ICD-10 Code J30.9 – Allergic rhinitis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J30.9 – Allergic rhinitis, unspecified
What it is
J30.9 identifies allergic rhinitis when the record confirms an allergic nasal condition but does not specify the trigger or type. Use it for rhinitis caused by allergy when documentation is nonspecific.
Clinical signs
Typical findings include sneezing, clear nasal discharge, nasal itching, and congestion. Clinical features vary; refer to documentation for the exact allergic presentation.
When to use this code
Use J30.9 when the clinician documents allergic rhinitis without naming pollen, animal dander, dust, or another specific allergen. It also fits when the note states allergic rhinitis but gives no further detail. If the record supports a more specific subtype, code that instead.
Do not use for
Do not use this code for nonallergic rhinitis, acute upper respiratory infection, or sinusitis. Check documentation if symptoms are present but allergy is not clearly stated.
Coding tip
Query for the allergen or subtype when the note says “allergic rhinitis” without detail, because a more specific code may be available.
