About B60.0

B60.0 is the ICD-10-CM diagnosis code for babesiosis. It belongs to category B60 (other protozoal diseases, not elsewhere classified), block B50-B64 (protozoal diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within B60 (other protozoal diseases, not elsewhere classified), B60.0 is specifically for babesiosis. Related codes cover Acanthamebiasis (B60.1), Naegleriasis (B60.2) and other specified protozoal diseases (B60.8).

To report this condition, pick the subcode that matches the documentation: B60.00 (unspecified), B60.01 (due to Babesia microti), B60.02 (due to Babesia duncani), B60.03 (due to Babesia divergens) and B60.09 (babesiosis).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 088.82 (babesiosis).
