CPT® Code 90687

The CPT® Code 90687 refers to a specific type of influenza virus vaccine known as the quadrivalent influenza vaccine (IIV4). This vaccine is designed to provide protection against four different strains of the influenza virus, specifically two strains of influenza type A and two strains of influenza type B. The term "quadrivalent" indicates that the vaccine targets multiple strains, enhancing its effectiveness in preventing influenza infections during the flu season. The vaccine is classified as a split virus vaccine, meaning that the virus particles have been chemically disrupted to create a form that can stimulate an immune response without causing disease. This process involves the use of embryonated chicken eggs, where the virus is cultivated, harvested, and then inactivated using formaldehyde. The resulting vaccine is administered in a dosage of 0.25 mL via intramuscular injection. It is important to note that while vaccines like this one provide active, long-term immunity by prompting the immune system to produce antibodies, they differ from immune globulins, which offer short-term, passive immunity. When coding for this vaccine, it is essential to report the specific dosage administered, with code 90687 designated for the 0.25 mL dosage. Additionally, the intramuscular injection itself must be reported separately, as the CPT code only accounts for the vaccine product used.
