Other babesiosis

This code represents a parasitic infection caused by Babesia species, excluding Babesia microti. It manifests as a malaria-like illness, often characterized by fever, chills, sweats, myalgia, and fatigue, and can lead to hemolytic anemia. The severity ranges from asymptomatic to life-threatening, particularly in immunocompromised individuals or those who have undergone splenectomy.

Assign this code when documentation confirms a diagnosis of babesiosis due to any Babesia species other than Babesia microti. This includes infections caused by Babesia divergens, Babesia duncani, or other unspecified Babesia species. Supporting documentation should include laboratory confirmation (e.g., blood smear, PCR) identifying the Babesia species or clearly stating "other babesiosis."

• Do not use this code for babesiosis caused by Babesia microti; a more specific code exists for that etiology.
• Ensure the medical record clearly distinguishes the Babesia species to avoid miscoding.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated complications.
