ICD-10 Code H65.413 – Chronic allergic otitis media, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.413 – Chronic allergic otitis media, bilateral
What it is
This code identifies chronic allergic otitis media affecting both ears. It describes a long-lasting middle ear condition associated with allergic inflammation or allergy-related fluid changes.
Clinical signs
Typical findings include persistent middle ear effusion, ear fullness, muffled hearing, or recurrent symptoms involving both ears. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic allergic otitis media in both ears, or clearly links bilateral middle ear disease to an allergic process. It is appropriate when the diagnosis is confirmed in the record, even if symptoms are not fully detailed. Check documentation if laterality or chronicity is unclear.
Do not use for
Do not use it for acute otitis media, nonspecific ear pain, or unilateral disease. Avoid this code if the record does not support a chronic allergic cause.
Coding tip
Confirm both laterality and the word “chronic” in the provider note before assigning H65.413.
