About 02WG08Z

02WG08Z is the ICD-10-PCS code for a revision procedure on the mitral valve using an open approach with zooplastic tissue. 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 02WA08Z (heart), 02WF08Z (aortic valve), 02WH08Z (pulmonary valve), 02WJ08Z (tricuspid valve) and 02WY08Z (great vessel).

The same procedure with a different approach is coded 02WG38Z (percutaneous) and 02WG48Z (percutaneous endoscopic).

With a different device, use 02WG07Z (autologous tissue substitute), 02WG0JZ (synthetic substitute) and 02WG0KZ (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.
