About 05W042Z

05W042Z is the ICD-10-PCS code for a revision procedure on the azygos vein using a percutaneous endoscopic approach with monitoring 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 incision of vessel, other thoracic vessels, the ICD-9-CM procedure title it maps to (38.05).

For a different body part, codes include 05WY42Z (upper vein).

The same procedure with a different approach is coded 05W002Z (open), 05W032Z (percutaneous) and 05W0X2Z (external).

With a different device, use 05W04MZ (neurostimulator lead).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It was added in FY2017, effective October 1, 2016.
