009C0ZXDrainage of Cerebellum, Open Approach, Diagnostic

009C0ZX is the ICD-10-PCS code for a drainage procedure on the cerebellum using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of brain, the ICD-9-CM procedure title it maps to (01.14).

For a different body part, codes include 00900ZX (brain), 00910ZX (cerebral meninges), 00920ZX (dura mater), 00930ZX (epidural space, intracranial), 00940ZX (subdural space, intracranial), 00950ZX (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 009C3ZX (percutaneous) and 009C4ZX (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC), DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), DRG 026 (Craniotomy and Endovascular Intracranial Procedures with CC), DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC) and DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
