UnitedHealth Group is expanding its presence on health exchange marketplaces that were created under the federal Affordable Care Act.
Currently, the Minnetonka-based insurer has about 550,000 customers through health insurance exchanges in 23 states.
Industry reports this spring suggested that many people buying exchange policies have used more care than expected, company officials said Thursday during a conference call with investors.
UnitedHealth Group saw a similar trend during the third quarter and has increased health exchange premiums for next year.
"We expect improved performance next year," said David Wichmann, the company's chief financial officer, during a conference call Thursday to discuss financial results.
"We will expand to 11 new markets in 2016, and we continue to expect exchanges to develop and mature over time into a strong, viable growth market for us," Wichmann said.
UnitedHealth Group is the nation's largest health insurer.
Overall, UnitedHealth posted earnings of $1.6 billion on revenue of $41.5 billion for the third quarter. The profit amounted to $1.65 a share, a penny higher than the consensus forecast of analysts surveyed by Thomson Reuters.
