Mosquito-borne hemorrhagic fever

This code identifies a severe viral infection transmitted by mosquitoes, characterized by fever and hemorrhagic manifestations such as bleeding under the skin, from mucous membranes, or internal organs. It represents a systemic illness that can range from mild to life-threatening.

Assign this code for confirmed cases of hemorrhagic fever where the vector is identified as a mosquito. Documentation should clearly indicate the presence of hemorrhagic symptoms in conjunction with a diagnosis of a mosquito-borne viral infection, such as dengue hemorrhagic fever or yellow fever.

• Differentiate from other viral hemorrhagic fevers not transmitted by mosquitoes (e.g., Ebola, Marburg).
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Ensure documentation specifies "hemorrhagic" to support the use of this specific code rather than a general mosquito-borne fever.
