On May 12, 2025, the Centers for Medicare & Medicaid Services (CMS) issued draft guidance for the third cycle of the IRA’s Medicare Drug Price Negotiation Program (Negotiation Program).

CMS finalizes 2026 Medicare Part D changes under the IRA, including new cost limits, subsidy guidance, and updated creditable coverage rules.

GLP-1 receptor agonists (GLP-1s) such as semaglutide, and dual agonists like tirzepatide, are transforming obesity treatment and reshaping the US health care landscape.

In a significant legal development, a federal judge has temporarily blocked Arkansas from enforcing Act 624. Act 624 prohibits pharmacy benefit managers (PBMs) from owning or operating pharmacies in the state, effectively forcing vertically integrated companies to divest or shut down their Arkansas pharmacy operations. However, on July 28, 2025, U.S. District Judge Brian Miller granted a preliminary injunction to several major PBMs and affiliated entities, halting the law’s implementation pending final resolution of the case.

The PBM Policy and Legislative Update — Spring 2025 edition builds upon prior issues and summarizes activity from January through March (2025) that affects the PBM industry. It highlights federal activities, state activities, and other noteworthy events and trends affecting the PBM industry.

On April 16, 2025, Arkansas enacted Act 624 (the Act), an unprecedented law prohibiting pharmacy benefit managers (PBMs) from owning or operating pharmacies in the state. As we discussed in our May 2025 blog post, the law’s passage has already resulted in market disruptions, and PBMs with vertically integrated business models have cautioned that the law will limit patients’ access to drugs and cost many local jobs. 

Now, two of the nation’s largest PBMs, CVS Health and Cigna’s Express Scripts (ESI), have filed federal lawsuits seeking to block implementation of the Act on the grounds that the Act is unconstitutional, preempted by federal law, and harmful to Arkansans. 

Arkansas Governor signed Act 624 on April 16, 2025, banning PBMs from acquiring or holding a direct or indirect interest in a pharmacy. This state-led move may inspire similar laws elsewhere.

On April 15, 2025, President Trump issued an Executive Order instructing federal agencies to implement a variety of drug pricing reforms. The Executive Order addresses drug pricing from several different angles, including pharmacy benefit manager (“PBM”) competition and transparency, Medicare and Medicaid drug pricing, international importation, and drug manufacturer competition (the “Executive Order”).

The Executive Order, which is the first significant action taken by the current Administration to address drug prices, echoes initiatives and policy statements announced during the first Trump Administration. However, most of the drug pricing reforms announced during the first Administration were never fully implemented. It is unclear how many of the proposals in this Executive Order will ultimately be implemented, but it does provide the clearest outline yet of the Administration’s policy priorities regarding drug prices.
