ICD-10 Code H65.91 – Unspecified nonsuppurative otitis media, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.91 – Unspecified nonsuppurative otitis media, right ear
What it is
This code identifies nonsuppurative otitis media affecting the right ear when the record does not specify the exact type. It means middle ear inflammation or fluid is present, without documented pus or perforation.
Clinical signs
Typical findings include ear pain, pressure, hearing reduction, or a sense of fullness. Clinical features vary; refer to documentation for evidence of middle ear effusion, erythema, or tympanic membrane changes.
When to use this code
Use H65.91 when the provider documents nonsuppurative otitis media in the right ear and does not name a more specific subtype. It is appropriate when the chart supports middle ear disease but lacks detail for a more exact code. Verify laterality before assigning it.
Do not use for
Do not use this code for suppurative otitis media, otitis externa, or cases involving a perforated eardrum. If the documentation names a different ear or a more specific diagnosis, code that instead.
Coding tip
Check the note for laterality and specificity; if the right ear is not clearly documented, query before coding.
