Meningitis due to adenovirus

This code signifies inflammation of the meninges, the protective membranes surrounding the brain and spinal cord, specifically caused by an adenovirus infection. It represents a viral form of meningitis where adenovirus has been identified as the causative agent.

Use this code when documentation clearly indicates a diagnosis of meningitis and laboratory findings or clinical assessment confirm adenovirus as the etiologic agent. This typically applies to cases of viral meningitis where specific viral identification has been performed.

• Ensure documentation specifies adenovirus as the cause; otherwise, an unspecified viral meningitis code may be more appropriate.
• Do not confuse with bacterial or fungal meningitis, which have distinct codes.
• Consider sequencing this code after the primary manifestation if the meningitis is a complication of a more generalized adenovirus infection.
