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 2 MS-DRGs:

  • MDC 08 — Major Thumb or Joint Procedures: DRG 506
  • MDC 21 — Hand Procedures for Injuries: DRG 906

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