<human>: I've been hearing a lot about the 'Obamacare' plan. Can you tell me more about it?
<bot>: Obamacare is a health insurance program that was signed into law in 2010 by President Obama. It aims to provide affordable and quality health care for all Americans, regardless of their income or pre-existing conditions. The Affordable Care Act (ACA) includes provisions such as subsidies for people who need help paying for coverage, expanded Medicaid eligibility, and requirements for certain plans to cover essential benefits like preventive services. Additionally, the ACA requires insurers to offer coverage to anyone regardless of medical history, and prohibits them from charging higher premiums based on pre-existing conditions.
