Total enrollment in the individual health insurance market fell in 2018 to 13.8 million, down from a high of 17.4 million in 2015, according to an analysis from the Kaiser Family Foundation.
For its report, KFF studied federal enrollment and administrative data that insurers submit to the National Association of Insurance Commissioners. KFF used the data to measure changes in enrollment in the individual market before and after the ACA's coverage expansions, and after market rules that went into effect in 2014 through the first quarter of this year.
In 2013, before the coverage expansions went into effect, total individual market enrollment was 10.6 million. The decline from its peak in 2015 reflected a decline of enrollment in the off-exchange market, where enrollees don't receive subsidies for insurance and had to face significant premium increases in 2017 and 2018.
For the first quarter of 2019, KFF said enrollment fell 5 percent compared to the first quarter of 2018. The organization said enrollment may stabilize if premium growth continues to level off.
