Malignant neoplasm of female genital organ, site unspecified

This code signifies a confirmed malignant tumor originating in a female reproductive organ, where the specific anatomical site within the female genital system has not been identified or documented. It indicates a primary malignancy rather than a secondary or metastatic lesion.

Use this code when documentation confirms a primary malignant neoplasm of a female genital organ, but the medical record lacks specificity regarding the exact organ involved (e.g., ovary, uterus, cervix, vagina, vulva). This code is appropriate when the pathologist or clinician has confirmed malignancy but cannot pinpoint the precise origin within the female genital tract.

• Avoid using this code if a more specific site (e.g., ovary, uterus) is documented; always code to the highest level of specificity available.
• Query the provider for clarification on the specific site if possible, as this code indicates incomplete documentation.
• This code is generally reserved for situations where the primary site remains unknown after diagnostic workup.
