0W9N0ZZDrainage of Female Perineum, Open Approach

0W9N0ZZ is the ICD-10-PCS code for a drainage procedure on the perineum, female using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of vulva and perineum, the ICD-9-CM procedure title it maps to (71.09).

For a different body part, codes include 0W900ZZ (head), 0W910ZZ (cranial cavity), 0W920ZZ (face), 0W930ZZ (oral cavity and throat), 0W940ZZ (upper jaw), 0W950ZZ (lower jaw) and 13 more.

The same procedure with a different approach is coded 0W9N3ZZ (percutaneous) and 0W9N4ZZ (percutaneous endoscopic).

With a different device, use 0W9N00Z (drainage device).

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.
