Thread: Unilateral Screening Mammo

    Exclamation Unilateral Screening Mammo

    AAPC: Back to School
    I don't know if this is the correct forum to post this question or not.....

    If a patient presents to the clinic for a screening mammo that is only performed unilateral, how do you report this?

    Do you report code 77057 with modifier 52?


    Do you report code 77056?

    My understanding has always been that 77057 is for screening mammos (as indicated in the description of the code) and 77055/77056 are for diagnostic mammos (but the description does not state this).

    Any clarification is appreciated. Thanks in advance.
