If you are ever are in the hospital for a pricey treatment, you may find your insurance company is trying to avoid paying for it. The method they use is called rescision. It is a practice the insurance companies don't want to talk about.

Here's how it works. When the bills are submitted to the insurance company, either for costly procedures or even costly medications, they review your policy and look for any errors. If an error is found, even if it's a simple oversight on your part, your policy is rescinded and you are stuck paying the bill.

Some insurance have been met with hefty lawsuits after rescinding policies. If you find your insurance company is trying to squeeze you out, you may want top follow-up and see if you have any recourse. The insurance company may be required to prove that you intentionally falsified your forms.
