When obamacare first passed my cardiologist at the time had three partners and a fairly big clinic. He told me they figured out they would have to increase their number of patients by a third to make the same amount of money. A few months later I started using the VA and about a month after that I got a letter that their office was closing and he went back to working for a hospital.
My own doc went to a concierge style limited practice, so I pay $100 per month in addition to my premiums to BC.
So far, OK, but much more money than I was paying before.
The problem is some people will sign up for Obamacare plans, pay a month's premium, then not pay any more. With a backlog of claims, the doctor won't get paid when the insurance lapses.
So a doctor will be VERY picky about who he decides to accept an "Obamacare" plan card from.
New patients are going to have a very hard time.
Expect a LOT of docs to simply not accept it, as is happening in CA.
I try to s-l-o-w-l-y explain to people that having a card DOESN'T mean actually getting healthcare.
