Family history of malignant neoplasm of trachea, bronchus, and lung

This code indicates a patient's family history of a malignant tumor originating in the trachea, bronchi, or lungs. It signifies a genetic predisposition or increased risk for these specific types of cancer due to a family member's diagnosis. This is distinct from a personal history of cancer.

Use this code when documenting a patient's increased risk for lung, tracheal, or bronchial cancer based on a confirmed diagnosis in a first-degree relative (e.g., parent, sibling, child) or other close family member. This is often identified during a comprehensive medical history intake or risk assessment.

• Only use this code for a family history, not a personal history of cancer.
• Ensure the family member's cancer was specifically of the trachea, bronchus, or lung.
• This code is typically used as a secondary diagnosis to support medical necessity for screening or counseling.
