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 health insurers have a significant economic impact in the US as employers - in 2004 they directly employed almost 470,000 people at an average salary of $61,409.
The US has a joint federal/state system for regulating insurance, with the federal government ceding primary responsibility to the states under the McCarran-Ferguson Act. States regulate the content of health insurance policies and often require coverage of specific types of medical services or health care providers. State mandates generally do not apply to the health plans offered by large employers, due to the preemption clause of the Employee Retirement Income Security Act.
EMPLOYER-SPONSORED
Employer-sponsored health insurance is paid for by businesses on behalf of their employees as part of an employee benefit package. Most private health coverage in the US is employment based. According to the Centers for Medicare and Medicaid Services, nearly 100% of large firms offer health insurance to their employees. The employer typically makes a substantial contribution towards the cost of coverage. In 2008 the average employee contribution was 16% of the cost of single coverage and 27% of the cost of family coverage. These percentages have been stable since 1999. Health benefits provided by employers are also tax favored. Employee contributions can be made on a pre-tax basis if the employer offers the benefits through a section 125 cafeteria plan.
Costs for employer-paid health insurance are rising rapidly: since 2001, premiums for family coverage have increased 78%, while wages have risen 19% and inflation has risen 17%, according to a 2007 study by the Kaiser Family Foundation. Employer costs have risen significantly per hour worked, and vary significantly. In particular, average employer costs for health benefits vary by firm size and occupation. The cost per hour of health benefits is generally higher for workers in higher-wage occupations, but represent a smaller percentage of payroll. The percentage of total compensation devoted to health benefits has been rising since the 1960s. Average premiums, including both the employer and employee portions, were $4,704 for single coverage and $12,680 for family coverage in 2008.
However, in a 2007 analysis, the Employee Benefit Research Institute concluded that the availability of employment-based health benefits for active workers in the US is stable. The "take-up rate," or percentage of eligible workers participating in employer-sponsored plans, is falling. The percentage of workers actually covered has fallen somewhat, but not sharply. EBRI interviewed employers for the study, and found that others might follow if a major employer discontinued health benefits. Public policy changes could also result in a reduction in employer support for employment-based health benefits.
Although much more likely to offer retiree health benefits than small firms, the percentage of large firms offering these benefits fell from 66% in 1988 to 34% in 2002.
SMALL EMPLOYER GROUP COVERAGE
According to a 2007 study, about 59% of employers at small firms (3-199 workers) in the US provide employee health insurance. The percentage of small firms offering coverage has been dropping steadily since 1999. The study notes that cost remains the main reason cited by small firms who do not offer health benefits. Small firms that are new are less likely to offer coverage than ones that have been in existence for a number of years. For example, using 2005 data for firms with fewer than 10 employees, 43% of those that had been in existence at least 20 years offered coverage, but only 24% of those that had been in existence less than 5 years did. The volatility of offer rates from year to year also appears to be higher for newer small businesses.
The types of coverage available to small employers are similar to those offered by large firms, but small businesses do not have the same options for financing their benefit plans. In particular, self-insuring the benefits (see Self-funded health care) is not a practical option for most small employers. A RAND Corporation study published in April 2008 found that the cost of health care coverage places a greater burden on small firms, as a percentage of payroll, than on larger firms. A study published by the American Enterprise Institute in August of 2008 examined the effect of state benefit mandates on self-employed individuals, and found that "the larger the number of mandates in a state, the lower the probability that a self-employed person will be a significant employment generator".
States regulate small group premium rates, typically by placing limits on the premium variation allowable between groups (rate bands). Insurers price to recover their costs over their entire book of small group business while abiding by state rating rules. Over time, the effect of initial underwriting "wears off" as the cost of a group regresses towards the mean. Recent claim experience - whether better or worse than average - is a strong predictor of future costs in the near term. But the average health status of a particular small employer group tends to regress over time towards that of an average group. The process used to price small group coverage changes when a state enacts small group reform laws.
Insurance brokers play a significant role in helping small employers find health insurance, particularly in more competitive markets. Average small group commissions range from 2 percent to 8 percent of premiums. Brokers provide services beyond insurance sales, such as assisting with employee enrollment and helping to resolve benefits issues.
FEDERAL EMPLOYEES HEALTH BENEFIT PLAN (FEHBP)
In addition to such public plans as Medicare and Medicaid, the federal government also sponsors a health benefit plan for federal employees - the Federal Employees Health Benefits Program (FEHBP). FEHBP provides health benefits to full-time civilian employees. Active-duty service members, retired service members and their dependents are covered through the Department of Defense Military Health System (MHS). FEHBP is managed by the federal Office of Personnel Management.
"PORTABILITY" OF GROUP COVERAGE
Two federal laws address the ability of individuals with employment-based health insurance coverage to maintain coverage.
The Consolidated Omnibus Budget Reconciliation Act of 1985 (COBRA) enables certain individuals with employer-sponsored coverage to extend their coverage if certain "qualifying events" would otherwise cause them to lose it. Employers may require COBRA-qualified individuals to pay the full cost of coverage, and coverage cannot be extended indefinitely. COBRA only applies to firms with 20 or more employees, although some states also have "mini-COBRA" laws that apply to small employers.
The Health Insurance Portability and Accountability Act of 1996 (HIPAA) provides for forms of both "group-to-group" and "group-to-individual" portability. When an individual moves from one employer's benefit plan to another's, the new plan must count coverage under the old plan against any waiting period for pre-existing conditions, as long as there is not a break in coverage of more than 63 days between the two plans. When certain qualified individuals lose group coverage altogether, they must be guaranteed access to some form of individual coverage. To qualify, they must have at least 18 months of prior continuous coverage. The details of access and the price of coverage are determined on a state-by-state basis.
INDIVIDUALLY PURCHASED
Policies of health insurance obtained by individuals not otherwise covered under policies or programs elsewhere classified. Generally major medical, short-term medical, and student policies. According to the US Census Bureau, about 9% of Americans are covered under health insurance purchased directly. The range of products available is similar to those provided through employers. However, average out-of-pocket spending is higher in the individual market, with higher deductibles, co-payments and other cost-sharing provisions. Major medical is the most commonly purchased form of individual health insurance.
In the individual market, the consumer pays the entire premium without benefit of an employer contribution. While self-employed individuals receive a tax deduction for their health insurance and can buy health insurance with additional tax benefits, most consumers in the individual market do not receive any tax benefit.
Premiums vary significantly by age. In states that allow individual medical plan underwriting, premiums also vary by health status. For individuals who pass individual medical plan underwriting where it is used, the average premiums they pay are lower than the average paid for employer-sponsored coverage (this comparison is based on the entire premium for employer-sponsored coverage, including both the employee and employer contributions). Factors that may be contributing to this include: differences in age; less generous coverage in the individual market (higher beneficiary cost sharing); and a tendency for individual consumers to only buy benefits that they expect to need and use while group coverage may provide some benefits that most beneficiaries do not use. Individual policyholders are also more likely to report being in excellent health than are people covered by employer-sponsored health insurance, which may be a contributing factor. Premiums in the individual market rose less rapidly over the period 2002 through 2005 than did out-of-pocket premiums in the employer-sponsored market (17.8% versus 34.4%). The increase was larger for family policies than for single policies (25.3% for family policies; the increase for single policies was not statistically significant). Note that these comparisons did not adjust for changes in benefit levels.
Research confirms that consumers in the individual health insurance market are sensitive to price. Estimates of the demand elasticity in this market vary, but generally fall in the range of -0.3 to -0.1. It appears that price sensitivity varies among population subgroups and is generally higher for younger individuals and lower income individuals. One study found that among individuals who lack other sources of health coverage, the percentage purchasing individual insurance increases steadily with income. However, even among those with incomes four times the federal poverty level, only about a fourth buy individual coverage. The self-employed, who can tax-deduct their premiums, are more likely to purchase than other individuals. The researchers concluded that affordability appears to be a key barrier to coverage in this market, and that any premium subsidies would likely have to be substantial to be effective. The researchers note that other factors such as health status and the complexity of the market can also affect the purchase of individual health insurance, but conclude that they are unlikely to be the primary drivers of low coverage rates.
Many states allow medical underwriting of applicants for individually purchased health insurance. An estimated 5 million of those without health insurance are considered "uninsurable" because of pre-existing conditions. A number of proposals have been advanced to limit the effect of underwriting on consumers and improve access to coverage. Each has its own advantages and limitations. One study published in 2008 found that people of average health are least likely to become uninsured if they have large group health coverage, more likely to become uninsured if they have small group coverage, and most likely to become uninsured if they have individual health insurance. But, "for people in poor or fair health, the chances of losing coverage are much greater for people who had small-group insurance than for those who had individual insurance". The authors attribute these results to the combination in the individual market of high costs and guaranteed renewability of coverage. Individual coverage costs more if it is purchased after a person becomes unhealthy, but "provides better protection (compared to group insurance) against high premiums for already individually insured people who become high risk." Healthy individuals are more likely to drop individual coverage than less-expensive, subsidized employment-based coverage, but group coverage leaves them "more vulnerable to dropping or losing any and all coverage than does individual insurance" if they become seriously ill.
In August 2008 the Hartford Courant reported that competition was increasing in the individual health insurance market, with more insurers entering the market, an increased variety of products, and a broader spread of prices.
Individual health insurance is primarily regulated at the state level, consistent with the McCarran-Ferguson Act. Model acts and regulations promulgated by the National Association of Insurance Commissioners (NAIC) provide some degree of uniformity state to state. These models do not have the force of law and have no effect unless they are adopted by a state. They are, however, used as guides by most states, and some states adopt them with little or no change.
The primary NAIC models affecting the individual health insurance market are:
- Uniform Individual Accident and Sickness Policy Provision Law (UPPL)
- Accident and Sickness Insurance Minimum Standards Model Act
- Advertisements of Accident and Sickness Insurance Model Regulation
- The Unfair Trade Practices Act
All of these models have been implemented in one form or another by most states.
Federal laws affecting individual health insurance include:
TYPES OF MEDICAL INSURANCE
TRADITIONAL INDEMNITY OR FEE-FOR-SERVICE
Commercial insurance companies began offering accident and sickness insurance (disability insurance) as early as the mid-1800s. Hospital and medical expense policies were introduced during the first half of the 20th century. The first group medical plan was purchased from The Equitable Life Assurance Society of the United States by the General Tire & Rubber Company in 1934.
Early hospital and medical plans offered by insurance companies paid either a fixed amount for specific diseases or medical procedures (schedule benefits) or a percentage of the provider's fee. The relationship between the patient and the medical provider was not changed. The patient received medical care and was responsible for paying the provider. If the service was covered by the policy, the insurance company was responsible for reimbursing or indemnifying the patient based on the provisions of the insurance contract ("reimbursement benefits"). Health insurance plans that are not based on a network of contracted providers, or that base payments on a percentage of provider charges, are still described as indemnity or fee-for-service plans.
BLUE CROSS & BLUE SHIELD PLANS
During the 1920s, individual hospitals began offering services to individuals on a pre-paid basis. The first group pre-payment plan was created at the Baylor University Hospital in Dallas, Texas. This concept became popular among hospitals during the Depression, when they were facing declining revenues. The Baylor plan was a forerunner of later Blue Cross plans. Physician associations began offering pre-paid surgical/medical benefits in the late 1930s Blue Shield plans. Blue Cross and Blue Shield plans were non-profit organizations sponsored by local hospitals (Blue Cross) or physician groups (Blue Shield). As originally structured, Blue Cross and Blue Shield plans provided benefits in the form of services rendered by participating hospitals and physicians ("service benefits") rather than reimbursements or payments to the policyholder.
HEALTH MAINTENANCE ORGANIZATIONS
The Ross-Loos Clinic, founded in Los Angeles in 1929, is generally considered to have been the first health maintenance organization (HMO).Henry J. Kaiser organized hospitals and clinics to provide pre-paid health benefits to his shipyard workers during World War II. This became the basis for Kaiser Permanente HMO. Most early HMOs were non-profit organizations. The development of HMOs was encouraged by the passage of the Health Maintenance Organization Act of 1973. 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").
MANAGED CARE
The term Managed care is used to describe a variety of techniques intended to reduce the cost of health benefits and improve the quality of care. It is also used to describe organizations that use these techniques ("managed care organization"). Many of these techniques were pioneered by HMOs, but they are now used in a wide variety of private health insurance programs. Through the 1990s, managed care grew from about 25% US employees with employer-sponsored coverage to the vast majority.

Network-based managed care
Many managed care programs are based on a panel or network of contracted health care providers.
Such programs typically include
- A set of selected providers that furnish a comprehensive array of health care services to enrollees.
- Explicit standards for selecting providers.
- Formal utilization review and quality improvement programs.
- An emphasis on preventive care.
- Financial incentives to encourage enrollees to use care efficiently.
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.
Network-based plans may be either closed or open. With a closed network, enrollees' expenses are generally only covered when they go to network providers. Only limited services are covered outside the network - typically only emergency and out-of-area care. Most traditional HMOs were closed network plans. Open network plans provide some coverage when an enrollee uses non-network provider, generally at a lower benefit level to encourage the use of network providers. Most preferred provider organization (PPO) plans are open-network (those that are not are often described as exclusive provider organizations, or EPOs), as are point of service (POS) plans.
The terms "open panel" and "closed panel" are sometimes used to describe which health care providers in a community have the opportunity to participate in a plan. In a "closed panel" HMO, the network providers are either HMO employees (staff model) or members of large group practices with which the HMO has a contract. In an "open panel" plan the HMO or PPO contracts with independent practitioners, opening participation in the network to any provider in the community that meets the plan's credential requirements and is willing to accept the terms of the plan's contract.
Other managed care techniques
Other managed care techniques include such elements as disease management, case management, wellness incentives, patient education, utilization management and utilization review. These techniques can be applied to both network-based benefit programs and benefit programs that are not based on a provider network. The use of managed care techniques without a provider network is sometimes described as "managed indemnity".
BLURRING LINES
Over time, the operations of many Blue Cross and Blue Shield operations have become more similar to those of commercial health insurance companies. However, some Blue Cross and Blue Shield plans continue to serve as insurers of last resort. Similarly, the benefits offered by Blues plans, commercial insurers, and HMOs are converging in many respects due to market pressures. One example is the convergence of preferred provider organization (PPO) plans offered by Blues and commercial insurers and the point of service plans (POS) offered by HMOs. Historically, commercial insurers, Blue Cross and Blue Shield plans, and HMOs might be subject to different regulatory oversight in a state (e.g., the Department of Insurance for insurance companies, versus the Department of Health for HMOs). Today, it is common for commercial insurance companies to have HMOs as subsidiaries, and for HMOs to have insurers as subsidiaries (the state license for an HMO is typically different from that for an insurance company). At one time the distinctions between traditional indemnity insurance, HMOs and PPOs were very clear; today, it can be difficult to distinguish between the products offered by the various types of organization operating in the market.
The blurring of distinctions between the different types of health care coverage can be seen in the history of the industry's trade associations. The two primary HMO trade associations were the Group Health Association of America and the American Managed Care and Review Association. After merging, they were known as American Association of Health Plans (AAHP). The primary trade association for commercial health insurers was the Health Insurance Association of America (HIAA). These two have now merged, and are known as America’s Health Insurance Plans (AHIP).
NEW TYPES OF MEDICAL PLANS
One approach to addressing increasing premiums, dubbed "consumer driven health care", 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). An HSA is an untaxed private bank account; withdrawals are only penalized if the money is spent on non-medical items or services. Consumers wishing to deposit pre-tax funds in an HSA must be enrolled in a high-deductible insurance plan with a number of restrictions on benefit design; in 2007, qualifying plans must have a minimum deductible of US$1,050. HSAs enable healthier individuals to pay less for insurance and bank money for their own future health care expenses.[59] HSAs are one form of tax-preferenced health care spending account. Others include Archer Medical Savings Accounts (MSAs), which have been superseded by the new HSAs (although existing MSAs are grandfathered), Flexible Spending Arrangements (FSAs) and Health Reimbursement Accounts (HRAs). HSAs, FSAs and HRAs are most commonly used as part of an employee health benefit package.
Limited Medical Benefit Plans pay for routine care and do not pay for catastrophic care. As such, they do not provide equivalent financial security to a major medical plan. Annual benefit limits can be as low as $2,000. Lifetime maximums can be very low as well.
One option that is becoming more popular is the discount medical card. These cards are not insurance policies, but provide access to discounts from participating health care providers. While some offer a degree of value, there are serious potential drawbacks for the consumer. |
