Medicare physician requirements

We have a second year resident that needs to take a leave of absence due to a family emergency. He would like to be able to see patients and bill for his services during his leave of absence.
Since he is not yet board eligible we know he would not be able to see commercial health plan members. We are wondering if Medicare/CMS would allow him to bill for traditional members?
Do you know of any scenarios this could happen?

Thank you,

re: Medicare physician requirements

Where I am from residents can not bill Medicare at all. Only the supervising teaching physician can bill for services provided by the resident as long as he physically sees and evalutes the patient and reviews the residents documentation and makes any corrections to the notes. I was not aware that a resident can bill anywhere, but I could be wrong.
