About the A96 Code Range
The ICD-10 code for arenaviral hemorrhagic fever and its specific types are used to identify infections caused by various arenaviruses that result in severe bleeding and systemic illness. These codes help distinguish between different arenaviral diseases like Junin hemorrhagic fever, Machupo hemorrhagic fever, and Lassa fever, as well as other less common arenaviral infections.
Code A96 covers arenaviral hemorrhagic fever broadly, while subcategories such as A96.0 specify Junin hemorrhagic fever, often called Argentinian hemorrhagic fever or Junin virus encephalitis. A96.1 identifies Machupo hemorrhagic fever (Bolivian hemorrhagic fever), linked to Machupo virus infections. The code A96.2 is used for Lassa fever, a well-known arenaviral infection. Further, A96.8 includes other arenaviral hemorrhagic fevers like South American, Venezuelan, and Lujo hemorrhagic fevers caused by viruses such as Guanarito, Sabia, and Chapare. Finally, A96.9 records unspecified arenaviral hemorrhagic fevers when the exact virus is unknown. These codes allow precise documentation for viral hemorrhagic fevers caused by arenaviruses, which is crucial for clinical care and epidemiological tracking.
