About 00WU4YZ

00WU4YZ is the ICD-10-PCS code for a revision procedure on the spinal canal using a percutaneous endoscopic 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 operations on spinal cord and spinal canal structures, the ICD-9-CM procedure title it maps to (03.99).

For a different body part, codes include 00W04YZ (brain), 00W64YZ (cerebral ventricle), 00WE4YZ (cranial nerve) and 00WV4YZ (spinal cord).

The same procedure with a different approach is coded 00WU0YZ (open) and 00WU3YZ (percutaneous).

With a different device, use 00WU40Z (drainage device), 00WU42Z (monitoring device), 00WU43Z (infusion device), 00WU4JZ (synthetic substitute) and 00WU4MZ (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.
