For sample adults and sample children (and, prior to 2019, all persons) who currently have health insurance coverage through CHIP (HICHIPE), CHIPXCHG reports if the person's health insurance was obtained through a state or federal insurance marketplace (e.g. or a state Health Insurance Marketplace).

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 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.


There are no comparability issues in years 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.
