About 00W63MZ
00W63MZ is the ICD-10-PCS code for a revision procedure on the cerebral ventricle using a percutaneous approach with neurostimulator lead. 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 incision of brain, the ICD-9-CM procedure title it maps to (01.39).
For a different body part, codes include 00W03MZ (brain), 00WE3MZ (cranial nerve), 00WU3MZ (spinal canal) and 00WV3MZ (spinal cord).
The same procedure with a different approach is coded 00W60MZ (open), 00W64MZ (percutaneous endoscopic) and 00W6XMZ (external).
With a different device, use 00W630Z (drainage device), 00W632Z (monitoring device), 00W633Z (infusion device), 00W63JZ (synthetic substitute) and 00W63YZ (other 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.
