Japanese encephalitis virus disease
ICD-10 A83.6 is a billable code used to indicate a diagnosis of japanese encephalitis virus disease.
Japanese encephalitis (JE) is a viral infection caused by the Japanese encephalitis virus (JEV), primarily transmitted through the bite of infected mosquitoes, particularly in rural areas of Asia and the Western Pacific. The disease can lead to severe neurological complications, including encephalitis, which is characterized by inflammation of the brain. Symptoms may range from mild flu-like signs to severe neurological manifestations such as seizures, altered mental status, and coma. The incubation period typically lasts from 5 to 15 days, and while many infections are asymptomatic, approximately 1 in 250 infections can result in severe disease. Neurological complications can include long-term cognitive deficits, motor dysfunction, and behavioral changes. Vaccination is the most effective preventive measure against JE, especially for individuals traveling to endemic areas or those living in high-risk regions. The vaccine is recommended for children and adults who may be exposed to the virus. Accurate coding of JE is crucial for public health tracking and resource allocation, as well as for ensuring appropriate patient management and follow-up.
Detailed history of exposure, vaccination status, and clinical presentation.
Patients presenting with fever, altered mental status, and neurological symptoms after travel to endemic areas.
Ensure thorough documentation of travel history and vaccination to support coding.
Comprehensive neurological examination findings and imaging results.
Patients with severe neurological deficits following a febrile illness.
Document all neurological assessments and any complications for accurate coding.
Used to confirm diagnosis in suspected cases of JE.
Document the reason for testing and clinical findings.
Infectious disease specialists should ensure comprehensive documentation of exposure history.
Symptoms can range from mild flu-like signs to severe neurological manifestations, including fever, headache, seizures, and altered mental status. Many cases are asymptomatic.
Diagnosis is based on clinical presentation, history of exposure to endemic areas, and laboratory tests such as serology or PCR to confirm the presence of the virus.
Yes, there is a vaccine available that is recommended for individuals traveling to or living in endemic areas.
There is no specific antiviral treatment for JE; management focuses on supportive care, including hospitalization for severe cases.
