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 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
  • MDC 08 — Hand or Wrist Procedures, Except Major Thumb or Joint Procedures: DRG 513, DRG 514
  • MDC 21 — Hand Procedures for Injuries: DRG 906
  • 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.
