A federal court in Fort Lauderdale certified a nationwide class-action lawsuit seeking damages of about $150 million against two health insurance technology companies based in Tampa.

Attorney Jason Kellogg of Levine Kellogg Lehman Schneider & Grossman in Miami represents the class members, along with Jason Doss of The Doss Firm in Atlanta. They said this litigation shows the potential pitfalls presented for people signing up for health care on the Affordable Care Act marketplace.
