Health insurance absorbs or offsets healthcare costs associated with, but not limited to, routine health examinations, specialist referral visits, inpatient and outpatient surgery, unforeseen eventualities such as illnesses or injuries, and prescription medication. Health insurance policies are categorized as privately paid for by an individual, publicly provided as a service through Social Security, or commercially arranged by a company as part of an employee benefit package.
In the late 1990s and early 2000s, health advocacy companies began to appear to help patients deal with the complexities of the healthcare system. The complexity of the healthcare system has resulted in a variety of problems for the American public. A study found that 62 percent of persons declaring bankruptcy in 2007 had unpaid medical expenses of $1000 or more, and in 92% of these cases the medical debts exceeded $5000. Nearly 80 percent who filed for bankruptcy had health insurance. The Medicare and Medicaid programs were estimated to soon account for 50 percent of all national health spending. These factors and many others fueled interest in an overhaul of the health care system in the United States. In 2010 President Obama signed into law the Patient Protection and Affordable Care Act. This Act includes an 'individual mandate' that every American must have medical insurance (or pay a fine). Health policy experts such as David Cutler and Jonathan Gruber, as well as the American medical insurance lobby group America's Health Insurance Plans, argued this provision was required in order to provide "guaranteed issue" and a "community rating," which address unpopular features of America's health insurance system such as premium weightings, exclusions for pre-existing conditions, and the pre-screening of insurance applicants. During 26–28 March, the Supreme Court heard arguments regarding the validity of the Act. The Patient Protection and Affordable Care Act was determined to be constitutional on 28 June 2012. The Supreme Court determined that Congress had the authority to apply the individual mandate within its taxing powers.
Most provider markets (especially hospitals) are also highly concentrated—roughly 80%, according to criteria established by the FTC and Department of Justice—so insurers usually have little choice about which providers to include in their networks, and consequently little leverage to control the prices they pay. Large insurers frequently negotiate most-favored nation clauses with providers, agreeing to raise rates significantly while guaranteeing that providers will charge other insurers higher rates.
All U.S. citizens living in the United States are subject to the individual shared responsibility provision as are all permanent residents and all foreign nationals who are in the United States long enough during a calendar year to qualify as resident aliens for tax purposes. This category includes nonresident aliens who meet certain presence requirements and elect to be treated as resident aliens. For more information see Pub. 519.

Many health insurance plans place dollar limits upon the claims the insurer will pay over the course of a plan year. Beginning September 23, 2010, PPACA phases annual dollar limits will be phased out over the next 3 years until 2014 when they will not be permitted for most plans. There is an exception to this phase out for Grandfathered Plans. Except for Grandfathered Plans, beginning September 23, 2012 annual limits can be no lower than $2 million. Except for Grandfathered Plans, beginning January 1, 2014, all annual dollar limits on coverage of essential health benefits will be prohibited.

Social Science & Medicine. 54 (10): 1559–87. doi:10.1016/S0277-9536(01)00137-X. PMID 12061488. Retrieved 10 March 2013. As Germany has the world's oldest SHI [social health insurance] system, it naturally lends itself to historical analyses.
The share of Americans without health insurance has been cut in half since 2013. Many of the reforms instituted by the Affordable Care Act of 2010 were designed to extend health care coverage to those without it; however, high cost growth continues unabated. National health expenditures are projected to grow 4.7% per person per year from 2016 to 2025. Public healthcare spending was 29% of federal mandated spending in 1990 and 35% of it in 2000. It is also projected to be roughly half in 2025.
