Family history of stroke

This code indicates a patient has a family history of cerebrovascular accident (CVA), commonly known as a stroke. This means one or more immediate blood relatives (e.g., parent, sibling, child) or other close family members have experienced a stroke. It signifies an increased genetic predisposition or shared environmental risk factor for the patient.

Assign this code when documentation explicitly states a family history of stroke, even if the patient has not personally experienced a stroke. It is often used as a secondary diagnosis to support medical necessity for preventative screenings, risk factor management, or when evaluating symptoms that could be related to stroke risk.

• Always ensure the documentation clearly specifies "family history" of stroke, not just a personal history.
• This code is for a history of stroke in the family, not for a patient's current or past stroke.
• Use this code in conjunction with other codes that describe the patient's current health status or reasons for encounter.
