Malignant neoplasm of broad ligament of uterus

This code signifies the presence of a cancerous tumor originating in the broad ligament of the uterus. The broad ligament is a fold of peritoneum that extends from the sides of the uterus to the walls and floor of the pelvis, and a malignant neoplasm in this location is a rare gynecological cancer.

Apply this code when documentation clearly states a primary malignant neoplasm of the broad ligament. This diagnosis is typically confirmed through biopsy and histopathological examination. It should be used for the initial diagnosis and subsequent encounters related to the treatment of this specific cancer.

• Ensure the documentation specifies "malignant" and "broad ligament" to differentiate from benign or other uterine/adnexal cancers.
• Do not confuse with malignant neoplasms of the uterus itself (e.g., endometrial, cervical) or other adnexal structures like the ovaries or fallopian tubes.
• Sequence as the primary diagnosis when the broad ligament malignancy is the reason for the encounter, followed by codes for any metastases or complications.
