ICD-10 Code B60.03 – Babesiosis due to Babesia divergens (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B60.03 – Babesiosis due to Babesia divergens
What it is
B60.03 identifies babesiosis caused by Babesia divergens, a parasitic infection transmitted by ticks or blood exposure. It is used when documentation names this specific organism.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include fever, chills, fatigue, hemolytic anemia, and sometimes jaundice or dark urine.
When to use this code
Use B60.03 when the record clearly states babesiosis due to Babesia divergens, or confirms that exact species. Code it from provider documentation, not from suspicion alone.
If the chart only says babesiosis without species detail, choose the unspecified babesiosis code instead. Check documentation when the organism is not identified.
Do not use for
Do not use this code for babesiosis caused by another Babesia species or for a nonspecific babesiosis diagnosis. Also avoid it when babesiosis is only ruled out.
Coding tip
Verify the organism name in the assessment or lab report before assigning B60.03.
