About 05R147Z

05R147Z is the ICD-10-PCS code for a replacement procedure on the hemiazygos vein using a percutaneous endoscopic approach with autologous 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 05R047Z (azygos vein), 05R347Z (right innominate vein), 05R447Z (left innominate vein), 05R547Z (right subclavian vein), 05R647Z (left subclavian vein), 05R747Z (right axillary vein) and 19 more.

The same procedure with a different approach is coded 05R107Z (open).

With a different device, use 05R14JZ (synthetic substitute) and 05R14KZ (nonautologous tissue 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.
