Collections are all monies that are brought in - all fees, regardless of where they come from. ASC, PT, imaging, etc. Collections is the gross, it does not account for overhead, etc. So if you are a hospital employeed physician, you will only get x amount of salary and the hospital will pocket all the other monies outside of your salary and any overhead they have. So in this scenario, if they collect 1 million dollars from insurance, ASC, therapy, imaging, and pay you 300k, and say their overhead is 200k, then they will make 500k. You still only make 300k. If you are a private practice physician, you collect 1 million from everything, and take out any overhead - paying your rent, your staff, your supplies, etc. etc., and then whatever is left is divided by the partners/employees. So if you and Dr. x are partners, you collect 1 million from everything (procedures, imaging, therapy, etc etc), and say you have have 400k in expenses, then you divide the other 600k between the two of you.
