Venezuelan equine fever

This code represents Venezuelan equine encephalomyelitis (VEE), an arboviral disease primarily affecting equids but transmissible to humans. It is characterized by fever, headache, myalgia, and in severe cases, encephalitis, particularly in children.

Use this code for confirmed or suspected cases of Venezuelan equine fever in human patients. Documentation should clearly indicate a diagnosis of VEE, often supported by laboratory confirmation (e.g., serology, PCR) or strong epidemiological links to an outbreak or endemic area.

• Ensure documentation specifies "Venezuelan" equine fever to differentiate from other equine encephalitides.
• Consider additional codes for specific neurological manifestations (e.g., encephalitis, meningitis) if documented.
• This is a legacy ICD-9-CM code; for current coding, refer to the appropriate ICD-10-CM code (A92.2).
