More than 49 million in US covered by ACA over the past decade

NEW YORK, Sept 10 (Reuters) – One in seven Americans have signed up for health insurance coverage through Affordable Care Act marketplaces since their 2014 launch, according to data released on Tuesday by the U.S. Department of the Treasury.

A total of 49.4 million Americans have signed up for the plans, often referred to as Obamacare, with enrollment reaching a high of 20.8 million people in 2024, the agency said.

The insurance plans, run by companies including CVS Health’s Aetna (CVS.N) and UnitedHealth Group (UNH.N) provide income-based subsidies and are sold on the federally-run Healthcare.gov website or are offered directly by states that run their own sites.

Marketplace coverage since 2014 has been higher in states that have not expanded Medicaid programs under the ACA or did so later, the report said.

Typically, people with annual incomes between 100% and 138% of the poverty level – currently set by the government at $15,060 for individuals and $31,200 for a family of four – are covered by the ACA Marketplace in non-expansion states, versus Medicaid in expansion states.
