About 02R507Z

02R507Z is the ICD-10-PCS code for a replacement procedure on the atrial septum using an open 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 other repair of heart and pericardium, the ICD-9-CM procedure title it maps to (37.49).

For a different body part, codes include 02R607Z (right atrium), 02R707Z (left atrium), 02R907Z (chordae tendineae), 02RD07Z (papillary muscle), 02RF07Z (aortic valve), 02RG07Z (mitral valve) and 14 more.

The same procedure with a different approach is coded 02R547Z (percutaneous endoscopic).

With a different device, use 02R508Z (zooplastic tissue), 02R50JZ (synthetic substitute) and 02R50KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.

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