About 0WUN0KZ

0WUN0KZ is the ICD-10-PCS code for a supplement procedure on the perineum, female using an open approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to other repair of vulva and perineum, the ICD-9-CM procedure title it maps to (71.79).

For a different body part, codes include 0WU00KZ (head), 0WU20KZ (face), 0WU40KZ (upper jaw), 0WU50KZ (lower jaw), 0WU60KZ (neck), 0WU80KZ (chest wall) and 5 more.

The same procedure with a different approach is coded 0WUN4KZ (percutaneous endoscopic).

With a different device, use 0WUN07Z (autologous tissue substitute) and 0WUN0JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC), DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Vagina, Cervix and Vulva Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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