Pharmacy giant CVS ($CVS) has found itself in the crosshairs of another lawsuit accusing it of inflating the prices of generic drugs. The suit, filed in federal court in San Francisco, says the company pulled off a "massive fraud" through a discount program for patients paying cash for prescriptions, Bloomberg reports. A CVS spokesman told the news service that a similar suit was dismissed in Massachusetts and pointed out that it is health plans, and not CVS, that determine co-pays and how much patients pay. Story
