About 0WWN03Z

0WWN03Z is the ICD-10-PCS code for a revision procedure on the perineum, female using an open approach with infusion 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 0WW003Z (head), 0WW103Z (cranial cavity), 0WW203Z (face), 0WW403Z (upper jaw), 0WW503Z (lower jaw), 0WW603Z (neck) and 15 more.

The same procedure with a different approach is coded 0WWN33Z (percutaneous), 0WWN43Z (percutaneous endoscopic) and 0WWNX3Z (external).

With a different device, use 0WWN00Z (drainage device), 0WWN01Z (radioactive element), 0WWN07Z (autologous tissue substitute), 0WWN0JZ (synthetic substitute), 0WWN0KZ (nonautologous tissue substitute) and 0WWN0YZ (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.
