Massive companies managing prescriptions for millions of Americans will soon need to disclose detailed financial information. This is due to new regulations from the Trump administration. Pharmacy benefit managers will now have to reveal how much they pay for drugs and what they receive from drug manufacturers. This rule, announced by the Labor Department, aims to lower drug costs and increase transparency in the healthcare system.
Labor Secretary Keith Sonderling stated, “The Trump administration is ensuring no one in the healthcare industry can escape the competition that comes from complete price transparency.” The regulation will enable employers to secure better deals and reduce drug prices for over 72 million Americans on self-insured group healthcare plans.
Advocates and lawmakers have critiqued pharmacy benefit managers for directing patients to more expensive drugs due to a lack of transparency. The regulation has faced opposition from major players such as Express Scripts, Caremark, and Optum Rx, which control about 80% of U.S. prescription drug claims. Implementation begins in July.
The Cigna Group’s Express Scripts, CVS’s Caremark, and UnitedHealth Group’s Optum Rx manage most prescription drug claims, according to a 2026 report by the Groundwork Collaborative.
