Tetanus toxoid adsorbed, for intramuscular use, is a vaccine designed to provide long-lasting immunity against the toxin produced by the bacterium Clostridium tetani. This vaccine works by stimulating the body's immune system to produce antibodies that specifically target and neutralize the tetanus toxin. The process of creating the toxoid involves culturing the bacteria in a controlled liquid medium, followed by purification and inactivation of the toxin, rendering it non-infectious while still capable of eliciting an immune response. As a result, the vaccine is classified as a toxoid rather than a live vaccine. It is important to note that immunity from the tetanus toxoid can diminish over time, which is why booster doses are recommended to maintain adequate protection. The administration of this vaccine is performed via intramuscular injection, ensuring that it is delivered effectively into the muscle tissue. This code, CPT® 90703, specifically reports the use of tetanus toxoid alone, distinguishing it from other related vaccines, such as diphtheria and tetanus toxoids (DT) adsorbed, which is reported under CPT® code 90702 for patients younger than 7 years. Both codes serve to identify the specific toxoid product utilized in immunization efforts.
