Coxsackievirus as the cause of diseases classified elsewhere

This code identifies a coxsackievirus as the underlying etiology for a disease that is classified and coded elsewhere in ICD-10-CM. It signifies that a patient's primary diagnosis, such as myocarditis or meningitis, is directly attributable to a coxsackieviral infection. This code is never used as a primary diagnosis.

Apply this code when medical record documentation clearly states that a coxsackievirus is the causative agent for another specified condition. This typically occurs when a definitive laboratory test confirms the presence of coxsackievirus in conjunction with a related clinical manifestation. It should be used as a secondary diagnosis following the code for the specific disease caused by the virus.

• Always sequence this code after the code for the specific disease caused by the coxsackievirus (e.g., A87.0 for viral meningitis).
• Ensure documentation explicitly links the coxsackievirus to the "diseases classified elsewhere" to support its use.
• Do not use this code if the coxsackievirus infection is not causing a distinct, separately classified disease.
