Aetna has announced it will reduce its individual public exchange participation in the upcoming year, but plans to maintain an on-exchange presence in Delaware, Iowa, Nebraska and Virginia.

The company, focusing on the Affordable Care Act’s individual public exchanges, will reduce the participation from 778 to 242 counties in 2017. Aetna will continue to provide an off-exchange product option for 2017 to consumers in the vast majority of counties in which it offered the public exchange products in 2016.

“Following a thorough business review and in light of a second-quarter pretax loss of $200 million and total pretax losses of more than $430 million since January 2014 in our individual products, we have decided to reduce our individual public exchange presence in 2017, which will limit our financial exposure moving forward,” Mark T. Bertolini, Aetna chairman and CEO, said in a statement. “More than 40 payers of various sizes have similarly chosen to stop selling plans in one or more rating areas in the individual public exchanges over the 2015 and 2016 plan years, collectively exiting hundreds of rating areas in more than 30 states. As a strong supporter of public exchanges as a means to meet the needs of the uninsured, we regret having to make this decision.”

The announcement does not affect any of the company’s products or services for this year, he said.
