For a patient’s knee replacement, Medicare will pay a hospital $17,000. The same hospital can get more than twice as much, or about $37,000, for the same surgery on a patient with private insurance.
Or take another example: One hospital would get about $4,200 from Medicare for removing someone’s gallbladder. The same hospital would get $7,400 from commercial insurers.
The yawning gap between payments to hospitals by Medicare and by private health insurers for the same medical services may prove the biggest obstacle for advocates of “Medicare for all,” a government-run system.
If Medicare for all abolished private insurance and reduced rates to Medicare levels — at least 40 percent lower, by one estimate — there would most likely be significant changes throughout the health care industry, which makes up 18 percent of the nation’s economy and is one of the nation’s largest employers.
Some hospitals, especially struggling rural centers, would close virtually overnight, according to policy experts.
Others, they say, would try to offset the steep cuts by laying off hundreds of thousands of workers and abandoning lower-paying services like mental health.
he prospect of such violent upheaval for existing institutions has begun to stiffen opposition to Medicare for all proposals and to rattle health care stocks. Some officials caution that hospitals providing care should not be penalized in an overhaul.
Dr. Adam Gaffney, the president of Physicians for a National Health Program, warned advocates of a single-payer system like Medicare for all not to seize this opportunity to extract huge savings from hospitals. “The line here can’t be and shouldn’t be soak the hospitals,” he said.
“You don’t need insurance companies for Medicare for all,” Dr. Gaffney added. “You need hospitals.”
Soaring hospital bills and disparities in care, though, have stoked consumer outrage and helped to fuel populist support for proposals that would upend the current system. Many people with insurance cannot afford a knee replacement or care for their diabetes because their insurance has high deductibles.
Proponents of overhauling the nation’s health care argue that hospitals are charging too much and could lower their prices without sacrificing the quality of their care. High drug prices, surprise hospital bills and other financial burdens from the overwhelming cost of health care have caught the attention (and drawn the ire) of many in Congress, with a variety of proposals under consideration this year.
But those in favor of the most far-reaching changes, including Senator Bernie Sanders, who unveiled his latest Medicare for all plan as part of his presidential campaign, have remained largely silent on the question of how the nation’s 5,300 hospitals would be paid for patient care. If they are paid more than Medicare rates, the final price tag for the program could balloon from the already stratospheric estimate of upward of $30 trillion over a decade. Senator Sanders has not said what he thinks his plan will cost, and some proponents of Medicare for all say these plans would cost less than the current system.
The nation’s major health insurers are sounding the alarms, and pointing to the potential impact on hospitals and doctors. David Wichmann, the chief executive of UnitedHealth Group, the giant insurer, told investors that these proposals would “destabilize the nation’s health system and limit the ability of clinicians to practice medicine at their best.”
Hospitals could lose as much as $151 billion in annual revenues, a 16 percent decline, under Medicare for all, according to Dr. Kevin Schulman, a professor of medicine at Stanford University and one of the authors of a recent article in JAMA looking at the possible effects on hospitals.
“There’s a hospital in every congressional district,” he said. Passing a Medicare for all proposal in which hospitals are paid Medicare rates “is going to be a really hard proposition.”
Richard Anderson, the chief executive of St. Luke’s University Health Network, called the proposals “naïve.” Hospitals depend on insurers’ higher payments to deliver top-quality care because government programs pay so little, he said.
“I have no time for all the politicians who use the health care system as a crash-test dummy for their election goals,” Mr. Anderson said.
The American Hospital Association, an industry trade group, is starting to lobby against the Medicare for all proposals. Unlike the doctors’ groups, hospitals are not divided. “There is total unanimity,” said Tom Nickels, an executive vice president for the association.
“We agree with their intent to expand coverage to more people,” he said. “We don’t think this is the way to do it. It would have a devastating effect on hospitals and on the system over all.”
Rural hospitals, which have been closing around the country as patient numbers dwindle, would be hit hard, he said, because they lack the financial cushion of larger systems.
Big hospital systems haggle constantly with Medicare over what they are paid, and often battle the government over charges of overbilling. On average, the government program pays hospitals about 87 cents for every dollar of their costs, compared with private insurers that pay $1.45.
Some hospitals make money on Medicare, but most rely on higher private payments to cover their overall costs.
Medicare, which accounts for about 40 percent of hospital costs compared with 33 percent for private insurers, is the biggest source of hospital reimbursements. The majority of hospitals are nonprofit or government-owned.
The profit margins on Medicare are “razor thin,” said Laura Kaiser, the chief executive of SSM Health, a Catholic health system. In some markets, her hospitals lose money providing care under the program.
She says the industry is working to bring costs down. “We’re all uber-responsible and very fixated on managing our costs and not being wasteful,” Ms. Kaiser said.
“If you’re in a consolidated market, you are a monopolist and are setting the price,” said Mark Miller, a former executive director for the group that advises Congress on Medicare payments. He describes the prices paid by private insurers as “completely unjustified and out of control.”
Many hospitals have invested heavily in amenities like single rooms for patients and sophisticated medical equipment to attract privately insured patients. They are also major employers.
“You would have to have a very different cost structure to survive,” said Melinda Buntin, the chairwoman for health policy at the Vanderbilt University School of Medicine. “Everyone being on Medicare would have a large impact on their bottom line.”
People who have Medicare, mainly those over 65 years old, can enjoy those private rooms or better care because the hospitals believed it was worth making the investments to attract private patients, said Craig Garthwaite, a health economist at the Kellogg School of Management at Northwestern University. If all hospitals were paid the same Medicare rate, the industry “should really collapse down to a similar set of hospitals,” he said.
Whether hospitals would be able to adapt to sharply lower payments is unclear.
“It would force health care systems to go on a very serious diet,” said Stuart Altman, a health policy professor at Brandeis University. “I have no idea what would happen. Nor does anyone else.”
But proponents should not expect to save as much money as they hope if they cut hospital payments. Some hospitals could replace their missing revenue by charging more for the same care or by ordering more billable tests and procedures, said Dr. Stephen Klasko, the chief executive of Jefferson Health. “You’d be amazed,’ he said.
While both the Medicare-for-all bill introduced by Representative Pramila Jayapal, Democrat of Washington, and the Sanders bill call for a government-run insurance program, the Jayapal proposal would replace existing Medicare payments with a whole new system of regional budgets.
“We need to change not just who pays the bill but how we pay the bill,” said Dr. Gaffney, who advised Ms. Jayapal on her proposal.
Hospitals would be able to achieve substantial savings by scaling back administrative costs, the byproduct of a system that deals with multiple insurance carriers, Dr. Gaffney said. Under the Jayapal bill, hospitals would no longer be paid above their costs, and the money for new equipment and other investments would come from a separate pool of money.
But the Sanders bill, which is supported by some Democratic presidential candidates including Senators Kirsten Gillibrand of New York, Cory Booker of New Jersey, Elizabeth Warren of Massachusetts and Kamala Harris of California, does not envision a whole new payment system but an expansion of the existing Medicare program. Payments would largely be based on what Medicare currently pays hospitals.
Some Democrats have also proposed more incremental plans. Some would expand Medicare to cover people over the age of 50, while others wouldn’t do away with private health insurers, including those that now offer Medicare plans.
Even under Medicare for all, lawmakers could decide to pay hospitals a new government rate that equals what they are being paid now from both private and public insurers, said Dr. David Blumenthal, a former Obama official and the president of the Commonwealth Fund.
“It would greatly reduce the opposition,” he said. “The general rule is the more you leave things alone, the easier it is.”
