ICD-10 Code B60.00 – Babesiosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B60.00 – Babesiosis, unspecified
What it is
B60.00 identifies babesiosis when the organism or species is not further specified. Use it for a parasitic infection transmitted by ticks or blood exposure when documentation confirms babesiosis but does not name a specific type.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include febrile illness, chills, fatigue, headache, and hemolytic anemia. Severe cases may show jaundice, dark urine, or complications in asplenic or immunocompromised patients.
When to use this code
Use B60.00 when the record states babesiosis without identifying the species or subtype. It also fits when the clinician documents suspected or confirmed babesiosis and the note lacks enough detail for a more specific code. Check documentation if the infection is linked to a different specified organism.
Do not use for
Do not use this code for malaria, Lyme disease, or other tick-borne infections that are documented separately. If the record specifies a particular Babesia species or another more precise diagnosis, code that instead.
Coding tip
Assign the most specific babesiosis code available; if the organism is not named, B60.00 is appropriate.
