Consumer Premium Contributions to Increase $3,300 on Average in 2015 if Supreme Court Rules for King; 6.4 Million Current Enrollees Could Be Impacted by Loss of Subsidies

Consumers could face average annual premium contribution increases of $3,300 in 2015, if the Supreme Court rules tax credits are illegal in states with a federal exchange, according to new analysis from Avalere.1

The Supreme Court is expected to rule imminently on whether 6.4 million Americans can continue to receive tax credit subsidies through federal exchanges in 34 states. Florida and Texas would have the most number of state residents impacted by the ruling—1.3 million and 0.8 million respectively (see Table 1).

“Exchange enrollees are currently subsidized at a very high rate,” said Elizabeth Carpenter, director at Avalere. “As a result, many individuals would likely find exchange premiums unaffordable without the tax credits provided under the law. If the Court rules for King, many current enrollees are expected to drop coverage.”

In 2015, 85 percent of enrollees in federal exchange states receive a tax credit subsidy. On average, these enrollees are subsidized at a rate of $3,300 for the year. However, subsidies vary by income and the premiums in a given geography. As a result, premium contribution increases stemming from the Supreme Court ruling would vary by state, ranging from $6,400 average in Alaska, to a $1,900 in Arizona (see Table 1). These estimates reflect only the loss of subsidies in 2015 based on current premiums in the market. 2 If the Supreme Court ruling results in many exchange enrollees dropping coverage, it could materially impact the risk-pool in both 2015 and future years.3 Some states have already permitted exchange plans to file two sets of rates for 2016, contingent on the Supreme Court ruling, while others have indicated that plans may be able to refile following the verdict.4  

“We can’t assume that consumers will simply be able to return to previous sources of coverage if subsidies are struck down,” said Dan Mendelson, CEO at Avalere. “The ACA has fundamentally shifted the insurance market, and the elimination of subsidies would mean the vast majority of those adversely affected will struggle to maintain access to care.”

Indeed, many exchange consumers will not only find it difficult to continue to afford insurance without subsidies, others will likely be unable to return to their previous source of coverage. A recent survey by the Rand Corporation estimated the previous source of coverage for exchange enrollees as of February 2015.5 

After applying these findings to the population potentially impacted by the Supreme Court ruling, Avalere estimates approximately 2.3 million exchange enrollees – 37 percent of those enrolled – were likely to be uninsured before enrolling in exchange coverage. These consumers are unlikely to continue purchasing coverage without subsidies. 

Another 32 percent of those affected by the ruling—about 2 million enrollees—transitioned to marketplace coverage from employer-sponsored insurance. While some of these employees may be able to rejoin their employer-sponsored insurance plan, reports from insurance companies indicate that many small employers may have stopped offering coverage after exchanges launched in 2014. 

Finally, 14 percent or almost 1 million exchange enrollees joined the market from non-group insurance offered prior to the establishment of exchanges. While this market is still in place, the introduction of insurance market reforms, essential health benefits, and patient protections mean that much of the coverage these individuals previously purchased may be unavailable or available at increased cost. 

“If the Court rules against the subsidies, Congress, the Administration, and the states will face immense pressure to take action,” said Caroline Pearson, senior vice president at Avalere.  “While some stakeholders may advocate for a short-term fix, others may see the ruling as an opportunity to reform the Affordable Care Act more broadly.”


Analysis assumes consumers do not switch plans following the ruling and that 2015 plan premiums remain at current levels. Loss of subsidies will be considered a qualifying event for a special enrollment period, and therefore consumers would have the option to select a less-expensive plan. However, carriers in the FFE may be permitted to terminate contracts with the exchange under certain scenarios, which could reduce coverage offerings.

While Nevada, New Mexico, and Oregon all rely on HealthCare.gov infrastructure in 2015, Avalere considers them state-based exchanges for the purposes of this analysis. 

Using the RAND study, Avalere applies the RAND study to the subsidy eligible population to determine previous source of insurance. For the purpose of this analysis, Avalere assumes that the whole market distribution studied by RAND is similar to the distribution of subsidized enrollees. 

Premium increases and the number of individuals who will be impacted by the ruling are based on “March 31, 2015 Effectuated Enrollment Snapshot,” Centers for Medicare & Medicaid Services, June 2, 2015.
