About 00W63YZ

00W63YZ is the ICD-10-PCS code for a revision procedure on the cerebral ventricle using a percutaneous approach with other device. 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 00W03YZ (brain), 00WE3YZ (cranial nerve), 00WU3YZ (spinal canal) and 00WV3YZ (spinal cord).

The same procedure with a different approach is coded 00W60YZ (open) and 00W64YZ (percutaneous endoscopic).

With a different device, use 00W630Z (drainage device), 00W632Z (monitoring device), 00W633Z (infusion device), 00W63JZ (synthetic substitute) and 00W63MZ (neurostimulator lead).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
