What This Code Means

Cancer that has spread to the genital organs (such as the uterus, prostate, or other reproductive structures) from a cancer that started elsewhere.

Coding Tips

•This is a general code for secondary cancer to genital organs; use more specific codes (C79.60-C79.63 for ovaries) when available.
•Ensure the primary cancer site is coded separately and sequenced first.

Clinical Significance

Secondary malignant neoplasm of genital organs captures metastatic cancer spreading to reproductive structures such as the uterus, cervix, vagina, vulva, prostate, or testes from a primary cancer elsewhere. This is distinct from primary genital organ cancers and indicates advanced-stage disease. Ovarian metastases have their own specific codes (C79.60-C79.63) and should not be coded here.

Documentation Requirements

✓Primary cancer site documented and coded separately
✓Specific genital organ involved — uterus, cervix, vagina, vulva, prostate, testis, etc.
✓Pathological confirmation distinguishing metastatic from primary genital organ cancer
✓Imaging confirmation of genital organ involvement
✓Treatment plan — surgical, radiation, systemic therapy

Commonly Confused Codes

C79.60-C79.63 — Secondary malignant neoplasm of ovary (with laterality); ovarian metastases should use these specific codes, NOT C79.82 C53.0-C55 — Primary malignant neoplasm of cervix, uterus; distinguish primary from metastatic genital organ cancer C61 — Primary malignant neoplasm of prostate; prostate cancer is overwhelmingly primary, not metastatic TO the prostate C79.89 — Secondary malignant neoplasm of other specified sites; genital organs have their own specific code
