Business groups are raising privacy concerns after state regulators requested detailed data on Floridians’ prescription drugs, including patients’ names and dates of birth and their doctors.

The Office of Insurance Regulation is demanding the unusual trove of data from pharmacy benefit managers — health care industry middlemen that Gov. Ron DeSantis and others have blamed for skyrocketing drug prices and monopolistic behavior.

The companies were asked this year to turn over claim reimbursement data for every prescription drug they filled in Florida in 2024, possibly hundreds of millions of transactions.

The state did not answer when asked how many companies have complied. It said it wanted the data to better understand the companies’ practices.
