Other allergic and dietetic gastroenteritis and colitis

📋Clinical Description

This code signifies inflammation of the gastrointestinal tract (stomach, small intestine, and/or colon) due to an allergic reaction or dietary intolerance, excluding eosinophilic or food protein-induced enterocolitis syndromes. It represents a non-specific allergic or diet-related GI inflammatory response.

🎯When to Use

Apply this code when documentation specifies gastroenteritis or colitis attributed to an allergy or dietary factor, but without further specificity to eosinophilic or food protein-induced conditions. This is appropriate for reactions to food, medications, or other ingested substances causing GI symptoms like diarrhea, vomiting, or abdominal pain.

💡Coding Tips

Ensure documentation clearly links the gastroenteritis/colitis to an allergic or dietetic cause.
Differentiate from K52.1 (Toxic gastroenteritis and colitis) and K52.21 (Food protein-induced enterocolitis syndrome) based on etiology.
Code any specific allergens or dietary substances identified, if applicable, using Z91.0- codes for allergies or intolerances.
