CPT codes are standardized medical billing codes created and maintained by the American Medical Association (AMA). These codes allow healthcare providers, hospitals, and insurers to communicate clearly about the services delivered to patients.

Unlike vaccine product codes, 90471 CPT code specifically describes the administration of one injectable vaccine when counseling is provided by a physician or qualified healthcare professional.
