Ehrlichiosis, unspecified
ICD-10 A77.40 is a billable code used to indicate a diagnosis of ehrlichiosis, unspecified.
Ehrlichiosis is a tick-borne infectious disease caused by bacteria of the genus Ehrlichia, which are obligate intracellular pathogens. The disease is primarily transmitted through the bite of infected ticks, particularly the Lone Star tick (Amblyomma americanum) and the black-legged tick (Ixodes scapularis). Symptoms typically manifest 1-2 weeks post-exposure and may include fever, chills, headache, muscle aches, and fatigue. In severe cases, patients may experience complications such as respiratory distress, renal failure, or coagulopathy. Diagnosis is often made through clinical evaluation and serological testing, although PCR testing can also be utilized for confirmation. The unspecified designation in this code indicates that the specific type of Ehrlichia causing the infection has not been identified, which can complicate treatment and management. Prompt recognition and treatment with appropriate antibiotics, such as doxycycline, are crucial to prevent severe outcomes. Given the vector-borne nature of this disease, awareness of travel-related risks, especially in endemic areas, is essential for prevention and early intervention.
Detailed patient history including travel and exposure, laboratory results, and treatment plans.
Patients presenting with fever and recent tick exposure, or those with atypical febrile illnesses.
Consideration of co-infections with Lyme disease or other tick-borne illnesses.
Thorough documentation of symptoms, travel history, and any tick exposure.
Patients with flu-like symptoms during tick season or after outdoor activities in endemic areas.
Awareness of local epidemiology and patient education on tick prevention.
Used when confirming a diagnosis of Ehrlichiosis through PCR testing.
Documentation of clinical suspicion and test results.
Infectious disease specialists may order this test more frequently.
Common symptoms include fever, chills, headache, muscle aches, and fatigue. Severe cases may lead to complications such as respiratory distress or renal failure.
Diagnosis is typically made through clinical evaluation, serological testing, or PCR testing to confirm the presence of Ehrlichia.
The primary treatment for Ehrlichiosis is doxycycline, which is effective in most cases when administered early.
