Unsp enterovirus as the cause of diseases classd elswhr

This code identifies an unspecified enterovirus as the underlying cause of a disease process that is classified and coded elsewhere. It signifies that an enteroviral infection is confirmed, but the specific type of enterovirus (e.g., poliovirus, coxsackievirus, echovirus) has not been identified.

Use this code when documentation clearly states an enteroviral infection is the etiology of another condition (e.g., enteroviral meningitis, enteroviral rash), but the specific enterovirus is not specified. This code is always a secondary diagnosis, following the code for the manifestation.

• Always sequence this code after the code for the specific disease manifestation caused by the enterovirus.
• Avoid using this code if a more specific enterovirus (e.g., coxsackievirus) is documented; instead, use the appropriate specific B97.1- subcategory.
• Ensure the medical record explicitly links the enterovirus to the "diseases classified elsewhere" to support its use as an etiology code.
