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 08 — Foot Procedures: DRG 503, DRG 504, DRG 505
- 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.
