Well he's free to set his rate no matter what the insurance company/comanies reimburse. But one thing that raising their fee does it that when number crunchers look to see what the average rate is in order to determine the amount the insurance companies will approve, they use the data they have which is the amount charged...so.. if the billed amount increases (overall--from various providers of the same service) then the amount the insurance company will allow, or will consider reasonable or customary, also may increase. So the T might receive a higher reimbursement. Surgeons and other providers do that too.

It's good for those who pay a set copay because that doesn't change. For those that pay a percentage of what their insurance allows, then their share goes up too.

It is a convoluted little game, isn't it?!
