ICD-10 Code C57.7 – Malignant neoplasm of other specified female genital organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C57.7 – Malignant neoplasm of other specified female genital organs
What it is
This code identifies a malignant tumor arising in a female genital organ not named in the more specific C57 categories. Use it when the record clearly states a cancer in an “other specified” site.
Clinical signs
Clinical features vary by tumor location and may include a documented pelvic mass, abnormal bleeding, pain, or incidental imaging findings. Confirm the anatomic site and malignant nature in the medical record.
When to use this code
Use C57.7 when the provider documents a primary malignant neoplasm in a female genital organ that is not separately classified elsewhere in the C57 series. It is appropriate when the site is specified enough to support “other specified” rather than an unspecified genital malignancy. Check documentation if the note names a more exact organ or uses a metastatic site.
Do not use for
Do not use this code for malignant neoplasms of cervix, uterus, ovary, vulva, vagina, or other more specific female genital sites. Do not use it when the primary site is unknown or when the tumor is metastatic to the female genital organ.
Coding tip
Verify the exact anatomic site and whether the tumor is primary or secondary before assigning C57.7.
