Beginning with 10% of blue-collar workers in 1885, mandatory insurance has expanded; in 2009, insurance was made mandatory on all citizens, with private health insurance for the self-employed or above an income threshold. As of 2016, 85% of the population is covered by the compulsory Statutory Health Insurance (SHI) (Gesetzliche Krankenversicherung or GKV), with the remainder covered by private insurance (Private Krankenversicherung or PKV) Germany's health care system was 77% government-funded and 23% privately funded as of 2004. While public health insurance contributions are based on the individual's income, private health insurance contributions are based on the individual's age and health condition.
Health insurance in the United States is any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance, or a social welfare program funded by the government. Synonyms for this usage include "health coverage", "health care coverage", and "health benefits". In a more technical sense, the term "health insurance" is used to describe any form of insurance providing protection against the costs of medical services. This usage includes private insurance and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs like Medicaid and the Children's Health Insurance Program, which both provide assistance to people who cannot afford health coverage.
In November 2017, President Trump directed "the Department of Labor to investigate ways that would "allow more small businesses to avoid many of the [Affordable Care Act's] costly requirements." Under the ACA, small-employer and individual markets had "gained important consumer protections under the ACA and state health laws — including minimum benefit levels." In a December 28, 2017 interview with the New York Times, Trump explained that, "We've created associations, millions of people are joining associations. ...That were formerly in Obamacare or didn't have insurance. Or didn't have health care. ...It could be as high as 50 percent of the people. So now you have associations, and people don't even talk about the associations. That could be half the people are going to be joining up...So now you have associations and the individual mandate. I believe that because of the individual mandate and the association".
In the late 1990s federal legislation had been proposed to "create federally-recognized Association Health Plans which was then "referred to in some bills as 'Small Business Health Plans.' The National Association of Insurance Commissioners (NAIC), which is the "standard-setting and regulatory of chief insurance regulators from all states, the District of Columbia and territories, cautioned against implementing AHPs citing "plan failures like we saw The Multiple Employer Welfare Arrangements (MEWAs) in the 1990s." "[S]mall businesses in California such as dairy farmers, car dealers, and accountants created AHPs "to buy health insurance on the premise that a bigger pool of enrollees would get them a better deal." A November 2017 article in the Los Angeles Times described how there were only 4 remaining AHPs in California. Many of the AHPs filed for bankruptcy, "sometimes in the wake of fraud." State legislators were forced to pass "sweeping changes in the 1990s" that almost made AHPs extinct.
Other managed care techniques include such elements as disease management, case management, wellness incentives, patient education, utilization management and utilization review. These techniques can be applied to both network-based benefit programs and benefit programs that are not based on a provider network. The use of managed care techniques without a provider network is sometimes described as "managed indemnity."
A 2011 study found that there were 2.1 million hospital stays for uninsured patients, accounting for 4.4% ($17.1 billion) of total aggregate inpatient hospital costs in the United States. The costs of treating the uninsured must often be absorbed by providers as charity care, passed on to the insured via cost-shifting and higher health insurance premiums, or paid by taxpayers through higher taxes.
Over time, the operations of many Blue Cross and Blue Shield operations have become more similar to those of commercial health insurance companies. However, some Blue Cross and Blue Shield plans continue to serve as insurers of last resort. Similarly, the benefits offered by Blues plans, commercial insurers, and HMOs are converging in many respects because of market pressures. One example is the convergence of preferred provider organization (PPO) plans offered by Blues and commercial insurers and the point of service plans offered by HMOs. Historically, commercial insurers, Blue Cross and Blue Shield plans, and HMOs might be subject to different regulatory oversight in a state (e.g., the Department of Insurance for insurance companies, versus the Department of Health for HMOs). Today, it is common for commercial insurance companies to have HMOs as subsidiaries, and for HMOs to have insurers as subsidiaries (the state license for an HMO is typically different from that for an insurance company). At one time the distinctions between traditional indemnity insurance, HMOs and PPOs were very clear; today, it can be difficult to distinguish between the products offered by the various types of organization operating in the market.
Shortly after his inauguration, President Clinton offered a new proposal for a universal health insurance system. Like Nixon's plan, Clinton's relied on mandates, both for individuals and for insurers, along with subsidies for people who could not afford insurance. The bill would have also created "health-purchasing alliances" to pool risk among multiple businesses and large groups of individuals. The plan was staunchly opposed by the insurance industry and employers' groups and received only mild support from liberal groups, particularly unions, which preferred a single payer system. Ultimately it failed after the Republican takeover of Congress in 1994.
In-network and out-of-network providers – some plans cover different costs from in-network, versus out-of-network, providers. In-network providers are those who agree to the health insurer’s policies and procedures and typically result in less expense to the insured. Out-of-network providers are those providers that have not yet agreed fully to the health insurer’s policies and procedures. The insurer typically cover less expense or no expense at all for out-of-network providers.
States regulate small group premium rates, typically by placing limits on the premium variation allowable between groups (rate bands). Insurers price to recover their costs over their entire book of small group business while abiding by state rating rules. Over time, the effect of initial underwriting "wears off" as the cost of a group regresses towards the mean. Recent claim experience—whether better or worse than average—is a strong predictor of future costs in the near term. But the average health status of a particular small employer group tends to regress over time towards that of an average group. The process used to price small group coverage changes when a state enacts small group reform laws.
