification Review Board Guidelines

TRICARE/CHAMPUS will continue to use the same wage index amounts used for the Medicare PPS. In addition, TRICARE/CHAMPUS will duplicate all changes with regard to the wage index for specific hospitals that are redesignated by the Medicare Geographic Classification Review Board.

C. Hospital Market Basket

TRICARE/CHAMPUS will update the adjusted standardized amounts according to the final updated hospital market basket used for the Medicare PPS according to HCFA's August 1, 2000, final rule.

D. Outlier Payments

Since TRICARE/CHAMPUS does not include capital payments in our DRG-based payments, we will use the fixed loss cost outlier threshold calculated by HFCA for paying cost outliers in the absence of capital prospective payments. For FY 2001, the fixed loss cost outlier threshold is based on the sum of the applicable DRG-based payment rate plus any amounts payable for IDME plus a fixed dollar amount. Thus, for FY 2001, in order for a case to qualify for cost outlier payments, the costs must exceed the TRICARE/CHAMPUS DRG base payment rate (wage adjusted) for the DRG plus the IDME payment plus $16,036 (wage adjusted). The marginal cost factor for cost outliers continues to be 80 percent.

E. Blood Clotting Factor

For FY 2001, TRICARE/CHAMPUS will use the following HCPCS codes and payment rates for blood clotting factors:

J7190 Factor VIII (antihemophilic factor—human): $0.85 per unit

J7191 Factor VIII (antihemophilic factor—porcine): 2.09 per unit

J7192 Factor VIII (antihemophilic factor—recombinant): 1.12 per unit

J7194 Factor IX (complex): 0.31 per unit

J7198 Anti-inhibitor: 1.43 per unit

Q0160 Factor IX (antihemophilic factor, purified, Non-recombinant): 1.05 per unit

Q0161 Factor IX (antihemophilic factor, recombinant): 1.12 per unit

F. Indirect Medical Education (IDME) Adjustment

The Balanced Budget Refinement Act of 1999, modified the transition for the IDME adjustment that was established by the Balanced Budget Act of 1997. The new multiplier for the IDME adjustment factor for TRICARE/CHAMPUS for FY 2001 is 1.16.

II. Cost to Charge Ratio

For FY 2001, the cost-to-charge ratio used for the TRICARE/CHAMPUS DRG-based payment system will be 0.5353, which is increased to 0.5408 to account for bad debts. This shall be used to calculate the adjusted standardized amounts and to calculate cost outlier payments, except for children's hospitals. For children's hospital cost outliers, the cost-to-charge ratio used is 0.5913.

III. Updated Rates and Weights

The updated rates and weights are accessible through the Internet at www.tricare.osd.mil under the heading TRICARE Provider Information. Table 1 provides the ASA rates and Table 2 provides the DRG weights to be used under the TRICARE/CHAMPUS DRG-based payment system during FY 2001 and which is a result of the changes described above. The implementing regulations for the TRICARE/CHAMPUS DRUG-based payment system are in 32 CFR part 199.
