Will Obama's Health Care Plan end private coverage?

The Lewin Group, a health care consultancy, has determined that private coverage would be dramatically scaled back if a national plan is enacted. From reasononline:

Sadly, we are already well on our way to a wholly government-run health insurance system. After fall, about 47 percent of all health care expenses today are paid for by federal, state, and local governments, e.g., Medicare, Medicaid, and State Children's Health Insurance Program (SCHIP). Establishing a public insurance scheme would dramatically increase the percentage of health care that is paid for by the federal government.

In April, the Lewin Group, a health care consultancy, issued an analysis of how the public health insurance option plan might affect the provision of private health insurance. Currently about 170 million Americans are covered by private health insurance plans, mostly through their employers.

The Lewin Group crunched the numbers through their health care model and found that premiums for the public option plan would be 30 to 40 percent lower than private plans. Sounds great, right? But these lower premiums are essentially achieved by imposing price controls. The Lewin Group assumed that the public option plan will pay doctors and hospitals at the same rates they currently receive from Medicare. And Medicare reimbursements already run 71 percent and 81 percent below what private health plans pay hospitals and doctors, respectively.

First, the somewhat good news. Lower public option premiums and an increase in Medicaid coverage would attract 28 million of the 48 million Americans who currently are not covered by health insurance. Now the bad news. The lower premiums would encourage employers to drop private health insurance and put their employees into the public plan. Overall, the Lewin Group estimates that if Medicare reimbursement rates are imposed, the number of Americans with private health insurance would decline by almost 120 million, leaving only 50 million Americans in the private insurance market.

Defenders of the public option quickly point out that Kennedy's American Health Choices Act promises to pay health care providers 10 percent more than Medicare. But as the Cato Institute's Michael Tanner noted at Cato@Liberty, "When Medicare began, proponents promised it would reimburse at the same rate as insurance. That promise didn't last long." In fact, in his letter to Kennedy and Baucus, Obama explicitly endorsed the idea of setting mandatory physician and hospital reimbursement rates through the Medicare Payment Advisory Commission. In other words, the payments would no longer be merely advisory.
