CPT® Code 90476

The CPT® Code 90476 refers to the Adenovirus vaccine, specifically type 4, which is administered orally. Vaccines, unlike immune globulins that offer short-term, passive immunity, provide active and long-lasting immunity. This is achieved by introducing altered forms of specific viruses or bacteria into the recipient's body, prompting the immune system to generate its own antibodies against these pathogens. Once vaccinated, the body retains a memory of how to produce these antibodies, enabling a quicker and more effective response upon subsequent exposure to the same antigen. Adenoviruses are known to cause a range of respiratory illnesses, including the common cold, croup, bronchitis, and pneumonia. Additionally, they can lead to other health issues such as conjunctivitis, cystitis, and gastroenteritis, which vary based on the specific serotype and the site of infection. The codes for adenovirus vaccines, including 90476 for type 4 and 90477 for type 7, are utilized solely to report the vaccine product administered.
