Superficial endometriosis of ovary, unspecified ovary

This code signifies the presence of endometrial tissue on the surface of an ovary, without specifying which ovary is affected. This condition involves the growth of tissue similar to the uterine lining outside the uterus, specifically on the ovarian surface.

Apply this code when documentation confirms superficial endometriosis of an ovary, and the laterality (left or right) is not specified. This is typically used when surgical findings or imaging reports indicate ovarian involvement but lack precise laterality.

• Ensure documentation explicitly states "superficial" involvement of the ovary.
• Avoid using this code if laterality (left or right ovary) is documented; instead, use the more specific N80.111 or N80.112.
• Consider sequencing this code after codes for associated symptoms or other endometriosis sites if applicable.
