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 03 — Other Ear, Nose, Mouth and Throat O.R. Procedures: DRG 143, DRG 144, DRG 145
- MDC 04 — Other Respiratory System O.R. Procedures: DRG 166, DRG 167, DRG 168
- 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.
