The U.S. Federal Trade Commission sued the country's three largest pharmacy benefit managers on Friday, accusing them of steering diabetes patients toward higher-priced insulin to reap millions of dollars in rebates from pharmaceutical companies.
The case accuses UnitedHealth Group Inc's Optum unit, CVS Health Corp's CVS Caremark and Cigna Corp's Express Scripts of unfairly excluding lower-cost insulin products from lists of drugs covered by insurers.
