About 03WY4KZ

03WY4KZ is the ICD-10-PCS code for a revision procedure on the upper artery using a percutaneous endoscopic approach with nonautologous tissue substitute. 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, unspecified site, the ICD-9-CM procedure title it maps to (38.00).

The same procedure with a different approach is coded 03WY0KZ (open), 03WY3KZ (percutaneous) and 03WYXKZ (external).

With a different device, use 03WY40Z (drainage device), 03WY42Z (monitoring device), 03WY43Z (infusion device), 03WY47Z (autologous tissue substitute), 03WY4CZ (extraluminal device), 03WY4DZ (intraluminal device) and 3 more.

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