00954ZZ ICD-10-PCS Code: Drainage of Intracranial Subarachnoid Space, Percutaneous Endoscopic Approach
Drainage of Cran Subrac Spc, 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 Operation9 | Drainage Taking or letting out fluids and/or gases from a body part |
| 4 | Body Part5 | Subarachnoid Space, Intracranial |
| 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 5 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
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
