For sample adults and sample children who currently have health insurance coverage through Medicaid, MCAIDPREM reports if the person's Medicaid plan has an enrollment fee or premium. Prior to 2019, this variable was available for all person with Medicaid coverage.

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.

Persons included in the universe are persons who were classified as having health insurance coverage through Medicaid in the back-edited variable HIMCAIDE. This is recommended as the most reliable source of information about the type of insurance coverage compared to that provided by respondents' original unedited answers about their insurance type.


MCAIDPREM is completely comparable 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.
