On Monday, Mr. Obama praised health industry groups for coming forward with the offier.
Mr. Obama appeared at the White House with an array of industry figures, including union representatives, and called it the occasion "historic."
The industry figures pledged to the president that they would voluntarily slow their rate increases over the next 10 years.
Mr. Obama said the step the industry took Monday must be carried out as part of "a broader effort" to change the health care system, keep costs under control and provide health insurance for the some 46 million Americans who do not now have it.
He said, "I will not rest until the dream of health care reform is achieved in the United States of America."
With this move, Mr. Obama picks up key private-sector allies that fought former President Bill Clinton's effort to overhaul health care. Although the offer from the industry groups doesn't resolve thorny details of a new health care system, it does offer the prospect of freeing a large chunk of money to help pay for coverage. And it puts the private-sector groups in a good position to influence the bill Congress is writing.
Six major groups pledged to cut the growth rate for health care by 1.5 percentage points each year.
Still, even Mr. Obama acknowledged that the step announced Monday would be meaningful into the future only if it is not a singular event, but part of a larger and successful effort toward universal health care coverage for Americans. He said the country "can, will and must" accomplish this goal by the end of the year.
"There's so much more to do," he said.
"We can't continue down the same dangerous road we've been traveling for so many years," Mr. Obama said. "Reform is not a luxury that can be postponed, but a necessity that cannot wait."
He indirectly criticized some of the groups at his side for killing the effort last time.
"All too often, efforts at reform have fallen victim to special interest lobbying aimed at keeping things the way they are, to political point-scoring that sees health care not as a moral issue or an economic issue, but as a wedge issue, and to a failure on all sides to come together on behalf of the American people," the president said.
Mr. Obama has offered an outline for overhauling the health care system, and he wants Congress to work out the details and pass legislation this year. His plan would build on the current system in which employers, government and individuals share responsibility for paying the cost and care is delivered privately. The government would play a stronger role by subsidizing coverage for many more people and spelling out stronger consumer protections.
The industry groups are trying to get on the administration bandwagon for expanded coverage now in the hope they can steer Congress away from legislation that would restrict their profitability in future years.
Insurers, for example, want to avoid the creation of a government health plan that would directly compete with them to enroll middle-class workers and their families. Drug makers worry that in the future, new medications might have to pass a cost-benefit test before they can win approval. And hospitals and doctors are concerned the government could dictate what they get paid to care for any patient, not only the elderly and the poor.
Mr. Obama has courted industry and provider groups, inviting their representatives to the White House. There's a sense among some of the groups that now may be the best time to act before public opinion, fueled by anger over costs, turns against them.
It's unclear whether the proposed savings will prove decisive in pushing a health care overhaul through Congress. There's no detail on how the savings pledge would be enforced. And, critically, the promised savings in private health care costs would accrue to society as a whole, not just the federal government. That's a crucial distinction because specific federal savings are needed to help pay for the cost of expanding coverage.
Indeed, costs have emerged as the most serious obstacle to Mr. Obama's plan. The estimated federal costs range from $1.2 trillion to $1.5 trillion over 10 years, and so far Mr. Obama has only spelled out how to get about half of that. Administration officials would not say Sunday how much they think Mr. Obama's plan will ultimately cost, but they indicated they were confident it can be paid for.
A reduction of 1.5 percentage points a year in the rate of increase in costs may not sound like much, but administration officials said it amounts to slowing the current 7 percent annual increase in costs by about one-fifth. That's significant when health care spending keeps running far ahead of inflation year after year.
They estimated, for instance, that five years from now, such private cost curbs could save a family of four an average of $2,500 a year in health care costs.
Administration officials said they didn't expect all the saving strategies to be announced Monday, nor did they have access to specifics on how the groups reached their estimates and analysis.
But the initial reaction was positive.
"While serious questions remain about the details, AARP believes the agreement of providers to slow the skyrocketing cost of health care is critical for the health reform we are all working toward," said John Rother, policy director for the seniors' lobby. "Reducing the skyrocketing cost of health care is the only way to create a health care system that works for all Americans; after all, what good is access to a system that we can't afford?"
Ron Pollack, director of Families USA, a liberal group that supports coverage for all, said the health insurance industry came up with the target of a 1.5-percentage-point reduction. Karen Ignagni, president of the insurers trade group, America's Health Insurance Plans, took the idea to other major interest groups, said Pollack, who was familiar with the talks among the industry groups.
"If these cost savings are truly achievable, this may be the most significant development on the road to health care reform," said Pollack. "It would cut costs for families and businesses and enable subsidies to be offered so everyone has access to quality, affordable health care."
The groups include the American Medical Association, the American Hospital Association, the Service Employees International Union, the California Hospital Association and the Greater New York Hospital Association, which represents facilities in four states.
Mr. Obama's plan envisions that people would be able to keep the coverage they now have. Those working for big companies probably would not see major changes.
But the self-employed and those working for small businesses would be able to get coverage through a new kind of insurance purchasing pool. Called an "exchange," the pool would offer stable rates and predictable benefits. Plans in the exchange wouldn't be able to deny coverage to those who are sick and would have to follow other new consumer protection rules.
Lawmakers in Congress are generally following Mr. Obama's outline, but the Senate plan is likely to go further by requiring all Americans to carry health insurance, much as states now require motorists to carry auto coverage. Democrats hope to get legislation to the floor this summer.
