Chronic mucoid otitis media, right ear

This code signifies a persistent, non-infectious inflammation of the middle ear in the right ear, characterized by the presence of thick, non-purulent fluid (mucus). This condition is often referred to as "glue ear" due to the viscous nature of the fluid, which can impair hearing.

Apply this code when documentation specifies chronic mucoid otitis media affecting the right ear. This diagnosis is typically made after otoscopic examination revealing a dull, retracted, or bulging tympanic membrane with evidence of thick fluid behind it, and often confirmed by tympanometry.

• Ensure the documentation clearly specifies "chronic" and "mucoid" to differentiate from acute or serous forms.
• Laterality is crucial; verify the right ear is explicitly stated.
• Do not confuse with H65.21 (Chronic serous otitis media, right ear), which involves thinner, watery fluid.
