CPT® Code 90692

Deleted

The CPT® Code 90692 refers to the Typhoid vaccine that is heat- and phenol-inactivated (H-P) and is intended for subcutaneous or intradermal use. Vaccines, such as this one, are designed to provide active, long-term immunity by stimulating the recipient's immune system to recognize and combat specific pathogens. Unlike immune globulins, which offer short-term, passive immunity, vaccines work by introducing altered forms of viruses or bacteria, prompting the immune system to produce its own antibodies. This process enables the body to 'remember' how to generate these antibodies upon subsequent exposure to the same antigens. Typhoid fever, caused by the bacterium Salmonella typhi, is characterized by symptoms such as high fever, rash, and diarrhea, and is transmitted through contaminated food, water, and milk. The use of this vaccine is crucial in preventing typhoid infection, particularly in areas where the disease is endemic. The CPT® coding system provides various codes for different types of typhoid vaccines, including the oral vaccine (CPT® Code 90690), the Vi capsular polysaccharide vaccine for intramuscular injection (CPT® Code 90691), and the acetone killed dried vaccine used by the military (CPT® Code 90693). Each code specifically identifies the type of vaccine administered, ensuring accurate reporting and tracking of immunization efforts.
