The Australian government announced in May 2008 that it proposes to increase the thresholds, to $100,000 for singles and $150,000 for families. These changes require legislative approval. A bill to change the law has been introduced but was not passed by the Senate. An amended version was passed on 16 October 2008. There have been criticisms that the changes will cause many people to drop their private health insurance, causing a further burden on the public hospital system, and a rise in premiums for those who stay with the private system. Other commentators believe the effect will be minimal.
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.
In January 2013, Representative Jan Schakowsky and 44 other U.S. House of Representatives Democrats introduced H.R. 261, the "Public Option Deficit Reduction Act", which would amend the 2010 Affordable Care Act to create a public option. The bill would set up a government-run health insurance plan with premiums 5% to 7% percent lower than private insurance, with the Congressional Budget Office estimating a reduction in the United States public debt by $104 billion over 10 years.
Private health insurance may be purchased on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. Most Americans with private health insurance receive it through an employer-sponsored program. According to the United States Census Bureau, some 60% of Americans are covered through an employer, while about 9% purchase health insurance directly. Private insurance was billed for 12.2 million inpatient hospital stays in 2011, incurring approximately 29% ($112.5 billion) of the total aggregate inpatient hospital costs in the United States.
Out-of-pocket maximum: Similar to coverage limits, except that in this case, the insured person's payment obligation ends when they reach the out-of-pocket maximum, and health insurance pays all further covered costs. Out-of-pocket maximum can be limited to a specific benefit category (such as prescription drugs) or can apply to all coverage provided during a specific benefit year.
A health maintenance organization (HMO) is a type of managed care organization (MCO) that provides a form of health care coverage that is fulfilled through hospitals, doctors, and other providers with which the HMO has a contract. The Health Maintenance Organization Act of 1973 required employers with 25 or more employees to offer federally certified HMO options. Unlike traditional indemnity insurance, an HMO covers only care rendered by those doctors and other professionals who have agreed to treat patients in accordance with the HMO's guidelines and restrictions in exchange for a steady stream of customers. Benefits are provided through a network of providers. Providers may be employees of the HMO ("staff model"), employees of a provider group that has contracted with the HMO ("group model"), or members of an independent practice association ("IPA model"). HMOs may also use a combination of these approaches ("network model").
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.
