About 02US4KZ

02US4KZ is the ICD-10-PCS code for a supplement procedure on the right pulmonary vein using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to repair of blood vessel with tissue patch graft, the ICD-9-CM procedure title it maps to (39.56).

For a different body part, codes include 02U04KZ (coronary artery, one artery), 02U14KZ (coronary artery, two arteries), 02U24KZ (coronary artery, three arteries), 02U34KZ (coronary artery, four or more arteries), 02U54KZ (atrial septum), 02U64KZ (right atrium) and 19 more.

The same procedure with a different approach is coded 02US0KZ (open) and 02US3KZ (percutaneous).

With a different device, use 02US47Z (autologous tissue substitute), 02US48Z (zooplastic tissue) and 02US4JZ (synthetic substitute).

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), DRG 254 (Other Vascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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