Common Language Description

The CPT® Code 90466 refers to the administration of immunizations for patients who are younger than 8 years of age. This code encompasses various methods of vaccine delivery, including percutaneous, intradermal, subcutaneous, or intramuscular injections. It is specifically applicable when the physician provides counseling to the patient or their family during the immunization process. The code is utilized for each additional injection administered on the same day, whether the vaccine is a single entity or a combination of vaccines/toxoids. It is important to note that this code is listed separately in addition to the code for the primary procedure, ensuring that healthcare providers can accurately bill for multiple immunizations given during a single visit.
