MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 11 MS-DRGs:

  • MDC 01 — Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis: DRG 023, DRG 024
  • MDC 01 — Craniotomy and endovascular intracranial procedures: DRG 025, DRG 026, DRG 027
  • MDC 08 — Biopsies of Musculoskeletal System and Connective Tissue: DRG 477, DRG 478, DRG 479
  • MDC 10 — Other Endocrine, Nutritional and Metabolic O.R. Procedures: DRG 628, DRG 629, DRG 630

From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
