About 0WWN4JZ

0WWN4JZ is the ICD-10-PCS code for a revision procedure on the perineum, female using a percutaneous endoscopic approach with synthetic substitute. 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 0WW04JZ (head), 0WW14JZ (cranial cavity), 0WW24JZ (face), 0WW44JZ (upper jaw), 0WW54JZ (lower jaw), 0WW64JZ (neck) and 10 more.

The same procedure with a different approach is coded 0WWN0JZ (open), 0WWN3JZ (percutaneous) and 0WWNXJZ (external).

With a different device, use 0WWN40Z (drainage device), 0WWN41Z (radioactive element), 0WWN43Z (infusion device), 0WWN47Z (autologous tissue substitute), 0WWN4KZ (nonautologous tissue substitute) and 0WWN4YZ (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.
