About 0UNGXZZ

0UNGXZZ is the ICD-10-PCS code for a release procedure on the vagina using an external 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 lysis of intraluminal adhesions of vagina, the ICD-9-CM procedure title it maps to (70.13).

For a different body part, codes include 0UNJXZZ (clitoris), 0UNKXZZ (hymen), 0UNLXZZ (vestibular gland) and 0UNMXZZ (vulva).

The same procedure with a different approach is coded 0UNG0ZZ (open), 0UNG3ZZ (percutaneous), 0UNG4ZZ (percutaneous endoscopic), 0UNG7ZZ (via natural or artificial opening) and 0UNG8ZZ (via natural or artificial opening endoscopic).

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.
