Machupo hemorrhagic fever

This code represents Machupo hemorrhagic fever, a severe, acute viral illness caused by the Machupo virus, an RNA virus of the Arenaviridae family. It is characterized by fever, malaise, myalgia, and hemorrhagic manifestations such as petechiae, ecchymoses, and gastrointestinal bleeding, often leading to shock and multi-organ failure. The disease is endemic to specific regions of Bolivia.

This code is used when a patient is diagnosed with Machupo hemorrhagic fever, confirmed through laboratory testing (e.g., PCR, serology) or strong epidemiological links and characteristic clinical presentation. Documentation should clearly indicate the specific diagnosis of Machupo hemorrhagic fever, distinguishing it from other viral hemorrhagic fevers.

• Ensure documentation specifies "Machupo" to differentiate from other viral hemorrhagic fevers.
• Do not confuse with other viral hemorrhagic fevers like Lassa fever or Ebola, which have distinct codes.
• Sequence this code as the primary diagnosis when it is the reason for the encounter.
