2025 ICD-10-CM code J30.5
Allergic rhinitis due to food.
Medical necessity for J30.5 is established when the documentation clearly supports the diagnosis of allergic rhinitis specifically triggered by food. Symptoms must impact the patient's quality of life, requiring medical intervention.
Clinicians diagnose allergic rhinitis based on a detailed medical history, physical examination, and sometimes allergy testing. The history focuses on symptom patterns, including when they occur (perennial or seasonal), duration, and triggers. Physical exam assesses nasal passages for swelling, color, and discharge. Allergy tests, like skin prick or blood tests, can pinpoint specific food allergens.

Skin prick testing reveals shellfish allergy., A 40-year-old individual develops hives, facial swelling, and difficulty breathing shortly after eating eggs. Blood tests confirm egg allergy. The individual also experiences allergic rhinitis symptoms along with the anaphylactic reaction.
