Coccidioidomycosis meningitis

This code represents an infection of the meninges (membranes surrounding the brain and spinal cord) caused by the fungus Coccidioides. It is a severe manifestation of coccidioidomycosis, often presenting with symptoms such as headache, fever, stiff neck, and altered mental status.

Use this code when documentation explicitly states a diagnosis of coccidioidomycosis affecting the meninges. This typically occurs in patients with a history of exposure to Coccidioides in endemic areas, presenting with neurological symptoms. Supporting documentation includes positive CSF fungal cultures or serology for Coccidioides, along with clinical signs of meningitis.

• Ensure documentation specifies "meningitis" and not just a general coccidioidomycosis infection.
• Do not confuse with other fungal meningitides; confirm the causative organism is Coccidioides.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated neurological complications.
