Other arenaviral hemorrhagic fevers

This code represents a group of severe viral infections caused by various arenaviruses, excluding Lassa fever, that manifest with hemorrhagic symptoms. These fevers are characterized by fever, malaise, myalgia, and often progress to include petechiae, ecchymoses, and internal bleeding, potentially leading to shock and multi-organ failure.

Use this code for documented cases of arenaviral hemorrhagic fevers where the specific causative arenavirus is identified but is not Lassa virus, or when the specific type of arenaviral hemorrhagic fever is not otherwise specified. Documentation should clearly indicate an arenaviral infection with hemorrhagic manifestations, excluding Lassa.

• Ensure documentation specifies "other" arenaviral hemorrhagic fever or identifies a specific arenavirus not classified elsewhere.
• Do not use this code for Lassa fever (A96.2), which has its own specific code.
• Code any associated complications, such as shock or organ failure, in addition to this primary diagnosis.
