Tick-borne viral encephalitis
ICD-10 A83.0 is a billable code used to indicate a diagnosis of tick-borne viral encephalitis.
Tick-borne viral encephalitis (TBE) is a viral infection that affects the central nervous system, primarily transmitted through the bite of infected ticks, particularly the Ixodes ricinus and Ixodes persulcatus species. The disease is endemic in certain regions of Europe and Asia, where the virus is prevalent in wildlife, particularly in rodents and birds. Clinically, TBE can present in three phases: an initial febrile phase, followed by a symptom-free interval, and then a neurological phase characterized by meningoencephalitis. Symptoms may include fever, headache, nausea, vomiting, and neurological deficits such as confusion, seizures, or paralysis. The severity of the disease can vary, with some patients recovering fully while others may experience long-term neurological complications. Vaccination is available and recommended for individuals at high risk, such as those living in endemic areas or engaging in outdoor activities in these regions. Early diagnosis and supportive care are crucial for improving outcomes in affected patients.
Thorough documentation of travel history, exposure to ticks, and vaccination status.
Patients presenting with fever and neurological symptoms after travel to endemic areas.
Ensure that all relevant laboratory results and imaging studies are included in the documentation.
Detailed neurological examination findings and assessment of cognitive function.
Patients with acute onset of neurological symptoms following a febrile illness.
Document any long-term neurological deficits and rehabilitation needs.
Used when testing for TBE virus in patients with suspected encephalitis.
Document the clinical rationale for testing and any relevant patient history.
Infectious disease specialists should ensure that all relevant laboratory results are included.
Symptoms typically include fever, headache, nausea, vomiting, and neurological symptoms such as confusion, seizures, and paralysis.
Diagnosis is based on clinical symptoms, history of tick exposure, and serological testing for TBE virus antibodies.
Yes, a vaccine is available and recommended for individuals at high risk, particularly those living in or traveling to endemic areas.
