Obama Administration Defends Affordable Care Act Subsidy Structure

In a heated exchange over healthcare policy, Republican Sen. Ron Johnson and independent Sen. Bernie Sanders have clashed over the potential impact of expiring Affordable Care Act subsidies, highlighting the political tensions surrounding healthcare costs as a key deadline approaches.

Johnson took to social media to challenge Sanders’ claim that “over 20 million Americans” would see their healthcare premiums double if enhanced ACA subsidies expire at year’s end. Johnson declared Sanders “simply wrong” and invited fact-checkers to weigh in on the dispute.

Analysis shows that while Sanders overstated the case, Johnson’s response also omitted critical context. According to the nonpartisan Kaiser Family Foundation (KFF), out-of-pocket premiums for ACA subsidy recipients would increase by 114% on average – more than doubling – but not uniformly for all enrollees as Sanders suggested.

“On average, 22 million people will see their premium payments double. Some will see them more than double. Some will see them less than double, because that is the nature of an average,” explained Cynthia Cox, KFF vice president and director of the Program on the ACA.

Sanders’ office acknowledged that he meant the doubling was an average effect. The Vermont senator had correctly noted in his floor remarks that some enrollees could face “a tripling or a quadrupling” of costs, particularly those in their 60s earning just above subsidy thresholds.

The dispute centers on enhanced subsidies implemented during the pandemic and later extended through 2025. These subsidies increased financial assistance by lowering the percentage of income people must pay toward premiums and eliminated the income cap previously set at 400% of the federal poverty level.

Johnson argued that “22 of the 24 million Americans on Obamacare exchanges will continue receiving Obamacare subsidies as originally designed” and that “the dollar amount of those subsidies will likely increase, not decrease.” While technically accurate, this statement omits that enrollees would still pay significantly more out-of-pocket if the enhanced subsidies expire.

“It’s possible to both get a larger tax credit and still pay more out of your own pocket, much more out of your own pocket,” Cox noted. “Pretty much everyone who buys their own insurance will see an increase in what they have to pay.”

The impact varies widely based on income levels. Many low-income enrollees currently paying nothing for coverage would face new premiums if enhancements expire. Nearly 6.7 million enrollees – 39% of those on the federal HealthCare.gov – selected plans with zero-dollar premiums.

Johnson correctly pointed out that about 1.6 million people with incomes above 400% of poverty would lose subsidies entirely, as they’re only eligible under the enhancement program.

The dispute comes as ACA premiums are already projected to rise significantly. Total premiums charged by insurers for ACA plans are increasing by 26% on average for 2026, according to KFF. Multiple factors drive this increase, including rising hospital costs, expensive GLP-1 drugs like Ozempic, potential tariffs, and insurers’ anticipation that healthier people might drop coverage if enhanced subsidies expire.

The Congressional Budget Office estimates that 4.2 million more people will lack health insurance by 2034 if the enhanced subsidies expire, while the Urban Institute projects 4.8 million more uninsured next year.

The debate over ACA subsidies has become particularly urgent following recent congressional action. Democrats attempted to include an extension of these enhanced subsidies in legislation to continue government funding, but Republicans rejected the proposal. Under a Senate deal that ended this month’s government shutdown, lawmakers will hold a December vote on the fate of these boosted subsidies.
