2025 ICD-10-CM code A84.1
Central European tick-borne encephalitis (TBE-Eu) is a viral infection causing inflammation of the brain.
Medical necessity for diagnostic testing and treatment is established by the signs, symptoms, and risk factors associated with TBE-Eu exposure. Severity of symptoms dictates the level of care required.
Clinicians diagnose TBE-Eu based on patient history, physical and neurological examinations, and laboratory tests.Imaging studies (CT, MRI, EEG) may also be used.Treatment is primarily supportive, including rest, fluids, pain relief, and in severe cases, corticosteroids to reduce brain inflammation.
- Certain infectious and parasitic diseases (A00-B99)
- Viral and prion infections of the central nervous system (A80-A89)
In simple words: Central European tick-borne encephalitis (TBE) is a brain infection spread by infected ticks.It can cause fever, headache, stiff neck, and in severe cases, brain swelling, confusion, and seizures.
Central European tick-borne encephalitis (TBE-Eu) is an inflammation of the brain caused by a specific tick-borne encephalitis virus (TBEV-Eu) found in parts of Europe. It is generally considered less severe than Far Eastern tick-borne encephalitis (TBE-FE), but unlike TBE-FE, TBE-Eu tends to be more severe in adults than in children.
Example 1: A 50-year-old hiker presents with fever, headache, stiff neck, and fatigue after a recent hiking trip in Austria.Blood tests confirm TBE-Eu infection., A child develops mild flu-like symptoms after playing in a wooded area in Germany.TBE-Eu is considered in the differential diagnosis., A patient presents with seizures and altered mental status after consuming unpasteurized goat milk in a TBE-Eu endemic region.
Documentation should include patient history (including exposure to ticks or consumption of unpasteurized dairy products), physical and neurological exam findings, laboratory results confirming TBE-Eu infection (e.g., positive IgM antibodies), and imaging findings.
