Family history of malignant neoplasm of breast

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

Use this code when documenting a patient's personal medical history that includes a familial predisposition to breast malignancy. This is often identified during routine screenings, preventative care visits, or when a patient presents with concerns related to breast health. It is crucial for risk assessment and guiding screening recommendations.

• Always document the specific family member(s) affected and their relationship to the patient in the medical record.
• Do not use this code if the patient themselves has a personal history of breast cancer; use a personal history code instead.
• This code is typically used as a secondary diagnosis to support medical necessity for increased surveillance or genetic counseling.
