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.

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.
In 2003, according to the Heartland Institute's Merrill Matthews, association group health insurance plans offered affordable health insurance to "some 6 million Americans." Matthews responded to the criticism that said that some associations work too closely with their insurance providers. He said, "You would expect the head of AARP to have a good working relationship with the CEO of Prudential, which sells policies to AARP's seniors."[83]
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).

Carrin and James have identified 1988—105 years after Bismarck's first sickness fund laws—as the date Germany achieved universal health coverage through this series of extensions to minimum benefit packages and expansions of the enrolled population. Bärnighausen and Sauerborn have quantified this long-term progressive increase in the proportion of the German population covered by public and private insurance. Their graph is reproduced below as Figure 1: German Population Enrolled in Health Insurance (%) 1885–1995.

Since people who lack health insurance are unable to obtain timely medical care, they have a 40% higher risk of death in any given year than those with health insurance, according to a study published in the American Journal of Public Health. The study estimated that in 2005 in the United States, there were 45,000 deaths associated with lack of health insurance.[14] A 2008 systematic review found consistent evidence that health insurance increased utilization of services and improved health.[15]
The remaining 45% of health care funding comes from insurance premiums paid by the public, for which companies compete on price, though the variation between the various competing insurers is only about 5%.[citation needed] However, insurance companies are free to sell additional policies to provide coverage beyond the national minimum. These policies do not receive funding from the equalization pool, but cover additional treatments, such as dental procedures and physiotherapy, which are not paid for by the mandatory policy.[citation needed]
Public insurance cover increased from 2000–2010 in part because of an aging population and an economic downturn in the latter part of the decade. Funding for Medicaid and CHIP expanded significantly under the 2010 health reform bill.[9] The proportion of individuals covered by Medicaid increased from 10.5% in 2000 to 14.5% in 2010 and 20% in 2015. The proportion covered by Medicare increased from 13.5% in 2000 to 15.9% in 2010, then decreased to 14% in 2015.[3][10]
