About 0UNG4ZZ

0UNG4ZZ is the ICD-10-PCS code for a release procedure on the vagina using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other repair of vagina, the ICD-9-CM procedure title it maps to (70.79).

For a different body part, codes include 0UN04ZZ (right ovary), 0UN14ZZ (left ovary), 0UN24ZZ (bilateral ovaries), 0UN44ZZ (uterine supporting structure), 0UN54ZZ (right fallopian tube), 0UN64ZZ (left fallopian tube) and 5 more.

The same procedure with a different approach is coded 0UNG0ZZ (open), 0UNG3ZZ (percutaneous), 0UNG7ZZ (via natural or artificial opening), 0UNG8ZZ (via natural or artificial opening endoscopic) and 0UNGXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC), DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Vagina, Cervix and Vulva Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
