Chronic serous otitis media, bilateral

This code signifies a persistent, non-infectious inflammation of the middle ear in both ears, characterized by the presence of serous (thin, watery) fluid behind the eardrum. This fluid accumulation is chronic, meaning it has been present for an extended period, typically three months or longer.

Apply this code when documentation clearly indicates bilateral chronic serous otitis media, often presenting with hearing loss, aural fullness, or recurrent effusions. This diagnosis is typically supported by otoscopic examination revealing fluid behind both tympanic membranes, and potentially by audiometry confirming conductive hearing loss.

• Differentiate from acute serous otitis media (H65.03) or other forms of chronic otitis media (e.g., mucoid, suppurative).
• Ensure the documentation explicitly states "bilateral" and "chronic" to support this specific code.
• Consider co-reporting with codes for associated symptoms like conductive hearing loss (H90.0x) if documented.
