Insurance companies are not allowed to have co-payments, caps, or deductibles, or to deny coverage to any person applying for a policy, or to charge anything other than their nationally set and published standard premiums. Therefore, every person buying insurance will pay the same price as everyone else buying the same policy, and every person will get at least the minimum level of coverage.
In the run-up to the 2016 Democratic National Convention, the Democratic Platform Committee approved a plank supporting the addition of a public option onto the Affordable Care Act. The decision was seen as a compromise measure between the Hillary Clinton campaign who during the 2016 presidential primaries advocated for keeping and reforming the ACA, and the Bernie Sanders campaign who advocated for repealing and replacing the ACA with a single-payer Medicare for All program. The Clinton campaign stated shortly before the plank was added that as president Clinton would "pursue efforts to give Americans in every state in the country the choice of a public-option insurance plan", while Bernie Sanders applauded the decision to "see that all Americans have the right to choose a public option in their health care exchange, which will lower the cost of healthcare". The call was echoed by President Obama, who in an article for the American Medical Association stated that Congress "should revisit a public plan to compete alongside private insurers in areas of the country where competition is limited."
The purpose behind the public option was to make more affordable health insurance for uninsured citizens who are either unable to afford the rates of or are rejected by private health insurers. Supporters argued that a government insurance company could successfully lower its rates by using greater leverage than private industry when negotiating with hospitals and doctors, as well as paying the employees of the public option insurance company salaries as opposed to paying based on individual medical procedures.
Michael F. Cannon, a senior fellow of the libertarian CATO Institute, has argued that the federal government can hide inefficiencies in its administration and draw away consumers from private insurance even if the government offers an inferior product. A study by the Congressional Budget Office found that profits accounted for only about 4 or 5 percent of private health insurance premiums, and Cannon argued that the lack of a profit motive reduces incentives to eliminate wasteful administrative costs.
In 2006, a new system of health insurance came into force in the Netherlands. This new system avoids the two pitfalls of adverse selection and moral hazard associated with traditional forms of health insurance by using a combination of regulation and an insurance equalization pool. Moral hazard is avoided by mandating that insurance companies provide at least one policy which meets a government set minimum standard level of coverage, and all adult residents are obliged by law to purchase this coverage from an insurance company of their choice. All insurance companies receive funds from the equalization pool to help cover the cost of this government-mandated coverage. This pool is run by a regulator which collects salary-based contributions from employers, which make up about 50% of all health care funding, and funding from the government to cover people who cannot afford health care, which makes up an additional 5%.
Medicare Advantage plans expand the health insurance options for people with Medicare. Medicare Advantage was created under the Balanced Budget Act of 1997, with the intent to better control the rapid growth in Medicare spending, as well as to provide Medicare beneficiaries more choices. But on average, Medicare Advantage plans cost 12% more than traditional Medicare. The ACA took steps to align payments to Medicare Advantage plans with the cost of traditional Medicare.
The first government responsibility is the fixing of the rate at which medical expenses should be negotiated, and it does so in two ways: The Ministry of Health directly negotiates prices of medicine with the manufacturers, based on the average price of sale observed in neighboring countries. A board of doctors and experts decides if the medicine provides a valuable enough medical benefit to be reimbursed (note that most medicine is reimbursed, including homeopathy). In parallel, the government fixes the reimbursement rate for medical services: this means that a doctor is free to charge the fee that he wishes for a consultation or an examination, but the social security system will only reimburse it at a pre-set rate. These tariffs are set annually through negotiation with doctors' representative organisations.
