NEW YORK, Oct 14 (Reuters) – Affordable Care Act enrollment fell by 18% to 20.5 million members in June, according to ​health policy research firm KFF, marking the ‌steepest annual decline since 2015 as Americans struggle with rising health insurance costs.

Enrollment was 25.2 million in the year-earlier period, KFF said.

The 2010 Affordable Care Act, passed under Democratic ‌President ​Barack Obama, created income-based government-subsidized health ⁠plans for individuals, commonly ⁠known as Obamacare. Millions have dropped coverage this year after extra COVID-19 pandemic subsidies expired, doubling or even tripling costs for some people.

A previous KFF ​study found enrollment declined 12% year-over-year in February.

US Health and Human Services Secretary Robert F. ⁠Kennedy Jr. also said in ⁠a Wednesday press briefing that about ​20 million people currently rely on Obamacare.

KFF said plan ​members are expected to continue falling off the ‌rolls through 2026. Some 17% of members enrolled in Obamacare plans say they are not confident they can pay premiums through the year, according ⁠to a KFF March survey.

Insurers such as Centene and UnitedHealth have flagged rising medical costs in their Obamacare businesses this ⁠year. Companies ‌offering the plans asked for a ⁠median rate hike of 14% this ​year, the ‌second-highest increase for premiums in nearly ​a decade.

Insurers ⁠asking for higher payments pointed to a sicker or higher-risk mix of patients enrolled in the plans.

KFF’s study analyzed insurer marketplace enrollment reported in regulatory filings.
