MS-DRG Grouper Relationships (FY2027)

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 9 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 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
  • MDC 24 — Craniotomy for Multiple Significant Trauma: DRG 955

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