About 03RA4KZ

03RA4KZ is the ICD-10-PCS code for a replacement procedure on the left ulnar artery using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to resection of vessel with replacement, upper limb vessels, the ICD-9-CM procedure title it maps to (38.43).

For a different body part, codes include 03R04KZ (right internal mammary artery), 03R14KZ (left internal mammary artery), 03R24KZ (innominate artery), 03R34KZ (right subclavian artery), 03R44KZ (left subclavian artery), 03R54KZ (right axillary artery) and 23 more.

The same procedure with a different approach is coded 03RA0KZ (open).

With a different device, use 03RA47Z (autologous tissue substitute) and 03RA4JZ (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” and “Other O.R. Procedures for Injuries”.

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