What This Code Means
B60.03 is the ICD-10-CM diagnosis code for babesiosis due to babesia divergens. A parasitic blood infection caused by Babesia divergens, a type of parasite that primarily affects people with weakened immune systems or those who have had their spleen removed. B60.03 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering protozoal diseases (b50-b64).
B60.03 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Babesia divergens is more common in Europe and typically affects asplenic or immunocompromised patients.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B60.03 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Babesia divergens is more common in Europe and typically affects asplenic or immunocompromised patients
- •Document any splenectomy or immunocompromised status to support the diagnosis
