CPT® Code 90716

The CPT® Code 90716 refers to the Varicella virus vaccine, which is a live vaccine administered subcutaneously. 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 respond by producing its own antibodies. The immune system retains a memory of how to produce these antibodies, allowing for a quicker and more effective response upon subsequent exposures to the same pathogen. The Varicella virus vaccine specifically targets the varicella-zoster virus, which is responsible for chickenpox and shingles. The vaccine contains a live, attenuated version of the virus, meaning it has been weakened to the point where it can stimulate an immune response without causing the actual disease. This vaccination is crucial for preventing chickenpox, a highly contagious disease, and shingles, which can occur later in life as a reactivation of the varicella-zoster virus. The administration of this vaccine is essential for public health, as it helps to reduce the incidence of these diseases and their associated complications.
