Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 12 MS-DRGs:
- MDC 01 — Extracranial Procedures: DRG 037, DRG 038, DRG 039
- MDC 05 — Other Major Cardiovascular Procedures: DRG 270, DRG 271, DRG 272
- MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
- MDC 24 — Other O.R. Procedures for Multiple Significant Trauma: DRG 957, DRG 958, DRG 959
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
