Allergy to other foods

This code indicates a documented adverse immunological reaction to a food substance that is not specifically categorized elsewhere. It signifies a true food allergy, distinct from food intolerance, where the body's immune system overreacts to a particular food. Symptoms can range from mild (e.g., hives, itching) to severe (e.g., anaphylaxis).

Assign this code when a patient has a confirmed allergy to a food not covered by more specific ICD-10-CM codes (e.g., peanut, milk, egg, soy). This includes allergies to less common foods or combinations of foods not individually specified. It is appropriate for both acute allergic reactions and for documenting a known allergy for future care planning.

• Always sequence this code after the code for the acute allergic reaction, if applicable.
• Ensure documentation clearly specifies the food allergen if possible, even if it falls under "other foods."
• Do not use for food intolerances (e.g., lactose intolerance) or adverse reactions that are not immunologically mediated.
