You buy the insurance for whichever state you LIVE in. If you're moving to MA, you can apply for MA health insurance, but expect to pay A LOT more for the same coverage.
NO, it does NOT work the same in different states, because each state has different requirements. Insurance is regulated on a state by state basis. MA requires that the insurance company take you, but they can charge WHATEVER rate they want, to cover that preexisting condition. And, in general, MA's health insurance rates are the highest in the nation, due to their "reform".
