CPT® Code 90581

The CPT® Code 90581 refers to the anthrax vaccine, which can be administered either subcutaneously or intramuscularly. Vaccines, unlike immune globulins that offer short-term, passive immunity, are designed to provide active, long-term immunity. This is achieved by introducing altered versions of specific pathogens, such as viruses or bacteria, into the recipient's immune system. This exposure prompts the immune system to produce its own antibodies, enabling the body to recognize and combat the actual pathogen in future encounters. Anthrax, the disease targeted by this vaccine, is caused by the bacterium Bacillus anthracis and its spores. The inhalation of anthrax spores can lead to a fatal form of the disease, resulting in pneumonia, while the cutaneous form, which manifests through skin contact, is more prevalent among humans. It is important to note that this code specifically reports the anthrax vaccine product used, without including any additional services or procedures associated with its administration.
