^ Bump, Jesse B. (19 October 2010). "The long road to universal health coverage. A century of lessons for development strategy" (PDF). Seattle: PATH. Retrieved 10 March 2013. 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.
Approximately 19 percent of Americans had coverage under Medicaid in 2016, and 14 percent had coverage under Medicare. These are government-run programs, as opposed to private coverage. However, the state and federal governments contract with private insurers to offer Medicaid managed care plans and Medicare Advantage plans, all of which are run by private insurers (in many cases, the same private insurers that offer employer-sponsored and individual market plans to the rest of the population).
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. 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.
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.
