The Affordable Care Act (ACA) requires health insurance plans to cover certain essential health benefits, which critics argue has driven up premium costs. However, evidence on the impact of these mandated benefits is mixed, with some experts saying other ACA provisions like requiring insurers to accept all applicants regardless of health status have also played a role in premium increases. The debate over the ACA's impact on healthcare costs continues, with the Trump administration proposing changes to make high-deductible plans more accessible.

Why it matters

The debate over the ACA's impact on healthcare costs is politically charged, with Republicans blaming the law's mandated benefits for premium hikes and Democrats pushing back. This issue is likely to be a key point of contention in the upcoming elections, as the affordability of healthcare coverage remains a top concern for many Americans.

The details

The ACA requires health plans to cover 10 categories of essential health benefits, including emergency services, hospitalization, and prescription drugs. Critics argue this mandate has driven up premium costs, but the evidence is mixed. While ACA premiums have increased more than employer-based coverage in recent years, premiums were already rising before the ACA took effect. Additionally, states that previously required similar coverage saw less dramatic premium increases after the ACA was implemented. Experts say other ACA provisions, like requiring insurers to accept all applicants regardless of health status, have also contributed to premium hikes. The Trump administration has proposed making high-deductible 'catastrophic' plans more accessible, arguing this will lower premiums, but it's unclear how popular such plans would be.

  • In January 2026, President Donald Trump unveiled a plan to address healthcare spending, criticizing the ACA's role in driving up costs.
  • In the 2026 State of the Union address, Trump again blamed the 'crushing cost of health care' on the Affordable Care Act.
  • Late last year, the enhanced tax subsidies that had lowered the cost of ACA insurance for millions of Americans expired, thrusting the issue of ACA-related costs back to center stage.

What they’re saying

“I call it the unaffordable care act.”

— Donald Trump (State of the Union address)

“Premiums 'skyrocketed across the country since it took effect.'”

— Mike Lawler, Republican Congressman (KFF Health News)

“The ACA faces 'underlying inflationary pressures' — including the now-expired, more generous, covid pandemic-era subsidies — that affect its policyholders more so than employer plans.”

— Brian Blase, President, Paragon Health Institute (KFF Health News)

“It was a combination of things.”

— Edmund Haislmaier, Senior Research Fellow, Heritage Foundation (KFF Health News)

“If you look down the list of essential health benefits, I think most people would reach the judgment that those are health care services that people should have access to.”

— Larry Levitt, Executive Vice President for Health Policy, KFF (KFF Health News)

What’s next

The Trump administration has proposed a regulatory plan for 2027 that would raise deductibles for catastrophic ACA plans, in an effort to lower premiums and expand coverage choices. However, it remains to be seen how popular such high-deductible plans would be.

The takeaway

The debate over the ACA's impact on healthcare costs is ongoing, with valid arguments on both sides. While the law's mandated essential health benefits have likely contributed to premium increases, other ACA provisions and pre-existing market trends have also played a role. As policymakers continue to grapple with healthcare affordability, finding the right balance between coverage requirements and consumer costs will be crucial.
