Dengue fever
ICD-10 A91 is a billable code used to indicate a diagnosis of dengue fever.
Dengue fever is a mosquito-borne viral infection caused by the dengue virus, which is transmitted primarily by Aedes aegypti mosquitoes. The disease is characterized by high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. Dengue fever can progress to more severe forms, such as dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), which can be life-threatening. The clinical presentation typically occurs 4 to 10 days after being bitten by an infected mosquito. Diagnosis is primarily based on clinical symptoms and confirmed through serological tests or PCR. Travel history is crucial, as dengue is endemic in tropical and subtropical regions, and outbreaks can occur in urban areas. Patients with a history of travel to endemic areas should be evaluated for dengue, especially during outbreaks. Management is supportive, focusing on hydration and pain relief, as there is no specific antiviral treatment for dengue. Monitoring for complications is essential, particularly in patients with severe manifestations.
Detailed clinical notes on symptoms, travel history, and laboratory results.
Patients presenting with fever and travel history to endemic areas.
Ensure all relevant symptoms and potential complications are documented.
Immediate assessment notes, including vital signs and initial lab results.
Patients with acute febrile illness after travel.
Rapid identification of severe cases to ensure appropriate coding and management.
Used to confirm diagnosis in patients with suspected dengue fever.
Document the reason for testing and clinical findings.
Infectious disease specialists should ensure comprehensive documentation of symptoms.
Dengue fever is a milder form of the disease characterized by fever and mild bleeding, while dengue hemorrhagic fever is a severe form that can lead to bleeding, organ impairment, and shock.
