MEPS-HC Summary Data Tables Technical
Notes
This data in this
report were obtained in the first round of interviews for
the Household Component (HC)
of the Medical Expenditure Panel Survey (MEPS). MEPS is cosponsored
by the Agency for Healthcare Research and Quality (AHRQ) and the
National Center for Health Statistics (NCHS). MEPS-HC is a nationally
representative survey of the U.S. civilian noninstitutionalized
population that collects medical expenditure data at both the person
and household levels. The focus of MEPS-HC is to collect detailed
data on demographic characteristics, health conditions, health
status, use of medical care services, charges and payments, access
to care, satisfaction with care, health insurance coverage, income,
and employment. In other components of MEPS, data are collected
on the use, charges, and payments reported by providers; residents
of licensed or certified nursing homes; and the supply side of
the health insurance market.
The sample for MEPS-HC was selected from respondents to the National
Health Interview Survey (NHIS), which was conducted by NCHS. NHIS
provides a nationally representative sample of the U.S. civilian
noninstitutionalized population and reflects an oversampling of
Hispanics and blacks. MEPS-HC collects data through an overlapping
panel design. In this design, data are collected through a pre-contact
interview that is followed by a series of five rounds of interviews
over two and a half years. Two calendar years of medical expenditure
and utilization data are collected from each household and captured
using computer-assisted personal interviewing (CAPI). This series
of data collection rounds is launched again each subsequent year
on a new sample of households to provide overlapping panels of
survey data that, when combined with other ongoing panels, provide
continuous and current estimates of health care expenditures.

Derivation
of insurance status information
The household respondent was
asked if during the interview period anyone in the family
was covered by any of the
sources of public and private health insurance coverage
discussed in the following paragraphs. Coverage by Medicare
and TRICARE, formerly known as CHAMPUS/CHAMPVA, was measured
at the time of the interview. (CHAMPUS and CHAMPVA were
the Civilian Health and Medical Programs for the Uniformed
Services and Veterans’ Affairs.) All other sources
of insurance were measured for any time between January
1st and the interview date. Persons counted as uninsured
were uninsured throughout this time period.
Public coverage
For this report, individuals were considered to have
public coverage only if they met both of the following
criteria:
-
They were not covered by private insurance.
-
They were covered by one of the public programs discussed
below.
Medicare Medicare is a federally financed health insurance plan
for the elderly, persons receiving Social Security disability
payments, and most persons with end-stage renal disease.
Medicare Part A, which provides hospital insurance, is
automatically given to those who are eligible for Social
Security. Medicare Part B provides supplementary medical
insurance that pays for medical expenses and can be purchased
for a monthly premium.
TRICARE
TRICARE covers active-duty and retired members of the Uniformed Services and the spouses and children of active-duty, retired, and deceased members. Spouses and children of veterans who died from a service-connected disability, or who are permanently disabled and are not eligible for Medicare, are covered by TRICARE. When persons covered by TRICARE reach age 65, such persons become eligible for Medicare, and if they elect Medicare Part B, he or she is automatically covered under TRICARE For Life (TFL). A person covered by TRICARE will not lose TRICARE coverage upon attaining age 65 if that person is not eligible for Medicare. TFL is also provided to TRICARE members under age 65 who become eligible for Medicare and who pay the Medicare Part B premium. In this report, TRICARE coverage is considered to be public coverage.
Medicaid and State Children’s Health Insurance
Program
Medicaid and the State Children’s Health Insurance
Program (SCHIP) are means-tested government programs
jointly financed by Federal and State funds that provide
health care to those who are eligible. Eligibility criteria
vary significantly by State. Medicaid is designed to
provide health insurance coverage to families and individuals
who are unable to afford necessary medical care, while
SCHIP is designed to provide health insurance coverage
for uninsured low-income children. Respondents who did
not report Medicaid or SCHIP coverage were asked if they
were covered by any other public hospital/physician coverage.
These questions were asked in an attempt to identify
Medicaid or SCHIP recipients who might not have recognized
their coverage as Medicaid or SCHIP. In this report,
all coverage reported in this manner is considered public
coverage.
Private health insurance
Private health insurance was defined as insurance that
provides coverage for hospital and physician care (including
Medigap coverage). Insurance that provides coverage for
a single service only, such as dental or vision coverage,
was not counted. Private health insurance could have
been obtained through an employer, union, self-employed
business, directly from an insurance company or a health
maintenance organization (HMO), through a group or association,
or from someone outside the household.
Uninsured
The uninsured were defined as persons not covered by
Medicare, TRICARE, Medicaid, other public hospital/physician
programs, or private hospital/physician insurance (including
Medigap coverage) during the period from January 1st
through the time of the interview. Individuals covered
only by noncomprehensive State-specific programs (e.g.,
Maryland Kidney Disease Program) or private single-service
plans (e.g., coverage for dental or vision care only,
coverage for accidents or specific diseases) were not
considered to be insured.
^top
Health
insurance edits
For the Round 1 sample, minimal editing was performed on sources of public
coverage and no edits were performed on the private coverage variables. Health
insurance data were edited as described below.
Medicare
Medicare coverage was edited for persons age 65 and over but not for persons
under age 65. Persons age 65 and over were assigned Medicare coverage if they
met one of the following criteria: -
They answered "yes" to a follow-up question on whether they had received
Social Security benefits.
-
They were covered by Medicaid, other public hospital/physician coverage, or
Medigap coverage.
-
Their spouse was age 65 or over and covered by Medicare.
-
They were covered by TRICARE.
Medicaid
This report does not distinguish among sources of public insurance. Medicaid
or other public hospital/physician coverage was included when considering whether
an individual was covered only by public insurance.
TRICARE
Respondents age 65 and over who reported TRICARE coverage were instead classified
as covered by Medicare.
Private health insurance
Private insurance coverage was unedited and unimputed for Round 1 (Panel 5).
Individuals were considered to be covered by private insurance if the insurance
provided coverage for hospital/physician care. Medigap plans were included.
Individuals covered by single-service plans only (e.g., dental, vision, or
drug plans) were not considered to be privately insured. Sources of insurance
with missing information regarding the type of coverage were assumed to contain
hospital/physician coverage.

MEPS expenditures
Definition
Expenditures in this report refer to payments for health care services. More
specifically, expenditures in MEPS are defined as the sum of direct payments
for care provided during the year, including out-of-pocket payments and payments
by private insurance, Medicaid, Medicare, and other sources. Payments for over-the-counter
drugs, alternative care services, and phone contacts with medical providers
are not included in MEPS total expenditure estimates. Indirect payments not
related to specific medical events, such as Medicaid Disproportionate Share
and Medicare Direct Medical Education subsidies, also are not included.
The definition of expenditures used in MEPS is somewhat different from the
definition used in its predecessor surveys, the 1987 National Medical Expenditure
Survey (NMES) and the 1977 National Medical Care Expenditure Survey (NMCES),
where "charges" rather than "sum of payments" were used
to measure expenditures. This change was adopted because charges became a less
appropriate proxy for medical expenditures during the 1990s due to the increasingly
common practice of discounting charges. One impact of this change is that charges
associated with uncollected liability, bad debt, and charitable care (unless
provided by a public clinic or hospital) are not counted as expenditures.
Estimation methodology
Expenditure estimates in this report are based on the sum of total payments
for medical events reported in during the calendar year. The HC collected annual
data on the use of and associated expenditures for office and hospital-based
care, home health care, dental services, prescribed medicines, vision aids,
and other medical supplies and equipment. In addition, the MEPS Medical Provider
Component (MPC) collected expenditure data from a sample of medical and pharmaceutical
providers that provided care and medicines to sample people for that calendar
year. Expenditure data collected in the MPC are generally regarded as more
accurate than comparable data collected in the HC and were used to improve
the overall quality of MEPS expenditure data in this report. For a more detailed
description of the MPC, see Machlin and Taylor (2000).
Expenditure data were imputed to replace missing data, provide estimates for
care delivered under capitated reimbursement arrangements, and adjust household-reported
insurance payments because respondents were often unaware that their insurer
paid a discounted amount to the provider. This section contains a general description
of the approaches used for these three situations. A more detailed description
of the editing and imputation procedures is provided in the documentation for
the MEPS event-level files, which are available through the AHRQ Web site at
http://www.ahrq.gov/. For more information on the approach used to impute missing
expenditure data on prescribed medicines, see Moeller, Stagnitti, Horan, et
al. (2000).
Missing data on expenditures were imputed using a weighted sequential hot-deck
procedure for most medical visits and services. In general, this procedure
imputes data from events with complete information to events with missing information
but similar characteristics. For each event type, selected predictor variables
with known values (e.g., total charge; demographic characteristics; region;
provider type; and characteristics of the event of care, such as whether it
involved surgery) were used to form groups of donor events with known data
on expenditures, as well as identical groups of recipient events with missing
data. Within such groups, data were assigned from donors to recipients, taking
into account the weights associated with the complex MEPS survey design. Only
MPC data were used as donors for hospital-based events, while data from both
the HC and MPC were used as donors for office-based physician visits.
Because payments for medical care provided under capitated reimbursement arrangements
and through public clinics and Department of Veterans Affairs (VA) hospitals
are not tied to particular medical events, expenditures for events covered
under those types of arrangements and settings were also imputed. Events covered
under capitated arrangements were imputed from events covered under managed
care arrangements that were paid based on a discounted fee-for-service method,
while imputations for visits to public clinics and VA hospitals were based
on similar events that were paid on a fee-for-service basis. As for other events,
selected predictor variables were used to form groups of donor and recipient
events for the imputations.
An adjustment also was applied to some HC-reported expenditure data because
an evaluation of matched HC/MPC data showed that respondents who reported that
charges and payments were equal were often unaware that insurance payments
for the care had been based on a discounted charge. To compensate for this
systematic reporting error, a weighted sequential hot-deck imputation procedure
was implemented to determine an adjustment factor for HC-reported insurance
payments when charges and payments were reported to be equal. As for the other
imputations, selected predictor variables were used to form groups of donor
and recipient events for the imputation process.
In some situations, it was reported that one charge covered multiple contacts
between a sample person and a medical provider (e.g., obstetrical services,
orthodontia). The following example uses 1996 data to illustrate how this scenario
was handled in the estimation process. Total payments for the fee (sometimes
called a flat or global fee) were included if the initial service was provided
in 1996. For example, all payments for an orthodontist’s fee that covered
multiple visits over 3 years were included if the initial visit occurred in
1996. However, if a 1996 visit to an orthodontist was part of a flat fee for
which the initial visit occurred in 1995, then none of the payments for the
flat fee were included. Most of the expenditures for medical care reported
by MEPS participants were associated with medical events that were not part
of a flat-fee arrangement.
Respondents sometimes reported medical events for which, in actuality, no payments
were made. This situation could occur for several reasons, including when free
care or a free sample of medicine was provided, bad debt was incurred, or no
charge was made for a follow-up visit (e.g., after a surgical procedure). These
types of events were treated as valid $0 payments when developing the estimates
contained in this report.
Type-of-service categories
In addition to expenditures for total health services, expenses are classified
in this report into eight broad types of service: hospital inpatient, emergency
room , outpatient services, medical provider visits, prescribed medicines,
dental, home health, and other medical equipment and services. These categories
are described below and, where relevant, in the footnotes to the tables in
this report.-
Hospital inpatient services: This category includes room and board and
all hospital diagnostic and laboratory expenses associated with the basic facility
charge and payments for separately billed physician inpatient services.
-
Emergency Room services: This category includes hospital diagnostic and
laboratory expenses associated with the ER facility charge and payments for
separately billed inpatient services.
-
Outpatient services: This category includes outpatient diagnostic and laboratory
expenses associated with the basic facility charge and payments for separately
billed inpatient services.
-
Medical provider visits: This category covers expenses for visits to a medical
provider seen in an office-based setting.
-
Prescribed medicines: This category includes expenses for all prescribed
medications that were initially purchased or otherwise obtained during the
calendar year, as well as any refills.
-
Dental services: This category covers expenses for any type of dental
care provider, including general dentists, dental hygienists, dental technicians,
dental surgeons, orthodontists, endodontists, and periodontists.
-
Home health services: This category includes expenses for care provided
by home health agencies and independent home health providers. Agency providers
accounted for most of the expenses in this category.
-
Other medical equipment and services: This category includes expenses
for eyeglasses, contact lenses, ambulance services, orthopedic items, hearing
devices, prostheses, bathroom aids, medical equipment, disposable supplies,
and other miscellaneous items or services that were obtained, purchased, or
rented during the year.
Source-of-payment categories
Estimates of sources of payment presented in this report represent the percentage
of the total sum of expenditures paid for by each source. Sources of payment
are classified as follows.-
Out-of-pocket by user or family.
-
Private insurance: Includes payments made by insurance plans covering
hospital and medical care (excluding payments from Medicare, Medicaid, and
other public sources). Payments from Medigap plans or CHAMPUS and CHAMPVA (Armed-Forces-related
coverage) are included. Payments from plans that provide coverage for a single
service only, such as dental or vision coverage, are not included.
-
Medicare: A federally financed health insurance plan for the elderly,
persons receiving Social Security disability payments, and most persons with
end-stage renal disease. Medicare Part A, which provides hospital insurance,
is automatically given to those who are eligible for Social Security. Medicare
Part B provides supplementary medical insurance that pays for medical expenses
and can be purchased for a monthly premium.
-
Medicaid: A means-tested government program jointly financed by Federal
and State funds that provides health care to those who are eligible. Program
eligibility criteria vary significantly by State, but the program is designed
to provide health coverage to families and individuals who are unable to afford
necessary medical care.
-
Other public programs: Includes payments from the Department of Veterans
Affairs (excluding CHAMPVA); other Federal sources (Indian Health Service,
military treatment facilities, and other care provided by the Federal Government);
various State and Local sources (community and neighborhood clinics, State
and local health departments, and State programs other than Medicaid); and
Medicaid payments reported for people who were not enrolled in the Medicaid
program at any time during the year.
-
Other sources: Includes payments from Workers Compensation; other unclassified
sources (automobile, homeowner's, or liability insurance, and other miscellaneous
or unknown sources); and other private insurance (any type of private insurance
payments reported for people without private health insurance coverage during
the year as defined in MEPS).

Population
characteristics
Age
The respondent was asked to report the age of each family member as
of the date of each interview for each round of data collection. In
this report, age is usually based on the sample person’s age
as of the end of the year. If data were not collected during a round
because the sample person was out of scope (e.g., deceased or institutionalized),
then age at the time of the previous round was used.
Race/ethnicity
Classification by race and ethnicity is based on information reported
for each family member. Respondents were asked if the race of the sample
person was best described as American Indian, Alaska Native, Asian
or Pacific Islander, black, white, or other. They also were asked if
the sample person’s main national origin or ancestry was Puerto
Rican; Cuban; Mexican, Mexicano, Mexican American, or Chicano; other
Latin American; or other Spanish. All persons whose main national origin
or ancestry was reported in one of these Hispanic groups, regardless
of racial background, are classified as Hispanic. Since the Hispanic
grouping can include black Hispanic, white Hispanic, and other Hispanic,
the race categories of black, white, and other do not include Hispanic
people.
Health Insurance status
Individuals under age 65 were classified into the following three insurance
categories based on household responses to health insurance status
questions administered during each round of the MEPS-HC.
-
Any private health insurance: Individuals who, at any time during
the year, had insurance that provides coverage for hospital and physician
care (other than Medicare, Medicaid, or other public hospital/physician
coverage) are classified as having private insurance. Coverage by CHAMPUS/CHAMPVA
(Armed-Forces-related coverage) is also included as private health
insurance. Insurance that provides coverage for a single service only,
such as dental or vision coverage, is not included.
-
Public coverage only: Individuals are considered to have public
coverage only if they met both of the following criteria: 1) They were
not covered by private insurance at any time during the year. 2) They
were covered by one of the following public programs at any point during
the year: Medicare, Medicaid, or other public hospital/physician
coverage.
-
Uninsured: The uninsured are defined as people not covered by
Medicare, CHAMPUS/CHAMPVA, Medicaid, other public hospital/physician
programs, or private hospital/physician insurance at any time during
the entire year or period of eligibility for the survey. Individuals
covered only by noncomprehensive State-specific programs (e.g., Maryland
Kidney Disease Program, Colorado Child Health Plan) or private single-service
plans (e.g., coverage for dental or vision care only, coverage for
accidents or specific diseases) are not considered to be insured.
Individuals age 65 and over were classified into the following three
insurance categories:
-
Medicare only.
-
Medicare and private.
-
Medicare and other public.
Poverty status
Each sample person was classified according to the total annual income
of his or her family. Within a household, all individuals related by
blood, marriage, or adoption were considered to be a family. Personal
income from all family members was summed to create family income.
Possible sources of income included annual earnings from wages, salaries,
bonuses, tips, and commissions; business and farm gains and losses;
unemployment and Worker’s Compensation; interest and dividends;
alimony, child support, and other private cash transfers; private pensions,
individual retirement account (IRA) withdrawals, Social Security, and
Department of Veterans Affairs payments; Supplemental Security Income
and cash welfare payments from public assistance, Aid to Families with
Dependent Children and Aid to Dependent Children; gains or losses from
estates, trusts, partnerships, S corporations, rent, and royalties;
and a small amount of "other" income.
Poverty status is the ratio of family income to the corresponding Federal
poverty thresholds, which control for family size and age of the head
of family. Categories are defined as follows: -
Poor: This refers to persons in families with income less than
or equal to the poverty line and includes those who reported negative
income.
-
Near-poor: This group includes persons in families with income
over the poverty line through 125 percent of the poverty line.
-
Low income: This category includes persons in families with income
over 125 percent through 200 percent of the poverty line.
-
Middle income: This category includes persons in families with
income over 200 percent through 400 percent of the poverty line.
-
High income: This category includes persons in families with income
over 400 percent of the poverty line.
Region
Each MEPS sample person was classified as living in one of the following
four regions as defined by the Bureau of the Census: -
Northeast: Maine, New Hampshire, Vermont, Massachusetts, Rhode
Island, Connecticut, New York, New Jersey, and Pennsylvania.
-
Midwest: Ohio, Indiana, Illinois, Michigan, Wisconsin, Minnesota,
Iowa, Missouri, North Dakota, South Dakota, Nebraska, and Kansas.
-
South: Delaware, Maryland, District of Columbia, Virginia, West
Virginia, North Carolina, South Carolina, Georgia, Florida, Kentucky,
Tennessee, Alabama, Mississippi, Arkansas, Louisiana, Oklahoma, and
Texas.
-
West: Montana, Idaho, Wyoming, Colorado, New Mexico, Arizona,
Utah, Nevada, Washington, Oregon, California, Alaska, and Hawaii.
Place of residence
Individuals were identified as residing either inside or outside a
metropolitan statistical area (MSA) as designated by the U.S. Office
of Management and Budget (OMB), which applied 1990 standards using
population counts from the 1990 U.S. census. An MSA is a large population
nucleus combined with adjacent communities that have a high degree
of economic and social integration within the nucleus. Each MSA has
one or more central counties containing the area’s main population
concentration. In New England, metropolitan areas consist of cities
and towns rather than whole counties. Regions of residence are in accordance
with the U.S. Bureau of the Census definition.
Perceived health status
The MEPS respondent was asked to rate the health of each person in
the family at the time of the Round 1/3 and Round 2/4 interviews according
to the following categories: excellent, very good, good, fair, and
poor. Perceived health status in this report is based primarily on
responses obtained in the Round 2/4 interview. For persons with missing
health status in a round, the response for health status at the previous
round was used, if available. In the tables in this report, the five
health status categories are the following : (1) excellent, (2) very
good, (3)good health and (4) fair and (5)poor health.
Employment status
Persons were considered to be employed if they were age 16 and over,
and had a job for pay, owned a business, or worked without pay in a
family business at the time of the Round 1/3 interview.

Sample
design and accuracy of estimates
MEPS is designed to produce estimates at the national and regional
level over time for the civilian noninstitutionalized population
of the United States and some subpopulations of interest. Each MEPS
panel collects data covering a 2-year period, with the first five
MEPS panels spanning 1996-97, 1997-98, 1999-2000, and 2000- 2001.
The data in these summary data tables are from the first round of
data collection for the each of the MEPS Panels. The statistics presented
in this
report are affected by both sampling error and sources of nonsampling
error, which include nonresponse bias, respondent reporting errors,
interviewer effects, and data processing misspecifications. For a
detailed description of the MEPS survey design, the adopted sample
design, and methods used to minimize sources of nonsampling error,
see Cohen (1997) and Cohen, Monheit, Beauregard, et al. (1996). The
MEPS person-level estimation weights include nonresponse adjustments
and poststratification adjustments to population estimates derived
from the March Current Population Survey (CPS) based on cross-classifications
by region, MSA status, age, race/ethnicity, and sex. Note that the
2000 Health Insurance tables used the March 2000 CPS; the 1999 Health
Insurance tables used the March 1999 CPS etc.
Tests of statistical
significance were used to determine whether the differences between
populations exist at specified levels of confidence or whether they
occurred by chance. Differences were tested using Z-scores having
asymptotic normal properties at the 0.05 level of significance. Unless
otherwise noted, only statistical differences between estimates are
discussed in the text.
^top
Rounding
Estimates presented in the tables were rounded to the nearest 0.1
percent. Standard errors, presented in accompanying Tables A-D, were
rounded to the nearest 0.01, while for Table E they were rounded
to the nearest whole number. Mean and median expenditures are rounded
to the nearest dollar. Total expenditures are rounded to the nearest
million dollar unit. Population estimates in Tables 1-5 were rounded
to the nearest thousand. Therefore, some of the estimates presented
in the tables for population totals of subgroups will not add exactly
to the overall estimated population total.
^top
Comparisons with
other data sources
Differences between MEPS and CPS
Because of methodological differences, caution should be used when
comparing these data with data from other sources. For example, CPS
measures persons who are uninsured for a full year; NHIS measures
persons who lack insurance at a given point in time—the month
before the interview. The CPS interview that contains information
on the health insurance status of the population is conducted annually,
and NHIS collects insurance data on a continuous basis each year.
In addition, unlike MEPS, CPS counts as insured military veterans
whose source of health care is the Department of Veterans Affairs.
CPS also counts children of adults covered by Medicaid as insured.
For these preliminary estimates, MEPS did not consider these children
insured unless their families reported them as such.
Differences between MEPS and National Health Accounts estimates
MEPS and the National Health Accounts (NHA) of the Health Care Financing
Administration (HCFA) have substantial differences in methodologies
and objectives. In particular, the NHA are based on a composite of
data from multiple sources at the national level and are used primarily
to track aggregate medical expenditures in the U.S. economy. In contrast,
MEPS collects survey data on individuals that can be used to estimate
direct payments made for medical care and services purchased by the
civilian noninstitutionalized population. Data from MEPS are widely
used for behavioral and socioeconomic analyses of the relationship
between individual characteristics and health care spending.
National health care expenditure estimates from MEPS are lower than
those from the NHA for several reasons. First, the NHA include a
larger range of expenditures. For example, the NHA include expenditures
for over-the-counter drugs, nursing home care, program administration,
government public health activities, and construction, as well as
some hospital and physician revenues not associated with patient
care. Second, the NHA include health care expenditures for individuals
who are not members of the civilian noninstitutionalized population,
such as individuals in the military and those residing in nursing
homes, assisted living facilities, and prisons. Researchers at AHRQ
and HCFA estimate that adjustments for differences in the scope of
included expenditures and population reduce the NHA’s 1996
national estimate to about $604 billion, compared to the corresponding
1996 MEPS national estimate of $554 billion (Selden, Levit, Cohen,
et al., 2000). For the most part, the remaining difference is likely
to reflect some combination of (a) irreconcilable definition and
measurement differences between the NHA and MEPS and (b) statistical
uncertainty associated with sampling error in both MEPS and the NHA.
