By Jay MacDonald - It almost looked like junk mail. If I hadn't already been writing for months about a stealthy little health care reform perk known as the medical loss ratio rebate, I might have disposed of it unopened.

Instead, I ripped into it. Yes! A check for $803, no strings attached, courtesy of my now-former health insurance company.

I was one of approximately 12.8 million Americans who can expect to receive a whopping $1.1 billion in rebates from insurers who spent more on things like administrative costs and executive bonuses than the Affordable Care Act allows.

The medical loss ratio provision of the law, which kicked in last year, requires insurers who spend less than 80 percent of your premium dollars (85 percent for employer plans) directly on your health care to refund the difference to you every Aug. 1.

Self-employed workers who purchase their own policies are most likely to receive a rebate. When rebates are sent to employers, some may choose to put them toward future premium costs rather than return them to their employees...

If you would like to spoil the will-I-get-one surprise (and avoid inadvertently tossing away your rebate with the flyers), simply log onto Healthcare.gov, enter your insurance company or state, and you'll find a list of insurers in your state, their MLR ratios and the average rebate if any that they owe their customers.
