MS-DRG 582Surgical
Mastectomy for Malignancy with CC/MCC
Major Diagnostic Category 09·Grouped by procedure·FY 2027
MS-DRG 582 is a Surgical Medicare Severity Diagnosis Related Group under Major Diagnostic Category 09 (MDC 09) with a Complication or Comorbidity (CC). It maps to 74 ICD-10-CM diagnosis codes. For FY 2027 it carries a relative weight of 1.8006 with a geometric mean length of stay of 2.1 days and an arithmetic mean of 2.8 days.

FY 2027 payment data
From Table 5 of the FY 2027 IPPS Final Rule (CMS).
- Relative weight:
- 1.8006 (payment multiplier vs. the average case (1.0))
- Geometric mean stay:
- 2.1 days (used for transfer payments)
- Average stay:
- 2.8 days (arithmetic mean)
- Post-acute transfer policy:
- No (not subject to it)
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 |
|---|---|---|---|
| 582 | Mastectomy for Malignancy with CC/MCC (this page) | 1.8006 | 2.1 days |
| 583 | Mastectomy for Malignancy without CC/MCC | 1.8006 | 2.1 days |
