About 03R34KZ

03R34KZ is the ICD-10-PCS code for a replacement procedure on the right subclavian 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, thoracic vessels, the ICD-9-CM procedure title it maps to (38.45).

For a different body part, codes include 03R04KZ (right internal mammary artery), 03R14KZ (left internal mammary artery), 03R24KZ (innominate artery), 03R44KZ (left subclavian artery), 03R54KZ (right axillary artery), 03R64KZ (left axillary artery) and 23 more.

The same procedure with a different approach is coded 03R30KZ (open).

With a different device, use 03R347Z (autologous tissue substitute) and 03R34JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 212 (Concomitant Aortic and Mitral Valve Procedures), DRG 216 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with MCC) and DRG 217 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with CC), under the surgical categories “Major Chest Procedures”, “Concomitant Aortic and Mitral Valve Procedures”, “” and 3 more.

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