CPT® Code 86717

The CPT® Code 86717 refers to a laboratory test specifically designed to measure antibodies against Leishmania, a parasitic organism. Leishmania is primarily found in tropical and subtropical regions, as well as Southern Europe, and is transmitted to humans through the bite of infected sand flies. The infection can manifest in two primary forms: cutaneous and visceral. The cutaneous form is marked by the development of skin sores or ulcers, which may become scabbed or crusted, and is often associated with swollen lymph nodes. In contrast, the visceral form of the disease occurs when the parasite invades internal organs such as the liver, spleen, and bone marrow. Symptoms of visceral leishmaniasis can vary widely; some individuals may remain asymptomatic, while others may experience significant clinical manifestations including fever, weight loss, enlargement of the spleen and liver, anemia, leukopenia, or thrombocytopenia. The presence of a positive IgG antibody titer in the test results indicates either a current or past infection with Leishmania. To perform this test, a blood sample is collected from the patient through a procedure known as venipuncture, which is reported separately. The serum obtained from the blood sample is then analyzed using a semi-quantitative immunoassay to determine the level of antibodies present.
