Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 90473 covers

90473 reports the administration service for the first vaccine delivered by mouth or into the nose during the encounter. Examples include an oral rotavirus vaccine or an intranasal influenza vaccine. The vaccine product is coded separately. Nursing staff commonly administer these vaccines in a physician office or clinic, with the service reported by the practice responsible for the administration.

Select this code by route and order: it is for the first oral or intranasal vaccine, not an injectable vaccine or a count of vaccine components. Use 90474 for each additional oral or intranasal vaccine given at the same encounter. Documentation should identify the vaccine administered, its route, and the administration performed. CMS assigns physician work, practice-expense, and malpractice values to this service in the physician fee schedule; the vaccine product is a separate item from the administration service.
