Florida hospitals are battling back against a pair of proposed “transparency” rules requiring hospitals and ambulatory surgical centers to provide information to patients and prospective patients about potential costs of treatment.

A statewide group that represents most hospitals filed an administrative challenge last week that maintains the rules go beyond what is authorized by law.

The Florida Hospital Association also maintains the state underestimated the fiscal impact of the proposed rules and contends the rules require legislative approval before implementation because they would increase costs to hospitals and ambulatory surgical centers by more than $1 million over a five-year period.
