Human: I've been hearing a lot about a new health care bill that is being debated in Congress. What do I need to know about this? Assistant: 
The Affordable Care Act (ACA) has been amended several times since it was passed in 2010, and the current version of the law is called the American Health Care Act. It proposes changes to the individual insurance market, Medicaid, and subsidies for people buying insurance on their own. The ACA expanded Medicaid eligibility and provided tax credits to help people buy private coverage. This new bill would roll back some of these provisions and replace them with different ones.
