Malignant neoplasm of unspecified broad ligament

This code signifies a cancerous tumor originating in the broad ligament, a fold of peritoneum that extends from the sides of the uterus to the walls of the pelvis, when the specific side (right or left) is not documented. It indicates a primary malignancy of this supporting structure of the female reproductive system.

Apply this code when documentation confirms a malignant neoplasm of the broad ligament but does not specify laterality. This is appropriate for pathology reports or operative notes that identify the broad ligament as the tumor site without further anatomical precision.

• Always seek clarification from the provider if laterality (right or left broad ligament) is not documented, as more specific codes exist.
• Do not use this code if the malignancy is secondary or metastatic to the broad ligament; instead, code the primary site and a secondary malignancy code.
• Ensure the documentation clearly states "malignant neoplasm" to differentiate from benign or uncertain broad ligament masses.
