Food additives allergy status

This diagnosis code indicates a patient's documented history of an adverse immunological reaction to substances intentionally added to food for preservation, flavoring, or coloring. It signifies a true allergic response, not merely an intolerance or sensitivity, to food additives.

Assign this code when a patient's medical record clearly documents a diagnosed allergy to one or more food additives. This is appropriate for patients with a history of anaphylaxis, hives, angioedema, or other allergic symptoms triggered by specific food additives. It should be used to capture the patient's allergy status for risk assessment and treatment planning.

• Always confirm that the documentation specifies an allergy to food additives, not just an intolerance or adverse reaction.
• Do not use this code for general food allergies (e.g., peanut allergy); those have specific codes.
• This code is for the status of the allergy; if the patient is experiencing an acute allergic reaction, a code for the specific reaction (e.g., anaphylactic shock) should be primary, with this code as a secondary diagnosis if applicable.
