A case study in 'cost-control.'
The problem is that what "works best" isn't the same for everyone. While not painless or risk free, virtual colonoscopy might be better for some patients -- especially among seniors who are infirm or because the presence of other diseases puts them at risk for complications. Ideally doctors would decide with their patients. But Medicare instead made the hard-and-fast choice that it was cheaper to cut it off for all beneficiaries. If some patients are worse off, well, too bad.
Medicare is already the country's largest purchaser of health care. Private carriers generally adopt its rates and policies, and the virtual colonoscopy decision may run this technology out of the marketplace. Now multiply that by the new "public option" that Democrats favor, which would transfer millions of patients to a new insurance program managed by the federal government.
…scarcity forces choices. As the Medicare trustees note in their report, the tax increases necessary to fund merely the current benefit schedule for the elderly would cripple the economy. The far more expensive public option will not turn into a pumpkin when cost savings do not materialize. At that point, government will clamp down with price controls in the form of lines and rock-bottom reimbursement rates.
