The reason that waiting lists are so long in Massachusetts is because doctors are now forced to accept Mass Health. What you'll hear when trying to make an appointment is "we are not taking new patients" or "we can get you in 2-6 months from now". Hospitals have always accepted Mass Health but private practitioners rarely would. There may be more people with insurance now but it's not the type of insurance anyone with a decent employer sponsored plan would call insurance. 10,000 dollar deductible for instance on a 650 per month plan.
