Other adverse food reactions, not elsewhere classified

This code signifies an adverse reaction to food that is not an IgE-mediated allergy or a food intolerance with a more specific classification. It encompasses a range of non-allergic, non-intolerance responses to food components, often involving gastrointestinal, dermatological, or systemic symptoms.

Use this code when documentation indicates an adverse reaction to food that does not meet criteria for a true food allergy (e.g., anaphylaxis, urticaria with IgE involvement) or a specific food intolerance (e.g., lactose intolerance, celiac disease). This is appropriate for reactions where the mechanism is unclear or not otherwise specified.

• Ensure documentation clearly states the reaction is not an allergy or a specific intolerance.
• Avoid using this code if a more specific food allergy (e.g., 995.6x) or food intolerance (e.g., 271.3) code is applicable.
• Always sequence this code after the primary diagnosis if the adverse reaction is a secondary condition.
