Codes and Frequencies
Description
For sample adults and sample children (and, prior to 2019, all persons) who currently have health insurance coverage through CHIP (HICHIPE), CHIPPREM reports if the person's CHIP plan has an enrollment fee or premium. Beginning in 2015, respondents were no longer asked about an enrollment fee and were instead asked, "Do you or a family member pay a premium for this CHIP plan?"
New questions were added to the Health Insurance section of the NHIS Family core in 2014 to obtain details about whether plans (both private and public) were obtained through Healthcare.gov or the person's state Health Insurance Marketplace, whether there is an enrollment fee or premium (public plans only), and whether the premium is based on income (expanded to include public plans). For more information on these questions, please refer to MCAIDXCHG.
Comparability
Other than the change in the wording of the survey text between 2014 and 2015 forward, there are no comparability issues before 2019.
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.
