Findings on the characteristics of the remaining uninsured here differ somewhat from those in our other recent work due to differences in data (Current Population Survey versus American Community Survey); differences in year of analysis (2015 versus 20106); the fact that the current work benchmarks to administrative data on enrollment in marketplaces and Medicaid, thereby adjusting for underreporting of public insurance, whereas the prior research did not; and the use of a simulation model in the current work rather than relying strictly on self-reported data.

This last group includes those caught in the so-called “family glitch.” The ACA has been interpreted through regulation as prohibiting all family members from qualifying for marketplace premium tax credits if at least one member has an employer based insurance offer for single coverage with a direct worker contribution of less than 9.66 percent of income, regardless of the direct cost of family coverage.Google Scholar

These include: prohibitions on lifetime and annual benefit limits, prohibitions on rescissions, first dollar coverage of in-network preventive care, utilization of uniform explanation of coverage documents and standardized definitions, requirements for appeals processes for claims denials, and extension of dependent coverage to adults under age 26.Google Scholar

Many of these examples will apply to enrollees in the fully insured small group insurance market as well; however, extensions of ACA non-compliant plans through 2017 suggest that many of these individuals are still not enrolled in ACA compliant coverage.Google Scholar
