ICD-10 Code J30.5 – Allergic rhinitis due to food (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J30.5 – Allergic rhinitis due to food
What it is
J30.5 identifies allergic rhinitis triggered by food exposure. Use it when the nasal allergy symptoms are documented as caused by a specific food allergen.
Clinical signs
Typical findings include sneezing, nasal congestion, rhinorrhea, and itching after eating or exposure to a food allergen. Clinical features vary; refer to documentation.
When to use this code
Use J30.5 when the provider clearly links rhinitis to food allergy rather than to pollen, dust, or another trigger. Apply it when the record states food-induced nasal allergy or allergic rhinitis due to food.
If the note only mentions a general food allergy without rhinitis, this code is not supported. Check documentation for the specific allergic manifestation and trigger.
Do not use for
Do not use this code for nonallergic rhinitis, isolated urticaria, or unspecified food allergy without rhinitis. If the trigger is unclear, check documentation.
Coding tip
Confirm both the allergic rhinitis diagnosis and the food trigger in the provider note before assigning J30.5.
