About 02WY02Z

02WY02Z is the ICD-10-PCS code for a revision procedure on the great vessel 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, other thoracic vessels, the ICD-9-CM procedure title it maps to (38.05).

For a different body part, codes include 02WA02Z (heart).

The same procedure with a different approach is coded 02WY32Z (percutaneous), 02WY42Z (percutaneous endoscopic) and 02WYX2Z (external).

With a different device, use 02WY03Z (infusion device), 02WY07Z (autologous tissue substitute), 02WY08Z (zooplastic tissue), 02WY0CZ (extraluminal device), 02WY0DZ (intraluminal device), 02WY0JZ (synthetic substitute) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.

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