Meningococcal meningitis

This code represents an acute bacterial infection of the meninges caused by Neisseria meningitidis. It is a severe form of meningitis characterized by inflammation of the membranes surrounding the brain and spinal cord, often leading to rapid onset of symptoms and potential for serious complications.

Use this code for confirmed cases of meningococcal meningitis based on cerebrospinal fluid (CSF) analysis or blood cultures identifying Neisseria meningitidis. Documentation should clearly indicate the specific pathogen responsible for the meningitis.

• Differentiate from other bacterial or viral meningitides; ensure the pathogen Neisseria meningitidis is explicitly documented.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
• Review for any associated complications, such as hydrocephalus, seizures, or sepsis, and code them accordingly.
