Sarcoid meningitis

This code represents inflammation of the meninges (the membranes surrounding the brain and spinal cord) specifically caused by sarcoidosis. It indicates neurological involvement of sarcoidosis, which can manifest with various symptoms depending on the affected areas of the central nervous system.

Use this code when documentation explicitly states a diagnosis of sarcoid meningitis or neurosarcoidosis affecting the meninges. This diagnosis is typically supported by neurological examination findings, imaging (e.g., MRI of the brain/spine), and cerebrospinal fluid analysis consistent with sarcoidosis.

• Always confirm the specific neurological manifestation of sarcoidosis; do not use this code for other forms of neurosarcoidosis (e.g., sarcoid neuropathy).
• Ensure documentation clearly links the meningitis to sarcoidosis; if the etiology is unknown or different, a more general meningitis code may be appropriate.
• Consider sequencing this code after the primary sarcoidosis code (D86.9) if the meningitis is a manifestation of a systemic sarcoidosis.
