About 0WWN30Z

0WWN30Z is the ICD-10-PCS code for a revision procedure on the perineum, female using a percutaneous approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0WW030Z (head), 0WW130Z (cranial cavity), 0WW230Z (face), 0WW430Z (upper jaw), 0WW530Z (lower jaw), 0WW630Z (neck) and 12 more.

The same procedure with a different approach is coded 0WWN00Z (open), 0WWN40Z (percutaneous endoscopic) and 0WWNX0Z (external).

With a different device, use 0WWN31Z (radioactive element), 0WWN33Z (infusion device), 0WWN37Z (autologous tissue substitute), 0WWN3JZ (synthetic substitute), 0WWN3KZ (nonautologous tissue substitute) and 0WWN3YZ (other 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.
