About 0UMMXZZ

0UMMXZZ is the ICD-10-PCS code for a reattachment procedure on the vulva using an external approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

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 0UMJXZZ (clitoris) and 0UMKXZZ (hymen).

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.
