Common Language Description

The CPT® Code 91305 refers to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine, specifically designed to combat coronavirus disease (COVID-19). This vaccine utilizes a messenger RNA (mRNA) technology encapsulated in lipid nanoparticles (LNP), which is a method that allows the mRNA to be delivered effectively into human cells. The vaccine contains a dosage of 30 mcg in a 0.3 mL volume and is formulated without preservatives, ensuring a purer product for intramuscular administration. The mRNA included in the vaccine encodes the spike protein of the SARS-CoV-2 virus, which is critical for the virus's ability to infect human cells. Upon administration, the body's cells utilize this mRNA as a template to produce the spike protein, which is then recognized by the immune system as a foreign entity. This recognition triggers an immune response, leading to the production of antibodies that can neutralize the virus if the individual is exposed in the future. The vaccine's formulation includes tris-sucrose, which acts as a stabilizing agent, allowing the vaccine to be stored at standard refrigerator temperatures, thus facilitating easier distribution and storage. It is important to note that while this code reports the supply of the vaccine, the actual administration of the vaccine is billed separately using the appropriate administration code, depending on the specific dose given. This vaccine is part of a two-dose series, with a third booster dose available for populations recommended by the Centers for Disease Control and Prevention (CDC).
