A federal appeals court has revived a lawsuit against HCA Holdings charging that HCA and three of its Florida hospitals violated Florida’s Deceptive and Unfair Practices Act.

The U.S. Court of Appeals for the Eleventh Circuit’s April 26 ruling overturned a February 2015 federal court decision in the Middle District of Florida that dismissed the class action. That suit accused three HCA hospitals—Memorial Hospital Jacksonville, North Florida Regional Medical Center of Gainesville and JFK Medical Center in Atlantis—of charging unreasonably high fees for emergency radiological services covered by Florida’s Personal Injury Protection (PIP) insurance.

The four Florida residents who filed the complaint received emergency radiological services after motor vehicle accidents. They said they were billed more than other patients who received the same services. “In fact, these fees are up to 65 times higher than the usual and customary fees charged to non-PIP patients for similar radiological services,” according to the complaint.

In one example, the court’s opinion said the hospitals charged between $5,900 and $6,965 for spinal CT scans on the plaintiffs. The ruling said Medicare rates for spinal CT scans are between $213 and $220, and rates for uninsured patients go up to $3,454.

The complaint said the exorbitant rates caused the residents’ $10,000 PIP coverage to be exhausted prematurely. The complaint also accuses HCA of breach of contract as the four Floridians entered into a Condition of Admission contract that required their accounts to be paid at the hospitals’ price lists. All four plaintiffs said they weren’t provided such a price list at the time of their treatments.

Only one of the four plaintiffs was allowed to go forward with a suit against a single hospital in the 2015 ruling by U.S. District Judge James Moody in the Middle District of Florida. Moody’s ruling was overturned by a unanimous Eleventh Circuit panel consisting of Judges Beverly B. Martin, Julie E. Carnes and Senior Judge R. Lanier Anderson III. The suit was originally filed July 2014 in the Southern District of Florida.
