About 00P640Z

00P640Z is the ICD-10-PCS code for a removal procedure on the cerebral ventricle using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, removal means taking out or off a device 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 00P040Z (brain), 00PE40Z (cranial nerve), 00PU40Z (spinal canal) and 00PV40Z (spinal cord).

The same procedure with a different approach is coded 00P600Z (open), 00P630Z (percutaneous) and 00P6X0Z (external).

With a different device, use 00P642Z (monitoring device), 00P643Z (infusion device), 00P64JZ (synthetic substitute), 00P64MZ (neurostimulator lead) and 00P64YZ (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.
