B600 - Babesiosis - a tick-borne infection that affects red blood cells

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Babesiosis is an infection caused by tiny parasites called Babesia that are transmitted through tick bites, primarily from deer ticks (the same ticks that carry Lyme disease). These parasites invade and destroy red blood cells, which can cause symptoms similar to malaria including fever, chills, fatigue, body aches, and sometimes anemia. The infection is most commonly found in the northeastern and upper midwestern United States. Most people with healthy immune systems recover completely with proper treatment, but the infection can be more serious in people with weakened immune systems, the elderly, or those without a spleen. This diagnostic code indicates that babesiosis has been identified through laboratory testing or clinical examination.

Additional Information

Treatment typically involves antibiotics such as atovaquone plus azithromycin or clindamycin plus quinine. Prevention focuses on avoiding tick bites through protective clothing, repellents, and prompt tick removal. Co-infection with Lyme disease is possible since both are transmitted by the same tick species.
