Pennsylvania Gov. Tom Wolf signed state legislation into law Oct. 28 to require audits of pharmacy benefit managers, which act as middlemen between payers and providers to list drug prices.
The FTC is currently investigating the six largest PBMs — which account for 97 percent of the market — because of their business practices, including "complicated and unclear methods to determine pharmacy reimbursement," according to the FTC.
Pennsylvania joins nearly 20 other states that have introduced legislation aimed at regulating PBMs.
