About 02RX4JZ

02RX4JZ is the ICD-10-PCS code for a replacement procedure on the thoracic aorta, ascending/arch using a percutaneous endoscopic approach with synthetic 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 02R54JZ (atrial septum), 02R64JZ (right atrium), 02R74JZ (left atrium), 02R94JZ (chordae tendineae), 02RD4JZ (papillary muscle), 02RF4JZ (aortic valve) and 14 more.

The same procedure with a different approach is coded 02RX0JZ (open).

With a different device, use 02RX47Z (autologous tissue substitute), 02RX48Z (zooplastic tissue) and 02RX4KZ (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 209 (Complex Aortic Arch Procedures), DRG 212 (Concomitant Aortic and Mitral Valve Procedures) and DRG 216 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with MCC), under the surgical categories “Major Chest Procedures”, “Complex Aortic Arch Procedures”, “Concomitant Aortic and Mitral Valve Procedures” and 4 more.

It was added in FY2017, effective October 1, 2016.
