During the 1930s and '40s, Kaiser wanted to make sure the workers at his Richmond, Calif., shipyard stayed healthy. Kaiser Permanente then opened its doors to the public in 1945.
That's a key difference from other providers: Kaiser Permanente owned its own hospitals and clinics and directly employed physicians. Other insurers had to negotiate with outside hospitals and doctors demanding ever-higher payments. Without those burdens, Kaiser could offer health coverage that was high-quality and less expensive than conventional insurers.
Today, it's a different story, says Mark Smith, head of the California HealthCare Foundation. The organization is no longer the bargain it used to be, he says, possibly because of what economists call "shadow pricing."
"If your competitor takes $4 to make a banana and it only takes you $2 to make a banana, you price your banana at $3.95 and you pocket the rest," Smith says.
It's difficult to discern just how Kaiser fares against other companies since negotiations between health plans and employers are largely confidential. Kaiser says its costs increase by about 5 percent each year. But some of Kaiser's biggest customers say their premiums have jumped much higher, in some cases 20 percent.
This may stem in part from the very trait that makes Kaiser Permanente so efficient: The health maintenance organization, unlike other providers, doesn't have a menu of fees.
Bob Kocher, a former health care adviser to President Obama, says Kaiser's model was at the back of policymakers' minds when they wrote what are essentially Kaiser look-alikes into the health overhaul law.
Kaiser hospitals have shown they can deliver top-shelf care for happy-hour prices. Recent Medicare data show all but one of Kaiser's hospitals cost significantly less than the national average. And the company's electronic medical record system is one of the most advanced in the world and has largely eliminated duplicative tests.
But Kocher suspects that as more doctors and hospitals band together into Kaiser Mini-Me's, Kaiser Permanente could face more competition.
Kaiser Permanente, meanwhile, is marching east. It's expanding in the Washington, D.C., area, as well as in Georgia. Some health policy experts assert that the company is setting its premiums, in part, to underwrite this expansion.
Halvorson says Kaiser Permanente spends its surplus to benefit its customers.
"We use our money to invest in our care system; we use our money to invest in our computer systems," he says. "We reinvest money in hospitals and clinics and that's the only use of the money."
Halvorson contends if all Americans got their care at Kaiser-like facilities, the U.S. would save hundreds of billions of dollars in health care costs. Others are less convinced. The cautionary tale of Kaiser Permanente, they say, is that even under the best circumstances, U.S. health care prices may still be untamable.
