ICD-10 Code H65.9 – Unspecified nonsuppurative otitis media (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.9 – Unspecified nonsuppurative otitis media
What it is
H65.9 identifies nonsuppurative otitis media when the middle-ear inflammation or fluid is documented, but the record does not specify a more exact type. Use it for non-purulent middle-ear disease when details are limited.
Clinical signs
Typical findings may include ear fullness, decreased hearing, or visible middle-ear effusion on exam. Clinical features vary; refer to documentation.
When to use this code
Use H65.9 when the provider documents nonsuppurative otitis media without naming serous, mucoid, or another specific subtype. It also fits when the note confirms middle-ear inflammation or effusion, but the exact form is not recorded. Check documentation if the condition is acute, suppurative, or otherwise better specified.
Do not use for
Do not use this code for suppurative otitis media or for acute infections with pus or perforation. It is also not the best choice when the record clearly states a more specific nonsuppurative subtype.
Coding tip
Before assigning H65.9, scan the note for a more specific middle-ear diagnosis, because the unspecified code should be your fallback.
