Rubella meningitis

This code signifies inflammation of the meninges (the membranes surrounding the brain and spinal cord) specifically caused by the rubella virus. It represents a neurological complication arising from a rubella infection.

Assign this code when documentation clearly indicates meningitis as a direct result of rubella. This typically involves a confirmed rubella diagnosis alongside clinical signs and symptoms of meningitis, often supported by cerebrospinal fluid (CSF) analysis confirming viral etiology.

• Ensure documentation specifies rubella as the causative agent for the meningitis; otherwise, a non-specific viral meningitis code may be more appropriate.
• Do not confuse with congenital rubella syndrome manifestations, which have separate codes.
• Consider sequencing this code as the primary diagnosis if the meningitis is the reason for the encounter, with an additional code for the underlying rubella infection if still active.
