Codes and Frequencies
Description
HIOTHGOVE indicates, from 1997 forward, whether the person currently has health care coverage provided by a public program at the time of the interview other than Medicare (for sample adults only beginning in 2019), Medicaid, CHIP/SCHIP (1999 forward), Military health care/VA, TRICARE/CHAMPUS/CHAMP-VA, Indian Health Service, or a State- sponsored public health insurance plan.
In 1992, this variable refers to insurance coverage during the month prior to the interview. All missing data in 1992 were imputed by the NHIS. Please refer to HIOTHGOVEFL to identify persons with imputed data.
HIOTHGOVE is a recoded variable created by the National Center for Health Statistics (NCHS) and included in the original NHIS public use data. HIOTHGOVE, like other recoded health insurance variables in these data, is based on responses to a series of questions and editing carried out by the NCHS.
Definitions
According to the Field Representative's Manual for 1997 forward, the expression "Other Government Program" is a "catch-all category for any public program providing health care other than those" already categorized. More specifically, "other government program" refers to public health insurance coverage from a source other than the following: Medicare (HIMCAREE, for sample adults only beginning in 2019); Medicaid (HIMCAIDE); Children's Health Insurance Program (HICHIPE); military health insurance (including Military Health Care/VA and TRICARE/CHAMPUS/CHAMP-VA) (HIMILITE); Indian Health Service (HIHSE); and State-sponsored public health care coverage plans (HISTATEE).
Data Collection Process
In the survey for 1997 forward, interviewers first asked, "Are you covered by health insurance or some other kind of health care plan?"
Respondents were instructed to "Include health insurance obtained through employment or purchased directly as well as government programs like Medicare and Medicaid that provide medical care or help pay medical bills." In 1997-2003 the survey form instructed interviewers to only read the preceding statement "if necessary."
Individuals who had an affirmative response to the preceding question were asked, "What kind of health insurance or health care coverage do you have?" Respondents selected the appropriate response from a card listing various types of insurance coverage.
Choices included:
- Private health insurance (2004 forward)
- Private health insurance plan from employer or workplace (1997-2003)
- Private health insurance plan purchased directly (1997-2003)
- Private health insurance plan through a State or local government program or community program (1998-2003)
- Medicare (1997 forward)
- Medi-Gap (1997 forward)
- Medicaid (1997 forward)
- CHIP (Children's Health Insurance Program) (1999 forward)
- Military Health Care/VA (1997-2003)
- Military Health Care (CHAMPUS/TRICARE/CHAMP-VA) (1997-2018)
- Military related health care: TRICARE (CHAMPUS)/VA health care/CHAMP-VA (2019 forward)
- Indian Health Service (1997 forward)
- State-sponsored health plan (1997 forward)
- Other government program (1997 forward)
- Single Service Plan (e.g., dental, vision, prescriptions) (1999 forward)
- No coverage of any type (2000 forward)
Respondents could pick more than one type of insurance and interviewers were instructed to mark all that applied.
Respondents were consistently instructed to exclude private plans that "only provide extra cash while hospitalized," while the treatment of single service plans varied by year.
In 1997-1998 respondents were also instructed to "EXCLUDE private plans that ... pay for only one type of service (nursing home care, accidents, or dental care)." Beginning in 1999, "Single Service Plan" was added as a possible response, and, consequently, the instructions were changed to read, "INCLUDE those [private plans] that pay for only one type of service (nursing home care, accidents, or dental care)."
Follow-up questions collected information about the names of coverage plans and confirmed the lack of any type of coverage for the uninsured.
In follow-up questions, interviewers recorded the names of up to four private health insurance plans. If the person was reported as covered by CHIP (beginning in 2000), by a state-sponsored health plan, or by another public program (other than Medicaid) that paid for health care, the interviewer recorded the name of that plan. The placement and wording of these questions about the names of specific government health care plans varied across years.
For persons initially reported as not having health care coverage of any kind, interviewers asked whether the person had Medicare coverage, Medicaid coverage, coverage via a Medicaid program or non-Medicaid state-sponsored health insurance program with the appropriate name for the state, CHAMPUS or CHAMPVA coverage, or any private insurance. For those who acknowledged any such coverage, the interviewer repeated the series of questions mentioned above to determine the specific type of coverage.
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 HIOTHGOVE, 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 HIOTHGOVE, IPUMS NHIS contains the following recoded insurance variables: HIPRIVATEE (Covered by private health insurance: Recode); HIHSE (Covered by Indian Health Service: Recode); HICHIPE (Covered by Children's Health Insurance Program: Recode); HIMILITE (Covered by military health insurance: Recode); HIMCAIDE (Covered by Medicaid: Recode); HIMCAREE (Covered by Medicare: Recode); HISTATEE (Covered by other state-sponsored health plan: Recode); and HINOTCOVE (No coverage of any type: Recode).
Comparability
The basic meaning of this variable and its universe 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.
Additionally, changes in the list of coverage types that respondents could report having may affect comparability over time. Respondents select types of insurance from a list that includes private, Medicare, Medi-gap, Medicaid, military health care/VA, CHAMPUS/TRICARE/CHAMP-VA, Indian Health Service, a state-sponsored plan, AND other government program. In 1998, respondents could choose among different types of private health insurance. In 1999, single service plans and CHIP were added as response options. In 2000, they could select not having any type of coverage. In 2004, the survey reverted to a single response option for private health insurance and the military health care option was updated to include TRICARE/VA/CHAMP-VA. Beginning in 2019, sample children who indicated Medicare coverage were marked as affirmative on HIOTHGOVE, whereas sample adults with Medicare coverage were marked as affirmative on HIMCAREE. So, in 2019 forward, "other" includes Medicare coverage for sample children, but not for sample adults.
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.
