About 00H63MZ

00H63MZ is the ICD-10-PCS code for a insertion procedure on the cerebral ventricle using a percutaneous approach with neurostimulator lead. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to implantation or replacement of intracranial neurostimulator lead(s), the ICD-9-CM procedure title it maps to (02.93).

For a different body part, codes include 00H03MZ (brain), 00HE3MZ (cranial nerve), 00HU3MZ (spinal canal) and 00HV3MZ (spinal cord).

The same procedure with a different approach is coded 00H60MZ (open) and 00H64MZ (percutaneous endoscopic).

With a different device, use 00H631Z (radioactive element), 00H632Z (monitoring device), 00H633Z (infusion device) and 00H63YZ (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 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 3 more.

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