Family history of tobacco abuse and dependence

This code indicates that a patient has a family history of substance use disorder involving tobacco. This includes a history of nicotine addiction or problematic tobacco use among immediate or extended family members. It signifies a genetic predisposition or environmental influence that may increase the patient's risk for similar issues.

Apply this code when documentation explicitly states a family history of tobacco abuse or dependence. This is often identified during patient intake, health risk assessments, or when evaluating a patient for substance use disorders. It is particularly relevant for patients presenting with respiratory, cardiovascular, or other tobacco-related health concerns.

• Ensure the documentation clearly specifies "family history" and "tobacco abuse/dependence."
• Do not use this code if the patient themselves has a history of tobacco use; use codes from category F17 instead.
• This code is for informational purposes and typically used as a secondary diagnosis to support medical necessity for counseling or screening.
