ICD-10 Code H65.117 – Acute and subacute allergic otitis media (mucoid) (sanguinous) (serous), recurrent, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.117 – Acute and subacute allergic otitis media (mucoid) (sanguinous) (serous), recurrent, unspecified ear
What it is
This code identifies recurrent allergic otitis media with fluid in the middle ear, described as mucoid, sanguinous, or serous, when the affected ear is not specified. Use it when documentation states the condition is acute or subacute and recurrent.
Clinical signs
Typical findings include middle-ear effusion and symptoms such as ear fullness, hearing change, or pressure. Clinical features vary; refer to documentation for the exact ear involved and the type of effusion noted.
When to use this code
Use this code when the record clearly documents recurrent allergic otitis media and does not identify the left or right ear. It also fits when the provider specifies mucoid, sanguinous, or serous fluid and labels the episode acute or subacute. Check documentation if the note is ambiguous.
Do not use for
Do not use it for otitis media without an allergic cause, or when the ear laterality is documented. Avoid this code if the chart describes a different otitis media type or does not support recurrence.
Coding tip
Confirm both recurrence and unspecified ear before assigning H65.117.
