Now that Massachusetts requires state residents to be covered by health insurance, apparently there are not enough primary care physicians to go around. From this NPR article:
The law, passed in 2006, requires most state residents to be covered either through a state-subsidized plan, an employer-sponsored plan or an individual policy. Jacqueline Spain, medical director for Holyoke Health Center, said, “It’s entirely reasonable for somebody who’s now got insurance and maybe has a whole list of things that’s worried them and troubled them” to “expect that they should be able to go out in the market and get all of that care. There just aren’t enough [primary care physicians] to give it to them.” She said about 1,600 people currently are on the facility’s waiting list and patients must wait an average of four months to be seen.
