In February 2026, Senators Elizabeth Warren (D-MA) and Josh Hawley (R-MO) introduced the Break Up Big Medicine Act (S. 3822). The bipartisan legislation, referred to the Senate Judiciary Committee, aims to prohibit pharmacy benefit managers (PBMs), health insurers, and prescription drug or medical device wholesalers from being under common ownership with certain medical service providers or provider groups, including in-patient or outpatient pharmacies.
