CPT® Code 90586

The Bacillus Calmette-Guerin vaccine (BCG) is a live vaccine specifically designed for intravesical use in the treatment of bladder cancer. Unlike immune globulins, which provide short-term, passive immunity, vaccines like BCG offer active, long-term immunity. This is achieved by exposing the recipient's immune system to altered versions of specific bacteria, prompting the immune system to produce its own antibodies against the invading microorganisms. The BCG vaccine is derived from a live, weakened strain of Mycobacterium bovis, which is the bacterium responsible for bovine tuberculosis. This strain is attenuated through a prolonged culturing process in a controlled artificial medium, rendering it nonvirulent to humans. While the primary use of the BCG vaccine is for the prevention of tuberculosis, it has also been found effective in treating bladder cancer, although the precise mechanisms by which it combats cancer are not fully understood. It is important to note that CPT® Code 90585 is designated for the live BCG vaccine used for percutaneous injection against tuberculosis, whereas CPT® Code 90586 is specifically used when the vaccine is instilled through a catheter into the bladder for the treatment of bladder cancer. Both codes serve to report the product (vaccine) utilized in these procedures.
