Thread: AS modifier

  1. #1

    Default AS modifier

    AAPC: Back to School
    Does anyone know where I can find a list that is CPT code specific for the AS modifer? Medicare is denying CPT codes 58263, 57260 and 57288 stating that AS modifier is not allowed with this code.

    Under "Type of information" click payment indicators
    enter CPT code
    On drop down key...select "all modifiers"
    Assist Surgery column indicates payment status

    0-documentation required to support medical necessity
    1-Assist may not be paid
    2-Assist can be paid
    9-concept does not apply

    Thanks for the info. Do you know if there is a list more specific as to the type of provider that is the assistant surgeon? In our case, the AS is a physician assistant.
