Purpose of Review: Passage of the Affordable Care Act (ACA) in 2010 and subsequent Medicaid expansion has influenced access to HIV treatment and care in the USA. This review aims to evaluate whether the implementation of these policies has impacted progress toward UNAIDS 90-90-90 goals., Recent Findings: Preliminary evidence has emerged suggesting that the ACA and Medicaid expansion has increased the likelihood of HIV testing and diagnosis, reduced the number of people unaware of HIV infection, and increased the number of people on antiretroviral therapy (ART) who are virally suppressed. While the ACA is associated with some progress toward 90-90-90 goals, more years of data after policy implementation are needed for robust analysis. Methods including difference-in-differences, instrumental variables, and propensity scores are recommended to minimize bias from unmeasured confounders and make causal inference about non-random Medicaid expansion among states.

In the United States (U.S.), health care policy plays a critical role in ensuring adequate care for people living with HIV (PLWH), eliminating new HIV infections, and reducing health disparities. The 2010 Patient Protection and Affordable Care Act (ACA) was designed to make health care more accessible, of higher quality, and more affordable. Many provisions of the ACA are considered relevant to HIV care and prevention. Because PLWH have unique care needs and many groups at risk for infection are members of vulnerable populations, timely and comprehensive evaluation of the ACA in terms of HIV is critical. In this paper, we discuss components of the ACA relevant to HIV care and prevention, describe their anticipated and initial effects, and finally, outline a research agenda to inform future HIV programming and policy.
