About 0UNC7ZZ

0UNC7ZZ is the ICD-10-PCS code for a release procedure on the cervix using a via natural or artificial opening 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 cervix and uterus, the ICD-9-CM procedure title it maps to (69.99).

For a different body part, codes include 0UN57ZZ (right fallopian tube), 0UN67ZZ (left fallopian tube), 0UN77ZZ (bilateral fallopian tubes), 0UN97ZZ (uterus), 0UNF7ZZ (cul-de-sac), 0UNG7ZZ (vagina) and 1 more.

The same procedure with a different approach is coded 0UNC0ZZ (open), 0UNC3ZZ (percutaneous), 0UNC4ZZ (percutaneous endoscopic) and 0UNC8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 749 (Other Female Reproductive System O.R. Procedures with CC/MCC) and DRG 750 (Other Female Reproductive System O.R. Procedures without CC/MCC), under the surgical category “Other Female Reproductive System O.R. Procedures”.

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