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.
The insured person has full freedom of choice among the approximately 60 recognised healthcare providers competent to treat their condition (in their region) on the understanding that the costs are covered by the insurance up to the level of the official tariff. There is freedom of choice when selecting an insurance company to which one pays a premium, usually on a monthly basis. The insured person pays the insurance premium for the basic plan up to 8% of their personal income. If a premium is higher than this, the government gives the insured person a cash subsidy to pay for any additional premium.
In March 2017, the U.S. House of Representatives passed The Small Business Health Fairness Act (H.R. 1101), which established "requirements for creating a federally-certified AHP, including for certification itself, sponsors and boards of trustees, participation and coverage, nondiscrimination, contribution rates, and voluntary termination."
