Family history of allergic disorders

This code signifies a documented family history of allergic conditions, indicating a genetic predisposition to developing allergies. It does not represent an active allergic reaction or a personal history of allergies for the patient themselves, but rather a familial pattern of such disorders.

Apply this code when a patient's medical record explicitly states that one or more immediate family members (e.g., parents, siblings) have a history of allergic diseases like asthma, hay fever, or food allergies. This information is often gathered during initial patient intake or when evaluating a patient for potential allergic conditions.

• Ensure the documentation clearly specifies "family history" and not the patient's personal history.
• Use this code as a secondary diagnosis to provide supporting information for the patient's current condition or risk factors.
• Do not use this code if the family history is for a non-allergic condition, even if it's an immune disorder.
