2025 ICD-10-CM code C57.9
Malignant neoplasm of female genital organ, unspecified.
Medical necessity for the use of C57.9 must be supported by documentation indicating the presence of a malignant neoplasm in the female genital area without identification of the specific site.
Providers diagnose the disease based on history, symptoms, and gynecological examination, including a pap smear. Cystoscopy, proctoscopy, and ultrasound help assess whether the cancer has spread to the rectum, bladder, or other pelvic organs.A biopsy, imaging tests (X-rays, CT scans, MRI, and PET) are also used. Treatment may involve chemotherapy, radiation therapy, and surgery.
In simple words: Cancer of the female reproductive organs, where the exact location isn't specified.
Malignant neoplasm of the female genital organs (reproductive or sex organs) refers to the abnormal growth of cells that multiply and can spread to nearby tissues.This code is used when the provider does not document the specific female genital organ involved.
Example 1: A patient presents with irregular vaginal bleeding and pelvic pain. After a thorough examination, including a biopsy, a malignant neoplasm is confirmed, but the specific organ of origin is undetermined. C57.9 is used., A patient undergoes a hysterectomy for a suspected malignancy. Pathology report shows malignancy in the female genital tract but does not identify origin. C57.9 is used., A patient with a history of abnormal pap smears, pain, and heavy bleeding has imaging done. Imaging suggests malignancy but does not pinpoint the origin. A biopsy is inconclusive regarding the specific site. C57.9 is used.
Medical history, symptoms (pelvic pain, abnormal bleeding, discharge), physical exam findings, Pap smear results, biopsy reports, imaging reports (ultrasound, CT, MRI, PET), and operative reports (if applicable).
