2025 ICD-10-CM code A92.9
Mosquito-borne viral fever, unspecified.
The diagnosis of a mosquito-borne viral fever requires clinical findings and a history suggesting mosquito exposure. If a specific virus is identified, a more specific code should be used.
Diagnosis is based on history of exposure, physical examination, signs, and symptoms. Laboratory tests such as CBC, PCR, and ELISA may be helpful. Treatment is usually symptomatic and includes rest, fluids, antipyretics, and pain killers.
In simple words: This code represents a fever caused by a virus transmitted through a mosquito bite, where the specific virus isn't identified.
Mosquito-borne viral fevers refer to viral illnesses transmitted to humans by the bite of infected mosquitoes. This code is used when the provider does not specify the type of mosquito-borne viral fever.
Example 1: A patient presents with fever, chills, headache, joint and muscle aches, nausea, and vomiting after a recent trip to a mosquito-prone area. The provider suspects a mosquito-borne viral fever but cannot confirm a specific type, making A92.9 appropriate. , A patient residing in a region known for mosquito-borne illnesses develops a fever and other symptoms consistent with a viral infection. If initial tests are inconclusive for specific viruses like Dengue or Zika, A92.9 might be used until more definitive results are available. , A patient with a known history of mosquito exposure reports general malaise, fever, and myalgia. Without clear evidence pointing towards a particular mosquito-borne disease, the physician might initially document the condition with A92.9, pending further diagnostic testing.
