Insertion of Neurostimulator Lead into Cranial Nerve, Percutaneous Approach
Insertion of Neuro Lead into Cranial Nrv, Perc 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 System0 | Central Nervous System and Cranial Nerves |
| 3 | Root OperationH | Insertion Putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part |
| 4 | Body PartE | Cranial Nerve |
| 5 | Approach3 | Percutaneous |
| 6 | DeviceM | Neurostimulator Lead |
| 7 | QualifierZ | No Qualifier |
Potential MS-DRG Relationships (FY2026)

- MDC 03 — Other Ear, Nose, Mouth and Throat O.R. Procedures: DRG 143, DRG 144, DRG 145
- MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254
- MDC 08 — Other Musculoskeletal System and Connective Tissue O.R. Procedures: DRG 515, DRG 516, DRG 517
- MDC 11 — Other Kidney and Urinary Tract Procedures: DRG 673, DRG 674, DRG 675
- MDC 12 — Other Male Reproductive System O.R. Procedures: DRG 715, DRG 716, DRG 717, DRG 718
- MDC 13 — Other Female Reproductive System O.R. Procedures: DRG 749, DRG 750
- 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.
