About 02RG37Z

02RG37Z is the ICD-10-PCS code for a replacement procedure on the mitral valve using a percutaneous 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 open and other replacement of mitral valve with tissue graft, the ICD-9-CM procedure title it maps to (35.23).

For a different body part, codes include 02RF37Z (aortic valve), 02RH37Z (pulmonary valve) and 02RJ37Z (tricuspid valve).

The same procedure with a different approach is coded 02RG07Z (open) and 02RG47Z (percutaneous endoscopic).

With a different device, use 02RG38Z (zooplastic tissue), 02RG3JZ (synthetic substitute) and 02RG3KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 266 (Endovascular Cardiac Valve Replacement and Supplement Procedures with MCC) and DRG 267 (Endovascular Cardiac Valve Replacement and Supplement Procedures without MCC), under the surgical category “Endovascular Cardiac Valve Replacement and Supplement Procedures”.

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