01BK0ZZ ICD-10-PCS Code: Excision of Head and Neck Sympathetic Nerve, Open Approach
Axis Breakdown
Every ICD-10-PCS code is exactly seven characters, one per axis. Each character's meaning is defined by its position in the code.
| Position | Value | Meaning |
|---|---|---|
| 1 | Section0 | Medical and Surgical |
| 2 | Body System1 | Peripheral Nervous System |
| 3 | Root OperationB | Excision Cutting out or off, without replacement, a portion of a body part |
| 4 | Body PartK | Head and Neck Sympathetic Nerve |
| 5 | Approach0 | Open |
| 6 | DeviceZ | No Device |
| 7 | QualifierZ | No Qualifier |
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 7 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 05 — Other Circulatory System O.R. Procedures: DRG 264
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
