Benign recurrent meningitis [Mollaret]

This code represents a rare, self-limiting form of aseptic meningitis characterized by recurrent episodes of meningeal inflammation. Patients experience sudden onset of fever, headache, neck stiffness, and photophobia, typically resolving spontaneously within a few days. The condition is benign and does not cause permanent neurological damage.

Use this code for patients presenting with documented recurrent episodes of meningitis where infectious causes have been ruled out, and the clinical picture aligns with Mollaret's meningitis. Documentation should clearly indicate the recurrent nature of the aseptic meningitis and the absence of a persistent underlying cause.

• Ensure documentation explicitly states "recurrent" and "benign" or "Mollaret's" meningitis.
• Differentiate from other forms of aseptic meningitis (G03.0, G03.1) which are not recurrent or have a known underlying cause.
• Do not use if an infectious agent is identified as the cause of the meningitis.
