Hadley Heath's health insurance plan seemed to have it all. A low deductible, low monthly premium, and comprehensive coverage that even included free preventative care.

But Heath's insurer, CareFirst Blue Cross Blue Shield just sent her a letter, announcing they will terminate her plan because it lacks "Essential Health Benefits," mandated under the Affordable Care Act.

Health is one of millions of people holding individual health insurance plans who are about to lose them. Florida Blue will drop 300,000 policies that don't meet the ACA requirements, while 150,000 Oregon residents who are signed up under individual plans will also lose their current coverage. California's Blue Shield sent termination notices to 119,000 policy holders, an official told the Washington Examiner.

Many of those policy holders are now facing higher deductibles and higher monthly premiums if they purchases a new policy under Obamacare.
