About 00930ZZ

00930ZZ is the ICD-10-PCS code for a drainage procedure on the epidural space, intracranial using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases 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 00900ZZ (brain), 00910ZZ (cerebral meninges), 00920ZZ (dura mater), 00940ZZ (subdural space, intracranial), 00950ZZ (subarachnoid space, intracranial), 00960ZZ (cerebral ventricle) and 24 more.

The same procedure with a different approach is coded 00933ZZ (percutaneous) and 00934ZZ (percutaneous endoscopic).

With a different device, use 009300Z (drainage device).

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. Procedures for Injuries” and 1 more.

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