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

What 90474 covers

This code represents administration of an additional vaccine given by mouth or intranasally during the same encounter. Examples of these routes include oral rotavirus vaccine and intranasal influenza vaccine. A physician, nurse, or other qualified clinical staff member may administer the vaccine in a physician office or clinic; the vaccine product itself is not the service represented by this code.

Report one unit for each additional oral or intranasal vaccine administered, not for each component of a combination vaccine or each dose in a series. The record should identify the vaccine, route, and administration, and show which vaccine administration service is primary. CMS classifies 90474 as an add-on code: report it only with a primary procedure, and its payment is within that procedure's global period. For a first or only oral/nasal vaccine, 90473 is the route-specific initial service; when routes are mixed, select the additional-administration code according to the route of each additional vaccine.
