Overview of health insurance in the US
Health insurance in the US is primarily provided through employer-sponsored plans, individual private insurance, and government programs like Medicare and Medicaid
The US healthcare system is unique among developed countries in its reliance on private insurance and high costs, which has led to significant disparities in access and outcomes based on factors like race, ethnicity, and socioeconomic status
Prior to the Affordable Care Act (ACA), many Americans lacked insurance coverage due to high costs, pre-existing condition exclusions, and limited eligibility for public programs, disproportionately impacting communities of color

1 of 2
Required most individuals to obtain health insurance or pay a penalty, with the goal of expanding the risk pool and making coverage more affordable
Provided exemptions for financial hardship, religious objections, and other factors
Was repealed effective 2019 but many states have implemented their own mandates
Expansion of Medicaid eligibility
Allowed states to expand Medicaid coverage to adults under 65 with income up to 138% of the federal poverty level, with federal funding covering 90% of the costs
As of 2021, 38 states and DC have expanded Medicaid under the ACA
Has significantly increased coverage for low-income adults, particularly in communities of color
Subsidies for purchasing insurance
Provides premium tax credits for individuals and families with incomes between 100-400% of the federal poverty level to purchase coverage on the insurance marketplaces
Also provides cost-sharing reductions to lower out-of-pocket expenses for low-income enrollees
Has made marketplace coverage more affordable but some still find premiums and deductibles too high
Protections for pre-existing conditions
Prohibits insurers from denying coverage, charging higher premiums, or excluding coverage for pre-existing health conditions
Requires coverage of essential health benefits like preventive services, prescription drugs, and mental healthcare
Has improved access to coverage for millions with health conditions but also contributed to higher premiums overall
Impact on racial and ethnic disparities
Changes in uninsured rates by race/ethnicity
The ACA has significantly reduced uninsured rates across all racial and ethnic groups, with the greatest gains among Hispanics, Blacks, and Native Americans
As of 2019, the uninsured rate was 7.9% for non-Hispanic whites, 10.1% for Blacks, 16.7% for Hispanics, and 20.5% for Native Americans, compared to 14.3%, 19.3%, 32.4%, and 30.7% respectively in 2013
Despite progress, disparities persist, in part due to differences in Medicaid expansion, immigration status, and other barriers
Remaining barriers to healthcare access
Even with insurance, many still face barriers like high out-of-pocket costs, limited provider networks, and lack of transportation or paid leave
Disparities in access also stem from structural inequities like residential segregation, language barriers, and implicit bias in healthcare
Addressing these will require targeted outreach, culturally competent care, and policies that tackle social determinants of health
Challenges and controversies
Opposition and legal challenges
The ACA faced strong political opposition and legal challenges, including two major Supreme Court cases that upheld key provisions but struck down mandatory Medicaid expansion
Opponents argue the law is government overreach, while proponents say it has expanded access and consumer protections
Ongoing debate reflects deeper ideological divides over the role of government in healthcare
Sustainability of the insurance marketplaces
Some insurers have exited the ACA marketplaces due to financial losses, leading to fewer plan choices and higher premiums in some areas
Enrollment on the marketplaces has been lower than initially projected, in part due to high costs and the repeal of the individual mandate
Stabilizing the marketplaces will likely require increased , reinsurance programs, and incentives for insurer participation
Affordability of premiums and deductibles
While the ACA has made coverage more affordable for many, some enrollees still struggle with high premiums and deductibles, particularly those just above the subsidy threshold
In 2021, the average benchmark premium for a 40-year-old was 452permonth,whiletheaveragedeductibleforasilverplanwas4,500
Addressing affordability may involve expanding subsidies, capping out-of-pocket costs, and tackling underlying healthcare costs
Potential future reforms
Proposals for universal healthcare
Some advocates argue the US should transition to a universal healthcare system like "Medicare for All" that would provide comprehensive coverage to all Americans
Proponents say this would reduce costs, improve outcomes, and address disparities, while critics raise concerns about government control, tax increases, and impacts on private insurance
Other proposals include a , lowering the Medicare eligibility age, or allowing people to buy into Medicaid
Role of states in shaping health policy
States have significant flexibility in implementing the ACA, from running their own marketplaces to expanding Medicaid
Some states have gone beyond the ACA with additional subsidies, reinsurance programs, or coverage expansions, while others have sought waivers to scale back provisions
Future reforms may give states even more leeway to innovate, though this could also exacerbate geographic disparities
Addressing social determinants of health
Recognizing that health is shaped by factors like income, education, housing, and discrimination, some argue that healthcare reform must be coupled with broader efforts to address social determinants
This could include investments in early childhood, education, job training, affordable housing, and community development, as well as more integrated models of health and social services
Addressing social determinants is key to advancing and will require collaboration across sectors and levels of government
