ICD-10 Code B60.0 – Babesiosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B60.0 – Babesiosis
What it is
B60.0 identifies babesiosis, a parasitic infection caused by Babesia species. Use it when documentation states babesiosis or a Babesia infection without a more specific code.
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 B60.0 when the provider documents babesiosis as the confirmed diagnosis, including cases noted by species if no more specific ICD-10-CM code is available. It also fits encounters for ongoing management after diagnosis is established. If the record only says suspected tick-borne illness, check documentation before coding.
Do not use for
Do not use B60.0 for Lyme disease, malaria, or other unrelated parasitic infections. If the note does not clearly identify babesiosis, check documentation.
Coding tip
Code the confirmed Babesia infection exactly as documented and verify any coexisting hemolytic anemia or splenic complications separately.
