    Implications of the Affordable Care Act for People With HIV Infection and the Ryan White HIV/AIDS Program: What Does the Future Hold?

    Issue Brief

    There are numerous aspects of the Affordable Care Act that will be important for people with HIV in the U.S., -- however, it is unlikely that these changes will address all the needs of people with HIV. The Ryan White HIV/AIDS Program will thus remain crucial for the provision of adequate health care to HIV-infected individuals, but it will need to change. Changes in the Ryan White Program’s role will depend largely on state decisions on Medicaid expansion and health care marketplaces. This article, published in the September/October issue of Topics in Antiviral Medicine, summarizes a presentation by Jennifer Kates of the Kaiser Family Foundation at the IAS–USA continuing education program held in New York, New York, in April 2013.

    Report

    On January 1, 2014, many key provisions of the Affordable Care Act (ACA) will start to go into effect, including the expansion of Medicaid to low-income adults and the launch of new Medicaid eligibility and enrollment processes, which are designed to move toward a coordinated enrollment system across health coverage programs, including Medicaid, CHIP, and the new Health Insurance Marketplaces.

    Issue Brief

    To help states launch the Affordable Care Act (ACA) Medicaid expansion and efficiently enroll eligible individuals, CMS has offered states a series of facilitated enrollment options.

This issue brief provides an overview of the new “fast track” enrollment options, including how they have been implemented, their impacts, and key lessons learned. It is based on a series of interviews with state officials in Arkansas, Illinois, Oregon and West Virginia conducted by Manatt Health Solutions and the Kaiser Commission on Medicaid and the Uninsured in October 2013.
