ICD-10 Code H65.32 – Chronic mucoid otitis media, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.32 – Chronic mucoid otitis media, left ear
What it is
H65.32 identifies chronic mucoid otitis media in the left ear. Use it when the middle ear contains persistent nonpurulent fluid, with the condition documented as chronic and limited to the left side.
Clinical signs
Common findings include a dull or retracted tympanic membrane, middle-ear effusion, and hearing difficulty. Clinical features vary; refer to documentation.
When to use this code
Use H65.32 when the provider documents chronic mucoid otitis media affecting only the left ear. It is appropriate for follow-up visits, chronic effusion notes, or ENT assessments that clearly specify the left ear and a mucoid, noninfectious middle-ear process.
Do not use for
Do not use this code for acute otitis media, suppurative otitis media, or unspecified ear laterality. Check documentation if the record does not clearly state chronic mucoid disease of the left ear.
Coding tip
Confirm both chronicity and laterality in the note before assigning H65.32.
