ICD-10 Code H65.04 – Acute serous otitis media, recurrent, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.04 – Acute serous otitis media, recurrent, right ear
What it is
This code identifies recurrent acute serous otitis media affecting the right ear. It describes fluid behind the eardrum without signs of acute bacterial infection, with repeated episodes documented in the right ear.
Clinical signs
Common findings include ear fullness, muffled hearing, and a visible middle-ear effusion on examination. Clinical features vary; refer to documentation for recurrence and right-sided involvement.
When to use this code
Use H65.04 when the record clearly states recurrent acute serous otitis media in the right ear. You should also use it when the provider documents persistent or repeated serous middle-ear effusion on the right with no alternative diagnosis.
Do not use for
Do not use this code for otitis media with pus, chronic suppurative disease, or unspecified ear involvement. Check documentation if the chart does not confirm recurrence or the right side.
Coding tip
Confirm both recurrence and laterality in the provider note before assigning H65.04.
