== Provisions ==
The ACA includes numerous provisions that take effect over a matter of years, including the expansion of [[Medicaid]] eligibility, the establishment of health insurance exchanges, and prohibiting health insurers from denying coverage due to pre-existing conditions. It introduced a shared responsibility requirement, commonly referred to as an individual mandate, that every person not covered by an employer sponsored health plan, Medicaid, Medicare or other public insurance programs, secure an approved private-insurance policy.

== Impact ==
The ACA has caused a significant reduction in the number and percentage of people without health insurance. The increases in coverage were accompanied by improvements in access to care, health, and financial security, according to multiple studies. The law has also been the subject of numerous political and legal challenges.

== Controversies ==
The ACA has been the subject of numerous political and legal controversies and challenges. In 2011, opponents of the law attempted to use the appropriations process to defund its implementation. In 2012, the law was upheld by the Supreme Court in [[National Federation of Independent Business v. Sebelius|NFIB v. Sebelius]]. In 2017, Republicans attempted and failed to repeal the law.

== Future ==
The future of the ACA is uncertain, with many changes proposed by various political leaders and policy makers. Despite numerous attempts at repeal, the ACA remains in effect. The ongoing political and legal challenges and potential future modifications to the law continue to create uncertainty about the ACA's long-term impact on the U.S. healthcare system.
