2025 ICD-10-CM code A83.6
Rocio virus disease, a mosquito-borne flavivirus infection causing encephalitis (brain inflammation).
Medical necessity for diagnostic testing and treatment is established by the presence of signs and symptoms consistent with Rocio virus disease, especially in individuals with potential exposure in endemic areas.
Clinicians diagnose Rocio virus disease based on patient history, physical and neurological exams, and imaging (CT, EEG, MRI). CSF examination confirms the diagnosis. Treatment focuses on managing symptoms with corticosteroids, rest, fluids, pain relievers, and sedatives. Severe cases require hospitalization.
- Certain infectious and parasitic diseases (A00-B99)
- Viral and prion infections of the central nervous system (A80-A89)
In simple words: Rocio virus disease is a brain infection spread by mosquitoes. It can cause fever, headache, stiff neck, and in severe cases, confusion, seizures, or coma.
Rocio virus disease is characterized by inflammation of the brain due to infection with the Rocio virus (RV), a flavivirus transmitted by mosquitoes. Symptoms range from fever, headache, and stiff neck to severe neurological manifestations like confusion, seizures, and coma.
Example 1: A patient presents with fever, headache, stiff neck, and lethargy after recent travel to Brazil. Imaging reveals brain inflammation, and CSF analysis confirms Rocio virus infection., A patient develops seizures, confusion, and partial paralysis following mosquito bites in a rural area known for Rocio virus transmission., A child experiences nausea, vomiting, and high fever, followed by rapid neurological deterioration. Rocio virus disease is confirmed through laboratory testing.
Documentation should include travel history, symptom onset, physical and neurological exam findings, imaging results (CT, EEG, MRI), and CSF analysis confirming Rocio virus infection.
