I get a lot of questions about the success and failures of the Massachusetts health plan. More to the point, I see a lot of incomplete information about the plan, and vague speculation. That's understandable, until this month, there wasn't any reliable data out of the experiment. But thanks to the Urban Institute, we've got the first round of numbers, and I've written up a sort of progress report on the plan: Where it's succeeded, where it's failed, and what it hasn't yet tried. Update: In the article, I note that Massachusetts is taking on cost control next. Charles Blandy at BlueMassGroup notes that the Senate President Therese Murray has written and passed a bill on cost control, and next it'll go through the House. I haven't read it yet, but for those with some time, the legislation is here.
