CPT® Code 87802

The CPT® Code 87802 refers to the detection of infectious agent antigens through an immunoassay method, specifically targeting the Streptococcus group B (Strep B). This group of bacteria is known to cause severe infections, particularly in vulnerable populations such as newborns, pregnant women, the elderly, and individuals with compromised immune systems. In newborns, Strep B can lead to life-threatening conditions including pneumonia, meningitis, and sepsis. In adults, especially pregnant women, it can result in serious infections like urinary tract infections, skin infections, and pneumonia. The primary purpose of this test is to screen for the presence of Strep B during pregnancy, allowing for timely intervention to prevent potential complications. The testing process involves obtaining a specimen through a swab of the cervix and lower third of the vagina, followed by the use of a rapid test kit designed to detect Strep B antigens. The procedure is dependent on the specific test kit used, but generally involves a series of reagent additions and observations to determine the presence of the antigen, ultimately providing critical information for the management of both maternal and neonatal health.
