About 00H63YZ

00H63YZ is the ICD-10-PCS code for a insertion procedure on the cerebral ventricle using a percutaneous approach with other device. 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 other incision of brain, the ICD-9-CM procedure title it maps to (01.39).

For a different body part, codes include 00H03YZ (brain), 00HE3YZ (cranial nerve), 00HU3YZ (spinal canal) and 00HV3YZ (spinal cord).

The same procedure with a different approach is coded 00H60YZ (open) and 00H64YZ (percutaneous endoscopic).

With a different device, use 00H631Z (radioactive element), 00H632Z (monitoring device), 00H633Z (infusion device) and 00H63MZ (neurostimulator lead).

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 was added in FY2018, effective October 1, 2017.
