Pharmacy Benefits and PBM Contracting

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.

Host, Bridgette Keller is joined by Associate, David Gilboa to break down the highlights from our Spring 2025 PBM Policy and Legislative Update. In just five minutes, we cover the most impactful federal and state developments shaping the PBM landscape this season.

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.

On February 15, 2024, the Centers for Medicare and Medicaid Services (CMS) released the Medicare Prescription Payment Plan Draft Part Two Guidance (Part Two Guidance) as part of the Inflation Reduction Act’s (IRA) efforts to tackle high prescription drug costs. The Medicare Prescription Payment Part Plan (the Program), which was previously referred to as the “OOP Smoothing Program”, was established as part of the IRA and requires Part D plans (PDPs) to offer their members an option to pay for out-of-pocket (OOP) prescription drug costs in monthly capped payments, as opposed to all at once, at a pharmacy. Meaning, for members who opt-in to the Program, they will pay $0 at the pharmacy and the PDP must pay the pharmacy the full cost-sharing amount of the drug and then bill the member the amount of the cost-sharing over the remainder of the calendar year.
