Typically, employer-sponsored plans can include a range of plan options. From health maintenance organizations (HMOs) and preferred provider organizations (PPOs) to plans that provide additional coverage such as dental insurance, life insurance, short-term disability insurance, and long-term disability insurance, employer-sponsored health plans can be comprehensive to meet the insurance needs of employees.
The US health insurance market is highly concentrated, as leading insurers have carried out over 400 mergers from the mid-1990s to the mid-2000s (decade). In 2000, the two largest health insurers (Aetna and UnitedHealth Group) had total membership of 32 million. By 2006 the top two insurers, WellPoint (now Anthem) and UnitedHealth, had total membership of 67 million. The two companies together had more than 36% of the national market for commercial health insurance. The AMA has said that it "has long been concerned about the impact of consolidated markets on patient care." A 2007 AMA study found that in 299 of the 313 markets surveyed, one health plan accounted for at least 30% of the combined health maintenance organization (HMO)/preferred provider organization (PPO) market. In 90% of markets, the largest insurer controls at least 30% of the market, and the largest insurer controls more than 50% of the market in 54% of metropolitan areas. The US Department of Justice has recognized this percentage of market control as conferring substantial monopsony power in the relations between insurer and physicians.
Plans with much higher deductibles than traditional health plans—primarily providing coverage for catastrophic illness—have been introduced. Because of the high deductible, these provide little coverage for everyday expenses—and thus have potentially high out-of-pocket expenses—but do cover major expenses. Couple with these are various forms of savings plans.
As far as the compulsory health insurance is concerned, the insurance companies cannot set any conditions relating to age, sex or state of health for coverage. Although the level of premium can vary from one company to another, they must be identical within the same company for all insured persons of the same age group and region, regardless of sex or state of health. This does not apply to complementary insurance, where premiums are risk-based.
Most aspects of private health insurance in Australia are regulated by the Private Health Insurance Act 2007. Complaints and reporting of the private health industry is carried out by an independent government agency, the Private Health Insurance Ombudsman. The ombudsman publishes an annual report that outlines the number and nature of complaints per health fund compared to their market share 
In March 2017, the U.S. House of Representatives passed The Small Business Health Fairness Act (H.R. 1101), which established "requirements for creating a federally-certified AHP, including for certification itself, sponsors and boards of trustees, participation and coverage, nondiscrimination, contribution rates, and voluntary termination."
Individuals injured on the job while employed by private companies or state and local government agencies should contact their state workers' compensation board. The Department of Labor has several programs designed to prevent work-related injuries and illnesses. You may obtain information about these programs by visiting the Workplace Safety & Health page.
Foreseeing a long and costly political battle, many labor unions chose to campaign for employer-sponsored coverage, which they saw as a less desirable but more achievable goal, and as coverage expanded the national insurance system lost political momentum and ultimately failed to pass. Using health care and other fringe benefits to attract the best employees, private sector, white-collar employers nationwide expanded the U.S. health care system. Public sector employers followed suit in an effort to compete. Between 1940 and 1960, the total number of people enrolled in health insurance plans grew seven-fold, from 20,662,000 to 142,334,000, and by 1958, 75% of Americans had some form of health coverage.
Coinsurance: Instead of, or in addition to, paying a fixed amount up front (a co-payment), the co-insurance is a percentage of the total cost that insured person may also pay. For example, the member might have to pay 20% of the cost of a surgery over and above a co-payment, while the insurance company pays the other 80%. If there is an upper limit on coinsurance, the policy-holder could end up owing very little, or a great deal, depending on the actual costs of the services they obtain.
The purpose behind the public option was to make more affordable health insurance for uninsured citizens who are either unable to afford the rates of or are rejected by private health insurers. Supporters argued that a government insurance company could successfully lower its rates by using greater leverage than private industry when negotiating with hospitals and doctors, as well as paying the employees of the public option insurance company salaries as opposed to paying based on individual medical procedures.
Deductible: The amount that the insured must pay out-of-pocket before the health insurer pays its share. For example, policy-holders might have to pay a $500 deductible per year, before any of their health care is covered by the health insurer. It may take several doctor's visits or prescription refills before the insured person reaches the deductible and the insurance company starts to pay for care. Furthermore, most policies do not apply co-pays for doctor's visits or prescriptions against your deductible.
Generally, group health insurance plans cover the cost of medical office visits for illness and checkups, hospitalization, emergency room services, ambulance transportation, operations, physical therapy, and even prescription drugs, to provide several examples of potentially covered health care services. But, every plan is different and it behooves an employee to become familiar with the details of his or her employer's plan before the benefit is needed.
Dental insurance helps pay for the cost of necessary dental care. Few medical expense plans include coverage for dental expenses. About 97% of dental benefits in the United States is provided through separate policies from carriers—both stand-alone and medical affiliates—that specialize in this coverage. Typically, these dental plans offer comprehensive preventive benefits. However, major dental expenses, such as crowns and root canals, are just partially covered. Also, most carriers offer a lower rate if you select a plan that utilizes their Network providers. Discount dental programs are also available. These do not constitute insurance, but provide participants with access to discounted fees for dental work.
Health insurance absorbs or offsets healthcare costs associated with, but not limited to, routine health examinations, specialist referral visits, inpatient and outpatient surgery, unforeseen eventualities such as illnesses or injuries, and prescription medication. Health insurance policies are categorized as privately paid for by an individual, publicly provided as a service through Social Security, or commercially arranged by a company as part of an employee benefit package.
Conversely, an IBD/TIPP poll of 1,376 physicians showed that 45% of doctors "would consider leaving or taking early retirement" if Congress passes the health care plan wanted by the White House and Democrats. This poll also found that 65% of physicians oppose the White House and Democratic version of health reform. Statistician and polling expert Nate Silver has criticized that IBD/TIPP poll for what he calls its unusual methodology and bias and for the fact that it was incomplete when published as responses were still coming in.
Medicare Advantage plans expand the health insurance options for people with Medicare. Medicare Advantage was created under the Balanced Budget Act of 1997, with the intent to better control the rapid growth in Medicare spending, as well as to provide Medicare beneficiaries more choices. But on average, Medicare Advantage plans cost 12% more than traditional Medicare. The ACA took steps to align payments to Medicare Advantage plans with the cost of traditional Medicare.
Employer-sponsored health insurance plans dramatically expanded as a direct result of wage controls imposed by the federal government during World War II. The labor market was tight because of the increased demand for goods and decreased supply of workers during the war. Federally imposed wage and price controls prohibited manufacturers and other employers from raising wages enough to attract workers. When the War Labor Board declared that fringe benefits, such as sick leave and health insurance, did not count as wages for the purpose of wage controls, employers responded with significantly increased offers of fringe benefits, especially health care coverage, to attract workers.
