Lke our President said, you get to keep your doctor. Except for Kaiser that has their own, I have seen doctors accepting all the major plans. There may be a few isolated caes where a doctor has had a problem with some insurer, but the majors all are usually accepted. I have had blue shield, health net, and united all with the same doctor. Medicare is a different story.
99% of the republican talk on ObamaCare is a lie.
