CPT® Code 86880

The CPT® Code 86880 refers to the Antihuman globulin test, commonly known as the direct Coombs test, which is utilized in laboratory settings to measure the presence of antihuman globulin. This test is particularly significant in the diagnosis and management of hemolytic anemia, a condition characterized by the premature destruction of red blood cells due to antibodies that bind to these cells. The direct Coombs test is performed when there is a positive result from an antibody screening test for anti-globulins or when a patient exhibits symptoms indicative of hemolytic anemia. Symptoms may include pale skin, fatigue, weakness, and dizziness, which are manifestations of the underlying condition. Hemolytic anemia can arise from various causes, including autoimmune diseases such as systemic lupus erythematosus, malignant conditions like lymphoma or chronic lymphocytic leukemia, infections such as mycoplasma pneumonia and infectious mononucleosis, and adverse reactions to medications, including penicillin. Additionally, transfusion reactions can lead to hemolytic anemia. In newborns, exposure to maternal antibodies during pregnancy can result in hemolytic disease of the newborn. The test involves obtaining a blood sample through venipuncture, which is a separately reportable procedure, and the serum is then analyzed using hemagglutination techniques to determine the presence of antihuman globulin.
