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 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
• MDC 05 — Cardiac Pacemaker Revision Except Device Replacement: DRG 260, DRG 261, DRG 262
• 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.
