01NG4ZZ ICD-10-PCS Code: Release Tibial Nerve, Percutaneous Endoscopic 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 OperationN | Release Freeing a body part from an abnormal physical constraint by cutting or by the use of force |
| 4 | Body PartG | Tibial Nerve |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | DeviceZ | No Device |
| 7 | QualifierZ | No Qualifier |
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 12 MS-DRGs:
- MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
- MDC 08 — Foot Procedures: DRG 503, DRG 504, DRG 505
- 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.
