The CVS Caremark pharmacy benefit manager improperly reported generic drug prices to the federal government, causing Medicare and its beneficiaries to overpay for medicines, while pocketing a difference in pricing, according to a lawsuit filed by an actuary at the Aetna health insurer.
The lawsuit revolves around complicated, behind-the-scenes contracts between pharmacy benefit managers and Medicare Part D plans, and the pricing that must be reported to the Centers for Medicare and Medicaid Services.
