Dengue fever, unspecified
ICD-10 A77.9 is a billable code used to indicate a diagnosis of dengue fever, unspecified.
Dengue fever is a viral illness transmitted primarily by Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. It is characterized by high fever, severe headache, retro-orbital pain, myalgia, arthralgia, and rash. The disease can progress to severe dengue, which may lead to hemorrhagic manifestations and shock. The unspecified designation indicates that the specific type or severity of dengue fever has not been documented. Dengue fever is endemic in tropical and subtropical regions, and its incidence has increased dramatically in recent decades, making it a significant public health concern. The clinical presentation can vary widely, and laboratory confirmation is essential for diagnosis. Travel-related infections are common, as individuals visiting endemic areas may contract the virus. Vector control measures and public health interventions are crucial in managing outbreaks and preventing transmission.
Detailed travel history, clinical symptoms, and laboratory results.
Patients presenting with fever and travel history to endemic areas.
Consideration of differential diagnoses such as chikungunya and Zika virus.
Comprehensive assessment of symptoms and potential complications.
Patients with acute febrile illness and recent travel.
Timely identification of severe dengue to initiate appropriate management.
Used to confirm diagnosis in suspected cases.
Document the reason for testing and clinical findings.
Infectious disease specialists may require additional serological tests.
A77.9 is used for unspecified dengue fever, while A77.0 is specifically for dengue fever with hemorrhagic manifestations, which requires different clinical documentation.
