ICD-10 Code L25.4 – Unspecified contact dermatitis due to food in contact with skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L25.4 – Unspecified contact dermatitis due to food in contact with skin
What it is
This code identifies contact dermatitis caused by food touching the skin, when the exact substance or reaction details are not documented. It is used for a skin inflammation linked to direct contact rather than ingestion.
Clinical signs
Typical findings include localized redness, itching, swelling, or rash at the contact site. Clinical features vary; refer to documentation.
When to use this code
Use L25.4 when the record states dermatitis or skin irritation from food contact, but does not name the specific food. It also fits when the clinician documents an unspecified contact reaction after handling, touching, or exposure to food on the skin.
Do not use for
Do not use this code for food allergy with systemic symptoms, ingestion-related reactions, or dermatitis from a known nonfood irritant. Check documentation if the record describes eczema, urticaria, or another more specific diagnosis.
Coding tip
Confirm that the note links the rash to food contact on the skin and that no more specific contact dermatitis code is documented.
