When George W. Bush and congressional Republicans (and a handful of bought-off Democrats) created Medicare Advantage in 2003, it was the fulfillment of half of Bush’s goal of privatizing Social Security and Medicare, dating all the way back to his unsuccessful run for Congress in 1978 and a main theme of his second term in office.

Medicare Advantage is not Medicare. These plans are private health insurance provided by private corporations, who are then reimbursed at a fixed rate by the Medicare trust fund regardless of how much their customers use their insurance. Thus, the more they can screw their customers and us taxpayers by withholding healthcare payments, the more money they make.

With real Medicare, if your doctor says you need a test, procedure, scan, or any other medical intervention you simply get it done and real Medicare pays the bill. No muss, no fuss, no permission needed. Real Medicare always pays, and if they think something’s not kosher, they follow up after the payment’s been made so as not to slow down the delivery of your healthcare.

With Medicare Advantage, however, you’re subject to “pre-clearance,” meaning that the insurance company inserts itself between you and your doctor: You can’t get the medical help you need until or unless the insurance company pre-clears you for payment.
