Three Florida-based medical laboratories suing Cigna Health for $32 million are asking a judge to force the health insurer to hand over patients’ policies, claims and invoices during the discovery process in U.S. District Court in New Haven.

The Florida plaintiffs—BioHealth Laboratories and PB Laboratories, based in West Palm Beach, and Epic Reference Labs in Riviera Beach—say Cigna failed to pay them for authorized blood and urine tests conducted between 2012 and 2017.
