Hi Clo:
Romneycare was pretty slick and unintrusive for most of us because Ma. was advantaged in several ways. It only becomes apparent at income tax time when we must prove we have health insurance. I've helped several low-income families sign up for subsidized MassHealth with little problem also.
Insurance providers under Obamacare seem excessively pre-occupied with obtaining formal identification and recorded agreements to buy their product, probably because of new customers and folks changing to unfamiliar companies and products.
I was extremely satisfied with our old carrier, Tufts, which is no longer available. They just took care of everything with no particpation on my part.
