About the 0UN Code Range
The ICD-10-PCS root operation Release (Code 0UN) in the Medical and Surgical section refers to freeing a body part from abnormal physical restrictions by cutting or otherwise removing the causative tissue. Within the Female Reproductive System, this operation is used to relieve adhesions or restrictions impairing normal function.
Examples of this procedure include releasing the Right Ovary using various approaches such as Open (0UN00ZZ), Percutaneous (0UN03ZZ), or Endoscopic via natural or artificial openings (0UN08ZZ). Similar codes exist for releasing the Left Ovary, Bilateral Ovaries, and other key structures like the Uterus (0UN90ZZ), Cervix (0UNC0ZZ), Fallopian Tubes, and the Vagina. The approach chosen—ranging from external to percutaneous endoscopic—affects code selection. Accurate use of these release codes supports precise procedural documentation of surgeries aimed at restoring mobility and function within the female reproductive organs by removing adhesions or restrictive tissue.
