Food protein-induced enteropathy

This code represents an inflammatory condition of the small intestine triggered by an adverse immune reaction to specific food proteins. It typically manifests with gastrointestinal symptoms such as vomiting, diarrhea, and poor weight gain, often seen in infants and young children. This condition is distinct from immediate IgE-mediated food allergies.

Use this code when documentation clearly indicates a diagnosis of enteropathy specifically induced by food proteins, such as food protein-induced enterocolitis syndrome (FPIES) or food protein-induced proctocolitis. Supporting documentation should detail the identified food trigger(s) and the characteristic gastrointestinal symptoms.

• Differentiate from other forms of enteritis or colitis not specifically linked to food protein induction.
• Do not use for general food allergies (e.g., IgE-mediated reactions) or lactose intolerance.
• Consider sequencing with codes for specific food allergies (e.g., Z91.01- for peanut allergy) if the food trigger is identified and relevant to the encounter.
