Health Insurance: A Primer

Summary
Given the frequent introduction of legislation aimed at modifying or building on the current
health insurance system, understanding the potential impact of such proposals requires a working
knowledge of how health insurance is provided, purchased, and regulated. This report provides
background information about these topics.
People buy insurance to protect themselves against the possibility of financial loss in the future.
Health insurance provides protection against the possibility of financial loss due to high health
care expenses. Also, people do not know ahead of time exactly what their health care expenses
will be, so paying for health insurance on a regular basis helps smooth out their out-of-pocket
spending.
While health coverage continues to be mostly a private enterprise in this country, government
plays an increasingly significant role. Government has initiated and responded to dynamics in
medicine, the economy, and the workplace through legislation and public policies. One of the
most recent legislative efforts was passage of the Patient Protection and Affordable Care Act
(ACA, P.L. 111-148, as amended). ACA includes provisions to encourage the expansion of health
insurance coverage, and establish new federal health insurance standards, among other reforms.
When fully implemented, ACA’s private health insurance provisions will affect all major U.S.
health care stakeholders, including the federal and state governments, employers, insurers, health
care providers, the medical products industry, and consumers.
Individuals and families without health coverage are more likely than those with coverage to
forgo needed health care, which often leads to worse health outcomes and the need for expensive
medical treatment. Since uninsured persons are more likely to be poor than insured persons, the
uninsured are less able to afford the health care they need. Uninsurance can lead to health care
access problems for communities, such as increased problems obtaining specialty care. Taxpayers
and the nation as a whole are affected through increased taxes and health care prices to cover the
uncompensated care expenses of uninsured persons.
Americans obtain health insurance in different settings and through a variety of methods. People
may get health coverage through the private sector, or from a publicly funded program.
Consumers may purchase health insurance on their own, as part of an employee group, or through
a trade or professional association. However, approximately 50 million Americans did not have
health coverage in 2010.
Health insurance benefits are delivered and financed under different systems. The factors that
distinguish one delivery system from another are many, including how health care is financed,
how much access to providers and services is controlled, and how much authority the enrollee has
to design her/his health plan. To illustrate, managed care is characterized by predetermined
restrictions on accessing services and providers, whereas individual decision-making regarding
use of health benefits is a hallmark of consumer driven health care, such as health savings
accounts. As economic conditions change, a specific delivery system may gain or lose the interest
of affected parties.
This report will be updated periodically.

Health Insurance: A Primer

Introduction
As health insurance coverage has evolved from an uncommon benefit to a routine one,
government’s role in subsidizing and regulating that coverage also has changed. While most
insured Americans obtain health coverage through the private sector, public entities play an
increasingly significant role.
Government’s involvement in health coverage expanded dramatically over the past several
decades:
• A long-standing rule issued by the Internal Revenue Service (IRS) stated that an
employer’s contributions to employment-based health insurance are not to be
included in an employee’s gross income for tax purposes (Internal Revenue
Code, Section 106). This ruling helped spur the growth of employer-sponsored
health benefits. The IRS also stated separately that employers could deduct such
contributions as part of business expenses.
• Advances in medicine led to escalating consumer demand for newer, better
treatments. At the same time, the cost of some treatments increased, which was
especially problematic for certain groups of consumers who lacked health
coverage. This led to government efforts to assist health care consumers in
paying for medical services through social insurance programs.1
• More and more employees began to work for more than one employer over their
lifetimes. Government was called on to address a problem many workers faced:
keeping health coverage as workers moved from job to job.
Given the frequent introduction of legislation aimed at modifying or building on the current
health insurance system, understanding the potential impact of such proposals requires a working
knowledge of how health insurance is provided, purchased, and regulated. This report provides
background information about these topics.
What Is Health Insurance?
Definitions and Principles
People buy insurance to protect themselves against the possibility of financial loss in the future.
Such losses may be due to a motor vehicle collision, natural disaster, or other circumstance. For
individuals, financial losses may result from the use of health care services. Health insurance
provides protection against the possibility of financial loss due to high health care expenses. Also,
people do not know ahead of time exactly what their health care expenses will be, so paying for
health insurance on a regular basis helps smooth out their out-of-pocket spending.

1 Publicly funded health programs generally either provide funding for direct medical services or assist consumers in
paying for health care. The latter are included in a broad category of programs based on “social insurance” principles.
Social insurance refers to publicly funded insurance programs that are statutorily mandated for certain groups of
people, such as low-income individuals.

Health Insurance: A Primer

The concept underlying insurance is “risk” (i.e., the likelihood and magnitude of financial loss).
In any type of insurance arrangement, all parties seek to minimize their own risk. In health
insurance, consumers and insurers approach the management of insurance risk differently. From
the consumer’s point of view, a person (or family) buys health insurance for protection against
financial losses resulting from the future use of medical care. From the insurer’s point of view, it
employs a variety of methods to minimize the risk it takes on when providing health coverage to
consumers, to assure that it operates a profitable business.2 One method is to cover only those
expenses arising from a pre-defined set of services and items (“covered benefits”). Another
method for limiting risk is to encourage healthier people to obtain health coverage, presumably
because healthier people would not need as many medical services as sicker people, leading to
fewer claims that the insurer would have to cover.
While the methods employed by an insurer differ from those of a consumer, each has the same
goal: to minimize risk in an uncertain future. It is this uncertainty of the future and risk of
financial loss which form the context for insurance, and the strategies to make financial loss more
predictable and manageable which drive insurance arrangements.
Uneven Distribution of Health Care Expenses
In health care, a minority of consumers are responsible for a majority of expenses. According to
an analysis of national health care expenditure data, 5% of the population accounted for nearly
half of all health expenditures in 2009.3 Given the unevenness of health care spending and the
improbability of identifying all of the highest spenders before they use medical services, insurers
employ various strategies in order to minimize the risk they bear. Examples of such strategies
include denying coverage to certain insurance applicants, excluding certain benefits to treat
preexisting health conditions, and increasing premiums based on an applicant’s risk (if allowed
under law).
Risk Pool and Rate Setting
A function of insurance is to spread risk across a group of people. This is achieved in health
insurance when people contribute to a common pool (“risk pool”) an amount at least equal to the
expected cost resulting from use of covered services by the group as a whole. In this way, the
actual costs of health services used by a few people are spread over the entire group. This is the
reason why insuring larger groups is considered less risky—the more individuals participating in
a risk pool, the less likely that the serious medical experiences of one or a few persons will result
in catastrophic financial loss for the entire pool.
An insurer calculates and charges a premium in order to finance the health coverage it provides.
The premium reflects several components, including the expected cost of claims for health care
use in a year, administrative expenses associated with running the plan, and a profit margin.4 If

2 While non-profit organizations also provide health insurance in this country, such organizations nonetheless are
interested in containing expenses, even if they do not have a profit motive. One way to reduce expenses is to minimize
the amount of risk the organization bears when it issues coverage.

the insurer accurately estimates future costs and sets appropriate premium levels, then that risk
pool has reached equilibrium where premiums paid by healthy persons in the risk pool help
subsidize the higher-than-average costs of less-healthy persons in the pool.
Risk Pool Composition and Adverse Selection
As noted above, one of the ways insurers attempt to make future costs more predictable is by
spreading the risk of a few high-cost individuals across many people. But the number of people in
a risk pool is not the only significant factor. Equally as important, if not more so, is the
composition of the group.
A consumer’s decision to obtain health coverage is based on a variety of factors, such as
individual health status, estimated need for future medical care, and disposable income.
Consumers with different health conditions, as well as varying degrees of comfort towards risk-
taking, will differ on whether they consider health insurance necessary. This is a circumstance
that insurers will consider when estimating their expenses to cover future health care use. Insurers
generally will vary the premiums they charge and the health services they cover (subject to state
and federal rules) in order to attract various segments of the population. This flexibility in rate
setting and benefit determination is particularly important in a competitive insurance market
where insurers try to provide the most attractive rates to increase their market share.
However, some risk pools do attract a disproportionate share of unhealthy individuals. In part,
this is because individuals generally know more about their own health conditions than anyone
else, including an insurer. Therefore, health care consumers have an advantage over insurers in
terms of knowing the kind and amount of health services they will use, at least in the short to mid
term. This “information asymmetry” between what consumers know compared to what insurers
know gives consumers an advantage when looking for health coverage that will meet their future
demand for health care. For example, if a consumer plans on having a child within the coming
year, that consumer will look for a health plan with generous maternity benefits. Information
asymmetry is another source of uncertainty that insurers take into account when developing and
pricing insurance products.
Individuals who expect or plan for high use of health services tend to enroll in more generous
(and consequently more expensive) health plans, a phenomenon known as “adverse selection.” In
an extreme instance of adverse selection, a disproportionate share of unhealthy people make up a
risk pool and the cost for each person in the pool rises. The higher costs may encourage the
departure of healthier members from the group, and discourage the entrance of other healthy
people, since healthier people may be able to find cheaper coverage elsewhere or decide that
coverage is too costly and become uninsured. In either situation, it leaves an even less healthy
group of people in the risk pool, which again causes the cost to rise for the remaining participants.
If there is no change in this dynamic, the group may experience a “death spiral” as it suffers
substantial adverse selection leading to an increasingly expensive risk pool and possibly
dissolution of the pool altogether. Therefore, despite the consumer’s information advantage over
insurers, it does not guarantee access to affordable and adequate health coverage.

Health Insurance: A Primer

Group Market, Nongroup Market, and Medical Underwriting
Health insurance can be provided to groups of people that are drawn together by an employer or
other organization, such as a union. Such groups are generally formed for some purpose other
than obtaining insurance, like employment. When insurance is provided to a group, it is referred
to as “group coverage” or “group insurance.” In the group market, the entity that purchases health
insurance on behalf of a group (e.g., an employer) is referred to as the plan “sponsor.”
Consumers who are not associated with a group can obtain health coverage by purchasing it
directly from an insurer in the individual (or nongroup) insurance market. Insurance carriers in
the nongroup market conduct an analysis of each applicant’s insurability. An applicant usually
must provide the insurer with an extensive medical history and, while uncommon, may be asked
to undergo a medical exam or provide physical specimens. The information is used by carriers to
assess the potential medical claims for each person by comparing characteristics of the applicant
to the insurance experience of others with similar characteristics. Once such an evaluation has
been conducted, the carrier decides whether or not to provide health coverage and determines the
terms for coverage. This evaluation and determination process is referred to as “medical
underwriting.”
Medical underwriting is standard practice in the individual insurance market, though a carrier’s
ability to reject applicants or vary the terms of coverage are restricted to some degree by federal
and state requirements. In the group health insurance market, insurers forgo underwriting in the
traditional sense (i.e., reviewing each person’s demographics and medical history). Instead, an
insurer looks at the characteristics of the collective group, such as its claims history, group
demographics, and geographic location. The insurer then charges a premium based on the
analysis of the group’s characteristics. There are exceptions to this for very small groups. For
example, when a firm with only a handful of employees applies for health coverage, the insurer
may choose to review the health conditions of each person in order to establish a premium for the
entire group. Or, the insurer may charge a larger premium due to the larger risk attributed to
smaller groups, if permitted under law.5
Fully Insured vs. Self-Insured Plans
A common distinction made between types of health insurance products is whether they are fully
insured or self-insured. A fully insured health plan is one in which the plan sponsor purchases
health coverage from a state-licensed insurance carrier. The carrier assumes the risk of providing
health benefits to the sponsor’s enrolled members. In contrast, organizations who self insure (or
self fund) do not purchase health coverage from insurers. Self-insured plans refer to health
coverage that is provided directly by the organization seeking coverage for its members (e.g., a
firm providing health benefits to its employees). Such organizations set aside funds and pay for
health benefits directly. Under self insurance, the organization bears the risk for covering medical
expenses, and such benefit plans are not subject to state insurance regulations. Firms that self
fund typically contract with third-party administrators (TPAs) to handle administrative duties
such as member services, premium collection, and utilization review. TPAs do not underwrite
insurance risk.

Health Insurance: A Primer

Self-Only vs. Family Coverage
Another common distinction made in health insurance is the tier of coverage provided under an
insurance policy or health plan; that is, whether the coverage is for one person, a family, or other
groupings. Under self-only coverage, the holder of the insurance policy is the only person
insured. (Self-only coverage is also called individual coverage. Individual coverage in this sense
should not be confused with health coverage from the individual insurance market—see
discussion above.) Family coverage applies to the policyholder and his or her dependents. Other
tiers of coverage include self plus one (two adults), and self plus children.
Administrative Expenses
Costs for administrative functions encompass a wide range of operational activities.
Administrative expenses include costs associated with contracting with providers, sales and
marketing, enrollment and billing, customer service, utilization review, case management, and
other functions.
Insurance companies report administrative costs, on a per member per month (PMPM) basis, in
regulatory filings to applicable state entities. Such data indicate a relatively stable trend, with
average costs per company increasing about $3 PMPM during a two-year span. Average
administrative costs, on a PMPM basis, were $27.31 in 2007 and rose to $30.30 in 2009.6
However, while average administrative costs have been relatively consistent, there is substantial
variation across the companies observed. Specialty firms (e.g., dental only, behavioral health)
generally report below $10 PMPM in administrative costs, and companies with an emphasis on
non-group insurance often report more than $100 PMPM in such costs. Administrative expenses
have been found to vary by market segment, with non-group insurance costing the highest and
large group the lowest. This is attributable to factors such as enrollment size. While group plans
can sell to multiple individuals (for example, through an employer’s human resources
department), non-group insurance must be sold one-by-one to each person, thus increasing
marketing and sales costs.
Tax Preference
Health insurance coverage in the United States is provided through a patchwork approach that
combines private and public means for providing and paying for health insurance and health care.
One of the key pieces of this approach encouraged the growth of employment-based health
coverage via the tax code.
Section 106 of the Internal Revenue Code states that employer contributions to employment-
based health insurance are not included in workers’ gross incomes for tax purposes. This tax
preference encourages workers to sign up for (“take-up”) health coverage within the work setting.
A separate ruling by the Internal Revenue Service clarified that such employer contributions are
business expenses and, therefore, deductible from employers’ taxable income. Both parties may
benefit: employers use health insurance coverage as a means to recruit and retain workers, while

workers typically get access to more services at better rates (see discussion below). However,
economic theory suggests that workers receive reduced wages to compensate for richer benefits.
The tax exclusion of health benefits is one of the primary reasons why health insurance coverage
is provided mainly through the workplace in the United States. Nearly 55% of Americans had
employer-sponsored insurance in 2010.7
Health Insurance Regulation
Health insurance regulation addresses a wide variety of issues: the benefits that must be offered,
the individuals to whom the insurance is made available, and the responsibilities insurers have to
consumers, to name a few. One of the most contentious issues regarding health insurance
regulation is whether it is the responsibility of individual states or the federal government. This
distinction is important because federal and state laws governing health plans differ on issues
such as mandated coverage for certain benefits, consumer access to care, and patient
compensation in courts.
Primary Responsibility of the States
The regulation of insurance traditionally has been a state responsibility, as clarified by the 1945
McCarran-Ferguson Act. Individual states have established standards and regulations overseeing
the “business of insurance,” including requirements related to the finances, management, and
business practices of an insurer. For example, all states have laws that require state-licensed
insurance carriers to offer coverage for specified health services (“benefit mandates” or
“mandated benefits”). Because fully insured plans are subject to state-established requirements,
those plans must offer those mandated benefits. On the other hand, self-insured plans are not
subject to state insurance regulations so they are exempt from such requirements.
Key Federal Laws
Despite the states’ role as the primary regulators of health insurance, overlapping federal
requirements complicate regulation of the health insurance industry. Three federal laws in
particular—the Employee Retirement Income Security Act of 1974 (ERISA, P.L. 93-406), the
Health Insurance Portability and Accountability Act of 1996 (HIPAA, P.L. 104-191), and the
Patient Protection and Affordable Care Act (ACA, P.L. 111-148, as amended)—have significant
impact on how private health insurance is provided.
ERISA outlines minimum federal standards for private-sector employer-sponsored benefits.
(Public employee benefits and plans sponsored by churches are exempt from ERISA). Passed in
response to abuses in the private pension system, the Act was developed with a focus on pensions
but the law applies to a long list of “welfare benefits” including health benefits. ERISA requires
that funds be handled prudently and in the best interest of beneficiaries, participants be informed
of their rights, and there be adequate disclosure of a plan’s financial activities. It preempts state
laws that “relate to” employee benefit plans. (In other words, the federal law overrides state laws

affecting private-sector employee benefits). This portion of ERISA was designed to ensure that
plans would be subject to the same benefit laws across all states, partly in consideration of firms
that operate in multiple states. However, state laws still apply for issues which involve the
“business of insurance.” The delineation of issues attributable to the phrases “relate to” and
“business of insurance” is not clear, and has led to long-standing debates and active litigation
over the scope of ERISA preemption.8
The core motivation behind the Health Insurance Portability and Accountability Act of 1996
(HIPAA) is to address the concern that insured persons have about losing their coverage if they
switch jobs or change health plans (“portability” of health coverage). The Act’s health insurance
provisions established federal requirements on private and public employer-sponsored health
plans and insurers. It ensures the availability and renewability of coverage for certain employees
and other persons under specified circumstances. HIPAA limits the amount of time that coverage
for preexisting medical conditions can be excluded, and prohibits discrimination on the basis of
health status-related factors. The Act also includes tax provisions designed to encourage the
expansion of health coverage through several mechanisms, such as authorizing tax-advantaged
medical savings accounts and a graduated increase of the portion of premiums self-employed
persons may deduct from their federal income tax calculations. Another set of HIPAA provisions
addresses the electronic transmission of health information and the privacy of personally
identifiable medical information (administrative simplification and privacy provisions,
respectively).9
The 111th Congress passed comprehensive health reform legislation: the Patient Protection and
Affordable Care Act (ACA, P.L. 111-148, as amended). Enacted on March 23, 2010, and
subsequently amended by a number of laws (including the Health Care and Education
Affordability Reconciliation Act of 2010, P.L. 111-152), ACA includes private insurance
provisions that impose new requirements on individuals, employers, and health plans; restructures
the private health insurance market; sets minimum standards for health coverage; and provides
financial assistance to certain individuals and, in some cases, small employers. While many of the
private insurance provisions of ACA will not be effective until 2014, some provisions have
already been implemented or become effective. Examples of implemented programs include the
temporary high-risk pools for uninsured individuals with preexisting health conditions; a
reinsurance program to reimburse employers for a portion of the health insurance claims’ costs of
their 55- to 64-year-old retirees; and small business tax credits for firms with fewer than 25 full-
time equivalents that choose to offer health insurance. Examples of ACA’s insurance market
reforms that have become effective are the requirements to extend dependent coverage to children
under age 26, provide coverage for preexisting health conditions to children under age 19, and
prohibit lifetime dollar limits on essential benefits. When fully implemented, ACA’s private
health insurance provisions will affect all major U.S. health care stakeholders, including the
federal and state governments, employers, insurers, health care providers, the medical products
industry, and consumers.10

Health Insurance: A Primer

Health Insurance Premiums
An annual source of employer health benefits data found that the average annual premium for
self-only coverage was $5,429 in 2011. The average premium for a family of four was $15,073
that same year.11 These average premiums represent a 8% increase in the cost for employer-
sponsored health benefits for self-only coverage and a 9% increase for family coverage,
compared to the previous year’s average premiums. While this signals a reprieve from double-
digit increases in recent years, average premium growth rates still outpaced both wage growth
and general inflation.12
Why Is Health Insurance Considered Important?
While health insurance coverage is not necessary to obtain health care, it is a useful mechanism
for accessing services in an environment of increasingly expensive health care. As health care
costs continue to rise, more people need greater assistance with covering medical expenses.
Health insurance provides some measure of protection for consumers, especially for those who
have limited means or greater-than-average need for medical care.
Health insurance is considered important also because of the well-documented, far-reaching
consequences of uninsurance. For instance, uninsured persons are more likely to forgo needed
health care than people with health coverage.13 This includes forgoing services for preventable or
chronic conditions, which often leads to worse health outcomes. Uninsured persons also are less
likely to have a “usual source of care,” that is, a person or place identified as the source to which
the consumer usually goes for health services or medical advice (not including emergency
rooms). Having a usual source is important because people who establish ongoing relationships
with health care providers or facilities are more likely to access preventive health services and
have regular visits with a physician, compared with individuals without a usual source.14
Therefore, to the extent that health insurance coverage facilitates access to basic medical services,
people without coverage face substantial barriers in the pursuit of the health care they need. Over
a two-year span (2008-2009), over 10% of nonelderly adults with private health insurance
identified no usual source of care, compared with 54% of uninsured, nonelderly adults who
reported no usual source.15
The negative consequences of uninsurance extend beyond the persons directly involved. For
example, the Institute of Medicine found that the insurance status of parents affects the amount of
health care their children receive.16 Another study has found negative spillover effects of

uninsurance to the community at large. For instance, insured adults in communities where
uninsurance is high are less likely to have a usual source of care compared to insured adults in
low-uninsurance communities. And “a higher proportion of insured adults also reported having
more problems getting a referral to see a needed specialist in high-uninsurance communities than
in low-uninsurance communities.”17 These findings suggest there are tangible negative spillover
effects of uninsurance on the insured at the local level. In addition, many uninsured persons forgo
preventive health care and end up developing more serious conditions requiring complex,
expensive medical services. Since health coverage is positively related to income, uninsured
persons are less likely to be able to afford this level of care. In cases where patients are unable to
cover the costs associated with receiving health services, the facilities that provided those services
must take it as a financial loss (i.e., uncompensated care). These losses can be staggering. For
example, one study estimated that uninsured individuals received approximately $56 billion
worth of uncompensated care in 2008.18
Ultimately, though, the costs for caring for the uninsured are “passed down to all taxpayers and
consumers of health care in the form of higher taxes and higher prices for services and
insurance.”19 Taxpayers are affected because the federal government makes payments to
hospitals, which take into account the share of poor people treated. The assumption is that
facilities that treat a larger proportion of poor people have a greater problem with uninsurance and
uncompensated care. The federal government also provides grants to many health centers and
other facilities that serve poor communities. In addition, states and localities fund local health
programs, public hospitals, and clinics—facilities that generally serve an uninsured or medically
underserved population. Health care consumers are affected by uninsurance because in order for
physician practices and hospitals to survive financially they have to make up the losses they
sustain. Hospitals and physicians may raise rates for certain services or discontinue unprofitable
programs in order to recoup those losses, thereby affecting consumers’ pocketbooks and access to
services. Uninsurance, then, has negative health and financial consequences for uninsured
persons, their families, communities, and the nation as a whole.
Where Do People Get Health Insurance?
Americans obtain health insurance through a variety of methods and from different sources.
People may get it through the private sector, or from a publicly funded social insurance program.
Consumers may purchase health coverage on their own, as part of an employee group, or through
a trade or professional association. A small minority of employees get health insurance at no up-
front cost because their employer pays the total premium. However, approximately 50 million
Americans did not have health insurance coverage in 2010; that is, around 16.3% of the total
population was uninsured that year.20

Health Insurance: A Primer

Employer-Sponsored Insurance
Most Americans obtain health coverage through the workplace. In 2010, approximately 169
million persons had employment-based health insurance, which accounts for approximately 55%
of the total population.
Under employer-sponsored insurance (ESI), risk pools may be comprised of active workers,
dependents, and retirees. Insurers use a number of strategies to increase the likelihood that each
risk pool includes a good proportion of healthy individuals. For instance, insurers may restrict
employees’ opportunities to take-up health coverage or switch health plans by designating a
specific time frame each year for such activities (“open enrollment period”). This strategy
decreases the likelihood that people will “game” the system by taking up coverage only when
they plan on using health services (e.g., for pregnancy and childbirth), and dropping coverage
when they no longer plan to access care. Insurers also may require the employer to enroll a
certain proportion of the firm’s eligible population. Assuming that the eligible population consists
of a good percentage of healthy people, requiring a certain proportion of all eligibles to enroll
leads to an enrollee population which contains at least some healthy people. Employers also use
strategies to encourage insurance take-up by healthy people. For example, employers pay, on
average, the majority of health insurance premiums. This practice makes health coverage a more
attractive benefit, even to those workers who do not plan to use medical services on a regular
basis. By encouraging healthy workers to take-up health insurance, the employer subsidy helps to
avoid adverse selection and contributes to the stability and diversity of the risk pool.
Advantages
ESI plans retain enrollees better than the individual health insurance market. As previously
mentioned, health benefits provided at the workplace are exempt from income and employment
taxes, encouraging the growth and continuity of employer-sponsored health insurance. Large risk
pools with a good proportion of healthy enrollees tend to be more stable than small pools or those
with a higher proportion of unhealthy enrollees. Given the strategies discussed above to
discourage adverse selection, insurers assume that ESI pools—particularly large, diverse ones—
are relatively stable. Generally, this translates into less volatile costs and better premiums overall
in the group market compared to the nongroup market. Also, large ESI groups can use their size
to negotiate for better benefits and lower cost-sharing, in contrast to individual applicants in the
nongroup market. Plan sponsors negotiate and interact with insurers on behalf of all of their
insured members, unlike in the individual market where each consumer must deal with the
insurance carrier directly in order to apply for and purchase coverage. In addition, there are
economies of scale for enrollees in the group market compared to the nongroup market for
administrative functions such as sales, billing, and customer service. For these reasons, workers
and their families receive advantages from obtaining coverage through the workplace. For plan
sponsors, the main advantage is to use health benefits for recruitment and retention of workers.
This is particularly appealing in a growing economy—such as during most of the 1990s—when
there may be high demand for workers.
Disadvantages
While there are many advantages to obtaining ESI coverage, there are challenges as well. From
the vantage point of the enrollee, one of the biggest disadvantages is the general lack of
portability. Because ESI coverage is tied to the job and not the person, any change in employment
Congressional Research Service

Health Insurance: A Primer

(such as going from full-time to part-time status, or changing jobs) may alter the health care
providers or services to which the worker has access, or disrupt health coverage altogether. Also,
in firms that offer health coverage, there is a trade off made between wages and benefits. For
workers who do not take up health insurance from those firms, they end up accepting lower
wages for a set of benefits they do not use. From the perspective of the plan sponsor, an
underlying challenge is the lack of enrollee awareness of the true costs of health care. Because the
sponsor usually contributes to the cost of the premium, enrollees do not bear the full cost of
obtaining health coverage. Also, enrollees generally do not have to cover the entire cost of the
services they use, since sponsors negotiate for lower rates and better cost-sharing arrangements
from insurers. Consumers enrolled in managed care plans particularly are shielded from health
care’s true costs. Some observers contend that this lack of cost awareness gives little incentive to
consumers to utilize medical services prudently, which leads to greater use of services and more
health care spending. In addition, sponsors’ efforts to constrain their health spending—by
increasing the employee share of the premium or cost-sharing—are made even more difficult to
justify or implement. Finally, from the perspective of the federal budget, the tax exclusion of
employer-sponsored health insurance represents a lost source for Treasury funds. (The Joint
Committee on Taxation estimated the FY2011 tax exclusion for employer-paid health insurance,
health care, and long-term care insurance premiums to be $109.3 billion.)21
Large vs. Small Groups
The group health insurance market consists of insurance products designed for large and small
groups. The underlying reason for this distinction is rooted in the inverse relationship between
insurance risk and group size (i.e., the risk associated with a group grows as the size of the group
shrinks). This concept affects employers’ offers of health benefits. For instance, a very large
employer often is able to offer multiple health plan options to its members (e.g., the Federal
Employees Health Benefits Program (FEHBP)). A large business can leverage its size to get a
more comprehensive set of benefits. In contrast, small employers are less able to provide health
coverage at all because of the greater risk associated with small groups. Even when small
employers do offer coverage, the benefits are often limited. Small employers also are much less
likely to self-fund health coverage, since there is a smaller pool for spreading risk and protecting
against catastrophic loss. Furthermore, such firms generally do not have the necessary
administrative capacity to negotiate with multiple provider groups and handle all the day-to-day
operational functions. Conditions such as these prompt legislators to develop proposals for
expanding small group participation in health insurance; for example, proposals to establish
association health plans, and to open up FEHBP to small businesses.
Association health plans are just one example among the spectrum of programs and models which
bring groups of people together for the purpose of buying health insurance. These entities include
trade and professional associations that offer health coverage to their members (association-
sponsored plans), and small firms that band together to purchase coverage as a group (health
insurance purchasing cooperatives). The premise behind group purchasing arrangements is to
decrease the administrative burden on and increase the negotiating capacity of individuals and
small employers who cannot afford to offer or purchase coverage on their own.

Health Insurance: A Primer

Public Programs
While most Americans with health insurance obtain it through the private-sector, tens of millions
of people get health coverage through public programs. Below are descriptions of selected federal
and state programs which provide payments on behalf of many persons who, due to low incomes
or high health care expenses, could not afford health care otherwise.
Medicare
The Medicare program was established in 1965, and is a federal program for persons age 65 and
older and certain persons with disabilities. Medicare consists of four parts: Part A, Hospital
Insurance; Part B, Supplementary Medical Insurance; Part C, Medicare Advantage and Part D, the
prescription drug benefit. The Medicare program provides coverage for a wide range of medical
services, such as care provided in hospitals and skilled nursing facilities, hospice care, home
health care, physician services, physical and occupational therapy, outpatient prescription drug
benefits, and other services. Medicare has been so successful in covering the elderly that the
problem of uninsurance usually is described in terms of the under-65 population.22
Medicaid and the State Children’s Health Insurance Program (CHIP)
Medicaid is the main health insurance program for low-income Americans. It is a means-tested
program, and applicants must meet financial and other criteria in order to be eligible for services.
Everyone who meets the eligibility criteria is entitled to Medicaid benefits available in their state
of residence. Medicaid provides coverage for health care and long-term-care services to certain
adults (generally parents and pregnant women), children, the elderly, and persons with
disabilities. It is jointly funded by federal and state governments, and is administered by the states
within federally set guidelines. State Medicaid programs provide a comprehensive set of services,
reflecting their diverse enrollee population. These programs must provide a set of federally
specified benefits, such as hospital services (both inpatient and outpatient), physician services,
nursing home care for ages 21 and over, home health care, and certain services for children.
States may also cover additional “optional services” and beneficiaries. Some states have used
waiver authority under Medicaid to extend coverage to uninsured persons who do not meet the
program’s categorical and/or financial tests.23 ACA includes mandatory provisions that will
significantly change the current rules for eligibility, beginning in 2014.
The State Children’s Health Insurance Program was established in 1997 to allow states to cover
uninsured low-income children who are ineligible for Medicaid. In designing their programs,
states can choose among three options: expand Medicaid, create a new “separate state” insurance
program, or devise a combination of both approaches. States that choose to expand Medicaid to
CHIP eligibles must provide the full range of mandatory Medicaid benefits, as well as all optional
services specified in their state Medicaid plans. States that establish CHIP programs that are
separate from Medicaid choose one of three benefit options. All 50 states, the District of
Columbia, and five territories have established some type of CHIP program. CHIP’s eligibility

rules target uninsured children under 19 years of age whose families’ incomes are above
Medicaid eligibility levels.24
Individual Health Insurance
The individual insurance (“nongroup”) market is often referred to as a “residual” market. The
reason is because this market provides coverage to persons who cannot obtain health insurance
through the workplace and do not qualify for public programs such as Medicare, Medicaid, or
CHIP. Consequently, the enrollee population for this private health insurance market is small.
The residual nature of the nongroup market is evident in the demographic make-up of those who
purchase coverage from it. The individual market consists of many part-time workers, part-year
workers, and self-employed persons—individuals who are unlikely to have access to employer
coverage. In addition, some people use the nongroup market as a temporary source of coverage,
such as those in-between jobs or early retirees who are not yet eligible for Medicare. 25 In fact, the
near-elderly (ages 55 to 64) are disproportionately represented in this market ,26 in part due to
their relatively weak attachments to the workplace.
In general, applicants to the individual insurance market must go through robust underwriting.
Insurance carriers in most states conduct an exhaustive analysis of each applicant’s insurability.
An applicant provides her/his medical history, and may undergo a physical exam though this is
uncommon. This medical information is used by carriers to assess the insurance risk for each
person. From this assessment, insurers decide whether to offer coverage to the applicant, and
under what terms. Federal and state requirements restrict somewhat insurers’ ability to reject
applications or design coverage based on health factors and other characteristics. Nonetheless,
some applicants are rejected from the nongroup market altogether, and others who are approved
may receive limited benefits or are charged premiums that are higher than those in the group
market for similar coverage.27 Rigorous medical underwriting results in an enrollee population
that is fairly healthy28 (two out of three policyholders report that their health is excellent or very
good), thereby excluding persons with moderate to severe health problems from the private
nongroup insurance market. Some current insurer practices in the individual market will be
prohibited or curtailed once the ACA’s private market reforms are fully implemented in 2014.29

Health Insurance: A Primer

The Uninsured
Despite the multiple sources of public and private health insurance, millions of Americans are
without health coverage. In 2010, approximately 50 million people were without health insurance
coverage. For the vast majority of the uninsured, they lack coverage because they cannot access
coverage (e.g., their employer does not offer health insurance as an employment benefit) or they
cannot afford it.
Uninsurance is characterized as a problem of the under-65 population, given near-universal
coverage of seniors through Medicare. One of the most striking characteristics of persons who
lack coverage is that a significant proportion are in low-income families. For instance, among all
uninsured persons under age 65, well over half were in poor or near poor families in 2010.30
A defining characteristic of the nonelderly uninsured population is that most have ties to the paid
labor force. In 2010, “just below 80 percent of the uninsured lived in families headed by
workers.”31 While such findings may be counter-intuitive, there are multiple reasons why
employed persons and their families may lack health coverage. For example, a worker may be
offered health insurance by his/her employer, but declines it because he/she thinks it is too
expensive. An employee may work for a small firm which is less likely than a large firm to offer
health insurance as a benefit. A low-wage employee, even working full time, is less likely to be
offered health insurance at work, and less likely to be able to afford it than higher-wage workers
in the same firm. Finally, a healthy worker may be willing to take on the risk of being uninsured
and choose not to purchase insurance at all. So despite the dominance of employer-sponsored
health insurance, the dynamics of work, insurance risk, and financial resources intersect to
impede the coverage of all workers and their families.
The problem of the uninsured is an ongoing concern to many policymakers and legislators. One
persistent topic of debate is the overall number of uninsured individuals and the direction of the
uninsurance rate. These issues have generated some controversy over dueling analyses which
show slightly different (and sometimes moderately different) findings. But despite the forceful
discussions regarding trends in uninsurance, the year-to-year changes in the uninsurance rate
actually are small. For example, from 1999 to 2010, the change in the uninsurance rate from year
to year has been less than 1% (with the exception of 2008-2009).32 Nonetheless, tens of millions
of Americans were without coverage during that time period. Such circumstances beg the
questions: why does pervasive uninsurance persist (even during the robust economy of the mid-
1990s, for example), and what are the implications for legislation and public policies to expand
health coverage?
Expanding coverage is one of the primary objectives of the ACA. The Congressional Budget
Office and the Joint Committee on Taxation estimated that ACA will increase the number of
nonelderly Americans with health insurance by about 34 million by 2021. The share of lawfully

30 Persons with income under 200% of the federal poverty level accounted for nearly 59% of all nonelderly uninsured
individuals in 2010. P. Fronstin, “Sources of Health Insurance and Characteristics of the Uninsured: Analysis of the

present, nonelderly U.S. residents with insurance coverage in 2021 will be about 95%, compared
with a projected share of about 82% in the absence of the law. However, about 23 million
nonelderly U.S. residents will remain uninsured, including individuals who choose not to
purchase health insurance and are subject to the penalty for non-compliance, individuals who are
exempt from the individual mandate for religious or other reasons, and undocumented
individuals.33
How Are Private Health Benefits Delivered?
Given the complexity of the health care system overall, it is no surprise that health benefits are
delivered and financed through different arrangements. Those arrangements vary due to
numerous factors such as how health care is financed, how much access to providers and services
are controlled, and how much authority the enrollee has to design her/his health plan. While
delivery systems may share certain characteristics, general distinctions can be made based on
payment, access, and other critical variables.
Indemnity Insurance
Under indemnity insurance, the insured person decides when and from whom to seek health
services. If the services the enrollee receives are covered under his/her insurance, the enrollee or
the enrollee’s provider files a claim with the insurer. Thus, insurers make payments
retrospectively (i.e., after the health services have been rendered), up to the maximum amounts
specified for each covered service. In this model of health care delivery, the financing of health
services and the obtaining of those services are kept separate.
This bifurcated arrangement was unquestioned for a time. But as medical costs began to rise,
sometimes faster than other sectors of the national economy, many observers criticized this
delivery model as contributing to increasing expenditures. Because providers were compensated
on a fee-for-service basis, some argued that providers were not given incentives to provide
efficient health care. In fact, some critics accused health care practitioners and institutions of
providing an over-abundance of health care in order to generate greater revenue. By the early
1970s, legislators, analysts, and others expressed considerable interest in alternative models, such
as managed care models, with cost control as a key feature.
Managed Care
While managed care means different things to different people, several key characteristics set it
apart from traditional (indemnity) insurance. One of the main differences is that the service
delivery and financing functions are integrated under managed care. Managed care organizations
(MCOs) employ various techniques to control costs and manage health service use prospectively.
Among those techniques are restricting enrollee access to certain providers (“in-network”
providers); requiring primary-care-physician approval for access to specialty care
(“gatekeeping”); coordinating care for persons with certain conditions (“disease management” or
“case management”); and requiring prior authorization for routine hospital inpatient care (“pre-

certification”). MCOs may offer different types of health plans that vary in the degree to which
cost and medical decision-making is controlled. As a consequence, enrollee cost-sharing also
varies. Generally, the more tightly managed a plan is, the less the premium charged. Other
distinguishing features of the managed care approach include an emphasis on preventive health
care and implementation of quality assurance processes.
Managed care was touted as the antidote to rapidly rising health care costs. Starting with the
passage of federal legislation in the 1970s which supported the growth of managed care
(specifically in the form of health maintenance organizations (HMOs)), the number of MCOs
grew quickly. Increased market competition among these organizations led to decreases in
premiums, in order to gain market share. With high medical inflation in the 1980s and early
1990s, enrollees flocked to these less-costly managed care plans. By the mid-1990s, more insured
workers were enrolled in HMOs than any other health plan type, and health insurance premiums
had stabilized.
But in the latter half of the 1990s, a “backlash” of sorts against managed care grew.34 Some
enrollees had grown weary of provider and service restrictions. Many MCOs that had increased
market share through artificially low premiums began to raise them in order to increase revenue.35
Consumers and others accused the managed care industry of caring more about controlling costs
than providing health care. Some providers resented the role managed care played in medical
decision-making. Many enrollees began to leave HMOs. The industry responded by developing
insurance products that were less-tightly managed, but more costly. Some traditional HMOs
widened their provider networks and eliminated the gatekeeping function, while employers began
to offer plan types that were less tightly managed, such as preferred provider organizations
(PPOs).36 In fact, by the end of the 1990s, more people with work-based health coverage were
enrolled in PPOs than in HMOs.37
As the influence of managed care waned and health care costs began to rise at an increasing pace
during the late 1990s, the impact on consumers began to be felt. For example, in the employment
setting, employers absorbed the extra costs at first in order to recruit and retain workers during
the booming economy of the mid to late 1990s.38 But as the economy soured, employers began to
pass these expenses along to enrollees in the form of greater cost-sharing.39

Health Insurance: A Primer

Consumer-Driven Health Care
By the end of the 1990s, large increases in health costs again became commonplace. With the
belief by some observers that the age of managed care was over, they began to search for
alternatives. Consumer-driven (or consumer-directed) health care have been offered as one such
option.
Consumer-driven health care refers to a broad spectrum of coverage arrangements that give
incentives to consumers to control their use of health services and/or ration their own health
benefits. In the workplace, at one extreme employers may choose to provide an array of insurance
products from which workers can choose, while at the other end an employer could increase
wages but not offer any health coverage allowing workers to decide how to spend that extra
money to meet their health care needs. Within those two endpoints, the consumer-directed
approach varies in the degree to which consumers are responsible for health care decision-
making.40
For example, one example that is at the heart of discussions about consumer-driven care is the
health savings account (HSA). An HSA, in and of itself, is not a health insurance plan. Instead, it
is an investment account in which contributions earn interest tax free. Consumers, their
employers, or both may make contributions to HSAs. Consumers withdraw funds on a tax-free
basis to cover medical expenses not covered by health insurance. Unused contributions roll over
to the next year. HSAs are paired with high-deductible health plans. If the HSA funds are
exhausted and the deductible level has not been reached, the consumer is responsible for covering
that gap. Once the consumer’s spending reaches the deductible level, then coverage from the
health plan takes effect. HSAs were authorized in November 2003 under the Medicare
Prescription Drug, Improvement, and Modernization Act of 2003 (P.L. 108-173).41
While consumer-driven health care can take on many forms, the premise common to all of these
approaches is that by making enrollees more responsible for their own health care, it creates
incentives for people to use services prudently. The expectation is that greater cost-consciousness
on the part of consumers will result in lower overall health costs. In essence, the service and cost
control functions administered by MCOs and providers under managed care shifts to enrollees
under the consumer-driven health care scenario.
Proponents of consumer-directed health care assert the merit in having people take increased
responsibility for their own health care use and expenses. They predict that this approach will
lead to better-informed consumers, more appropriate use of health services, and lower overall
spending on health care. Opponents express concern that this approach does not recognize the
possible range of health conditions in an enrolled population. They argue that these plans benefit
the young and healthy who use relatively few services, and, therefore, would not need to expend a
great deal of time and energy making these health care decisions. Also, opponents point out that
the tax advantages of such insurance arrangements benefit the wealthy to a greater extent than
those less well off. In addition, opponents argue that these plans impose a greater burden on
