Streptococcal meningitis

This code represents an inflammation of the meninges, the membranes surrounding the brain and spinal cord, specifically caused by a Streptococcus bacterial infection. This is a severe form of bacterial meningitis that can lead to significant neurological complications if not promptly treated.

Assign this code when documentation clearly states a diagnosis of meningitis due to Streptococcus species. This typically follows laboratory confirmation of streptococcal infection from cerebrospinal fluid (CSF) analysis or blood cultures in a patient presenting with meningeal signs.

• Always confirm the specific bacterial pathogen; do not use for meningitis due to other bacterial types.
• If the specific Streptococcus species is identified (e.g., Streptococcus pneumoniae), a more specific code (e.g., G00.1) should be used.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated neurological complications.
