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

What 90481 covers

90481 identifies administration of an additional component of a SARS-CoV-2 vaccine. It describes the administration service rather than the vaccine product. The code is distinct from 90480, which identifies administration of the initial or only SARS-CoV-2 vaccine component. Report 90481 for each additional component administered after the initial component, so the unit count follows the number of additional components. This code is specific to SARS-CoV-2 vaccine components, while general immunization administration codes describe vaccine administration in broader terms. Each reported unit corresponds to one additional component.

Medicare assigns status X, a statutory exclusion because this is not a physician service under the Medicare statute. The physician fee schedule does not pay the code. When covered, it is paid under another fee schedule or payment system. The initial or only component is reported with 90480; 90481 identifies each additional component.
