About 00W00KZ

00W00KZ is the ICD-10-PCS code for a revision procedure on the brain using an open approach with nonautologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other craniotomy, the ICD-9-CM procedure title it maps to (01.24).

For a different body part, codes include 00W20KZ (dura mater), 00WT0KZ (spinal meninges) and 00WV0KZ (spinal cord).

The same procedure with a different approach is coded 00W03KZ (percutaneous), 00W04KZ (percutaneous endoscopic) and 00W0XKZ (external).

With a different device, use 00W000Z (drainage device), 00W002Z (monitoring device), 00W003Z (infusion device), 00W007Z (autologous tissue substitute), 00W00JZ (synthetic substitute), 00W00MZ (neurostimulator lead) and 1 more.

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) and DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis” and “Craniotomy and endovascular intracranial procedures”.

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