Thread: Which Modifier

    Default Which Modifier

    AAPC: Back to School
    We have a patient who was seen in the hospital by one of our Hospitalists and then on the same day one of our Cardiologist saw the patient. Both providers billed the same dx. Medicare has denied our Cardiologist claim because both of our providers bill under the same Group Number. After placing a call to Medicare and explaining that each of our providers have different taxonomies and NPIs we were instructed to use an appropriate modifier to show a repeat visit. I am confused as to which modifier they are referencing. Please advise and Thanks for any help in this matter.

    I usually add mod -AF for my cardio Dr. This modifier shows that he is a specialist.
