ICD-10 Code H65.2 – Chronic serous otitis media (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H65.2 – Chronic serous otitis media
What it is
H65.2 identifies chronic serous otitis media, a persistent middle-ear effusion without acute infection. Use it when documentation describes ongoing fluid behind the eardrum.
Clinical signs
Typical findings include a dull or retracted tympanic membrane, reduced mobility, and conductive hearing loss. Clinical features vary; refer to documentation.
When to use this code
Use H65.2 when the record clearly states chronic serous otitis media, chronic effusion, or persistent noninfectious middle-ear fluid. It fits follow-up visits and evaluations for hearing problems when the condition is documented as chronic. If the note does not specify chronicity, check documentation.
Do not use for
Do not use this code for acute otitis media, suppurative otitis media, or ear pain without documented middle-ear effusion. Check documentation if the diagnosis is uncertain.
Coding tip
Code H65.2 only when chronic serous otitis media is explicitly documented; do not assume it from nonspecific ear symptoms.
