Seniors also benefit from the law through better Medicare coverage for those with high prescription costs, and no copayments for preventive care. But hospitals, nursing homes, and many other service providers may struggle once the Medicare cuts used to finance the law really start to bite.
Illegal immigrants are not entitled to the new insurance coverage under the law, and will remain one of the biggest groups uninsured.
Obama's law is by no means the last word on health care. Experts expect costs to keep rising, meaning that lawmakers will have to revisit the issue perhaps as early as next year, when federal budget woes will force them to confront painful options for Medicare and Medicaid, the giant federal programs that cover seniors, the disabled, and low-income people.
The health care overhaul focus will now quickly shift from Washington to state capitals. Only 14 states, plus Washington, D.C., have adopted plans to set up the new health insurance markets called for under the law. Called exchanges, the new markets are supposed to be up and running on Jan. 1, 2014. People buying coverage individually, as well as small businesses, will be able to shop for private coverage from a range of competing insurers.
Most Republican-led states, including large ones such as Texas and Florida, have been counting on the law to be overturned and have failed to do the considerable spade work needed to set up exchanges. There's a real question about whether they can meet the deadline, and if they don't, Washington will step in and run their exchanges for them.
In contrast to the states, health insurance companies, major employers, and big hospital systems are among the best prepared. Many of the changes called for in the law were already being demanded by employers trying to get better value for their private health insurance dollars.
"The main driver here is financial," said Dr. Toby Cosgrove, CEO of the Cleveland Clinic, which has pioneered some of the changes. "The factors driving health care reform are not new, and they are not going to go away."
Justice Ginsburg said the court should have upheld the entire law as written without forcing any changes in the Medicaid provision. She said Congress' constitutional authority to regulate interstate commerce supports the individual mandate. She warned that the legal reasoning, even though the law was upheld, could cause trouble in future cases.
"So in the end, the Affordable Health Care Act survives largely unscathed. But the court's commerce clause and spending clause jurisprudence has been set awry. My expectation is that the setbacks will be temporary blips, not permanent obstructions," Ginsburg said in a statement she, too, read from the bench.
