I would suggest there is a second phenomenon. That is Dr’s, GP’s and specialists, are becoming part of large group practices.
The groups offer economies of scale and can deal with the documentation and billing with more skill and efficiency than a small practice. This trend is not all the fault of Obamadon’tcare and was in process before.
Just as mom and pop stores and established distributors bacame uncompetative, so it is with health care.
That has been going on for years and Obomacare is just the last mortal stab. We have been doing the insurance and .gov paper work for them free for years. That is a consequence of .gov and people in General. Now,with elec medical record costs it is just too much. When I started Practice our overhead was 54% now it in the 70’s% range. Not worth it.
