Description

In all years, HIOTHGOV indicates whether the person had health insurance coverage through a public program other than the public programs already asked about in the survey. For 1997 forward, in addition to excluding Medicare (for sample adults only beginning in 2019) and Medicaid, HIOTHGOV refers to public coverage other than a State-sponsored health care program, and for 1999 forward, also other than the Children's Health Insurance Program (CHIP). Beginning in 2019, sample children who indicated receiving Medicare were marked as affirmative for HIOTHGOV.

Over the years, the term "other" always referred to public insurance apart from the public programs already mentioned. The question order and the specific programs included in the interview prior to the question on "other public program" changed over time.

Except for 1992-1996, HIOTHGOV refers to coverage at the time of the interview; for 1992-1996, HIOTHGOV refers to coverage in the previous month.

Survey questions

For 1982 to 1996, respondents were asked a series of questions about whether family members had each of several types of public assistance coverage. For 1997 forward, respondents could select "other government program" from a list of different types of coverage.

The specific questions used to determine coverage through some other government program changed over time.

For 1997 forward respondents were first asked if they (and each family member) were covered by any kind of health insurance or some other kind of health care plan. For 1997 to 1999, only those with an affirmative answer to this initial question have responses to follow-up questions about the type of health insurance and the details of coverage, including HIOTHGOV.

For years prior to 1997, the relevant questions for HIOTHGOV referred to "public assistance" programs.

Prior to 1997, questions on coverage through military health care programs occurred after the question for HIOTHGOV.

For 1997 forward, Field Representative's Manuals describe "other government program" as a "catch-all category for any public program providing health care other than those" already categorized.

Comparability

Apart from changes in the universe, the basic meaning of HIOTHGOV is largely consistent over time. "Other" public assistance always referred to government programs other than Medicaid. Which additional programs were included depended on the year. Users should consult the detailed description of the "Data Collection Process" in the variable description for information about how question order and references to other specific programs varied over time.

HIOTHGOV is not comparable with recoded variables created by the NCHS staff for 1997 forward because the latter have been back-edited to verify accuracy of insurance coverage status (and the data used in HIOTHGOV were not back-edited).Most analysts studying only the period 1997 forward should use the back-edited variable HIOTHGOVE, rather than HIOTHGOV. Those studying a longer time period should use HIOTHGOV to maximize comparability.

The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
