| 2 | Body System0 | Central Nervous System and Cranial Nerves |
| 3 | Root Operation9 | Drainage Taking or letting out fluids and/or gases from a body part |
| 4 | Body PartP | Glossopharyngeal Nerve |
| 5 | Approach0 | Open |
| 6 | DeviceZ | No Device |
| 7 | QualifierX | Diagnostic |
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 15 MS-DRGs:
- MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
- MDC 03 — Other Ear, Nose, Mouth and Throat O.R. Procedures: DRG 143, DRG 144, DRG 145
- MDC 08 — Other Musculoskeletal System and Connective Tissue O.R. Procedures: DRG 515, DRG 516, DRG 517
- 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.
