Robert J. Samuelson: Ryan's Medicare plan might work, a study says

WASHINGTON —

Overlooked in the furor surrounding Paul Ryan's Medicare proposal — a plan, it should be recalled, that wouldn't start until 2023 and even then would affect only new beneficiaries — is a just-published study in The Journal of the American Medical Association (JAMA) suggesting that, well, Ryan might be right. The study finds that a voucher-type system might noticeably reduce costs compared to "traditional" fee-for-service Medicare. Three Harvard economists did the study, including one prominent supporter of President Obama's health care overhaul.

The study compared the costs of traditional Medicare with Medicare Advantage, a voucher-like program that now enrolls about 25 percent of beneficiaries. Medicare Advantage has cost less for identical coverage. From 2006 to 2009, the gap averaged 11 percent between traditional Medicare and voucher plans that, under the proposal by Ryan and Sen. Ron Wyden, D-Ore., would serve as a price "benchmark."

The central issue here is whether the runaway costs of the health sector, comprising nearly one-fifth of the economy, can be controlled without eroding medical quality. Almost everyone agrees that the delivery system — the amalgam of hospitals, clinics, doctors and nurses — should be reorganized to lower costs and eliminate unneeded care. The question is how.

One group favors market-like mechanisms. Consumers would receive vouchers, either payments or tax credits, to buy coverage. The theory: as people shop for low-cost and high-quality plans, competition forces the delivery system to restructure. Hospitals, doctors, insurers create more efficient networks with more coordinated care than today's fee-for-service system. By contrast, fee-for-service reimburses doctors and hospitals for services they perform; this encourages unneeded tests and procedures.

The JAMA study doesn't surprise advocates of this "consumer driven" health care. "Medicare fee-for-service is an inefficient way to deliver care," says James Capretta, associate director of the Office of Management and Budget from 2001 to 2004. "It's an engine for volume-driven spending." Cost savings under a full-fledged voucher system would be much larger, he argues, because Medicare Advantage's modest size has created only "muted competition."

Medicare Advantage reinforces another bit of real-word evidence for market-like policies. This is the Medicare drug benefit (Part D), launched in 2006 with a voucher approach. In 2012, beneficiaries could choose from at least two-dozen plans. Part D's costs have been about 30 percent below early estimates by the Congressional Budget Office, though vouchers are not the only reason (more generic drugs is another). In 2013, average monthly premiums — the part paid by recipients — are projected to stay at $30 for a third straight year.

The other way to control costs is regulation, as embodied in the Affordable Care Act (ACA). One argument for this is that cost savings from vouchers are a statistical mirage. Harvard health economist David Cutler — a co-author of the JAMA study and an outspoken supporter of the ACA — thinks this is possible. Medicare Advantage's lower costs might stem mostly from healthier patients, who use fewer medical services. It's unclear that statistical "risk adjustments" eliminate all these differences, he says.

Lower reimbursement rates are the most common form of cost regulation. The ACA cuts $700 billion from Medicare over a decade by slashing payment rates for hospitals and other providers. But reimbursement reductions don't change the delivery system. Providers often react by increasing the volume of services; the system becomes more wasteful. (The Medicare cuts don't actually reduce health spending; they just transfer funds from Medicare to spending mandated by the ACA.)
