Chikungunya virus disease
ICD-10 A92.3 is a billable code used to indicate a diagnosis of chikungunya virus disease.
Chikungunya virus disease is an arthropod-borne viral infection caused by the chikungunya virus, primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. The disease is characterized by an abrupt onset of fever, severe joint pain, and rash. The fever typically lasts for a few days, but the joint pain can persist for weeks to months, leading to significant morbidity. Other symptoms may include headache, muscle pain, fatigue, and nausea. While chikungunya is rarely fatal, it can lead to chronic arthralgia in some patients, which may require long-term management. The disease is endemic in many tropical and subtropical regions, and outbreaks have been reported in Africa, Asia, Europe, and the Americas. A travel history to endemic areas is crucial for diagnosis, as it helps differentiate chikungunya from other febrile illnesses, such as dengue fever and Zika virus infection. Laboratory confirmation can be achieved through serological tests or PCR, which detect the virus or antibodies in the patient's blood.
Detailed travel history, symptom onset, and laboratory results.
Patients presenting with fever and joint pain after travel to endemic areas.
Ensure laboratory results are included to support diagnosis.
Comprehensive patient history, including travel and symptom duration.
Patients with febrile illness and joint pain without clear diagnosis.
Consider referral to specialists for chronic symptoms.
Used when serological confirmation of chikungunya is required.
Document the reason for testing and symptoms.
Infectious disease specialists may order this test more frequently.
Common symptoms include fever, severe joint pain, rash, headache, muscle pain, and fatigue. Joint pain can persist for weeks to months.
Diagnosis is based on clinical symptoms, travel history to endemic areas, and laboratory tests such as serology or PCR.
