Some people with health insurance under Obamacare will lose their plans next year.
AETNA said it is pulling out of the health exchanges set up by the Affordable Care Act in 11 of the 15 states where it currently operates.
The company reports it lost $430 million in its individual health care policies since the exchange opened in January 2014.
AETNA will only sell Obamacare products in Delaware, Iowa, Nebraska and Virginia.
The move follows similar moves by competitors such as UnitedHealth Group, the nation’s largest insurer. It is expected to exit Obamacare exchanges in 2017.
