About 0UN98ZZ

0UN98ZZ is the ICD-10-PCS code for a release procedure on the uterus 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 division of endometrial synechiae, the ICD-9-CM procedure title it maps to (68.21).

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 0UN90ZZ (open), 0UN93ZZ (percutaneous), 0UN94ZZ (percutaneous endoscopic) and 0UN97ZZ (via natural or artificial opening).

It is an operating-room procedure in the MS-DRG logic for DRG 744 (D&C, Conization, Laparoscopy and Tubal Interruption with CC/MCC) and DRG 745 (D&C, Conization, Laparoscopy and Tubal Interruption without CC/MCC), under the surgical category “D&C, Conization, Laparoscopy and Tubal Interruption”.

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