Insertion of Neuro Lead into Cereb Vent, Perc Endo 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 Part6 | Cerebral Ventricle |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | DeviceM | Neurostimulator Lead |
| 7 | QualifierZ | No Qualifier |
Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 17 MS-DRGs:
- MDC 01 — Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis: DRG 023, DRG 024
- MDC 01 — Craniotomy and endovascular intracranial procedures: DRG 025, DRG 026, DRG 027
- MDC 17 — Lymphoma and Leukemia with Major O.R. Procedures: DRG 820, DRG 821, DRG 822
- MDC 17 — Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures: DRG 826, DRG 827, DRG 828
- 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.
