CPT® Code 90674

Influenza virus vaccine, quadrivalent (ccIIV4), derived from cell cultures, subunit, preservative and antibiotic free, 0.5 mL dosage, for intramuscular use

The CPT® Code 90674 refers to a specific formulation of the influenza virus vaccine known as the quadrivalent cell culture-derived inactivated influenza vaccine (ccIIV4). This vaccine is designed to provide active, long-term immunity against influenza by stimulating the recipient's immune system to produce antibodies. Unlike immune globulins, which offer short-term, passive immunity, vaccines like this one expose the immune system to altered versions of the influenza virus, prompting it to recognize and combat the virus upon future exposure. The unique aspect of this vaccine is that it is derived from cell cultures, which allows for production in a sterile and controlled environment, eliminating the need for embryonated eggs, preservatives, and antibiotics. This makes the vaccine non-allergenic and suitable for individuals who may have sensitivities to these components. The quadrivalent formulation includes two strains of influenza type A and two strains of influenza type B, providing broader protection against circulating influenza viruses. The specific dosage for this vaccine is 0.5 mL, and it is intended for intramuscular administration. The code 90674 is used solely to report the vaccine product itself, ensuring accurate documentation and billing for the immunization provided.
