Effective group health plan years beginning after September 23, 2010, if an employer-sponsored health plan allows employees' children to enroll in coverage, then the health plan must allow employees' adult children to enroll as well as long as the adult child is not yet age 26. Some group health insurance plans may also require that the adult child not be eligible for other group health insurance coverage, but only before 2014.[78]

The shared responsibility provision is part of the Affordable Care Act, also known as ACA or Obamacare. The goal is to ensure that all US citizens and permanent residents have access to quality health insurance. Any non-resident aliens, including international students on F, J, M and Q visas (and certain family members of students) are not subject to the individual mandate for their first 5 years in the U.S. All other J categories (teacher, trainee, work and travel, au pair, high school, etc.) are not subject to the individual mandate for 2 years (out of the past six).


Before the development of medical expense insurance, patients were expected to pay all other health care costs out of their own pockets, under what is known as the fee-for-service business model. During the middle to late 20th century, traditional disability insurance evolved into modern health insurance programs. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, and emergency health care procedures, and also most prescription drugs, but this was not always the case. The rise of private insurance was accompanied by the gradual expansion of public insurance programs for those who could not acquire coverage through the market.

As the population covered by Medicare grows, its costs are projected to rise from slightly over 3 percent of GDP to over 6 percent, contributing substantially to the federal budget deficit.[47] In 2011, Medicare was the primary payer for an estimated 15.3 million inpatient stays, representing 47.2 percent ($182.7 billion) of total aggregate inpatient hospital costs in the United States.[12] The Affordable Care Act took some steps to reduce Medicare spending, and various other proposals are circulating to reduce it further.
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."[20]
Health insurance isn’t just about access to healthcare – it’s also about protection from financial ruin. Insurance can be expensive, but lacking coverage can cost much more. No one is invincible; anybody can be injured in a car accident, or receive an unexpected diagnosis. While it’s unclear whether poor health begets financial insecurity or vice versa, the correlation between not having health insurance and financial instability is indisputable. Indeed, medical debt is the leading cause of personal bankruptcy filings among Americans.
The average rates paid for health insurance plans are inversely related to the amount of coverage they provide, with Platinum plans being the most expensive and Bronze / Catastrophic plans being the cheapest.

The National Association of Insurance Commissioners (NAIC), the National Governors' Association and "several insurance and consumer groups" opposed the AHP legislation.[80] The NAIC issued a Consumer Alert regarding AHPs, as proposed in Developing the Next Generation of Small Businesses Act of 2017. H.R. 1774.[80] Their statement said that AHP's "[t]hreaten the stability of the small group market" and provide "inadequate benefits and insufficient protection to consumers."[80] Under AHPs, "[f]ewer consumers would have their rights protected, "AHPs would also be exempt from state solvency requirements, putting consumers at serious risk of incurring medical claims that cannot be paid by their Association Health Plan."[79]


In addition to medical expense insurance, "health insurance" may also refer to insurance covering disability or long-term nursing or custodial care needs. Different health insurance provides different levels of financial protection and the scope of coverage can vary widely, with more than 40% of insured individuals reporting that their plans do not adequately meet their needs as of 2007.[2]
