Separate lawsuits allege that both CVS and Walgreens charged insured customers more for generics than they would pay if they didn’t use their insurance.

NBC News reports that CVS Health Corporation is being charged with participating in a “fraudulent scheme,” in which the plaintiff, Megan Schultz, paid $165.68 for a prescription in July that would have cost $92 if she hadn’t used her insurance to pay for it.

And the Chicago Tribune reports that David Grabstald has filed a proposed class-action suit against Walgreens Boots Alliance accusing the Illinois pharmacy of “fraudulently overcharging many customers for generic drugs.”
