Allergy to peanuts

This code signifies a documented adverse immunological reaction to peanuts. This reaction can range from mild symptoms like hives or gastrointestinal upset to severe, life-threatening anaphylaxis upon exposure to peanuts. It indicates a true allergy, not merely an intolerance.

This code is appropriate for patients with a confirmed diagnosis of peanut allergy, regardless of the severity or recency of their last reaction. It should be used when documenting a patient's medical history or when a peanut allergy is relevant to their current care, such as during an allergic reaction or when prescribing medications.

• Ensure the medical record clearly documents a diagnosis of peanut allergy, not just a sensitivity or intolerance.
• Do not use this code for a general food allergy unspecified; specify the allergen when known.
• Consider additional codes for the specific manifestations of the allergic reaction (e.g., anaphylaxis, urticaria) if present.
