Hemophilus meningitis

This code represents an acute inflammation of the meninges, the protective membranes surrounding the brain and spinal cord, specifically caused by Haemophilus influenzae bacteria. It is a serious bacterial infection that can lead to severe neurological complications if not promptly treated.

Use this code when documentation clearly indicates a diagnosis of meningitis due to Haemophilus influenzae. This diagnosis is typically confirmed by cerebrospinal fluid (CSF) analysis showing bacterial growth of H. influenzae and clinical signs of meningitis.

• Ensure the causative organism is explicitly identified as Haemophilus influenzae; do not use for meningitis due to other bacterial agents.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Do not confuse with viral meningitis or meningitis of unspecified etiology; specific documentation of Haemophilus is required.
