Malignant neoplasm of other specified sites of uterine adnexa

This code signifies the presence of a cancerous tumor originating in specific, but not otherwise classified, parts of the uterine adnexa. This includes malignant neoplasms affecting structures such as the broad ligament, round ligament, or uterosacral ligament, which are supporting structures of the uterus and ovaries.

Use this code when documentation clearly indicates a primary malignant neoplasm of a specified adnexal site other than the ovary, fallopian tube, or unspecified adnexa. This code is appropriate when the pathology report confirms malignancy and specifies a site like the broad ligament.

• Ensure the documentation specifies the exact adnexal site; avoid using for ovarian or fallopian tube malignancies.
• Confirm the neoplasm is primary to the adnexal site and not a metastatic lesion from another primary.
• Always sequence the malignancy code first when it is the reason for the encounter.
