ICD-10 Code H65.30 – Chronic mucoid otitis media, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.30 – Chronic mucoid otitis media, unspecified ear
What it is
H65.30 identifies chronic mucoid otitis media when the affected ear is not specified. It refers to persistent middle-ear fluid that is thick or mucoid rather than acute infection.
Clinical signs
Typical findings include a long-standing middle-ear effusion, ear fullness, and reduced hearing. Clinical features vary; refer to documentation for evidence of chronicity and the unspecified ear.
When to use this code
Use this code when the record documents chronic mucoid otitis media but does not name the right or left ear. It also fits when the clinician clearly describes persistent mucoid effusion of the middle ear. If the note specifies a side, code that laterality instead.
Do not use for
Do not use this code for acute otitis media, serous otitis media, or cases where the ear is documented as right or left. Check documentation if the type of effusion or chronic status is unclear.
Coding tip
Confirm both chronicity and laterality in the chart before assigning H65.30.
