Dermatitis due to food taken internally

This code signifies an inflammatory skin reaction (dermatitis) that is directly caused by the ingestion of specific food substances. It represents an allergic or hypersensitivity response manifesting cutaneously due to internal exposure to an allergen.

Apply this code when documentation clearly indicates a diagnosis of dermatitis where the etiology is identified as a food item consumed by the patient. This is appropriate for conditions like food-induced eczema or urticaria where the causal link to ingested food is established.

• Requires physician documentation explicitly linking the dermatitis to food ingestion.
• Do not use for contact dermatitis from food; that would be coded differently.
• Consider an additional E-code (E988.2) to specify the type of food if known and documented.
