ICD-10 Code A92.2 – Venezuelan equine fever (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A92.2 – Venezuelan equine fever
What it is
A92.2 identifies Venezuelan equine fever, a mosquito-borne viral illness. Use it for confirmed or documented infection with this specific arboviral disease.
Clinical signs
Clinical features vary; refer to documentation. Typical descriptions include acute febrile illness with headache, malaise, and muscle pain, sometimes with neurologic or hemorrhagic involvement in severe cases.
When to use this code
Use A92.2 when the provider documents Venezuelan equine fever or Venezuelan equine encephalitis as the diagnosis. It may also apply when the record clearly identifies this arboviral infection without broader syndromic coding. Check documentation if the note only says viral fever or encephalitis.
Do not use for
Do not use this code for unspecified mosquito-borne viral fever, other arboviral infections, or encephalitis without a documented cause. If the organism is not named, code the documented condition instead.
Coding tip
Code the specific infection only when the provider names it; otherwise, use the most precise documented diagnosis and avoid assumptions.
