Could someone please explain to Representative Kucinich how insurance works?

Rep. Dennis Kucinich (D-OH) yesterday requested that six top insurance company executives appear before his subcommittee to explain how they do business. Kucinich has asked the six executives from Aetna, WellPoint, Cigna, Humana, Hemingway Health Care, and United Health to “put into context anecdotes of claims denials, deferrals, and policy rescission by insurers.”

He should save himself some trouble and just look it up on the Web. When the executives show up, they should ask him about anecdotes that doctors are refusing to accept Medicare and Medicaid patients because the reimbursements are so low.
