Ehrlichiosis chaffeensis [E. chaffeensis]
ICD-10 A77.41 is a billable code used to indicate a diagnosis of ehrlichiosis chaffeensis [e. chaffeensis].
Ehrlichiosis chaffeensis is a tick-borne infectious disease caused by the bacterium Ehrlichia chaffeensis, primarily transmitted through the bite of infected Amblyomma americanum (Lone Star tick). This disease is characterized by a range of clinical manifestations, including fever, chills, headache, myalgia, and sometimes a rash. The incubation period typically ranges from 7 to 14 days post-exposure. Severe cases may lead to complications such as respiratory failure, renal failure, and even death if not treated promptly. Diagnosis is often made through serological testing or PCR, and treatment usually involves the use of doxycycline. Given its vector-borne nature, Ehrlichiosis is more prevalent in certain geographic regions, particularly in the southeastern and south-central United States, and is often associated with outdoor activities in tick-infested areas. Awareness of this disease is crucial for healthcare providers, especially in endemic regions, to ensure timely diagnosis and management.
