Arenaviral hemorrhagic fever, unspecified

This code signifies a severe, acute viral infection characterized by fever, hemorrhage, and multi-organ involvement, caused by an Arenavirus. It represents a broad category when the specific type of Arenaviral hemorrhagic fever is not documented or known. These infections are zoonotic, often transmitted through rodent excreta.

This code is appropriate for cases where a patient presents with symptoms consistent with a hemorrhagic fever, and laboratory testing confirms an Arenavirus infection, but the specific Arenavirus (e.g., Lassa, Junin, Machupo) is not identified. It should be used when the provider's documentation clearly states "Arenaviral hemorrhagic fever, unspecified" or similar terminology indicating the general viral family without further specificity.

• Avoid using this code if a more specific Arenaviral hemorrhagic fever (e.g., Lassa fever, A96.2) is documented.
• Always review documentation for the specific Arenavirus to ensure the most precise code is selected.
• Consider additional codes for associated symptoms or complications, such as hemorrhage or organ failure.
