Otitis media in diseases classified elsewhere, right ear

This diagnosis code signifies inflammation of the middle ear in the right ear, specifically when it is a manifestation or complication of another underlying systemic disease. It indicates that the otitis media is secondary to a primary condition classified elsewhere in the ICD-10-CM system, rather than being a standalone primary ear infection.

Use this code when documentation clearly links right-sided otitis media to an underlying systemic disease, such as measles, influenza, or another infectious or inflammatory condition. The medical record should explicitly state "otitis media secondary to [disease]" or "otitis media in [disease]" affecting the right ear.

• Always sequence the underlying systemic disease first, followed by this code for the otitis media.
• Ensure the documentation specifies "right ear" and clearly establishes the causal link to another disease.
• Do not use this code for acute or chronic otitis media without an identified underlying systemic disease; use codes from the H65 or H66 series instead.
