CPT® Code 86001

The CPT® Code 86001 refers to the quantitative or semiquantitative testing of allergen-specific IgG immunoglobulins in a blood sample. This procedure involves obtaining a blood sample from the patient to analyze the presence of IgG antibodies that are specific to various allergens. These allergens may include a range of substances such as foods or venoms that can trigger allergic reactions. Unlike skin tests, which are conducted in vivo, this blood test is categorized as an in vitro test, meaning it is performed outside the body in a laboratory setting. The results of this test can help identify sensitivities to multiple allergens, and it is often utilized in the context of food allergies or insect sting allergies. When testing for sensitivities to several food items, the test may be referred to as a food allergy panel, while testing for multiple venoms may be termed a stinging insect allergy profile. It is important to note that the code 86001 is reported for each individual antigen tested, allowing for detailed tracking and analysis of specific allergen sensitivities.
