MIAMI (AP) — Dean Griffin liked the health insurance he purchased for himself and his wife three years ago and thought he'd be able to keep the plan even after the federal Affordable Care Act took effect.

But the 64-year-old recently received a letter notifying him the plan was being canceled because it didn't cover certain benefits required under the law.

The Griffins, who live near Philadelphia on the Delaware border, pay $770 monthly for their soon-to-be-terminated health care plan with a $2,500 deductible. The cheapest plan they found on their state insurance exchange was a so-called bronze plan charging a $1,275 monthly premium with deductibles totaling $12,700. It covers only providers in Pennsylvania, so the couple wouldn't be able to see the doctors in Delaware whom they've used for more than a decade.
