Florida Attorney General Sues Express Scripts and Prime Therapeutics Over Alleged Price Fixing

Florida's attorney general has filed a lawsuit against two of the country's largest pharmacy benefit managers, Express Scripts and Prime Therapeutics, alleging that a business arrangement between the two companies depressed reimbursement rates paid to pharmacies across the state. The filing was reported by Healthcare Dive on August 31, 2026, based on a new complaint. A pharmacy benefit manager, or PBM, is a company that administers prescription drug benefits on behalf of insurers, employers, and Medicare plans, negotiating manufacturer rebates and setting the rates pharmacies are paid for filling prescriptions. This lawsuit is the latest in a growing string of legal and regulatory actions targeting the PBM industry, which has faced scrutiny from state attorneys general, federal agencies, and Congress over how pricing and rebate arrangements are structured.

According to the complaint, the arrangement between Express Scripts and Prime Therapeutics reduced the reimbursement pharmacies received for dispensing medications in Florida, and the attorney general's office characterizes this as anticompetitive conduct. These are allegations made in a civil filing, not conclusions reached by a court or regulator, and the case has not been decided. The reporting reviewed for this article did not include a public response from Express Scripts or Prime Therapeutics; both companies will have the opportunity to respond as the case proceeds through the legal system. Readers can review the original report from Healthcare Dive for further detail on the complaint.

Key Takeaway

This is a civil lawsuit built on allegations, not a proven finding of wrongdoing by either company. Still, seniors enrolled in Medicare Part D or a Medicare Advantage plan with drug coverage should pay attention, because PBM pricing arrangements directly shape pharmacy networks, drug costs, and whether a local pharmacy stays open.

What This Means for Medicare Enrollees

Most people enrolled in Medicare Part D or a Medicare Advantage plan with drug coverage interact with a PBM every time they fill a prescription, even though they rarely see the PBM's name on a bill or card. PBMs sit between drug manufacturers, insurers, and pharmacies, and the rates they negotiate help determine both what a plan pays a pharmacy and, indirectly, what a beneficiary pays at the counter. When pharmacy reimbursement rates are reduced, as alleged in this case, independent and community pharmacies can face significant financial pressure. Over time, that pressure can contribute to reduced hours or closures, which matters most in rural or underserved areas where a single independent pharmacy may be the only convenient option for seniors managing multiple prescriptions.

This lawsuit fits into a broader, ongoing pattern rather than an isolated event. Multiple states and federal agencies have examined PBM business practices in recent years, and this case adds to that trend of increasing legal and regulatory attention on how PBM arrangements affect pricing and pharmacy compensation. For Medicare beneficiaries, the practical concern is less about how this specific lawsuit is ultimately resolved and more about what the broader pattern signals: continued pressure on pharmacy reimbursement can eventually show up as network changes, shifts in which pharmacies carry "preferred" status, or adjustments to out-of-pocket drug costs when plans are redesigned for the following year.

Practical Steps for Seniors Comparing Plans

Readers don't need to track the outcome of this specific lawsuit to protect themselves, but a few habits can help limit exposure to PBM-related pricing shifts over time:

Check your pharmacy network every year. During Medicare's Annual Election Period (October 15 through December 7), confirm your regular pharmacy is still in-network and still holds "preferred" status, since preferred pharmacies typically carry lower copays than standard network pharmacies.
Ask locally if reimbursement issues surface. If a trusted pharmacy mentions reduced reimbursement rates or discusses leaving a plan's network, ask what that could mean for your prescriptions and whether other in-network pharmacies are nearby.
Compare total drug costs, not just premiums. Two plans with similar monthly premiums can have very different formularies and pharmacy pricing tiers. Use Medicare's Plan Finder tool or speak with a licensed insurance agent to compare actual expected costs for your specific medications.
Treat litigation news as a signal, not a verdict. Lawsuits against PBMs can take months or years to resolve and may be amended, dismissed, or settled well before any court ruling. This filing is one data point in an evolving regulatory picture rather than a reason to change coverage immediately.

Senior Plan Path will continue following PBM litigation and regulatory developments as they affect Medicare drug coverage. For now, this case is a reminder that the middlemen behind prescription pricing can have a real, if largely invisible, effect on the pharmacies and costs seniors depend on each year.
