Not sure Gen Res is the right board for this -- trainees aren't going to be the billing physicians of record so most who read this won't be on here. I also am not sure what you are trying to say here -- Medicare is one form of payment many physicians bill for. It neither reflects those physicians entire billings nor does it reflect the actual salaries they are paid. Its essentially just a portion of accounts receivable of the employer entity. It will perhaps tell you which physicians do a lot of their work for Medicare patients (which will be most) but I don't think you can draw many useful conclusions from these figures. Please expand on what you are trying to say/allege.
