About 0UBM0ZZ

0UBM0ZZ is the ICD-10-PCS code for a excision procedure on the vulva using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to unilateral vulvectomy, the ICD-9-CM procedure title it maps to (71.61).

For a different body part, codes include 0UB00ZZ (right ovary), 0UB10ZZ (left ovary), 0UB20ZZ (bilateral ovaries), 0UB40ZZ (uterine supporting structure), 0UB50ZZ (right fallopian tube), 0UB60ZZ (left fallopian tube) and 8 more.

The same procedure with a different approach is coded 0UBMXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical category “Vagina, Cervix and Vulva Procedures”.

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