CPT® Code 90718

Deleted

The CPT® Code 90718 refers to the administration of tetanus and diphtheria toxoids (Td) that are adsorbed, specifically designed for individuals aged 7 years and older. Toxoids are inactivated toxins produced by bacteria, which are used in vaccines to stimulate the immune system. By introducing these altered forms of toxins into the body, the immune system is prompted to produce antibodies that can effectively neutralize the specific toxins if encountered in the future. This process results in long-lasting immunity, as the body retains a memory of how to produce these antibodies upon subsequent exposures to the same pathogens. The Td vaccine is administered via intramuscular injection, making it a straightforward and effective method for immunization. It is important to note that since toxoids are not live vaccines, booster doses are necessary to maintain immunity over time, as the protective effects can diminish. The Td vaccine is particularly relevant for adults and older children, ensuring they are protected against the serious diseases caused by tetanus and diphtheria. Additionally, related codes such as 90715 and 90714 pertain to other formulations of tetanus and diphtheria vaccines, including combinations with acellular pertussis, highlighting the variety of immunization options available to healthcare providers.
