This issue brief provides an overview of the potential impact not extending enhanced ACA premium tax credits could have on people with HIV and the Ryan White HIV/AIDS Program. Enhanced credits have improved insurance coverage affordability for millions of people, including those with HIV. People with HIV may be particularly vulnerable, given that they are more likely to have Marketplace plans and many also rely on the federally-funded Ryan White HIV/AIDS Program to help cover plan costs. Loss of coverage and increased costs could lead to disruptions in care for people with HIV which could have serious implications for individual and public health.
