Individual Insurance: How Much Financial
Protection Does It Provide?
A $1,000 tax credit should
be more than adequate to buy individual
coverage for healthy, young, single males,
but it would not even come close for their middle-aged peers.

ABSTRACT:
This paper examines the comparative financial protection provided by individual
and group health insurance. Data sources include two national surveys of employer-based
health plans and e-health insurance listings for individual coverage on the
World Wide Web. Data on the use and cost of services are from the National Medical
Expenditure Survey (NMES), a national household survey of Americans. We estimate
that individual insurance pays on average 63 percent of the health care bill,
whereas group health insurance pays 75 percent. Deductibles are much higher
in individual insurance, and covered benefits are more meager. At 200 percent
of poverty, the top 25 percent of health care users with individual coverage
would spend 11 percent of their income for out-of-pocket health care expenses,
as opposed to 6 percent for persons with group coverage.
For more than five decades group health insurance has been the leading form
of private health coverage for Americans under age sixty-five. In 1999 approximately
154 million workers and their dependents, as well as nearly four million early
retirees, received their coverage from their employer or former employer.1
The long-term decline of employer-based insurance has thrust individual insurance,
long viewed by the insurance industry as the "residual market," onto
center stage.2 From 1987 to 1993 the percentage
of Americans under age sixty-five covered by employer-based insurance fell from
69.2 percent to 63.5 percent. The vibrant economy of the 1990s added more than
twenty million new jobs in six years, but the percentage of the population under
age sixty-five with employer coverage increased only slightly, to 65.8 percent
in 1999.3 In the spirit of incremental reform,
Congress is considering legislation to extend a tax credit to persons who purchase
individual health insurance.4 The Bush administration
now proposes a $1,000 tax credit for individuals and a $3,000 tax credit for
families.5
What is the structure of this individual insurance market, which the Bush administration
and some in Congress would grow through the use of tax credits? Sixteen million
Americans purchased individual health insurance in 1999-approximately 7 percent
of the total number of nonelderly Americans holding private policies.6
Americans from different walks of life buy individual coverage: the self-employed;
workers whose employer does not offer health insurance coverage; persons who
are not in the workforce; early retirees who are not yet eligible for Medicare;
and persons who have exhausted their continuation (Consolidated Omnibus Budget
Reconciliation Act, or COBRA) coverage. Individual insurance is most commonly
purchased in the Great Plains and Mountain states, where in some states more
than 10 percent of the nonelderly population owns individual insurance policies.
Nearly 20 percent of self-employed persons and 17 percent of farm workers are
covered by an individual policy. Persons ages sixty to sixty-four are nearly
three times as likely to be covered by individual health insurance as are those
ages twenty to twenty-nine.7
Unlike insurance for large employer groups, in most states individual insurance
companies review the insurability of each applicant case by case. Not only is
a medical history likely to be required, but applicants also are often asked
to undergo a physical exam and provide blood, urine, and saliva samples to assess
their likely medical claims expenses. Because individual insurance is subject
to vigorous medical underwriting, the persons it covers tend to be in good health.
Nearly three-fourths of the individually insured report being in very good or
excellent health, and only 6 percent report being in fair or poor health.8
The costs of administering individual insurance greatly exceed those associated
with employer-based health insurance. Fees paid to insurance agents often constitute
10-15 percent of the premium dollar. Whereas administrative expenses consume
about 25-40 percent of each premium dollar for individual insurance, they account
for about 10 percent of each premium dollar among large employer groups and
15-25 percent in the small-group market.9
Recent studies have advanced public knowledge about the workings of the market
for individual health insurance. The Journal of Health Politics, Policy and
Law published an issue in 2000 dedicated solely to this market.10
Other studies have increased understanding of this market through the advent
of electronic health insurance products found on the World Wide Web. These Web
sites provide consumers with detailed descriptions of individual insurance products
available at ZIP codes throughout the United States and with quotes on the cost
of single and family coverage for persons in excellent and less-than-excellent
health.11 Still other studies explore aspects
of the individual market, such as underwriting practices and the extent of disability
and chronic illness.12
Under several simplifying assumptions, this paper examines the degree of financial
protection that individual insurance provides to persons who pass its underwriting
screens. We compare the financial protection, generally measured as actuarial
value-the percentage of the medical bill paid by insurance-for individual health
insurance with that for employer-sponsored plans. We estimate expected out-of-pocket
spending for persons holding group and individual insurance who are heavy and
light users of medical care.
To our knowledge, this paper provides the first analysis of the comparative
financial protection afforded by individual and group health insurance since
earlier analysis of the 1987 National Medical Expenditure Survey (NMES).13
We also believe that the paper provides the first comparative analysis about
the range of coverage options, prices, and financial protection provided by
indemnity, health maintenance organization (HMO), preferred provider organization
(PPO), and point-of- service (POS) plans in the individual market.
Data And Methods
Data.
For this study we used three main sources of data (or groups of databases):
one database captured data on individual insurance plans in ten states; two
national surveys provided data on group health insurance plans from national
surveys of employers; and another database provided data on use of services
from a national household sample of Americans with either individual or group
coverage.
Individual insurance data. In August 2000 our study team at the Health
Research and Educational Trust (HRET) used Web sites such as eHealthInsurance.com
and QuoteSmith.com to collect data on the provisions of health insurance plans
in two ZIP codes in each of ten states. The ten states selected (Colorado, Florida,
Minnesota, New Mexico, New York, North Dakota, Oklahoma, Oregon, Vermont, and
Washington) were the same states used in an earlier Robert Wood Johnson Foundation
(RWJF) survey that examined the impact of state insurance reforms.14
Within each state, we selected the most urban ZIP code and randomly selected
one rural ZIP code. Using a table of random numbers, we randomly selected five
individual health plans within each ZIP code. If there was a choice of HMO,
PPO, POs, and fee-for-service (FFS) plans, we selected at least one of each
type of available plan. Our total sample included 103 different individual insurance
products.
For each plan, we collected data on the "standard" monthly premium
for a twenty- seven-year-old male, a twenty-seven-year-old female, a fifty-five-year-old
male, and a fifty- five-year-old female.15 We
collected as much data as was offered on the Web sites about the benefits and
cost sharing for each insurance product. Key variables included deductibles,
out-of-pocket limits, copayments and co-insurance, and covered benefits for
selected services.
Because no data are available on enrollment in each of the plans in our sample,
we estimated plan enrollment as follows. Data from the 1998-2000 Current Population
Survey (CPS) provided statistics on the number of persons in the state covered
by individual health insurance.16 We applied national
estimates of the percentage of the individually insured rural and metropolitan
population to estimate the number of individually insured persons in each of
the ten states residing in rural and urban areas. We assumed that each plan
in our sample from rural and from urban areas in each state had equal enrollments.
Group health insurance data. One of our data sources was the 1997 RWJF
Employer Health Insurance Survey, a national survey of 21,545 private employers
with at least one worker. Using computer-assisted telephone interviews, interviewers
collected data from the person in the establishment who was most knowledgeable
about health benefits. The response rate for the survey was 60 percent. The
RWJF survey uses employee-based plan statistical weights, which allows one to
generalize about employees' out-of-pocket expenses for each health plan offered
by employers included in the sample.
The RWJF survey collected detailed information about benefits for each plan
offered by the employer at the establishment site. This included data on deductibles,
coinsurance, copayments, and out-of-pocket spending limits for hospital and
physician services, as well as cost-sharing requirements for prescription drugs
and mental health services.17 In our analysis
we used data matched to the ten states in the individual insurance sample.
To compare premiums and benefits in the individual and group insurance markets
for the same year (2000) and in the same ten states, we used the 2000 Henry
J. Kaiser Family Foundation/HRET annual survey of employers. This national survey
included 1,887 randomly selected public and private employers with three or
more workers. From previous analysis we have determined that there was little
change in covered benefits and patient cost sharing for employer-based plans
over the years 1997-2000.18 Hence, we believe
that actuarial estimates from the 1997 RWJF survey are consistent with Kaiser/HRET
data on benefits in 2000.
Data on household expenditures. We used data from the 1987 NMES for persons
with employer-based and individual health insurance to generate data on health
care spending and use of services in households headed by persons under age
sixty-five.19 NMES is a comprehensive national
survey of 15,000 households, including 36,000 individuals, conducted by the
Agency for Healthcare Research and Quality (AHRQ). Using the National Health
Accounts, Actuarial Research Corporation updated the NMES data to account for
inflation. We generated different distributions for families enrolled in HMO,
PPO/POs, and indemnity plans to account for different utilization patterns for
different types of plans and for different in- and out-of-network cost-sharing
requirements for PPO and POs plans.
Calculating actuarial values.
Using data from NMES, Actuarial Research Corporation simulated the percentage
of incurred medical expenses each health plan would pay for the relevant sample
of NMES households. Only households with individual insurance coverage were
used to calculate the actuarial values for each individual insurance plan; likewise,
only households with group coverage were used to calculate actuarial values
for each group plan.
For each individual and group plan, we calculated the following actuarial values:
(1) the average percentage of the medical bill paid by all users of health care
services; (2) the corresponding percentage of the bill paid by households with
below-median spending; (3) the percentage paid by households with spending above
the median; and (4) the percentage paid by the top 25 percent of users.
Actuarial values are weighted by expenditures. Hence, a plan with an actuarial
value of 0.70 would pay 70 percent of the incurred medical expenses of the individual
insurance population. It does not mean that insurance would pay 70 percent of
medical expenses of a typical family. In employer-sponsored health plans, 5
percent of the population incurs 52 percent of expenditures.20
We made an adjustment for use of preexisting condition clauses in individual
insurance plans. Based on data from the 1996 Medical Expenditure Panel Survey
(MEPS), we assumed that approximately 80 percent of individuals would not be
subject to preexisting condition clauses because they were covered by a former
employer or another insurer.21 For those persons
subject to such clauses, their claims expenses would likely decrease 20 percent
during the first year of coverage.22 Thus, in
total, the actuarial value for individual insurance plans was reduced by 4 percent.
Analysis.
This study compares the performance of individual and group insurance. In some
cases, we contrast the performance of individual FFS, PPO/POs, and HMO plans
with their group-coverage counterparts, and we test whether individual statistics
on FFS, PPO/POs, and HMO plans are significantly different from the overall
individual insurance mean. We have combined PPO and POs plans into one category
because it was impossible to determine the plan type from the data on the e-health
insurance Web sites.23 In comparing sample means,
we use t-tests to determine if differences in sample means are statistically
significant at the .05 alpha level.
Limitations of study methods.
The lack of information on enrollment in each individual insurance plan is the
main limitation of our study. Unfortunately, not even state insurance departments
possess information on the numbers of persons purchasing individual products.
The absence of such information compelled us to take a "second-best approach,"
in which we assumed that within a geographic area, equal numbers of persons
purchased each plan. If persons actually purchase higher-cost plans with a higher
actuarial value, the study results would underestimate the actuarial value of
individual plans and their cost. If people tend to purchase lower- cost plans,
actuarial values and costs are overestimated. In contrast, data on group plans
reflect actual numbers of persons enrolled in each plan. Given this limitation,
readers should regard estimates for the individual insurance market as simulated
extrapolations. The paper depicts the actual range of plan coverage, but the
exact location of central tendency is uncertain.
A second study limitation is the use of 1987 utilization data (adjusted according
to plan- type enrollments) in calculating actuarial values. Since 1987 inpatient
hospital use has declined, inpatient mental health services constitute a smaller
percentage of spending, and prescription drugs account for a growing portion
of spending. Many individual insurance plans do not cover outpatient prescription
drugs, whereas inpatient hospital expenses are virtually always covered. On
the other hand, some individual plans do not cover mental health services. Therefore,
it is difficult to determine if the use of adjusted 1987 data overestimates
or underestimates the actuarial value of individual plans relative to group
plans.
Study Results
Cost sharing and covered
benefits. We estimate
that patient cost sharing in individual plans is much greater than it is in
group plans, while covered benefits are more meager (Exhibit
1). In-network deductibles average $1,550 in individual insurance plans,
compared with $138 in employer-sponsored health plans; out-of-network deductibles
average $2,235 and $354, respectively.
Out-of-pocket spending limits are an important feature of insurance for protecting
patients from catastrophic financial liabilities when they are stricken with
serious illness. In individual FFS plans only 11 percent of beneficiaries have
an out-of-pocket limit below $2,000, whereas 56 percent of covered workers enjoy
such limits (Exhibit
1).
Group insurance plans had higher levels of coverage for all five covered benefits
selected for our analysis. Prescription drugs were covered for 97 percent of
persons with employer coverage but only 80 percent of those with individual
coverage. Virtually all persons with group health insurance had coverage for
inpatient and outpatient mental health services, compared with only 63 percent
(inpatient) and 48 percent (outpatient) of persons with individual coverage.
Actuarial value of individual
and group plans.
Among all users of health care, individual insurance covers on average 63 percent
of the bill, and group insurance covers 75 percent (Exhibit
2). The distribution of actuarial values in individual insurance is decidedly
different than in group insurance (not shown). For group insurance plans, most
plans have actuarial values clustered near the mean of 0.75, meaning that their
plan covers 75 percent of the medical bill. Sixty percent of group health plan
enrollees are enrolled in plans whose actuarial values are within ten percentage
points of this average (from 0.66 to 0.86). For individual insurance plans,
38 percent of enrollees are in plans having actuarial values ranging from 0.42
to 0.82. The five lowest individual plans had actuarial values of 0.11 to 0.18,
whereas the five plans with the highest actuarial values were concentrated at
0.90.
Because of high deductibles in individual plans, differences in actuarial values
between group and individual insurance are more dramatic for the bottom 50 percent
of users. Individual insurance covers just 30 percent of the bill for these
users; by contrast, group insurance covers 67 percent of the bill for these
users. For the top 25 percent of spenders, individual insurance pays 66 percent
of the bill; group insurance pays 85 percent.
Monthly premiums.
The average monthly premium for a healthy twenty-seven- year-old male (with
no medical conditions) in 2000 was $132 (Exhibit
3), one-third less than the average premium for group coverage in the ten
study states. Many plans with very low premiums compete in the individual insurance
market. Plans with premiums at the twenty- fifth percentile for a healthy twenty-seven-
year-old cost only $68 a month, 60 percent less than the premium cost for group
insurance plans at the twenty-fifth percentile of premiums.
By contrast, the average monthly premium in 2000 for a healthy fifty-five-year-old
male was $313, about 60 percent more than the average group health insurance
premium and 2.4 times as much as the cost of single coverage for a healthy twenty-seven-year-old
male. Many low-premium plans appeared in the sample for fifty-five-year-old
males, with the premium at the twenty-fifth percentile being $182.
The value of insurance.
The overused business term "value" usually connotes quality for the
money. To determine whether low- price plans provide much less financial protection,
we compared the average actuarial value of the four quartiles of individual
insurance, sorted by monthly premiums for fifty-five- year-old males (Exhibit
4). As premiums rise, actuarial value rises monotonically for low users
of health care; for all users and for high users, the third quartile has an
unexpected higher (but statistically insignificant) actuarial value than the
fourth quartile has.24 For the bottom 50 percent
of users, the lowest-price quartile of individual insurance plans covers only
6 percent of medical expenses, compared with 47 percent for the highest-price
quartile.
To estimate how much financial
protection individual and group insurance provides against major catastrophic
costs, we calculated the expected percentage of income that someone earning 200
percent of poverty is likely to spend out of pocket under individual and group
coverage (Exhibit
5).25 We computed these estimates for all health
care users, the top and bottom 50 percent of users, and the top 25 percent of
users. These calculations do not include out-of-pocket expenses for health insurance
premiums. For the top 25 percent of users, out-of-pocket spending for medical
services of $1,829 would constitute 11 percent of income for a person with income
at 200 percent of poverty level. In contrast, the top 25 percent of users with
group insurance coverage would spend $997, or 6 percent of their income.
Discussion
Through an analysis of four databases and using several assumptions to fix unknown
factors, this paper has estimated the cost and financial protection provided
by individual health insurance and compared that cost and protection with those
of group insurance. Some study findings confirm conventional wisdom. Cost sharing
in the form of higher deductibles in individual insurance plans far exceeds
that in group insurance. Many individual insurance plans cover neither prescription
drugs nor inpatient and outpatient mental health treatment, rendering covered
benefits inferior to benefits in group plans. Monthly premiums for a healthy
twenty-seven-year-old male were on average one-third less than the average cost
for single coverage in the group insurance market, but the monthly premium for
a healthy fifty-five-year-old male was 2.4 times as great as the cost for a
healthy twenty- seven-year-old male and far exceeded the average figure for
group insurance.
The percentage of likely incurred expenses paid by health plans (that is, plans'
actuarial value) averages 63 percent in individual insurance and 75 percent
in group insurance. For the lower 50 percent of users, individual insurance
covers only about 30 percent of the bill, versus 67 percent under group coverage.
Our results are consistent with the assertion that many low-cost policies are
available for the uninsured to purchase with a $1,000 tax credit-with some important
qualifications. For a healthy twenty-seven-year-old male, one-fourth of plans
on the market cost $68 or less a month, or $816 per year. However, for a healthy
fifty-five-year-old male (and very few men this age lack a medical history)
only one-quarter can get coverage that costs less than $2,184 per year. More
importantly, these low-cost plans would pay just 42 percent of incurred health
care costs for the individually insured population.
There are no data on premium increases for individual health insurance since
2000. The cost of group insurance rose 11.1 percent in 2001, and analysts project
similar or greater increases in 2002.26 Consequently,
the cost of individual insurance in 2002 may be 20 percent higher than the figures
reported here.
Actuaries and economists view the aim of insurance as protecting families from
large and unpredictable expenses. For the top 25 percent of health care users,
the average individual insurance policy would leave the insured person liable
for $1,829 in out-of-pocket expenses, or 11 percent of income for someone with
income at 200 percent of poverty. If a healthy fifty-five-year-old male received
a $1,000 tax credit and purchased a policy of average cost, premium expenses
plus out-of- pocket expenses would consume 17 percent of that person's income.
The major limitation of our study methods is that data on the number of persons
purchasing each product were not available. Hence, readers should view individual
insurance figures as simulated extrapolations, or "second- best estimates,"
and hence treat them with great caution.
Findings from this study are subject to another caveat. They reflect the current
individual insurance market-a market that is quite small. Mark Pauly and others
believe that with an infusion of tax-credit money, the individual insurance
market would grow, and insurers would no longer need to market their products
so intensively.27 As more healthy persons entered
the market, insurers would not need to underwrite as aggressively, either. This
would reduce administrative costs and thereby raise actuarial values and reduce
premiums. Others contend that individual insurance can never be efficient without
a strong set of market rules.28 Overcoming favorable
selection on the part of insurers requires strong market rules. To deter the
sickest persons from disproportionately purchasing health insurance-for example,
couples who wait to buy individual insurance until they plan on having a baby-an
individual mandate is necessary.
There are no prior natural experiments to determine who is correct about the
shape of individual insurance in a brave new world of tax credits. What is certain
is that in today's world, people who can pass the medical underwriting screen
buy a product that gives them far less protection than that given to their peers
with group insurance.

22. Our estimates of the loss of actuarial value due to preexisting
condition clauses is conservative. The Health Insurance Portability and Accountability
Act (HIPAA) of 1996 allows states to not provide guaranteed issuance for preexisting

who formerly held group insurance must have exhausted their COBRA benefits,
previously had eighteen months of continuous coverage, and applied for individual
coverage within sixty-three days of leaving their employer's coverage.

presence of a primary care gatekeeper. Many plans on the Web sites did not provide
