Epidemic cerebrospinal meningitis

Code Description

ICD-10 A88.1 is a billable code used to indicate a diagnosis of epidemic cerebrospinal meningitis.

Key Diagnostic Point:

Epidemic cerebrospinal meningitis is a severe and potentially life-threatening infection of the protective membranes covering the brain and spinal cord, primarily caused by viral pathogens. This condition is characterized by inflammation of the meninges, leading to symptoms such as fever, headache, neck stiffness, and altered mental status. The viral etiology often includes enteroviruses, mumps virus, and herpes simplex virus, among others. Epidemic outbreaks can occur in crowded settings, such as schools or military barracks, where transmission is facilitated. Neurological complications may arise, including seizures, hydrocephalus, and long-term cognitive deficits. Vaccination status plays a crucial role in prevention; vaccines against specific viral pathogens can significantly reduce the incidence of meningitis. Early diagnosis and management are essential to mitigate complications and improve outcomes.
