About 02RK4KZ

02RK4KZ is the ICD-10-PCS code for a replacement procedure on the right ventricle using a percutaneous endoscopic 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 repair of endocardial cushion defect with tissue graft, the ICD-9-CM procedure title it maps to (35.63).

For a different body part, codes include 02R54KZ (atrial septum), 02R64KZ (right atrium), 02R74KZ (left atrium), 02R94KZ (chordae tendineae), 02RD4KZ (papillary muscle), 02RF4KZ (aortic valve) and 14 more.

The same procedure with a different approach is coded 02RK0KZ (open).

With a different device, use 02RK47Z (autologous tissue substitute), 02RK48Z (zooplastic tissue) and 02RK4JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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