Respiratory syncytial virus causing diseases classd elswhr

This code identifies Respiratory Syncytial Virus (RSV) as the underlying cause of a disease that is classified and coded elsewhere. It signifies that RSV is the etiologic agent responsible for a condition, but not one of the specific RSV-related respiratory infections (bronchiolitis, bronchitis, pneumonia) that have their own dedicated codes.

Use this code when documentation clearly states RSV as the cause of a condition that does not have a specific RSV-related code, such as otitis media due to RSV or conjunctivitis due to RSV. This code is always a secondary code, following the code for the manifestation. The medical record must explicitly link RSV to the "diseases classified elsewhere."

• Always sequence this code after the code for the specific manifestation caused by RSV.
• Carefully review the "Excludes1" notes to avoid coding this with specific RSV-related respiratory infections.
• Ensure the provider's documentation explicitly states RSV as the cause of the other condition, not just a co-occurring infection.
