About 02RW08Z

02RW08Z is the ICD-10-PCS code for a replacement procedure on the thoracic aorta, descending using an open approach with zooplastic tissue. 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 02R508Z (atrial septum), 02R608Z (right atrium), 02R708Z (left atrium), 02R908Z (chordae tendineae), 02RD08Z (papillary muscle), 02RF08Z (aortic valve) and 14 more.

The same procedure with a different approach is coded 02RW48Z (percutaneous endoscopic).

With a different device, use 02RW07Z (autologous tissue substitute), 02RW0JZ (synthetic substitute) and 02RW0KZ (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.
