ICD-10 Code J31.0 – Chronic rhinitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J31.0 – Chronic rhinitis
What it is
J31.0 identifies chronic inflammation or irritation of the nasal lining that persists over time. Use it for ongoing rhinitis when documentation describes a chronic pattern rather than an acute infection.
Clinical signs
Typical findings include persistent nasal congestion, runny nose, sneezing, or postnasal drip. Clinical features vary; refer to documentation, and code only when the record supports a chronic diagnosis.
When to use this code
Use J31.0 when the provider documents chronic rhinitis, including longstanding noninfectious nasal inflammation. It is appropriate when symptoms are recurrent or persistent and the note does not specify a more exact subtype. If allergic, vasomotor, or infectious rhinitis is documented instead, code the stated condition.
Do not use for
Do not use J31.0 for acute rhinitis, sinusitis, or a clearly documented allergic cause. Check documentation if the record names another nasal disorder or provides a more specific diagnosis.
Coding tip
Look for the word “chronic” in the assessment, not just nasal symptoms, before assigning J31.0.
