About 00CD4ZZ

00CD4ZZ is the ICD-10-PCS code for a extirpation procedure on the medulla oblongata using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other incision of brain, the ICD-9-CM procedure title it maps to (01.39).

For a different body part, codes include 00C04ZZ (brain), 00C14ZZ (cerebral meninges), 00C24ZZ (dura mater), 00C34ZZ (epidural space, intracranial), 00C44ZZ (subdural space, intracranial), 00C54ZZ (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 00CD0ZZ (open) and 00CD3ZZ (percutaneous).

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 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Other O.R.
