Cryptococcal meningitis

This code represents an infection of the meninges and cerebrospinal fluid (CSF) caused by the fungus Cryptococcus neoformans or Cryptococcus gattii. It is a serious central nervous system infection, often seen in immunocompromised individuals.

Use this code when documentation clearly indicates a diagnosis of meningitis specifically attributed to Cryptococcus. This diagnosis is typically confirmed by laboratory identification of Cryptococcus in CSF or tissue samples.

• Always confirm the causative organism is Cryptococcus; do not use for unspecified fungal meningitis.
• Consider co-occurring conditions, especially immunocompromised states (e.g., HIV), and code them appropriately.
• Review documentation for specific manifestations or complications of the meningitis that may require additional codes.
