ICD-10 Code J30.2 – Other seasonal allergic rhinitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J30.2 – Other seasonal allergic rhinitis
What it is
J30.2 identifies seasonal allergic rhinitis caused by environmental allergens that appear during specific times of year. Use it for hay fever or similar seasonal nasal allergy patterns when documentation does not specify a more exact allergic rhinitis code.
Clinical signs
Typical findings include sneezing, runny nose, nasal congestion, and itchy eyes or nose during a particular season. Clinical features vary; refer to documentation.
When to use this code
Use J30.2 when the provider documents seasonal allergic rhinitis, seasonal hay fever, or a similar seasonal allergy diagnosis. It fits cases where symptoms recur predictably with pollen or other seasonal triggers. If the chart does not clearly support seasonality, check documentation.
Do not use for
Do not use this code for perennial allergic rhinitis, acute upper respiratory infections, or nonspecific nasal congestion without an allergic diagnosis. Check documentation if the record suggests a different rhinitis type.
Coding tip
Look for a documented seasonal trigger or timing pattern before assigning J30.2.
