Crimean-Congo hemorrhagic fever

This code represents a severe, often fatal, viral hemorrhagic fever caused by the Crimean-Congo hemorrhagic fever virus (CCHFV). It is characterized by sudden onset of fever, myalgia, headache, and can progress to hemorrhagic manifestations such as petechiae, ecchymoses, epistaxis, and gastrointestinal bleeding. The disease can lead to multi-organ failure and a high mortality rate.

Use this code for confirmed cases of Crimean-Congo hemorrhagic fever based on laboratory testing (e.g., PCR, serology) or strong clinical suspicion in an endemic area. Documentation should clearly indicate the diagnosis of CCHF, including symptoms consistent with the disease and any relevant travel history or exposure to ticks or livestock.

• Ensure documentation specifies "Crimean-Congo" to differentiate from other hemorrhagic fevers.
• Do not confuse with other viral hemorrhagic fevers (e.g., Ebola, Marburg) which have distinct codes.
• Code any associated complications, such as organ failure or shock, in addition to the primary diagnosis.
