Babesiosis due to Babesia divergens

This code identifies babesiosis specifically caused by the parasite Babesia divergens. This is a tick-borne parasitic infection that invades and destroys red blood cells, leading to hemolytic anemia and fever, and can be severe, particularly in immunocompromised individuals or those who have undergone splenectomy.

Assign this code when medical record documentation explicitly states a diagnosis of babesiosis and specifies Babesia divergens as the causative agent, typically confirmed by laboratory testing such as blood smear microscopy or PCR. This code is appropriate for both acute and chronic presentations of Babesia divergens infection.

• Ensure the documentation clearly specifies Babesia divergens as the etiologic agent; do not assume based on geographic location alone.
• Distinguish from other specified or unspecified babesiosis codes (e.g., B60.00, B60.01, B60.02, B60.09).
• Code any associated manifestations, such as hemolytic anemia (D59.30-D59.39), as secondary diagnoses.
