Gain in Insurance Coverage and Residual Uninsurance Under the Affordable Care Act: Texas, 2013-2016.

Objectives To examine the effects of the Affordable Care Acts (ACAs) Marketplace on Texas residents and determine which population subgroups benefited the most and which the least. Methods We analyzed insurance coverage rates among nonelderly Texas adults using the Health Reform Monitoring Survey-Texas from September 2013, just before the first open enrollment period in the Marketplace, through March 2016. Results Texas has experienced a roughly 6-percentage-point increase in insurance coverage (from 74.7% to 80.6%; Pu2009=u2009.012) after implementation of the major insurance provisions of the ACA. The 4 subgroups with the largest increases in adjusted insurance coverage between 2013 and 2016 were persons aged 50 to 64 years (12.1 percentage points; Pu2009=u2009.002), Hispanics (10.9 percentage points; Pu2009=u2009.002), persons reporting fair or poor health status (10.2 percentage points; Pu2009=u2009.038), and those with a high school diploma as their highest educational attainment (9.2 percentage points; Pu2009=u2009.023). Conclusions Many population subgroups have benefited from the ACAs Marketplace, but approximately 3 million Texas residents still lack health coverage. Adopting the ACAs Medicaid expansion is a means to address the lack of coverage.
