About 0WHN0YZ

0WHN0YZ is the ICD-10-PCS code for a insertion procedure on the perineum, female using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0WH00YZ (head), 0WH10YZ (cranial cavity), 0WH20YZ (face), 0WH30YZ (oral cavity and throat), 0WH40YZ (upper jaw), 0WH50YZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHN3YZ (percutaneous) and 0WHN4YZ (percutaneous endoscopic).

With a different device, use 0WHN01Z (radioactive element) and 0WHN03Z (infusion 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.
