Oklahoma Attorney General Gentner Drummond is leading a coalition of 45 state attorneys general in calling on the U.S. Department of Labor to implement new rules that would require pharmacy benefit managers (PBMs) to disclose how they set drug prices and generate revenue. The coalition argues that employers and consumers deserve to understand why prescription drug costs are rising.

Why it matters

PBMs play a significant role in the prescription drug market, handling around 80% of all claims nationwide. However, critics say employers often lack visibility into how PBMs determine drug prices and costs. The proposed federal rules aim to increase transparency and allow employers to better audit PBM practices.

The details

The coalition is urging the Department of Labor to require PBMs to report revenue details twice a year and allow employers to audit their pricing practices. The group is also asking federal regulators to clarify that the new rules would not override existing state laws and to coordinate enforcement efforts with state attorneys general. Drummond's office has taken separate action at the state level, including investigations into PBM practices and a $32 million settlement tied to the state employee health plan.

  • The coalition submitted its request to the Department of Labor in April 2026.
