Family history of malignant neoplasm of ovary

This diagnosis code indicates that a patient has a family history of ovarian cancer. It signifies that one or more immediate or extended family members have been diagnosed with a malignant neoplasm originating in the ovary. This history is a significant risk factor for the patient's own potential development of ovarian cancer.

Use this code when documenting a patient's personal medical history, specifically when a family member (e.g., mother, sister, grandmother, aunt) has been diagnosed with ovarian cancer. This is particularly relevant during preventative screenings, genetic counseling, or when assessing a patient's risk profile for gynecological malignancies. It supports medical necessity for increased surveillance or further investigation.

• Always specify the type of cancer in the family history when known (e.g., ovarian, breast) for maximum specificity.
• Do not use this code if the patient themselves has a personal history of ovarian cancer; use the appropriate personal history code (e.g., Z85.43).
• This code is often used as a secondary diagnosis to support medical necessity for services like genetic testing or increased screening.
