ICD-10 Code H65.23 – Chronic serous otitis media, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.23 – Chronic serous otitis media, bilateral
What it is
H65.23 identifies chronic fluid buildup behind both eardrums without acute infection. It is used when the middle-ear effusion persists over time and affects both ears.
Clinical signs
Common findings include bilateral middle-ear effusion, dull or retracted tympanic membranes, and conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use H65.23 when the record clearly documents chronic serous otitis media in both ears, or persistent bilateral middle-ear effusion. You should choose it when the clinician describes a noninfectious, ongoing effusion rather than an acute ear infection. Check documentation if laterality or chronicity is unclear.
Do not use for
Do not use this code for acute otitis media, suppurative disease, or unilateral serous otitis media. If the note does not confirm bilateral chronic involvement, check documentation.
Coding tip
Confirm both chronicity and bilateral laterality in the assessment before assigning H65.23.
