About 0WBN4ZX

0WBN4ZX is the ICD-10-PCS code for a excision procedure on the perineum, female using a percutaneous endoscopic 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 other local excision or destruction of vulva and perineum, the ICD-9-CM procedure title it maps to (71.3).

For a different body part, codes include 0WB04ZX (head), 0WB24ZX (face), 0WB34ZX (oral cavity and throat), 0WB44ZX (upper jaw), 0WB54ZX (lower jaw), 0WB64ZX (neck) and 7 more.

The same procedure with a different approach is coded 0WBN0ZX (open), 0WBN3ZX (percutaneous) and 0WBNXZX (external).

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.
