Mumps virus meningoencephalitis
ICD-10 B08.2 is a billable code used to indicate a diagnosis of mumps virus meningoencephalitis.
Mumps virus meningoencephalitis is a serious complication of mumps infection, characterized by inflammation of the brain and its surrounding membranes. The mumps virus, an RNA virus of the Paramyxoviridae family, primarily affects children but can occur in unvaccinated adults. Symptoms typically include fever, headache, vomiting, and signs of meningeal irritation such as neck stiffness. Neurological manifestations may vary from mild to severe, including seizures and altered consciousness. Diagnosis is confirmed through clinical evaluation, serological testing for mumps IgM antibodies, and sometimes lumbar puncture to analyze cerebrospinal fluid (CSF). The condition can lead to long-term complications such as hearing loss, cognitive impairment, and in rare cases, death. Vaccination with the MMR (measles, mumps, rubella) vaccine is crucial in preventing mumps and its complications, including meningoencephalitis. The incidence of mumps has significantly decreased in vaccinated populations, but outbreaks can still occur, particularly in communities with low vaccination rates.
