MS-DRG 031Surgical
Ventricular Shunt Procedures with MCC
Major Diagnostic Category 01·Grouped by procedure·FY 2027
MS-DRG 031 is a Surgical Medicare Severity Diagnosis Related Group under Major Diagnostic Category 01 (MDC 01) with a Major Complication or Comorbidity (MCC). For FY 2027 it carries a relative weight of 4.2720 with a geometric mean length of stay of 6.5 days and an arithmetic mean of 9.9 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:
- 4.2720 (payment multiplier vs. the average case (1.0))
- Geometric mean stay:
- 6.5 days (used for transfer payments)
- Average stay:
- 9.9 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.
