In Sick Around the World, FRONTLINE teams up with veteran Washington Post foreign correspondent T.R. Reid to find out how five other capitalist democracies -- the United Kingdom, Japan, Germany, Taiwan and Switzerland -- deliver health care, and what the United States might learn from their successes and their failures.

Reid's journey then takes him to Germany, the country that invented the concept of a national health care system. For its 80 million people, Germany offers universal health care, including medical, dental, mental health, homeopathy and spa treatment. Professor Karl Lauterbach, a member of the German parliament, describes it as "a system where the rich pay for the poor and where the ill are covered by the healthy." As they do in Japan, medical providers must charge standard prices. This keeps costs down, but it also means physicians in Germany earn between half and two-thirds as much as their U.S. counterparts.

How does Germany deliver healthcare to all its citizens?

Percentage of GDP spent on health care: 10.7

Average family premium: $750 per month; premiums are pegged to patients' income.

Co-payments: 10 euros ($15) every three months; some patients, like pregnant women, are exempt.

What is it? Germany, like Japan, uses a social insurance model. In fact, Germany is the birthplace of social insurance, which dates back to Chancellor Otto von Bismarck. But unlike the Japanese, who get insurance from work or are assigned to a community fund, Germans are free to buy their insurance from one of more than 200 private, nonprofit "sickness funds." As in Japan, the poor receive public assistance to pay their premiums.

How does it work? Sickness funds are nonprofit and cannot deny coverage based on preexisting conditions; they compete with each other for members, and fund managers are paid based on the size of their enrollments. Like Japan, Germany is a single-payment system, but instead of the government negotiating the prices, the sickness funds bargain with doctors as a group. Germans can go straight to a specialist without first seeing a gatekeeper doctor, but they may pay a higher co-pay if they do.

What are the concerns? The single-payment system leaves some German doctors feeling underpaid. A family doctor in Germany makes about two-thirds as much as he or she would in America. (Then again, German doctors pay much less for malpractice insurance, and many attend medical school for free.) Germany also lets the richest 10 percent opt out of the sickness funds in favor of U.S.-style for-profit insurance. These patients are generally seen more quickly by doctors, because the for-profit insurers pay doctors more than the sickness funds.
