Having health insurance is important for several reasons. Uninsured people receive less medical care and less timely care, they have worse health outcomes, and lack of insurance is a fiscal burden for them and their families. Moreover, the benefits of expanding coverage outweigh the costs for added services. Safety-net care from hospitals and clinics improves access to care but does not fully substitute for health insurance. These findings are supported by much research, although some cautions are appropriate in using these results.
Employer-sponsored health insurance plans dramatically expanded as a direct result of wage controls imposed by the federal government during World War II.[20] The labor market was tight because of the increased demand for goods and decreased supply of workers during the war. Federally imposed wage and price controls prohibited manufacturers and other employers from raising wages enough to attract workers. When the War Labor Board declared that fringe benefits, such as sick leave and health insurance, did not count as wages for the purpose of wage controls, employers responded with significantly increased offers of fringe benefits, especially health care coverage, to attract workers.[20]
The proportion of non-elderly individuals with employer-sponsored cover fell from 66% in 2000 to 56% in 2010, then stabilized following the passage of the Affordable Care Act. Employees who worked part-time (less than 30 hours a week) were less likely to be offered coverage by their employer than were employees who worked full-time (21% vs. 72%).[7]

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.[31][32] Therefore, most of the state-based pools shut down.[33] 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[33] or Medicare-eligible individuals under the age of 65.[33]
Health insurance primarily protects individuals from the prohibitively high costs of surgical procedures, inpatient hospital care, and emergency attention. Though health insurance itself can become costly for a family, it is only a small fraction of the potential costs associated with unforeseen illnesses and emergencies (for example, the diagnosis and treatment of cancer or a heart attack).
Premiums, or the cost of the medical coverage, are based on some factors including country of origin, age, medical history, etc. It is advised to have more comprehensive insurance for US medical coverage because it can cost a lot, but the costs of not having it can be much higher. For example, the tests and scans doctors often run are costly and typically not covered by budget medical insurance plans.
Both before and after passage in the House, significant controversy surrounded the Stupak–Pitts Amendment, added to the bill to prohibit coverage of abortions – with limited exceptions – in the public option or in any of the health insurance exchange's private plans sold to customers receiving federal subsidies. In mid-November, it was reported that 40 House Democrats would not support a final bill containing the Amendment's provisions.[36] The Amendment was abandoned after a deal was struck between Representative Bart Stupak and his voting bloc would vote for the bill as written in exchange for the signing of Executive Order 13535.
