Influenza due to unidentified influenza virus w otitis media

This code signifies a patient presenting with influenza symptoms, where the specific influenza virus type has not been identified, and a co-occurring middle ear infection (otitis media). It indicates a viral respiratory illness complicated by an acute inflammatory process of the middle ear.

Apply this code when documentation confirms a diagnosis of influenza, but the physician has not specified the influenza virus as avian, novel, or other identified types. It is appropriate when otitis media is also diagnosed and clearly linked as a complication or co-occurrence with the influenza.

• Ensure the documentation explicitly states "influenza" and "otitis media" without identifying a specific influenza virus strain.
• Do not use if the influenza virus type (e.g., H1N1, H3N2) is known; a more specific influenza code would be required.
• Sequence this code as the primary diagnosis if the influenza is the reason for the encounter, followed by codes for specific symptoms if not inherent to influenza or otitis media.
