Meningitis due to other nonbacterial organisms classified elsewhere

This code signifies inflammation of the meninges, the membranes surrounding the brain and spinal cord, specifically when caused by nonbacterial pathogens that are classified in other categories. This includes meningitis resulting from fungal, parasitic, or viral infections, excluding those with specific ICD-9 codes.

Apply this code when documentation confirms meningitis due to an identified nonbacterial organism, such as a specific fungus (e.g., Cryptococcus, Coccidioides), parasite, or a virus not otherwise specified. It is appropriate when the causative agent is known but does not have a more specific ICD-9 code for meningitis.

• Always attempt to identify the specific causative organism for more precise coding.
• Do not use this code for bacterial meningitis; refer to codes in the 320.xx series.
• Ensure documentation clearly states "meningitis" and specifies a nonbacterial etiology.
