Influenza due to oth ident influenza virus w oth manifest

This code signifies an influenza infection caused by a specifically identified influenza virus, other than avian or novel H1N1, presenting with symptoms beyond typical respiratory involvement. This could include systemic complications or manifestations in other organ systems.

Utilize this code when documentation confirms an influenza infection due to a laboratory-confirmed influenza virus type (e.g., Influenza B, H3N2) and the patient exhibits non-respiratory symptoms or complications, such as myositis, encephalopathy, or cardiac involvement. The physician's notes must clearly link these manifestations to the influenza infection.

• Ensure the documentation specifies an "other identified influenza virus" and not avian or novel H1N1, which have their own specific codes.
• Do not use this code for uncomplicated influenza; those cases typically fall under J10.1 or J10.0.
• Always sequence the influenza code first, followed by codes for any associated manifestations or complications.
