FY 2027 payment data
From Table 5 of the FY 2027 IPPS Final Rule (CMS).
- Relative weight:
- 4.6889 (payment multiplier vs. the average case (1.0))
- Geometric mean stay:
- 3.4 days (used for transfer payments)
- Average stay:
- 4.2 days (arithmetic mean)
- Post-acute transfer policy:
- Yes (early transfers can be paid less)
Same condition, other severity levels
CMS splits one condition into separate DRGs by how sick the patient is. With MCC pays more than with CC, which pays more than without CC/MCC.
| DRG | Title | Relative weight | Mean stay |
|---|---|---|---|
| 276 | Cardiac Defibrillator Implant with MCC or Carotid Sinus Neurostimulator | 6.2034 | 6.3 days |
| 277 | Cardiac Defibrillator Implant without MCC (this page) | 4.6889 | 3.4 days |
