ICD-10 Code L27.2 – Dermatitis due to ingested food (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L27.2 – Dermatitis due to ingested food
What it is
L27.2 identifies dermatitis caused by food taken by mouth. Use it when documentation links a skin eruption or allergic-type dermatitis directly to an ingested food trigger.
Clinical signs
Typical findings include an acute rash, itching, redness, or hives after eating a specific food. Clinical features vary; refer to documentation.
When to use this code
Use L27.2 when the record states dermatitis is due to ingested food, such as a documented food-related skin reaction. You should also use it when the clinician identifies the food trigger and the skin condition is the main reason for care.
Check documentation if the reaction is described only as a general allergy, intolerance, or nonspecific rash without a clear food cause.
Do not use for
Do not use this code for contact dermatitis, food poisoning, or gastrointestinal food allergy symptoms without skin involvement. Check documentation if the cause is uncertain.
Coding tip
Assign L27.2 only when the chart clearly ties the dermatitis to ingested food, not merely a suspected dietary trigger.
