About 00W6XMZ

00W6XMZ is the ICD-10-PCS code for a revision procedure on the cerebral ventricle using an external 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 00W0XMZ (brain), 00WEXMZ (cranial nerve), 00WUXMZ (spinal canal) and 00WVXMZ (spinal cord).

The same procedure with a different approach is coded 00W60MZ (open), 00W63MZ (percutaneous) and 00W64MZ (percutaneous endoscopic).

With a different device, use 00W6X0Z (drainage device), 00W6X2Z (monitoring device), 00W6X3Z (infusion device) and 00W6XJZ (synthetic substitute).

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

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