Description
HIMILITE indicates whether the person currently has health insurance coverage through some form of military health insurance. For those with military health insurance, HIMILITE distinguishes between those who have: 1) Military or VA health insurance only; 2) CHAMPUS, TRICARE, or CHAMP-VA coverage only; 3) military health insurance coverage from both of these groups; and 4) military health insurance of an unspecified type.
Definitions of Types of Military Health Insurance
Military Health Care provides medical care on military bases to current armed forces members and their dependents. Medical care from the VA is available to honorably discharged veterans who either have a service connected illness, injury, or disability, or whose incomes are near or below poverty. The Field Representative's Manual for 1997-2003 provided the following definition for this first set of military health care programs: "Military health care/VA refers to health care available to active duty personnel and their dependents; in addition, the VA provides medical assistance to veterans of the Armed Forces, particularly those with service-connected ailments."
The Civilian Health and Medical Program Uniform Service of the Department of Defense (CHAMPUS) is a health care benefits program that provides in-patient and out-patient care from civilian sources and Military Treatment Facilities, on a cost sharing basis. In the late 1990s, a managed care approach was phased in, under the name TRICARE. Retired members of the military are eligible for such coverage, as are the dependents of active-duty, retired, and deceased military.
The Civilian Health and Medical Program of the Department of Veterans Affairs (CHAMPVA) is a health benefits program in which the Department of Veterans Affairs shares the cost of health care services and supplies with eligible beneficiaries. Persons eligible for TRICARE/CHAMPUS are not eligible for CHAMPVA coverage. Persons potentially eligible for CHAMPVA coverage are: the spouse or child of a veteran who has been rated permanently and totally disabled for a service-connected disability by the VA; the surviving spouse or child of a veteran who died from a VA-rated service connected disability; the surviving spouse or child of a veteran who was at the time of death rated permanently and totally disabled; or the surviving spouse or child of a military member who died in the line of duty.
The Field Representative's Manual provided two definitions for this second set of military health care programs. For 1997-2000, the Manual stated, "CHAMPUS (Comprehensive Health and Medical Plan for the Uniformed Services) provides health care in private facilities for dependents of military personnel on active duty or retired for reasons other than disability. TRICARE is the 'managed care' version of CHAMPUS. CHAMP-VA (Comprehensive Health and Medical Plan of the Veterans Administration) provides health care for the spouse, dependents, or survivors of a veteran who has a total, permanent service-connected disability." The definition in the Manual for 2001 was more extensive:
Data Editing and Recoding
During the course of data editing, the NCHS discovered many errors in the responses to questions about insurance coverage. Often, respondents misclassified the type of insurance they had. This might be shown, for example, by a mismatch between the verbatim name of an insurance plan and the type of insurance coverage the person selected from the categories on the card.
Accordingly, the NCHS created a series of recoded insurance variables. For these recoded insurance variables, such as HIMILITE, the data are back-edited, taking into account such factors as the proper classification of the verbatim names of insurance plans and responses to questions about why insurance coverage had stopped. The NCHS strongly advises analysts to use these recoded insurance variables as a more reliable source of information about the types of insurance coverage than is provided by respondents' original and unedited answers about their insurance type.
Related Variables
In addition to HIMILITE, IPUMS NHIS contains the following recoded insurance variables: HIHSE (Covered by Indian Health Service: Recode); HIPRIVATEE (Covered by private health insurance: Recode); HICHIPE (Covered by Children's Health Insurance Program: Recode); HIMCAIDE (Covered by Medicaid: Recode); HIMCAREE (Covered by Medicare: Recode); HISTATEE (Covered by other state-sponsored health plan: Recode); and HIOTHGOVE (Covered by other government program: Recode).
Comparability
The basic meaning and universe for this variable are consistent over time. Comparability may, however, be limited by changes in the questions used to gather the information used for back-editing the data, and by changes in the back-editing procedures used by the NCHS.
For example, beginning in 2018, NHIS added a new question targeting veterans who had not previously indicated their VA coverage. This addition was intended to address the undercount of VA healthcare previously observed in NHIS estimates, and NHIS incorporated the information gathered by this new question into the construction of HIMILITE. As a result, there may be an increase in the number of persons identified as covered by military health insurance starting in 2018, but this is likely due to a change in measurement rather than a "real" increase.
