Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 8 MS-DRGs:

MDC 08 — Major Shoulder or Elbow Joint Procedures: DRG 507, DRG 508
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.
