A very important Washington Post editorial today:

THE ONLY THING more unsettling than watching legislative sausage being made is watching it being made on the fly. The 11th-hour "compromise" on health-care reform and the public option supposedly includes an expansion of Medicare to let people ages 55 to 64 buy into the program. This is an idea dating to at least the Clinton administration, and Senate Finance Committee Chairman Max Baucus (D-Mont.) originally proposed allowing the buy-in as a temporary measure before the new insurance exchanges get underway. However, the last-minute introduction of this idea within the broader context of health reform raises numerous questions -- not least of which is whether this proposal is a far more dramatic step toward a single-payer system than lawmakers on either side realize. The details of how the buy-in would work are still sketchy and still being fleshed out, but the basic notion is that uninsured individuals 55 to 64 who would be eligible to participate in the newly created insurance exchanges could choose instead to purchase coverage through Medicare. In theory, this would not add to Medicare costs because the coverage would have to be paid for -- either out of pocket or with the subsidies that would be provided to those at lower income levels to purchase insurance on the exchanges. The notion is that, because Medicare pays lower rates to health-care providers than do private insurers, the coverage would tend to cost less than a private plan. The complication is understanding what effect the buy-in option would have on the new insurance exchanges and, more important, on the larger health-care system.
