Among the $500 billion in Medicare cuts that will provide the bulk of the financing for Obama's health care plan is a $160 billion to $180 billion cut in the Medicare Advantage program, which offers a range of benefits not available to beneficiaries under basic Medicare.

Medicare Advantage should be Obama's favorite program. It combines all the elements he likes -- premiums are subsidized for low-income elderly, and the companies negotiate low-priced, managed care that emphasizes prevention, treatment of chronic conditions and coordination among doctors. As a result, its costs on the one hand and its premiums on the other are both much lower than with conventional insurance.

Ten million primarily low-income elderly have voluntarily enrolled in Medicare Advantage and realize savings of about $1,000 annually in enhanced benefits over and above what Medicare itself provides. These extra benefits include reductions in out-of-pocket costs and comprehensive drug coverage, vision, dental and hearing benefits, wellness programs (like gym memberships), and disease management and care coordination programs.

Medicare Advantage, which gained momentum during the Bush-43 years, essentially implements all the economies and efficiencies that Obama preaches nonstop. Doctors speak to one another, duplication is avoided, care is managed, and there is an emphasis on prevention.

The alternative to Medicare Advantage is Medicare supplement plans, popularly called Medigap coverage. But these conventional health insurance policies offer fewer benefits at higher premiums. They offer no care coordination, no chronic care management, no pay-for-performance incentives. They have no way to control costs. They just write out checks.

Because Medicare Advantage negotiates payment levels and saves money through bulk purchasing, inpatient costs run 20 percent to 25 percent lower than under Medigap insurance. More patients are handled through outpatient care. X-rays and other radiation cost 10 percent to 20 percent less, and durable medical equipment like wheelchairs, walkers and oxygen bottles run one-fifth less than with conventional insurance policies.
