A new law in Tennessee bans pharmacy benefit managers (PBMs) from owning pharmacies, prompting lawsuits from several major PBMs, including CVS and Express Scripts. The law was recently signed by the governor after being passed by lawmakers. Multiple outlets report that the lawsuits aim to block the law, which some describe as breaking up PBMs and pharmacies, although details of the law and the lawsuits' chances of success are not specified.
