Influenza due to oth ident influenza virus w oth pneumonia

This code signifies a patient presenting with pneumonia that is specifically caused by an influenza virus other than the commonly identified seasonal strains (e.g., H1N1, H3N2, or avian flu strains like H5N1). It indicates a confirmed influenza infection where the specific viral type has been identified, and this infection has led to a specified type of pneumonia.

Use this code when documentation clearly states a diagnosis of pneumonia directly attributed to an influenza virus, and the specific influenza virus is identified as "other" than the standard seasonal or avian types. This typically requires laboratory confirmation of the influenza strain and a clear link between the influenza and the pneumonia.

• Ensure the medical record specifies "other identified influenza virus" and a diagnosis of pneumonia.
• Do not use this code if the influenza virus type is unspecified or if the pneumonia is not directly linked to the influenza.
• Always sequence the influenza code first, followed by codes for any associated complications or manifestations, if applicable.
