Description

HICHIPE indicates whether the person currently had health insurance coverage through the Children's Health Insurance Program (CHIP).

HICHIPE is a recoded variable created by the National Center for Health Statistics (NCHS) and included in the original NHIS public use data. HICHIPE, like other recoded health insurance variables in these data, is based on responses to a series of questions and by editing carried out by the NCHS.

Definition of SCHIP 

The State Children's Health Insurance Program (SCHIP) was established under the Balanced Budget Act of 1997 and provides federal funds to states to expand health insurance coverage to uninsured low-income children. States use SCHIP money to develop separate child health programs, expand their Medicaid programs, or both. Both Medicaid and CHIP are means-tested government health insurance programs.

As the Field Representative's Manual for 1999 forward notes, the name for the CHIP program varies across states. Interviewers were supplied with cards listing "State Names for Medicaid, CHIP, State-/Local-Sponsored, and Other Health Insurance Programs" in their state. These linked broad categories of insurance that were studied in the survey to recognizable public health insurance program names. For example, in 1999, the California CHIP program was called the "Healthy Families Program."

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.

 

The 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 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," and single service plans were also excluded.

 

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.

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 HICHIPE, 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 HICHIPE, IPUMS NHIS contains the following recoded insurance variables: HIHSE (Covered by Indian Health Service: Recode); HIPRIVATEE (Covered by private health insurance: 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 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.
