Aca Marketplace: Insuring Millions

The Affordable Care Act (ACA) has led to millions more Americans gaining health insurance since its passage in 2010. By 2016, nearly 20 million more people had coverage than before the ACA was passed, and the uninsured rate among US adults ages 19 to 64 dropped to 12.4%. In 2022, a record total of over 35 million people had enrolled for ACA coverage, and in 2024, 21.3 million people selected an ACA plan during the Open Enrollment Period.

In early 2023, an estimated 18.2 million people had individual market coverage

The Affordable Care Act (ACA) established the Health Insurance Marketplace® as a means to extend health insurance coverage to millions of uninsured Americans. The Marketplace is a shopping and enrollment service for medical insurance, available online at HealthCare.gov. Some states run their own marketplaces, while the federal government manages an exchange open to residents of other states.

The Marketplace is available to those who don't have access to health insurance through employer-sponsored plans. It enables various insurers to compete for customers by offering a variety of plans based on cost and need. The plans are categorized into four tiers: bronze, silver, gold, and platinum, in order of least to greatest coverage. The highest tier, platinum, includes plans that cover approximately 90% of health expenses but is also the most costly.

Lower-income individuals and families can qualify for extra savings on all the health insurance plans offered on the exchange through premium tax credits and cost-sharing reductions. The ACA has also removed the penalty that individuals had to pay for not having health insurance.

The Biden-Harris Administration has shown a continued commitment to making health insurance available and affordable for everyone. In 2024, a record-breaking 21.3 million people chose ACA Marketplace Coverage, with about a fourth of those being new to the Marketplaces.

The number of people with ACA-compliant coverage is at a record high

The number of people with ACA-compliant coverage has reached a record high, with more than 35 million people enrolled in ACA-related coverage as of early 2022. This includes over 21 million people enrolled in Medicaid expansion coverage, which has been a key driver of the increase in ACA-compliant coverage. The Biden-Harris Administration's commitment to making health insurance accessible and affordable for everyone has played a crucial role in this achievement.

The Affordable Care Act (ACA) marketplaces, which opened in 2014, have experienced fluctuations in insurer participation. However, since 2019, there has been a steady increase in the number of insurers entering the market or expanding their service areas. This has resulted in more options for consumers, with 78% of enrollees having a choice of three or more insurers in 2021. The number of people enrolled in individual market coverage has also grown, reaching an estimated 18.2 million in early 2023—the highest since 2016.

The ACA has had a significant impact on reducing the number of uninsured Americans. By 2016, nearly 20 million more people had gained coverage compared to before the ACA was passed, and the uninsured rate dropped to a historic low. While there was a slight increase in the number of uninsured people in 2017, the overall trend has been positive. As of early 2022, the uninsured rate approached an all-time low of 8.8% for the full population.

The success of the ACA can be attributed to various factors, including enhanced subsidies, increased outreach, and extended enrollment periods. The American Rescue Plan Act (ARPA) and the Inflation Reduction Act have also played a crucial role in making coverage more affordable, with four out of five HealthCare.gov customers finding plans for $10 or less per month after subsidies. Additionally, the Biden-Harris Administration's efforts to expand access to affordable, comprehensive coverage have been instrumental in driving up enrollment numbers.

Looking ahead, the upcoming open enrollment period is expected to be one of the busiest yet, with many people expected to check their eligibility for expanded subsidies under the Inflation Reduction Act. The continued commitment to making health insurance accessible and affordable is expected to further increase the number of people with ACA-compliant coverage.

The uninsured rate among US adults ages 19-64 was 12.4% in 2018

In 2018, eight years after the Affordable Care Act (ACA) was passed, the uninsured rate among US adults aged 19-64 was 12.4%. This was statistically unchanged from 2016, despite attempts by the Trump administration and Congress to weaken the law.

The ACA has been successful in providing more people with health insurance. However, a higher proportion of US adults are now "underinsured", with the greatest growth in underinsured rates occurring among Americans in employer-based health plans.

In 2019, the uninsured rate for people aged 19-34 increased by 0.4% to 15.6%. This age group had the highest uninsured rates of any age group in the US, according to the 2019 American Community Survey (ACS).

The number of people enrolled in ACA Marketplace coverage has reached a record high. As of early 2023, an estimated 18.2 million people have individual market coverage, the highest since 2016. This increase in Marketplace enrollment can be attributed to enhanced premium assistance and boosted outreach.

The Biden-Harris Administration announced that 21.3 million people selected an ACA Health Insurance Marketplace plan during the 2024 Open Enrollment Period. This included about five million new enrollees and 16 million people who renewed their coverage.

The ACA continues to be a successful federal program, providing millions of people and their families with affordable health care coverage and peace of mind.

The number of insurers per state ranges from one company to thirteen

The Affordable Care Act (ACA) marketplaces have seen a constant shift in the number of insurers since their opening in 2014. Companies have entered or exited the market, and expanded or reduced their footprint in states. In 2021, the average number of insurers per state was 5.0, ranging from one company operating in Delaware to thirteen operating in Wisconsin. This is an increase from 3.5 insurers per state in 2018 but still below the peak of 6.0 in 2015.

The number of consumers with multiple insurer options has been steadily growing. In 2021, 78% of enrollees had a choice of three or more insurers, up from 67% in 2020 and 58% in 2019. Over 200 counties had 5 or more insurers in 2021, while only 10% of counties had a single insurer, down from 52% in 2018.

The variation in insurer participation across states is influenced by factors such as rural and metropolitan areas. In 2021, metro-area counties had an average of 3.1 insurers, compared to 2.5 insurers in non-metro counties. This disparity is significant as 87% of enrollees lived in metropolitan counties.

The stability and attractiveness of the individual market have drawn new entrants and expansions, contributing to steady premiums and profits for insurers. Despite the challenges posed by the pandemic, insurer participation in the ACA marketplaces has been on an upward trajectory, providing consumers with more options and improving access to affordable health coverage.

The uninsured rate approached an all-time low by the end of 2021

The Affordable Care Act (ACA) has been instrumental in expanding health insurance coverage and reducing the uninsured rate in the United States. As of early 2023, an estimated 18.2 million people have individual market coverage, the highest since 2016. This represents a significant increase from the approximately 11 million people signed up before the ACA.

The ACA's impact is evident in the declining uninsured rate, which approached an all-time low by the end of 2021. The number of nonelderly uninsured individuals decreased from 27.5 million in 2021 to 25.6 million in 2022, and the uninsured rate dropped from 10.2% in 2021 to a record low of 9.6% in 2022. This trend continued into 2023, with the national uninsured rate reaching a new all-time low of 7.7%.

The success of the ACA can be attributed to various factors, including enhanced subsidies, continuous enrollment conditions, and state Medicaid expansions. The American Rescue Plan Act (ARPA) and the Inflation Reduction Act played a crucial role by providing enhanced subsidies, making insurance more affordable for many. The continuous enrollment condition in Medicaid also contributed to the decline in the uninsured rate, ensuring that more people remained covered.

In addition to federal policies, state-level initiatives have also made a difference. Several states have expanded Medicaid coverage, and some have banned or placed limits on short-term health plans that don't comply with the ACA. These efforts have collectively contributed to the record-low uninsured rate.

The Biden-Harris Administration's commitment to making health insurance accessible and affordable has been a driving force behind these achievements. Their efforts have resulted in historic enrollment numbers, with a record-breaking 16 million Americans enrolling in coverage through HealthCare.gov or state websites during the 2022/2023 Open Enrollment Period.

The decline in the uninsured rate has significant implications for access to healthcare and financial security. Studies show that uninsured individuals are less likely to receive preventive care and services for major health conditions and chronic diseases. Additionally, those without insurance face unaffordable medical bills and are more likely to incur medical debt.

While the ACA has made remarkable progress in expanding coverage and reducing the uninsured rate, there is still work to be done. Efforts to increase outreach, improve enrollment processes, and address disparities in coverage across states and demographic groups will be crucial in ensuring that more people can access the health insurance they need.
