About 02WG37Z

02WG37Z is the ICD-10-PCS code for a revision procedure on the mitral valve using a percutaneous approach with autologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to revision of corrective procedure on heart, the ICD-9-CM procedure title it maps to (35.95).

For a different body part, codes include 02WA37Z (heart), 02WF37Z (aortic valve), 02WH37Z (pulmonary valve), 02WJ37Z (tricuspid valve) and 02WY37Z (great vessel).

The same procedure with a different approach is coded 02WG07Z (open) and 02WG47Z (percutaneous endoscopic).

With a different device, use 02WG38Z (zooplastic tissue), 02WG3JZ (synthetic substitute) and 02WG3KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 319 (Other Endovascular Cardiac Valve Procedures with MCC) and DRG 320 (Other Endovascular Cardiac Valve Procedures without MCC), under the surgical category “Other Endovascular Cardiac Valve Procedures”.

It was added in FY2018, effective October 1, 2017.
