CVS sues Tennessee over pharmacy benefit manager monopoly law

CVS Health sued Tennessee after the state passed a law banning pharmacy benefit managers (PBMs) from owning pharmacies, targeting CVS as the only company in Tennessee with both a PBM and physical pharmacies. The law aims to address disparities in drug reimbursement rates between affiliated and non-affiliated pharmacies, with state lawmakers calling it PBM reform. CVS claims the law is unconstitutional and will restrict patient access to medications.
