If you have no idea what you're paying good money for when you enroll in a health insurance plan, there's a good reason for that: insurers profit from your ignorance. And they're waging an intense, behind-the-scenes campaign to keep you in the dark.
In my first appearance before Congress after leaving the insurance industry, I told members of the Senate Commerce Committee that insurers intentionally make it all but impossible for consumers to find out in advance of buying a policy exactly what is covered and what isn't, and how much they'll be on the hook for if they get sick or injured. Insurers are quite willing to provide you with slick marketing materials about their policies, but those materials are notoriously skimpy when it comes to useful information. And the documents they provide after you enroll are so dense that few of us can understand them.
