Meningitis due to echo virus

This code identifies inflammation of the meninges, the protective membranes surrounding the brain and spinal cord, specifically caused by an echovirus infection. Echoviruses are a common cause of viral meningitis, which is typically less severe than bacterial meningitis.

Assign this code when documentation explicitly states a diagnosis of meningitis and laboratory confirmation or strong clinical suspicion points to an echovirus as the causative agent. This code is appropriate for both acute and subacute presentations of echovirus-induced meningitis.

• Always seek definitive documentation of the causative organism. If the viral agent is unspecified, use codes for viral meningitis, unspecified.
• Do not confuse with meningitis due to other specific viral agents (e.g., mumps, herpes simplex).
• Sequence as the primary diagnosis when meningitis is the reason for the encounter.
