CPT® Code 90637

The CPT® Code 90637 refers to a specific type of influenza virus vaccine known as the quadrivalent influenza vaccine, which is designed to protect against influenza diseases caused by both influenza A subtype viruses and type B viruses that are included in the vaccine formulation. This vaccine utilizes messenger RNA (mRNA) technology, which represents a significant advancement in vaccine development. Unlike traditional vaccines that may use inactivated or weakened forms of the virus, mRNA vaccines employ lab-created mRNA that encodes a viral protein or a segment of it. This innovative approach stimulates the body’s immune system to recognize and respond to the influenza virus effectively. One of the key advantages of mRNA vaccines is their flexibility in manufacturing, allowing for rapid adaptation to match the constantly evolving strains of influenza that circulate each flu season. This capability enhances the likelihood of providing effective protection against the most prevalent strains during a given flu season or pandemic. The specific dosage for this vaccine is 30 mcg per 0.5 mL, and it is intended for intramuscular use. It is important to note that while the vaccine itself is reported under code 90637, the actual administration of the vaccine via intramuscular injection is reported separately, ensuring accurate billing and documentation for healthcare providers.
