About 02R907Z

02R907Z is the ICD-10-PCS code for a replacement procedure on the chordae tendineae 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 operations on chordae tendineae, the ICD-9-CM procedure title it maps to (35.32).

For a different body part, codes include 02R507Z (atrial septum), 02R607Z (right atrium), 02R707Z (left atrium), 02RD07Z (papillary muscle), 02RF07Z (aortic valve), 02RG07Z (mitral valve) and 14 more.

The same procedure with a different approach is coded 02R947Z (percutaneous endoscopic).

With a different device, use 02R908Z (zooplastic tissue), 02R90JZ (synthetic substitute) and 02R90KZ (nonautologous tissue 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.
