However, the Congressional Budget Office (CBO) has found that administrative costs under the public Medicare plan are less than 2 percent of expenditures, compared with approximately 11 percent of spending by private plans under Medicare Advantage. This is a near perfect apples to apples comparison of administrative costs, because the public Medicare plan and Medicare Advantage plans are operating under similar rules and treating the same population.
(And even these numbers may unduly favor private plans: A recent General Accounting Office report found that in 2006 Medicare Advantage plans spent 83.3 percent of their revenue on medical expenses, with 10.1 percent going to non-medical expenses and 6.6 percent to profitsa 16.7 percent administrative share.)
The CBO study suggests that even in the context of basic insurance reforms, such as guaranteed issue and renewability, private plans administrative costs are higher than the administrative costs of public insurance. The experience of private plans within FEHBP carries the same conclusion. Under FEHBP, the administrative costs of Preferred Provider Organizations (PPOs) average 7 percent, not counting the costs of federal agencies to administer enrollment of employees. Health Maintenance Organizations (HMOs) participating in FEHBP have administrative costs of 10 to 12 percent.
In international perspective, the United States spends nearly six times as much per capita on health care administration as the average for Organization for Economic Cooperation and Development (OECD) nations. Nearly all of this discrepancy is due to the sales, marketing, and underwriting activities of our highly fragmented framework of private insurance, with its diverse billing and review practices.
