(Chris Rief) The country’s second largest pharmacy chain is the latest party in a class-action lawsuit that accuses CVS of deliberately overcharging hundreds of thousands of patients for generic prescription drugs. Bloomberg reports that the pharmacy customers claim in the class-action seeking lawsuit that CVS intentionally overcharged them for prescription drugs by submitting claims for payment to third parties at inflated prices. According to the lawsuit, since 2008 CVS has engaged in “massive fraud” that led to “substantial ill-gotten gains” by charging three or four times the typical price for generic drugs. At issue in the lawsuit is CVS’s Health Savings Pass, a discount program for patients paying cash for prescriptions.
