Arenaviral hemorrhagic fever

This code represents a severe, acute viral infection caused by an Arenavirus, characterized by fever, malaise, and hemorrhagic manifestations such as petechiae, ecchymoses, and internal bleeding. These infections can lead to multi-organ failure and have a high mortality rate.

Apply this code for confirmed or highly suspected cases of hemorrhagic fever specifically attributed to an Arenavirus, such as Lassa fever or Argentine hemorrhagic fever. Documentation should clearly indicate the diagnosis of an arenaviral infection with associated hemorrhagic symptoms.

• Differentiate from other viral hemorrhagic fevers (e.g., Ebola, Marburg) which have distinct codes.
• Ensure documentation specifies "arenaviral" to support the use of this specific code.
• Code any associated complications (e.g., renal failure, shock) separately.
