About 0UNF8ZZ
0UNF8ZZ is the ICD-10-PCS code for a release procedure on the cul-de-sac using a via natural or artificial opening 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 operations on cul-de-sac, the ICD-9-CM procedure title it maps to (70.92).
For a different body part, codes include 0UN08ZZ (right ovary), 0UN18ZZ (left ovary), 0UN28ZZ (bilateral ovaries), 0UN48ZZ (uterine supporting structure), 0UN58ZZ (right fallopian tube), 0UN68ZZ (left fallopian tube) and 5 more.
The same procedure with a different approach is coded 0UNF0ZZ (open), 0UNF3ZZ (percutaneous), 0UNF4ZZ (percutaneous endoscopic) and 0UNF7ZZ (via natural or artificial opening).
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.
