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, is that the TRICARE DRG-based payment system is modeled on the Medicare PPS, and that, whenever practicable, the TRICARE system will follow the same rules that apply to the Medicare PPS. The Centers for Medicare and Medicaid Services (CMS) 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 DRG-Based Payment System
Following is a discussion of the changes CMS has made to the Medicare PPS that affect the TRICARE DRG-based payment system.
A. DRG Classifications
Under both the Medicare PPS and the TRICARE 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 DRG-based payment system is the same as the current Medicare Grouper with two modifications. The TRICARE 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 For admissions occurring on or after October 1, 2001, DRG 435 has been replaced by DRG 523. The TRICARE system has replaced DRG 523 with the two age-based DRGs (900 and 901). 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 Start Printed Page 61435assignment of the PreMDC DRGs. This resulted in all neonate tracheostomies and organ transplants 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 admissions occurring on or after October 1, 2001, DRGs 512 and 513 were added to the PreMDC DRGs, between DRGs 480 and 103 in the TRICARE grouper hierarchy logic. For admissions occurring on or after October 1, 2004, DRG 483 was deleted and replaced with DRGs 541 and 542, splitting the assignment of cases on the basis of the performance of a major operating room procedure. The description for DRG 480 was changed to “Liver Transplant and/or Intestinal Transplant”, and the description for DRG 103 was changed to “Heart/Heart Lung Transplant or Implant of Heart Assist System”. For FY 2006, CMS will implement classification changes, including surgical hierarchy changes. The TRICARE Grouper will incorporate all changes made to the Medicare Grouper.
B. Wage Index and Medicare Geographic Classification Review Board Guidelines
TRICARE will continue to use the same wage index amounts used for the Medicare PPS. TRICARE will also duplicate all changes with regard to the wage index for specific hospitals that are redesignated by the Medicare Geographic Classification Review Board. In addition, TRICARE will continue to utilize the out commuting wage index adjustment.
C. Revision of the Labor-Related Share of the Wage Index
TRICARE is adopting CMS' percentage of labor related share of the standardized amount. For wage index values greater than 1.0, the labor-related portion of the ASA shall equal 69.7 percent. For wage index values less than or equal to 1.0 the labor-related portion of the ASA shall continue to equal 62 percent.
D. Hospital Market Basket
TRICARE will update the adjusted standardized amounts according to the final updated hospital market basket used for the Medicare PPS for all hospitals subject to the TRICARE DRG-based payment system according to CMS's August 12, 2005, final rule.
E. Outlier Payments
Since TRICARE does not include capital payments in our DRG-based payments (TRICARE reimburses hospitals for their capital costs as reported annually to the contractor on a pass through basis), we will use the fixed loss cost outlier threshold calculated by CMS for paying cost outliers in the absence of capital prospective payments. For FY 2006, 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 2006, in order for a case to qualify for cost outlier payments, the costs must exceed the TRICARE DRG base payment rate (wage adjusted) for the DRG plus the IDME payment plus $21,783 (wage adjusted). The marginal cost factor for cost outliers continues to be 80 percent.
F. National Operating Standard Cost as a Share of Total Costs
The FY 2006 TRICARE National Operating Standard Cost as a Share of Total Costs (NOSCASTC) used in calculating the cost outlier threshold is 0.923. TRICARE uses the same methodology as CMS for calculating the NOSCASTC however, the variables are different because TRICARE uses national cost to charge ratios while CMS uses hospital specific cost to charge ratios.
G. Indirect Medical Education (IDME) Adjustment
Passage of the MMA of 2003 modified the formula multipliers to be used in the calculation of the indirect medical education IDME adjustment factor. Since the IDME formula used by TRICARE does not include disproportionate share hospitals (DSHs), the variables in the formula are different than Medicare's however; the percentage reductions that will be applied to Medicare's formula will also be applied to the TRICARE IDME formula. The new multiplier for the IDME adjustment factor for TRICARE for FY 2006 is 1.04.
H. Expansion of the Post Acute Care Transfer Policy
For FY 2006 TRICARE is adopting CMS' expanded post acute care transfer policy according to CMS' final rule published August 12, 2005.
I. Blood Clotting Factor
For FY 2006, TRICARE is adopting CMS' payment methodology for blood clotting factor according to CMS' final rule published August 12, 2005.
II. Cost to Charge Ratio
While CMS uses hospital-specific cost to charge ratios, TRICARE uses a national cost to charge ratio. For FY 2006, the cost-to-charge ratio used for the TRICARE DRG-based payment system will be 0.4060, which is increased to 0.4130 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 0.4468. For FY 2006, the neonatal cost-to-charge ratio of .64 is being reduced to the same cost-to-charge ratio of .4130 for acute care hospitals.
III. Updated Rates and Weights
The updated rates and weights are accessible through the Internet at http://www.tricare.osd.mil under the sequential headings TRICARE Provider Information, Rates and Reimbursements, and DRG Information. Table 1 provides the ASA rates and Table 2 provides the DRG weights to be used under the TRICARE DRG-based payment system during FY 2006 and which is a result of the changes described above. The implementing regulations for the TRICARE/CHAMPUS DRG-based payment system are in 32 CFR Part 199.Start Signature
