Z80.4Family history of malignant neoplasm of genital organs

Z80.4 is the ICD-10-CM diagnosis code for family history of malignant neoplasm of genital organs. It belongs to category Z80 (family history of primary malignant neoplasm), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services).
