What condition does meningitis describe?

Meningitis is defined as the inflammation of the meninges, which are the protective membranes covering the brain and spinal cord. This condition can be caused by various infectious agents, including viruses, bacteria, and fungi. The inflammation can lead to a range of symptoms such as fever, headache, and neck stiffness, and can potentially result in serious complications if not treated promptly.

The correct identification as inflammation specifically targets the membranes that cover the central nervous system, distinguishing it from other conditions affecting the spinal cord or brain tissue directly. Understanding this definition is crucial for medical coding and documentation, as treatment protocols and severity of the condition may vary significantly based on the underlying cause of the meningitis.
