Code Description

ICD-10 B60.01 is a billable code used to indicate a diagnosis of babesiosis due to babesia microti.

Key Diagnostic Point:

Babesiosis is a malaria-like parasitic disease caused by protozoa of the genus Babesia, with Babesia microti being the most common species affecting humans in the United States. The disease is primarily transmitted through the bite of infected Ixodes scapularis ticks, commonly known as deer ticks. Clinical manifestations of babesiosis can range from asymptomatic to severe illness, particularly in immunocompromised individuals or those without a spleen. Symptoms typically include fever, chills, sweats, headache, body aches, loss of appetite, nausea, and fatigue. Laboratory findings may reveal hemolytic anemia, thrombocytopenia, and elevated liver enzymes. Diagnosis is confirmed through blood smear examination or serological tests. Treatment usually involves the use of antimalarial medications such as atovaquone combined with azithromycin or clindamycin combined with quinine. Prompt diagnosis and treatment are crucial to prevent complications such as respiratory failure, renal failure, and even death in severe cases.
