Code Description

ICD-10 B60.03 is a billable code used to indicate a diagnosis of babesiosis due to babesia divergens.

Key Diagnostic Point:

Babesiosis is a protozoal infection caused by the genus Babesia, with Babesia divergens being one of the species responsible for human infections. This disease is primarily transmitted through the bite of infected Ixodes ticks, commonly known as deer ticks. Babesia divergens is particularly prevalent in Europe and is associated with severe disease in individuals with compromised immune systems, such as those with splenectomy or other underlying health conditions. Clinical manifestations of babesiosis can range from asymptomatic to severe illness, characterized by symptoms such as fever, chills, sweats, headache, myalgia, and fatigue. Severe cases may lead to hemolytic anemia, thrombocytopenia, and multi-organ failure. Diagnosis is typically confirmed through blood smear examination, PCR testing, or serological assays. Treatment usually involves antimalarial medications such as atovaquone combined with azithromycin or clindamycin and quinine for more severe cases. Prompt diagnosis and treatment are crucial to prevent complications, especially in high-risk populations.

  • Need for accurate documentation of tick exposure
  • Variability in clinical presentation
  • Potential for co-infection with Lyme disease

Audit Risk Factors

  • Inadequate documentation of tick exposure
  • Failure to document laboratory confirmation
  • Misdiagnosis due to overlapping symptoms with other infections
  • Inconsistent coding of co-infections
