Babesiosis due to Babesia duncani

This code identifies an infection caused by the parasitic protozoan Babesia duncani, a specific species of Babesia. Babesiosis is a tick-borne illness that infects red blood cells, leading to symptoms such as fever, chills, sweats, fatigue, and hemolytic anemia.

Assign this code when medical record documentation explicitly states a diagnosis of babesiosis confirmed to be caused by Babesia duncani. This typically follows laboratory confirmation through blood smear microscopy, PCR testing, or serology identifying the specific Babesia duncani species.

• Ensure documentation specifies Babesia duncani as the causative agent; otherwise, use a more general babesiosis code.
• Do not confuse with malaria, which presents similarly but is caused by Plasmodium parasites.
• Code any associated complications, such as hemolytic anemia, separately.
