About 05R40KZ

05R40KZ is the ICD-10-PCS code for a replacement procedure on the left innominate vein using an open 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 05R00KZ (azygos vein), 05R10KZ (hemiazygos vein), 05R30KZ (right innominate vein), 05R50KZ (right subclavian vein), 05R60KZ (left subclavian vein), 05R70KZ (right axillary vein) and 19 more.

The same procedure with a different approach is coded 05R44KZ (percutaneous endoscopic).

With a different device, use 05R407Z (autologous tissue substitute) and 05R40JZ (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.
