Roughly two-thirds of the U.S. populationhas health coverage through private insurance companies. Despite paying about $1,600 a year out of pocket on deductibles, copayments, and coinsurance, Americans have no guarantee their insurer will cover the cost of their care. Because insurance companies in the United States seek to maximize their profits, they have an incentive to deny payment for some services, even for recommended care, and to raise monthly premiums and out-of-pocket costs.

Switzerland has also struggled to make health care affordable for all residents, withone of the highest levels of out-of-pocket spending per person in the world, comparable to the U.S. average. Like the U.S., it relies largely on private health insurance, with residents choosing among competing insurers. But unlike the U.S., Switzerland bars insurers from profiting off basic plans. That difference helps explain why nearly a third of the U.S. population has medical bills or debt they are paying off over time, while only 2 percent of the Swiss population reports the same problem.1
Regulating Private Insurers in Switzerland
Switzerland’s current system of mandatory basic health insurance (obligatorische Krankenpflegeversicherung, or OKP) was established in 1996 and requires all residents to purchase health insurance from authorized private insurers. Today, 100 percent of the population is covered through OKP, and everyone has access to the same nationally defined baseline benefits package, regardless of insurer. Because everyone is enrolled, costs are spread out across healthier residents and those who need more costly care.
Premiums are set by insurers but subject to federal approval. All plans include a minimum annual deductible of CHF 300 (USD 340), 10 percent coinsurance capped at CHF 700 (USD 794) annually, and a daily hospital fee; adults can choose plans with deductibles up to CHF 2,500 (USD 2,835) in exchange for lower premiums. The Swiss government also caps the price of services and what insurers pay providers to control costs.
While the federal government sets these baseline standards, it does not sell insurance directly. Residents choose among private insurers based on premiums, deductibles, provider restrictions, and networks, while guaranteed a core set of protections. Those who don’t enroll are assigned a planby their local government and are responsible for late fees and past-due bills.
The most fundamental feature of the Swiss insurance market is that insurers are prohibited from earning a profit on basic health plans and must use a community-rating premium structure that shares costs between sicker and healthier individuals. Any surplus collected from basic premiums that exceeds paid claims must either beheld in reserve to cover future costs or be returned to policyholders. Insurers also cannot deny coverage for any medically necessary care included in the basic package.
Insurance companies can, however, profit from supplementary private insurance, which covers services such as dental care and private or semiprivate hospital rooms. For these plans, insurers can reject applicants and vary premiums based on health status, age, and sex.
Despite federal regulations, affordability remains a major hurdle in the Swiss health system. Out-of-pocket spending is among the highest in the world, and premiums, which do not vary with income, can burden families who do not qualify for subsidies. Still, the system rests on a strong commitment to social solidarity, and some Swiss see these costs as the price of insuring everyone, even the most vulnerable. Because deductibles and coinsurance on basic plans are capped each year and claims for covered care cannot be refused, few residents fall into medical debt.
America’s Underregulated Private Insurance Market
The U.S. private insurance market is not entirely unregulated: the 2010 Affordable Care Act (ACA) prohibits insurers from denying enrollment based on preexisting conditions, age, or sex. The ACA also requires plans to cover essential health benefits and cap out-of-pocket spending, and it provides income-based subsidies for coverage bought through the marketplaces.
Since private insurers are permitted to operate for profit, they still have an incentive to limit what they pay out to maximize their earnings. While people cannot be denied enrollment, insurers can delay payment for doctor-recommended services or deny claims altogether by arguing the care was not medically necessary or by citing other technicalities.
In 2025, one in five U.S. working-age adults with private insurance said they or a family member had been denied treatment their doctor recommended in the past year, and about 40 percent of them said the denial led to delayed care. More than two in five adults whose claim was denied reported it led to medical debt they are still paying off. In one survey, most working-age adults with private coverage who were paying off medical bills or debt blamed insurance companies.

While both Switzerland and the United States have an individual mandate requiring residents to enroll in a health plan — which is necessary for maintaining balanced risk pools — enforcement differs greatly. Since 2019, the ACA’s federal tax penalty for going without coverage has been $0, and only four states and Washington, D.C., impose their own financial penalties.
In both countries, a person’s insurer, out-of-pocket spending, and provider networks vary widely. But federal regulation in Switzerland ensures all residents have minimum coverage, without fear that insurers will create obstacles to care in pursuit of their own profit. American patients have far fewer protections against companies that refuse or stall payment for care.
