Dermatitis due to ingested food

This code signifies an inflammatory skin reaction, such as eczema or rash, that is directly caused by the consumption of specific food items. The body's immune system reacts adversely to ingested food allergens or irritants, manifesting as dermatological symptoms.

Apply this code when documentation clearly links a patient's dermatitis to a dietary intake, such as an allergic reaction to peanuts or a sensitivity to gluten causing skin manifestations. Supporting documentation should include physician notes detailing the food trigger and the resulting skin condition.

• Differentiate from contact dermatitis; this code is specifically for ingested substances.
• Ensure the medical record explicitly states the causal link between food ingestion and the skin reaction.
• Consider additional codes for specific food allergies (e.g., T78.0- for anaphylactic reaction to food) if applicable.
