Yellow fever.
ICD-10 A98.5 is a billable code used to indicate a diagnosis of yellow fever..
Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus, which is transmitted by infected mosquitoes, primarily Aedes aegypti. The disease is endemic in tropical regions of Africa and South America. The clinical presentation of yellow fever can range from mild to severe, with symptoms typically appearing 3 to 6 days after infection. Initial symptoms include fever, chills, loss of appetite, muscle pain, and headache. In severe cases, patients may progress to a more serious phase characterized by abdominal pain, liver damage, and bleeding due to liver failure, which can lead to a high mortality rate. Diagnosis is primarily based on clinical history, including travel to endemic areas, and serological testing. Vaccination is the most effective preventive measure, and it is often required for travelers to certain regions. Given the potential for outbreaks, especially in unvaccinated populations, accurate coding and documentation are crucial for public health tracking and resource allocation.

Document the reason for testing and any relevant travel history.
Infectious disease specialists should ensure comprehensive documentation of clinical findings.
Yellow fever is primarily transmitted through the bite of infected Aedes mosquitoes, particularly Aedes aegypti.
