CPT® Code 90381

The CPT® Code 90381 refers to a specific monoclonal antibody vaccine designed to provide protection against respiratory syncytial virus (RSV). This vaccine is administered in a 1 mL dosage via intramuscular injection. The primary function of this vaccine is to stimulate the recipient's immune system, enabling it to produce antibodies that can effectively combat RSV upon exposure. RSV is a highly contagious virus that is known to cause acute respiratory infections, particularly affecting infants, young children, and vulnerable populations such as the elderly or those with compromised immune systems. The virus typically circulates during the fall and winter months, making seasonal vaccination crucial for at-risk groups. The monoclonal antibody contained in this vaccine is engineered to mimic the natural immune response, providing a proactive defense against RSV. This is especially important for infants and neonates during their first RSV season, as they are at a heightened risk for severe illness, including pneumonia and potential hospitalization. The administration of this vaccine is a preventive measure aimed at reducing the incidence of RSV-related complications in young children and infants who are particularly susceptible to the virus.
