A federal appeals court will wade into a battle about whether Florida Blue, the state’s largest health insurer, violated antitrust laws by preventing agents from selling policies for a rival insurance company.

Oscar Insurance Company of Florida went to the U.S. Court of Appeals for the Eleventh Circuit after a district judge sided with Florida Blue in the dispute, which is rooted in Oscar’s entrance in 2018 into the market for individual health-insurance policies in the Orlando area.
