Americans are required to carry medical insurance that meets federally designated minimum standards or face a tax penalty. In certain cases, taxpayers may qualify for an exemption from the penalty if they were unable to obtain insurance due to financial hardship or other situations. Two public health insurance plans, Medicare and the Children's Health Insurance Program, target older individuals and children, respectively. Medicare also serves people with certain disabilities. The program is available to anyone age 65 or older. The CHIP plan has income limits and covers babies and children up to the age of 18.
Supporters of a public plan, such as Washington Post columnist E. J. Dionne, argue that many places in the United States have monopolies in which one company, or a small set of companies, control the local market for health insurance. Economist and New York Times columnist Paul Krugman also wrote that local insurance monopolies exist in many of the smaller states, accusing those who oppose the idea of a public insurance plan as defenders of local monopolies. He also argued that traditional ideas of beneficial market competition do not apply to the insurance industry given that insurers mainly compete by risk selection, claiming that "[t]he most successful companies are those that do the best job of denying coverage to those who need it most."
The types of coverage available to small employers are similar to those offered by large firms, but small businesses do not have the same options for financing their benefit plans. In particular, self-funded health care (whereby an employer provides health or disability benefits to employees with its own funds rather than contracting an insurance company) is not a practical option for most small employers. A RAND Corporation study published in April 2008 found that the cost of health care coverage places a greater burden on small firms, as a percentage of payroll, than on larger firms. A study published by the American Enterprise Institute in August 2008 examined the effect of state benefit mandates on self-employed individuals, and found that "the larger the number of mandates in a state, the lower the probability that a self-employed person will be a significant employment generator." Beneficiary cost sharing is, on average, higher among small firms than large firms.
Health insurance is a benefit provided through a government agency, private business, or non-profit organization. To determine cost, a provider estimates collective medical expenses of a population, then divides that risk amongst the group of policy subscribers. In concept, insurers recognize that one person may incur large unexpected expenses, while another may incur none. The expense, then, is spread among a group of individuals to make health care more affordable for the common good of all. In addition, public health programs like Medicare, Medicaid, and SCHIP are federally-funded and state-run to provide additional medical coverage to those in vulnerable groups who qualify, such as seniors and those with disability.
Efforts to pass a national pool were unsuccessful for many years. With the Patient Protection and Affordable Care Act, it became easier for people with pre-existing conditions to afford regular insurance, since all insurers are fully prohibited from discriminating against or charging higher rates for any individuals based on pre-existing medical conditions. Therefore, most of the state-based pools shut down. As of 2017, some remain due to statutes which have not been updated, but they also may cover people with gaps in coverage such as undocumented immigrants or Medicare-eligible individuals under the age of 65.
Health insurance is an insurance that covers the whole or a part of the risk of a person incurring medical expenses, spreading the risk over a large number of persons. By estimating the overall risk of health care and health system expenses over the risk pool, an insurer can develop a routine finance structure, such as a monthly premium or payroll tax, to provide the money to pay for the health care benefits specified in the insurance agreement. The benefit is administered by a central organization such as a government agency, private business, or not-for-profit entity.
Health insurance in the United States is any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance, or a social welfare program funded by the government. Synonyms for this usage include "health coverage", "health care coverage", and "health benefits". In a more technical sense, the term "health insurance" is used to describe any form of insurance providing protection against the costs of medical services. This usage includes private insurance and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs like Medicaid and the Children's Health Insurance Program, which both provide assistance to people who cannot afford health coverage.
