How Does Health Insurance Works
Health Insurance Work
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 both private insurance programs 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 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.
The share of Americans without health insurance has been cut in half since 2013. Many of the reforms instituted by the Affordable Care Act of 2010 were designed to extend health care coverage to those without it; however, high cost growth continues unabated. National health expenditures are projected to grow 4.7% per person per year from 2016 to 2025. Public healthcare spending was 29% of federal mandated spending in 1990 and 35% of it in 2000. It is also projected to be roughly half in 2025.
Enrollment and the uninsured
Gallup issued a report in July 2014 stating that the uninsured rate for adults 18 and over declined from 18% in 2013 to 13.4% by in 2014, largely because there were new coverage options and market reforms under the Affordable Care Act. Rand Corporation had similar findings.
Trends in private coverage
The proportion of non-elderly individuals with employer-sponsored cover fell from 66% in 2000 to 56% in 2010, then stabilized following the passage of the Affordable Care Act. Employees who worked part-time (less than 30 hours a week) were less likely to be offered coverage by their employer than were employees who worked full-time (21% vs. 72%).
A major trend in employer sponsored coverage has been increasing premiums, deductibles, and co-payments for medical services, and increasing the costs of using out-of-network health providers rather than in-network providers.
Trends in public coverage
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.
Status of the uninsured
The uninsured proportion was stable at 14–15% from 1990 to 2008, then rose to a peak of 18% in Q3 2013 and rapidly fell to 11% in 2015. The proportion without insurance has stabilized at 9%.
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.
Since people who lack health insurance are unable to obtain timely medical care, they have a 40% higher risk of death in any given year than those with health insurance, according to a study published in the American Journal of Public Health. The study estimated that in 2005 in the United States, there were 45,000 deaths associated with lack of health insurance. A 2008 systematic review found consistent evidence that health insurance increased utilization of services and improved health.
A study at Johns Hopkins Hospital found that heart transplant complications occurred most often amongst the uninsured, and that patients who had private health plans fared better than those covered by Medicaid or Medicare.
The Affordable Care Act of 2010 was designed primarily to extend health coverage to those without it by expanding Medicaid, creating financial incentives for employers to offer coverage, and requiring those without employer or public coverage to purchase insurance in newly created health insurance exchanges. This requirement for almost all individuals to maintain health insurance is often referred to as the “individual mandate.” The CBO has estimated that roughly 33 million who would have otherwise been uninsured will receive coverage because of the act by 2022.
Repeal of the Individual Mandate
The Tax Cuts and Jobs Act of 2017 effectively repealed the individual mandate, meaning that individuals will no longer be penalized for failing to maintain health coverage starting in 2019. The CBO projects that this change will result in four million more uninsured by 2019, 13 million more by 2027.
Main article: Health insurance coverage in the United States § Underinsured
Those who are insured may be underinsured such that they cannot afford full medical care, for example due to the exclusion of pre-existing conditions, or from high deductibles or co-payments. In 2019 Gallup found while only 11% reported being uninsured, 25% of U.S. adults said they or a family member had delayed treatment for a serious medical condition during the year because of cost, up from 12% in 2003 and 19% in 2015. For any condition, 33% reported delaying treatment, up from 24% in 2003 and 31% in 2015.
Public health care coverage
Public programs provide the primary source of coverage for most seniors and also low-income children and families who meet certain eligibility requirements. The primary public programs are Medicare, a federal social insurance program for seniors (generally persons aged 65 and over) and certain disabled individuals; Medicaid, funded jointly by the federal government and states but administered at the state level, which covers certain very low income children and their families; and CHIP, also a federal-state partnership that serves certain children and families who do not qualify for Medicaid but who cannot afford private coverage. Other public programs include military health benefits provided through TRICARE and the Veterans Health Administration and benefits provided through the Indian Health Service. Some states have additional programs for low-income individuals.
