Health insurance is a type of insurance coverage that pays for medical and surgical expenses incurred by the insured. Health insurance can reimburse the insured for expenses incurred from illness or injury, or pay the care provider directly. It is often included in employer benefit packages as a means of enticing quality employees. The cost of health insurance premiums is deductible to the payer, and the benefits received are tax-free.
Coupled with high-deductible plans are various tax-advantaged savings plans—funds (such as salary) can be placed in a savings plan, and then go to pay the out-of-pocket expenses. This approach to addressing increasing premiums is dubbed "consumer driven health care", and received a boost in 2003, when President George W. Bush signed into law the Medicare Prescription Drug, Improvement, and Modernization Act. The law created tax-deductible Health Savings Accounts (HSAs), untaxed private bank accounts for medical expenses, which can be established by those who already have health insurance. Withdrawals from HSAs are only penalized if the money is spent on non-medical items or services. Funds can be used to pay for qualified expenses, including doctor's fees, Medicare Parts A and B, and drugs, without being taxed.
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.
Public polling consistently showed majority support for a public option. A July 2009 survey by the Quinnipiac University Polling Institute found that 28% of Americans would like to purchase a public plan while 53% would prefer to have a private plan. It also stated that 69% would support its creation in the first place. Survey USA estimated that the majority of Americans (77%) feel that it is either "Quite Important" or "Extremely Important" to "give people a choice of both a public plan administered by the federal government and a private plan for their health insurance" in August 2009. A Rasmussen Reports poll taken on August 17–18 stated that 57% of Americans did not support the current health care bill being considered by Congress that did not include a public option, a change from their findings in July 2009. A NBC News/Wall Street Journal poll, conducted August 15–17, found that 47% of Americans opposed the idea of a public option and 43% expressed support. A Pew Research Center report published on October 8, 2009 stated that 55% of Americans favor a government health insurance plan to compete with private plans. The results were very similar to their polling from July, which found 52% support. An October 2009 Washington Post/ABC poll showed 57% support, a USA Today/Gallup survey described by a USA Today article on October 27 found that 50% of Americans supported a government plan proposal, and a poll from November 10 and 11 by Angus Reid Public Opinion found that 52% of Americans supported a public plan. On October 27, journalist Ray Suarez of The News Hour with Jim Lehrer noted that "public opinion researchers say the tide has been shifting over the last several weeks, and now is not spectacularly, but solidly in favor of a public option."
Some, if not most, health care providers in the United States will agree to bill the insurance company if patients are willing to sign an agreement that they will be responsible for the amount that the insurance company doesn't pay. The insurance company pays out of network providers according to "reasonable and customary" charges, which may be less than the provider's usual fee. The provider may also have a separate contract with the insurer to accept what amounts to a discounted rate or capitation to the provider's standard charges. It generally costs the patient less to use an in-network provider.
Many health insurance plans place dollar limits upon the claims the insurer will pay over the course of a plan year. Beginning September 23, 2010, PPACA phases annual dollar limits will be phased out over the next 3 years until 2014 when they will not be permitted for most plans. There is an exception to this phase out for Grandfathered Plans. Except for Grandfathered Plans, beginning September 23, 2012 annual limits can be no lower than $2 million. Except for Grandfathered Plans, beginning January 1, 2014, all annual dollar limits on coverage of essential health benefits will be prohibited.
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.
