I pull my hair out when I have to deal with the a few times a year. I can't imagine dealing with them everyday.
It seems to be getting worse. My insurance program is nominally a good one. However, it is so complex that it is impossible to know what the charges will be on any given invoice. When I get the report after the fact, it seems completely arbitrary. Never mind that I have different tiers where I am responsible for all/some/none of the invoice. It is maddening.
The net result is that the Doctors don't know what to charge when I walk in. They have to submit it to insurance and wait to see what my shared cost is supposed to be. Which means they are always chasing payments months after the service and that is on an amount that has been drastically cut down.
Maybe I am naive but if I were a Doctor, I would prefer to work with one big payer that I could understand and trust to be consistent.
Incidentally, I believe a big chunk of remaining resistance would disappear overnight if the proposal included a bump in the reimbursement levels. I know this would compound the question of paying for it. But i think it is an inevitable requirement to get enough Doctors into the system to cover the load.
