Chronic allergic otitis media, right ear

This diagnosis code signifies a persistent inflammatory condition of the right middle ear, specifically attributed to an allergic reaction. It indicates a chronic, rather than acute, presentation of otitis media where an allergen is the underlying cause.

This code is appropriate when documentation clearly states chronic allergic otitis media affecting the right ear. Supporting documentation should include a history of recurrent or persistent middle ear inflammation, evidence of an allergic etiology (e.g., positive allergy testing, response to antihistamines), and laterality specified as the right ear.

• Ensure documentation explicitly states "chronic" and "allergic" to differentiate from acute or non-allergic forms of otitis media.
• Verify laterality; this code is specific to the right ear. Use the appropriate code for the left or bilateral ear if indicated.
• Consider coding any identified allergic rhinitis or other allergic conditions as additional diagnoses, if present and documented.
