European countries and Canada all have universal coverage. They also have private health insurance.
Presidential hopefuls in the Democratic primary have, in recent weeks, found themselves facing a new litmus test: Do they want to eliminate private health insurance?
Sen. Kamala Harris faced a straightforward version of this question and gave a straightforward response. “Let’s eliminate all that,” Harris said of private coverage.
Sen. Cory Booker faced a slightly more confusing version of this question and gave a slightly more confusing answer that indicated support for keeping certain parts of the health care system private.
An international perspective is helpful here. When you look out at the rest of the world — at the dozens of countries that run universal health care systems — you find that every universal health plan relies, in some form or another, on private insurance.
“Basically every single country with universal coverage also has private insurance,” says Gerard Anderson, a professor at Johns Hopkins University who studies international health systems. “I don’t think there is a model in the world that allows you to go without it.”
Other developed countries routinely use private insurance to fill in the gaps of their public plans or to offer patients a way to get to see a doctor a bit faster. Some countries, like Australia, even take aggressive steps like offering tax benefits to encourage citizens to enroll in private coverage alongside their public plan.
“Each country has figured out its own role for private insurance,” says Robin Osborn, a vice president at the nonprofit Commonwealth Fund, who studies international health systems. “In almost every system, it tends to not be controversial because the commitment to basic universal coverage is there.”
How other countries use private health insurance, it turns out, can actually can tell you a lot about what countries value in a health care system — and how they think access to care ought to be organized.
The three ways other countries use private health insurance
When you look out at our peer countries, you essentially see them using private health coverage in three distinctive ways.
First, there are some countries that require all citizens to enroll in health coverage run by private insurers. These insurers typically compete in a market with strict rules about what they must cover and how much different medical services cost.
The Netherlands and Israel are good examples of this type of system. In both countries, citizens are required to purchase coverage from a private plan. Somewhat coincidentally, the Netherlands and Israel both have four dominant health plans in their private markets.
In each case, the insurers are required to cover the same set of benefits and cannot charge higher premiums for the sick. But they can compete along other dimensions.
“They compete on what other benefits do they offer, and the price of the premium too,” Osborn says. “Generally, though, people don’t switch insurance very much. They tend to stick with their plans for a long time, even though they have the option to switch each year.”
The benefit these systems offer is primarily about choice: In Israel and the Netherlands, patients have multiple options for where they want to seek health coverage.
Second, there are some countries where private insurance supplements public insurance. It’s quite common for Canadians and Europeans to purchase supplemental insurance that covers things that the public plan won’t.
Sometimes this takes the form of supplemental insurance to pay for non-covered benefits. In Canada, for example, two-thirds of the population takes out private plans to cover vision, dental, and prescription drug benefits — none of which are included in the public plan. Thirty-nine percent of Danish citizens carry private coverage for non-covered benefits including physical therapy.
In other places, this takes the form of supplemental insurance to cover the cost-sharing included in the public plan. If you look at France, you see that 95 percent of the population takes out (or receives public subsidies for) private insurance to cover their copayments and deductibles.
Third, there are some countries where private insurance complements public insurance. In these places, residents buy private coverage to gain better, faster access to benefits that are covered in the public system.
Osborn points to England as an especially good example of this type of coverage. About 11 percent of the British population purchases complementary coverage that can get them faster access to specialty doctors or elective procedures.
“The UK is very committed to solidarity and equity in its health system, but at the same time they are still very comfortable with this private insurance role,” she says. “I think it operates as a safety valve. People use it for elective surgery, for something like a hip replacement where there might be a long wait list.”
Australia is another example of a country that has really embraced complementary coverage, to the point that 47 percent of the country’s residents carry private coverage alongside their public plans. The government actually encourages citizens to buy a private plan, offering tax rebates to those who enroll — and a lower lifetime premium for those who sign up before they’re 30.
Many countries combine these different types of private insurance, too. In the Netherlands, for example, private plans run the basic benefit package — and 84 percent of Dutch residents purchase an additional, supplementary plan to cover more benefits. Denmark has strong markets for both supplementary and complementary coverage, as do New Zealand and Australia.
Why we’re having a debate about eliminating private coverage in the United States
The debate we’re having around universal coverage in the United States right now often centers on the health care plan offered by Sen. Bernie Sanders (I-VT). His plan — which you can read a longer explainer of here — envisions government-run health insurance that covers a wide array of benefits including vision, dental, and prescription drugs. His plan has no cost-sharing for patients — meaning you don’t pay a copayment when you go to the doctor, nor do you have a deductible to hit before your benefits kick in.
The Sanders plan permits supplemental private insurance, the type that covers things that the public system doesn’t. But because the public insurance plan pretty much covers everything, it’s difficult to see what role it would play.
Here’s the thing: None of our peer countries have built a health care system like this. Canada, France, England, Australia, the Netherlands — all of them run health care systems that have gaps in coverage.
Not one of our peer countries has found a way to provide health care that covers all benefits at no cost to patients — the price is just prohibitive. Instead, most provide free or low-cost access to core medical services, while asking patients to kick in something for the parts the government can’t afford.
When you look at our peers, the key question doesn’t seem to be whether there will be private health insurance. Instead, the key question seems to be what role private health insurance will play. The answer to that question can often reflect a health system’s core values.
Take Canada, for example. That country outlaws complementary insurance. Any benefit covered in the public system — things like doctor visits and hospital stays — cannot be covered by a private provider there.
This reflects the Canadian system’s commitment to equality and fairness. As one scholar there memorably told the journalist T.R. Reid, “Canadians don’t mind waiting in lines, as long as the rich Canadian and the poor Canadian have to wait about the same amount of time.”
This is really different from the Australian system, where the government is expressly encouraging citizens to enroll in private coverage with various tax rebates and penalties. There, officials think they can alleviate burdens on the public system by building a robust private system in parallel.
It’s true that the Australians like their health care system more than Canadians like theirs — but it’s also true that wealthier Australians are more likely to enroll in private insurance than lower-income Australians, introducing an element of inequality that doesn’t exist in Canada. The health system you prefer turns on the values you hold.
“I think there are some basic policy issues that countries have to face,” says Anderson. “Should private insurance allow you to jump the queue? Should it allow you to get a private room? These are big policy debates in other countries.”
