Z803 - Family history of breast cancer

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that you have a family history of breast cancer, meaning one or more of your blood relatives (such as mother, sister, grandmother, or aunt) has been diagnosed with breast cancer. This information is important for your healthcare providers because having a family history of breast cancer may increase your own risk of developing the disease. Your doctor uses this code to document this family history in your medical records, which helps guide screening recommendations and preventive care decisions. This is not a diagnosis of cancer for you - it's simply documenting your family medical history.

Additional Information

This code is used for documentation purposes and risk assessment. It does not indicate you have cancer, but helps your healthcare team provide appropriate preventive care and screening based on your increased risk due to family history.
