MS-DRG 429Surgical
Combined Anterior and Posterior Cervical Spinal Fusion with MCC
Major Diagnostic Category 08·Grouped by procedure·FY 2027
MS-DRG 429 is a Surgical Medicare Severity Diagnosis Related Group under Major Diagnostic Category 08 (MDC 08) with a Major Complication or Comorbidity (MCC). For FY 2027 it carries a relative weight of 8.8363 with a geometric mean length of stay of 9.5 days and an arithmetic mean of 12 days. Hospitals use this grouping to determine reimbursement for inpatient stays under Medicare.

FY 2027 payment data
From Table 5 of the FY 2027 IPPS Final Rule (CMS).
- Relative weight:
- 8.8363 (payment multiplier vs. the average case (1.0))
- Geometric mean stay:
- 9.5 days (used for transfer payments)
- Average stay:
- 12 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 |
|---|---|---|---|
| 429 | Combined Anterior and Posterior Cervical Spinal Fusion with MCC (this page) | 8.8363 | 9.5 days |
| 430 | Combined Anterior and Posterior Cervical Spinal Fusion without MCC | 5.8956 | 3.5 days |
