Actinomycotic meningitis

This code represents a rare but serious infection of the meninges (membranes surrounding the brain and spinal cord) caused by Actinomyces bacteria. It typically manifests as chronic meningitis, often with abscess formation, and can lead to significant neurological deficits if untreated.

Assign this code when documentation clearly indicates a diagnosis of meningitis specifically attributed to Actinomyces species. This diagnosis is typically confirmed through microbiological culture of cerebrospinal fluid (CSF) or biopsy of affected tissue.

• Ensure documentation specifies Actinomyces as the causative organism for meningitis; otherwise, use a more general meningitis code.
• Look for associated conditions like brain abscesses or osteomyelitis, which may require additional coding.
• Do not confuse with fungal meningitis; Actinomyces are bacteria, not fungi.
