Other specified spotted fevers
ICD-10 A77.8 is a billable code used to indicate a diagnosis of other specified spotted fevers.
A77.8 encompasses a variety of rickettsial diseases that are characterized by fever and rash, transmitted primarily through arthropod vectors such as ticks, fleas, and lice. These diseases include but are not limited to Rickettsia typhi (murine typhus), Rickettsia prowazekii (epidemic typhus), and other less common rickettsial infections. The clinical presentation often includes fever, headache, myalgia, and a characteristic rash that may vary in appearance depending on the specific pathogen. Diagnosis is typically made through clinical evaluation and serological testing, as well as consideration of the patient's travel history and exposure to potential vectors. Given the zoonotic nature of these infections, they are particularly relevant in endemic areas and among travelers to such regions. The management of spotted fevers generally involves the use of antibiotics, with doxycycline being the first-line treatment. Understanding the epidemiology and clinical manifestations of these diseases is crucial for timely diagnosis and treatment, especially in patients with a history of travel to endemic areas.
Detailed travel history, exposure risks, and laboratory results.
Patients presenting with fever and rash after travel to endemic areas.
Consideration of differential diagnoses and potential co-infections.
Comprehensive patient history and symptom documentation.
Patients with unexplained fever and rash, especially after travel.
Awareness of local epidemiology and potential exposure risks.
Used when a rickettsial infection is suspected based on clinical presentation.
Document the clinical rationale for testing and any relevant travel history.
Infectious disease specialists may require more detailed documentation.
Common symptoms include fever, headache, myalgia, and a rash that may vary in appearance depending on the specific rickettsial infection.
Diagnosis is typically made through clinical evaluation, serological testing, and consideration of the patient's travel history and exposure to vectors.
