About 05W0XMZ

05W0XMZ is the ICD-10-PCS code for a revision procedure on the azygos vein 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 05W3XMZ (right innominate vein) and 05W4XMZ (left innominate vein).

The same procedure with a different approach is coded 05W00MZ (open), 05W03MZ (percutaneous) and 05W04MZ (percutaneous endoscopic).

With a different device, use 05W0X2Z (monitoring device).

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 FY2017, effective October 1, 2016.
