The ACA was enacted with the goals of increasing the quality and affordability of health insurance, lowering the uninsured rate by expanding public and private insurance coverage, and reducing the costs of health care for individuals and the government. It introduced a number of mechanisms — including mandates, subsidies, and insurance exchanges — meant to increase coverage and affordability. The law also requires insurance companies to cover all applicants within new minimum standards and offer the same rates regardless of pre-existing conditions or sex. Additional reforms aimed to reduce costs and improve health care outcomes by shifting the system towards quality over quantity through increased competition, regulation, and incentives to streamline the delivery of health care.
On June 28, 2012, the United States Supreme Court upheld the constitutionality of the ACA's individual mandate as an exercise of Congress's taxing power in the case National Federation of Independent Business v. Sebelius. However, the court held that states cannot be forced to participate in the ACA's Medicaid expansion under penalty of losing their current Medicaid funding. Since the ruling, the law and its implementation have continued to face challenges in Congress and federal courts, and from certain state governments, conservative advocacy groups, and some small business organizations.
