Malignant neoplasm of other specified sites of female genital organs

This code signifies a primary cancerous tumor originating in a specific, but less common, location within the female reproductive system that is not otherwise classified. This includes malignancies of the broad ligament, round ligament, parametrium, or other specified supporting structures of the uterus and ovaries. It represents a confirmed diagnosis of invasive carcinoma.

Use this code when documentation clearly indicates a primary malignant neoplasm of a specified female genital organ site other than the more common locations (e.g., ovary, uterus, cervix, vagina, vulva, fallopian tube). Pathological confirmation of malignancy is essential. Examples include carcinoma of the broad ligament or parametrium.

• Ensure the documentation specifies the exact "other" site; if not specified, consider a more general "unspecified" code if available and appropriate.
• Distinguish from secondary (metastatic) malignancies to these sites, which would be coded differently.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless a complication or symptom is the primary focus.
