About 0UBMXZX

0UBMXZX is the ICD-10-PCS code for a excision procedure on the vulva using an external approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of vulva, the ICD-9-CM procedure title it maps to (71.11).

For a different body part, codes include 0UBGXZX (vagina), 0UBJXZX (clitoris), 0UBKXZX (hymen) and 0UBLXZX (vestibular gland).

The same procedure with a different approach is coded 0UBM0ZX (open).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Vagina, Cervix and Vulva Procedures”.

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