Mumps virus meningoencephalitis
ICD-10 B08.1 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 as well. Symptoms typically include fever, headache, vomiting, and signs of meningeal irritation such as neck stiffness. Neurological manifestations can range from mild confusion to severe encephalitis, which may lead to long-term complications such as seizures, hearing loss, or cognitive impairment. Diagnosis is usually confirmed through clinical evaluation and laboratory tests, including serological assays for mumps IgM antibodies or PCR testing of cerebrospinal fluid (CSF). Vaccination with the MMR (measles, mumps, rubella) vaccine has significantly reduced the incidence of mumps and its complications, including meningoencephalitis. However, outbreaks can still occur, particularly in populations with low vaccination rates. Prompt recognition and management are crucial to minimize the risk of severe outcomes.
Complete vaccination history, clinical symptoms, and laboratory results.
Children presenting with fever, headache, and signs of meningitis.
Consideration of recent outbreaks and vaccination rates in the community.
Detailed history of exposure, laboratory confirmation, and treatment plans.
Adults with neurological symptoms and history of mumps infection.
Need for thorough differential diagnosis to rule out other viral infections.
Used when confirming mumps virus in a patient with meningoencephalitis.
Laboratory results must be documented in the medical record.
Infectious disease specialists may order this test more frequently.
Common symptoms include fever, headache, vomiting, neck stiffness, and neurological signs such as confusion or seizures.
Vaccination with the MMR vaccine is the most effective way to prevent mumps and its complications, including meningoencephalitis.
