Japanese encephalitis.
ICD-10 A83.1 is a billable code used to indicate a diagnosis of japanese encephalitis..
Japanese encephalitis (JE) is a viral infection caused by the Japanese encephalitis virus (JEV), which is primarily transmitted through the bite of infected mosquitoes, particularly in rural agricultural areas of Asia. The disease can lead to severe neurological complications, including encephalitis, which is characterized by inflammation of the brain. Symptoms typically begin with fever, headache, and vomiting, progressing to neurological manifestations such as seizures, altered mental status, and paralysis. The incidence of JE is highest in children, and while many infections are asymptomatic, a significant proportion can lead to severe outcomes, including death or long-term neurological deficits. Vaccination is the most effective preventive measure, especially for individuals living in or traveling to endemic areas. The JE vaccine is recommended for those at risk, including travelers to high-risk regions, and is typically administered in a two-dose series. Early diagnosis and supportive care are crucial for improving outcomes in affected individuals.
Detailed travel history, vaccination records, and clinical symptoms.
Patients presenting with fever and neurological symptoms after travel to endemic areas.
Ensure vaccination status is documented to support coding.
Neurological examination findings, imaging results, and treatment plans.
Patients with acute encephalitis symptoms requiring neurological evaluation.
Document all neurological deficits and complications for accurate coding.
Used when testing for JE in patients with suspected infection.
Document the reason for testing and clinical symptoms.
Infectious disease specialists should ensure comprehensive documentation of travel history.
Japanese encephalitis is primarily transmitted through the bite of infected mosquitoes, particularly in rural areas where the virus is endemic.
Vaccination is the most effective way to prevent Japanese encephalitis, especially for individuals traveling to endemic regions. Additionally, using mosquito repellent and protective clothing can help reduce the risk of infection.
