About 0UNKXZZ

0UNKXZZ is the ICD-10-PCS code for a release procedure on the hymen 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 Hymenorrhaphy, the ICD-9-CM procedure title it maps to (70.76).

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

The same procedure with a different approach is coded 0UNK0ZZ (open), 0UNK3ZZ (percutaneous), 0UNK4ZZ (percutaneous endoscopic), 0UNK7ZZ (via natural or artificial opening) and 0UNK8ZZ (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) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical category “Vagina, Cervix and Vulva Procedures”.

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