Why did the Affordable Care Act raise coverage?
This article discusses NBER Working Paper No. 22213 on Premium Subsidies, the Mandate,and Medicaid Expansion: Coverage Effects of the Affordable Care Act by researchers Molly Frean, Jonathan Gruber, and Benjamin Sommers. The study’s key result is that the ACA’s premium subsidies led to a 0.85 percentage point increase in coverage, while the expansion of Medicaid to newly eligible individuals led to a 0.44 point increase.

Gaining coverage in 2014: new estimates of marketplace and Medicaid transitions.
The researchers used data from the Medical Expenditure Panel Survey-Household Component to examine coverage transitions for nonelderly US adults. They found that 71.5 percent of Marketplace enrollees in 2014 had some period of uninsurance before enrollment. In Medicaid expansion states, 17.4 percent of adults who were uninsured throughout 2013 gained Medicaid coverage in 2014, compared with only 5.6 percent in those states between 2012 and 2013.

Insurance churning rates for low-income adults under health reform: lower than expected but still harmful for many.
The researchers explored the frequency and implications of changes in insurance coverage over time (i.e., "churning,")through surveying low-income adults in Kentucky, which used a traditional expansion of Medicaid; Arkansas, which chose a "private option" expansion that enrolled beneficiaries in private Marketplace plans; and Texas, which opted not to expand. They found that churning was associated with disruptions in physician care and medication adherence, and increased emergency department use.

First year open enrollment findings: health insurance coverage for Asian Americans and the role of navigators.
The role of navigators has been shown to increase enrollment rates of public insurance programs. Cambodian, Chinese, Vietnamese, Korean, and Laotian community-based organizations were able to reach individuals for whom the percentage of uninsured is disproportionately high. A community-level intervention was implemented that was associated with increases in first year marketplace enrollment and greater likelihood of obtaining a primary care physician.

Accountability across the continuum: the participation of postacute care providers in accountable care organizations.
The authors examined the extent to which accountable care organizations (ACOs) formally incorporate postacute care providers. They found that ACOs with a relationship with a postacute care provider are more likely to have advanced transition management, end of life planning, readmission prevention, and care management capabilities. However, many ACOs have not formally engaged postacute care.

Changes in health status and care use after ACA expansions among the insured and uninsured.
The authors investigated average health status and use of health care following the Affordable Care Act's insurance expansion provisions in 2014, finding that Medicaid enrollees and the uninsured were both healthier in 2014 than those respective groups were in 2013, but that those with individual private insurance coverage appeared less healthy as a group.

Evidence suggests that the ACA's tobacco surcharges reduced insurance take-up and did not increase smoking cessation.
The authors examined the effect of tobacco surcharges on insurance status and smoking cessation in the first year of the health insurance exchanges' implementation, among adults most likely to purchase insurance from them. Their findings suggest that tobacco surcharges conflicted with a major goal of the Affordable Care Act - increased financial protection - without increasing smoking cessation.

Access to mental health care increased but not for substance use, while disparities remain.
The researchers assessed whether early implementation of Affordable Care Act (ACA) Medicaid expansion and state health insurance exchanges increased access to mental health and substance use treatment among those in need and whether these changes differed by racial/ethnic group. They found that mental health treatment rates increased significantly but found no evidence of a reduction in the wide racial/ethnic disparities in mental health treatment that preceded ACA expansion from 2005 to 2013.

California's early coverage expansion under the Affordable Care Act: a county-level analysis.
The researchers assessed the coverage effects of California's 2011 Low-Income Health Program (LIHP), enacted as an "early expansion" under the Affordable Care Act (ACA), and to demonstrate the feasibility of using Census data to measure county-level coverage changes. They concluded that California's 2011 expansion produced significant increases in public coverage for low-income individuals, particularly Latinos.

Health reform and coverage changes among Native Americans.
This study evaluated changes in insurance and Indian Health Service (IHS) coverage among Native Americans following the Affordable Care Act’s (ACA) implementation. It concluded that the ACA was associated with significant coverage increases for Native Americans, primarily in Medicaid expansion states, consistent with national trends for all racial/ethnic groups. Nationally, much of the coverage increase occurred among Native Americans without connections to IHS.

PPACA and low-income people living with HIV: 2014 qualified health plan enrollment in a Medicaid nonexpansion state.
This review examined qualified heallth plan enrollment of AIDS Drug Assistance Programs clients in Virginia, a Medicaid nonexpansion state, and explored some issues that affect people living with HIV in other Medicaid nonexpansion states. The authors recommend that as healthcare delivery models shift, the effects on patients and health outcomes achieved should be monitored, particularly for chronic diseases such as HIV.

Risk-adjustment simulation: plans may have incentives to distort mental health and substance use coverage.
The authors examined health plan incentives to limit covered services for mental health and substance use disorders under the risk-adjustment system used in the health insurance Marketplaces. They documented how Marketplace risk adjustment does not remove incentives for plans to limit coverage for services associated with mental health and substance use disorders.

Update on the Affordable Care Act. King v. Burwell and Obergefell v. Hodge.
This paper described two cases that potentially threatened the Affordable Care Act. In 2015, in King v Burwell, the plaintiffs challenged whether people who purchased health insurance in states that use the federal insurance marketplace rather than a state-run marketplace, were eligible to receive insurance premium subsidies. The Court ruled six to three in support of the legality of subsidies regardless of the type of marketplace states use. Also in 2015, the Supreme Court heard a landmark case, Obergefell v Hodge, in which the Court upheld the right for two people of the same sex to marry.

Little change seen in part-time employment as a result of the Affordable Care Act.
There has been speculation that the Affordable Care Act's coverage provisions and employer mandate have led to an increase in part-time employment. Using the Current Population Survey for the period 2005-15, the researchers examined data on weekly hours worked by firm size, reason for working part time, age, education, and health insurance. They found only limited evidence to support this speculation.

Medicaid expansion did not result in significant employment changes or job reductions in 2014.
To view the impact of the Affordable Care Act (ACA) on current labor market participation, the researchers analyzed labor-market participation among adults with incomes below 138 percent of the federal poverty level, comparing Medicaid expansion and nonexpansion states and Medicaid-eligible and -ineligible groups, for the pre-ACA period (2005-13) and the first fifteen months of the expansion (January 2014-March 2015). Medicaid expansion did not result in significant changes in employment, job switching, or full- versus part-time status.
