Aca Law: Understanding Its Historical Implementation

The Affordable Care Act (ACA), formally known as the Patient Protection and Affordable Care Act (PPACA), was signed into law by President Barack Obama on March 23, 2010. The ACA is a landmark federal statute and the most significant regulatory overhaul of the US healthcare system since the enactment of Medicare and Medicaid in 1965. The law addresses health insurance coverage, healthcare costs, and preventive care, with the primary goals of making affordable health insurance available to more people, expanding the Medicaid program, and supporting innovative medical care delivery methods to lower healthcare costs.

The ACA was signed into law by President Obama on March 23, 2010

On March 23, 2010, President Obama signed the Affordable Care Act into law. The law, also known as "Obamacare", was enacted to address health insurance coverage, healthcare costs, and preventive care.

The ACA was signed into law after a long and arduous political process. The bill was first passed by the House of Representatives on November 7, 2009, and then by the Senate on December 24, 2009. However, due to differences in the bills, negotiations were required to reconcile the two versions. This process was challenging, with President Obama needing to gain the support of moderate Democrats and bring Republican senators on board. Ultimately, the final bill was passed by both chambers of Congress, and President Obama signed it into law on March 23, 2010.

The ACA has three primary goals:

• To make affordable health insurance available to more people by providing subsidies, known as "premium tax credits," to households with incomes between 100% and 400% of the federal poverty level.
• To expand the Medicaid program to cover all adults with incomes below 138% of the federal poverty level, although not all states have participated in this expansion.
• To support innovative medical care delivery methods designed to lower the overall costs of healthcare.

The ACA has had a significant impact on healthcare in the United States. By 2016, the uninsured share of the population had roughly halved, with an additional 20 to 24 million people gaining coverage. This reduction in the uninsured rate was seen across all congressional districts in the country. The law also led to a slowdown in the growth of healthcare spending, including premiums for employer-based insurance plans.

In addition to these effects, the ACA has had a positive impact on health outcomes. A 2017 study found that the ACA reduced socioeconomic disparities in healthcare access. Additionally, ten years after its enactment, studies showed that the ACA had a positive effect on health and caused a reduction in mortality. The ACA has also been linked to improved health outcomes for specific populations, such as adults with mental and substance use disorders, trauma patients, cancer patients, and people living with HIV.

Despite its successes, the ACA has faced strong political opposition and ongoing efforts to repeal or modify it. However, public opinion has shifted over time, and by the end of 2023, a majority of registered voters (57%) approved of the law.

The ACA was amended by the Health Care and Education Reconciliation Act on March 30, 2010

The Affordable Care Act (ACA) was amended by the Health Care and Education Reconciliation Act on March 30, 2010. This amendment was enacted by the 111th United States Congress, using the reconciliation process. The Act was signed into law by President Barack Obama on the same day, at Northern Virginia Community College.

The Health Care and Education Reconciliation Act was passed by the U.S. House of Representatives on March 21, 2010, and by the Senate on March 25, 2010. The Act was passed in the House with a vote of 220-211, in the Senate with a vote of 56-43, and in the House again with a vote of 220-207 after two minor provisions relating to Pell Grants were stricken under the Byrd Rule.

The Health Care and Education Reconciliation Act of 2010 amended the ACA, or the Patient Protection and Affordable Care Act, which had been signed into law just seven days earlier, on March 23, 2010. The ACA is a comprehensive health care reform law that addresses health insurance coverage, health care costs, and preventive care. The Health Care and Education Reconciliation Act made several changes to the ACA, including increasing tax credits for purchasing insurance, eliminating special deals given to senators, lowering the penalty for not buying insurance, and closing the Medicare Part D "donut hole" by 2020.

The Health Care and Education Reconciliation Act is divided into two titles: one addressing health care reform and the other addressing student loan reform. The Act includes the Student Aid and Fiscal Responsibility Act, which was added as a rider. The inclusion of student loan reform in the Act was intended to give President Obama two key victories in overhauling the health care and student loan systems.

The ACA's major provisions came into force in 2014

The Affordable Care Act (ACA) was signed into law by President Obama on March 23, 2010, with the major provisions of the law coming into force in 2014. The ACA was a comprehensive health care reform law with three primary goals: making affordable health insurance available to more people, expanding Medicaid to cover all adults with income below 138% of the federal poverty level, and supporting innovative medical care delivery methods to lower the overall costs of health care.

The ACA's major provisions that came into force in 2014 included:

• Guaranteed issue and renewability of coverage: Insurers were required to provide coverage to any applicant, regardless of health status, gender, or other factors. This provision ended the practice of insurers denying coverage to people with pre-existing conditions or charging women higher premiums.
• Premium rating rules: Insurers were prohibited from adjusting premiums based on a person's health status. Premiums could only be varied based on family enrollment size, geography, age, and tobacco use.
• Essential health benefits: All health insurance plans were required to cover ten categories of essential health benefits, including ambulatory patient services, maternity and newborn care, mental health and substance use disorder services, rehabilitative services, preventive and wellness services, and pediatric services.
• Health insurance exchanges: State-level exchanges or the federal marketplace allowed individuals and small businesses to compare and purchase qualified health plans.
• Individual mandate: U.S. citizens without health insurance were required to pay a tax penalty.
• Employer mandate: Employers with 50 or more full-time employees were required to offer health insurance coverage or pay a penalty.
• Medicaid expansion: Federally funded Medicaid coverage was expanded to cover individuals earning up to 133% of the federal poverty level in certain states.
• Tax credits: Premium tax credits were made available to individuals or families earning between 100% and 400% of the federal poverty level who purchased health insurance through the exchanges.
• Small business tax credits: The ACA implemented the second phase of small business tax credits for qualified small businesses and small non-profit organizations, offering credits of up to 50% of the employer's contribution to employee health insurance.

The ACA's individual insurance market was radically overhauled

The Affordable Care Act (ACA), also known as the Patient Protection and Affordable Care Act (PPACA), was signed into law by President Barack Obama on March 23, 2010. The ACA's individual insurance market was radically overhauled, and many of the law's regulations applied specifically to this market.

The ACA introduced a much greater degree of standardization of benefits and cost-sharing levels for qualified health plans (QHPs) than existed before 2010. QHPs must provide essential health benefits in 10 categories of health services and must be designed according to 4 standard metal tiers based on cost-sharing levels. Bronze plans are designed to require 40% of spending, on average across all policyholders, to come from out-of-pocket (OOP) cost-sharing; Silver plans, 30%; Gold plans, 20%; and Platinum plans, 10%. Metal tiers, therefore, allow purchasers a choice of trade-offs between lower monthly premiums with higher OOP spending at the low end (i.e., Bronze plans) and higher monthly premiums with lower OOP spending at the high end (i.e., Platinum plans).

Despite the availability of subsidies and cost-sharing reductions, the reliance of the ACA on health insurance exchanges may both increase access to health insurance and simultaneously pose unintended barriers to access, particularly for low-income populations. These barriers can arise in two ways. The most publicized method is through the creation of narrow networks, where insurers offer plans and policies with fewer doctors and hospitals in an effort to keep premiums as competitive as possible. Whether narrow networks create actual, rather than perceived, barriers to care has not been well established yet through research. Nevertheless, the existence of narrow networks has created the perception that exchange-based QHPs are limiting access to a greater extent than did pre-ACA policies, despite the absence of adequate baseline data from pre-ACA years.

The second way that exchanges may create unintended barriers to access to care, particularly for low-income populations, is through the existence of high-deductible Bronze plans. Despite the availability of cost-sharing reductions for those who choose Silver plans, Bronze plans are still the second most popular choice; of the 12.7 million people who enrolled in exchange plans as of March 2016, 68% selected Silver plans while 23% selected Bronze plans. Because the deductibles for Bronze plans generally exceed $5,000 for an individual and $10,000 for a family, they effectively serve as catastrophic insurance and, thus, may create barriers to access for most services except preventive services, which are exempt from deductibles and copayments under the ACA.

The ACA's individual mandate required everyone to have insurance or pay a penalty. The mandate and limits on open enrollment were designed to avoid the insurance death spiral, minimize the free rider problem and prevent the healthcare system from succumbing to adverse selection. The mandate was intended to increase the size and diversity of the insured population, including more young and healthy participants to broaden the risk pool, spreading costs.

The ACA expanded Medicaid

The Affordable Care Act (ACA) was signed into law by President Obama on March 23, 2010, with the Health Care and Education Reconciliation Act serving as an amendment to the law on March 30, 2010. The ACA was a watershed moment in US public health policy, addressing health insurance coverage, healthcare costs, and preventive care. A key component of the ACA was the expansion of Medicaid to cover nearly all adults with incomes up to 138% of the Federal Poverty Level (about $20,783 for an individual in 2024).

Prior to the ACA, Medicaid covered approximately 18% of non-elderly Americans, including children, their parents, pregnant women, and those with disabilities. However, the ACA significantly expanded Medicaid eligibility, particularly for adults. Under the ACA, states were required to provide Medicaid coverage for adults aged 18 to 65 with incomes up to 133% (effectively 138%) of the federal poverty level, regardless of their age, family status, or health. This expansion of Medicaid was expected to provide coverage to low-income individuals, a population at greater risk for disparities in access to the healthcare system and health outcomes.

Several studies suggest that the expansion of Medicaid can reduce insurance-related disparities and improve access to healthcare for low-income individuals. As of 2024, 41 states (including Washington, D.C.) have adopted the Medicaid expansion, while 10 states have not. However, it is important to note that the Supreme Court ruled that the Medicaid expansion is voluntary for states, and as a result, some states have chosen not to participate. This has left millions of low-income individuals without insurance, as they fall into a "coverage gap" where they do not qualify for either Medicaid or subsidies for private insurance plans.

Despite the voluntary nature of the Medicaid expansion, the ACA's impact on Medicaid has been significant. It has provided an important step forward in addressing gaps in safety net coverage for low-income individuals and has the potential to improve self-reported health, increase the use of preventive and primary care services, and reduce financial strain due to medical illness.
