ICD-10 Code J30.1 – Allergic rhinitis due to pollen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J30.1 – Allergic rhinitis due to pollen
What it is
J30.1 identifies allergic rhinitis caused by pollen exposure, often called seasonal hay fever. Use it when the record shows a pollen-triggered nasal allergy rather than a nonspecific or perennial cause.
Clinical signs
Typical findings include sneezing, nasal congestion, runny nose, and itchy nose or eyes during pollen season. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents allergic rhinitis due to pollen, seasonal allergic rhinitis, or hay fever linked to pollen. It also fits visits for symptom evaluation when the diagnosis is clearly established in the chart. If the trigger is not specified, check documentation before assigning J30.1.
Do not use for
Do not use J30.1 for rhinitis due to nonpollen triggers, such as dust, animals, or foods. It is also not appropriate when the record only says rhinitis or nasal congestion without an allergic pollen cause.
Coding tip
Look for explicit provider documentation of pollen as the allergy trigger before coding J30.1.
