00C70ZZ ICD-10-PCS Code: Extirpation of Matter from Cerebral Hemisphere, Open Approach
Extirpation of Matter from Cereb Hemis, 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 System0 | Central Nervous System and Cranial Nerves |
| 3 | Root OperationC | Extirpation Taking or cutting out solid matter from a body part |
| 4 | Body Part7 | Cerebral Hemisphere |
| 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 9 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 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
- MDC 24 — Craniotomy for Multiple Significant Trauma: DRG 955
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
