CPT® Code 90702

The CPT® Code 90702 refers to the administration of diphtheria and tetanus toxoids adsorbed (DT) specifically for individuals who are younger than 7 years of age. This vaccine is administered via intramuscular injection and is designed to provide long-lasting immunity against the diseases caused by the toxins produced by the bacteria responsible for diphtheria and tetanus. Toxoids are inactivated forms of the toxins that stimulate the immune system to produce antibodies, which are crucial for neutralizing the harmful effects of these toxins. The process of creating a toxoid involves culturing the bacteria in a controlled liquid medium, followed by purification and inactivation of the toxin produced. It is important to note that since toxoids are not live vaccines, the immunity they confer can diminish over time, necessitating booster doses to maintain adequate protection. The code 90702 specifically reports the use of the diphtheria and tetanus toxoids (DT) product administered to eligible patients, emphasizing its role in immunization for young children.
