CPT® Code 90585

The Bacillus Calmette-Guerin vaccine (BCG) is a live vaccine specifically designed to provide active immunity against tuberculosis, a serious infectious disease caused by the bacterium Mycobacterium tuberculosis. Unlike immune globulins, which offer short-term, passive immunity, vaccines like BCG stimulate the recipient's immune system to produce its own antibodies, leading to long-term protection. This process involves exposing the immune system to a weakened form of the pathogen, allowing the body to "remember" how to respond effectively upon future exposure to the actual disease-causing organism. The BCG vaccine is derived from a live, attenuated strain of Mycobacterium bovis, which is a type of bovine tuberculosis. This strain has been cultured in a controlled environment for an extended period, rendering it nonvirulent to humans while still capable of eliciting an immune response. In addition to its primary use in preventing tuberculosis, the BCG vaccine has also been utilized in the treatment of bladder cancer, although the exact mechanisms by which it exerts its effects in oncology remain partially understood. The CPT® Code 90585 specifically refers to the administration of the live BCG vaccine for percutaneous use, while a different code, 90586, is designated for instances where the vaccine is instilled directly into the bladder via catheter for cancer treatment. It is important to note that these codes are strictly for reporting the vaccine product itself.
