Provider networks can be used to reduce costs by negotiating favorable fees from providers, selecting cost effective providers, and creating financial incentives for providers to practice more efficiently.[22] A survey issued in 2009 by America's Health Insurance Plans found that patients going to out-of-network providers are sometimes charged extremely high fees.[99][100]
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.'[79] 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."[80] "[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."[81] 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.[81]
According to some experts, such as Uwe Reinhardt,[120] Sherry Glied, Megan Laugensen,[121] Michael Porter, and Elizabeth Teisberg,[122] this pricing system is highly inefficient and is a major cause of rising health care costs. Health care costs in the United States vary enormously between plans and geographical regions, even when input costs are fairly similar, and rise very quickly. Health care costs have risen faster than economic growth at least since the 1970s. Public health insurance programs typically have more bargaining power as a result of their greater size and typically pay less for medical services than private plans, leading to slower cost growth, but the overall trend in health care prices have led public programs' costs to grow at a rapid pace as well.
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.[1] 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.
