ICD-10 Code H65.491 – Other chronic nonsuppurative otitis media, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.491 – Other chronic nonsuppurative otitis media, right ear
What it is
This code identifies chronic inflammation of the middle ear in the right ear without pus or active drainage. Use it when the record specifies a nonsuppurative otitis media process affecting the right side.
Clinical signs
Typical findings may include ear fullness, hearing reduction, or a persistent abnormal tympanic membrane. Clinical features vary; refer to documentation for laterality and whether the condition is chronic and nonsuppurative.
When to use this code
Use H65.491 when the provider documents chronic nonsuppurative otitis media limited to the right ear. It also fits follow-up visits for a known chronic condition when the diagnosis remains active and is being assessed.
Make sure the note distinguishes this from acute infection, suppurative disease, or bilateral involvement. If the record is unclear about the ear or the type of otitis media, check documentation before coding.
Do not use for
Do not use this code for acute otitis media, suppurative otitis media, or chronic disease involving the left ear or both ears. Check documentation if the chart only says “otitis media” without chronic nonsuppurative detail.
Coding tip
Verify both chronicity and right-ear laterality in the provider note before assigning H65.491.
