About 0UN28ZZ

0UN28ZZ is the ICD-10-PCS code for a release procedure on the bilateral ovaries 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 lysis of adhesions of ovary and fallopian tube, the ICD-9-CM procedure title it maps to (65.89).

For a different body part, codes include 0UN08ZZ (right ovary), 0UN18ZZ (left ovary), 0UN48ZZ (uterine supporting structure), 0UN58ZZ (right fallopian tube), 0UN68ZZ (left fallopian tube), 0UN78ZZ (bilateral fallopian tubes) and 5 more.

The same procedure with a different approach is coded 0UN20ZZ (open), 0UN23ZZ (percutaneous) and 0UN24ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 731 (Uterine and Adnexa Procedures for Malignancy with MCC), DRG 732 (Uterine and Adnexa Procedures for Malignancy with CC), DRG 733 (Uterine and Adnexa Procedures for Malignancy without CC/MCC), DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Uterine and Adnexa Procedures for Malignancy”, “Uterine and Adnexa Procedures for Non-Malignancy”, “Other O.R. Procedures for Injuries” and 1 more.

It was added in FY2018, effective October 1, 2017.
