Echovirus as the cause of diseases classified elsewhere

This code identifies an illness or condition caused by an Echovirus infection, where the primary manifestation of the disease is classified under a different ICD-10-CM code. It signifies the etiologic agent responsible for a separate, specified disease.

Apply this code as a secondary diagnosis when documentation clearly links an Echovirus infection to a specific disease classified elsewhere, such as viral meningitis (G03.0) or myocarditis (I40.1). The medical record must explicitly state "Echovirus" as the causative agent for the co-occurring condition.

• Always sequence this code after the code for the primary disease manifestation.
• Ensure the documentation explicitly names Echovirus as the pathogen; do not assume based on general viral symptoms.
• Distinguish from other viral agents; this code is specific to Echovirus.
