Yellow fever, unspecified

This code represents a severe, acute viral hemorrhagic disease characterized by fever, jaundice, hemorrhage, and kidney involvement, caused by the yellow fever virus. It is transmitted by mosquitoes, primarily Aedes aegypti.

Use this code when the patient presents with symptoms consistent with yellow fever, and the specific type or manifestation of the disease is not documented or is unknown. This code is appropriate for initial diagnosis when laboratory confirmation is pending or unavailable, or when the physician's documentation simply states "yellow fever" without further specificity.

• Only use this code when the documentation explicitly states "unspecified" or provides no further detail regarding the yellow fever type.
• Avoid using this code if more specific documentation (e.g., yellow fever with liver involvement) is available; look for more precise codes.
• Ensure documentation supports a confirmed or suspected diagnosis of yellow fever, not just general fever and jaundice.
