About 05WY02Z

05WY02Z is the ICD-10-PCS code for a revision procedure on the upper vein using an open 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, upper limb vessels, the ICD-9-CM procedure title it maps to (38.03).

For a different body part, codes include 05W002Z (azygos vein).

The same procedure with a different approach is coded 05WY32Z (percutaneous), 05WY42Z (percutaneous endoscopic) and 05WYX2Z (external).

With a different device, use 05WY00Z (drainage device), 05WY03Z (infusion device), 05WY07Z (autologous tissue substitute), 05WY0CZ (extraluminal device), 05WY0DZ (intraluminal device), 05WY0JZ (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.
