About 04WY07Z

04WY07Z is the ICD-10-PCS code for a revision procedure on the lower artery using an open approach with autologous 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 04WY37Z (percutaneous), 04WY47Z (percutaneous endoscopic) and 04WYX7Z (external).

With a different device, use 04WY00Z (drainage device), 04WY02Z (monitoring device), 04WY03Z (infusion device), 04WY0CZ (extraluminal device), 04WY0DZ (intraluminal device), 04WY0JZ (synthetic substitute) and 2 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.
