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.

Assign this code when documentation clearly indicates a diagnosis of meningitis due to Haemophilus influenzae. This typically follows laboratory confirmation of the bacterial pathogen from cerebrospinal fluid (CSF) analysis or blood cultures in a patient presenting with meningeal signs and symptoms.

• Always confirm the specific bacterial etiology; do not use for meningitis of unspecified bacterial origin.
• Code any associated neurological complications, such as hydrocephalus or cranial nerve palsies, separately.
• Distinguish from other forms of bacterial meningitis (e.g., meningococcal, pneumococcal) based on definitive lab results.
