What The Crackdown On Drug Middlemen Means For Your Prescription Costs

If you’ve ever stood at a pharmacy counter bracing for impact – only to be handed a baffling $80 copay for a generic drug that used to cost $10 – you’ve felt the invisible grip of a Pharmacy Benefit Manager (PBM).

While patients juggle soaring out-of-pocket bills and neighborhood drugstores vanish across the country, three massive corporate middlemen quietly dictate 80% of all prescriptions in the U.S. Now, federal regulators are finally forcing them to show their work.

Under a new Department of Labor transparency rule, Healthcare Dive reports that PBMs will have to disclose the hidden markups and backroom manufacturer rebates they pocket at workers’ and employers’ expense. But will pulling back the curtain actually make your medicine affordable?

What is a Pharmacy Benefit Manager (PBM)?

A PBM runs the prescription side of your health plan. Vaishnavi Gudupalli, PharmD, a pharmacist and director of quality, performance improvement and risk at Safe Harbor Recovery Center, explained the role. A PBM “sits between your health plan or employer, the pharmacy and the drugmaker,” she told Blavity Health.

Specifically, PBMs do three main jobs:

• Build the formulary: They decide which drugs your plan covers and at what price tier.
• Negotiate with drugmakers: They work out prices and rebates, which are payments drugmakers make in exchange for favorable coverage.
• Process your claim: They set the pharmacy’s payment and help determine your copay at the register.

As a result, a PBM “shapes what you pay at the counter through your copay, deductible and whether your drug is covered at all,” Gudupalli said.

The industry is also highly concentrated. The “Big Three” PBMs, Express Scripts, CVS Caremark and Optum Rx, handle about 80% of U.S. prescriptions, according to Healthcare Dive.

Breaking down the 2026 PBM transparency and drug pricing rules

Under the final PBM transparency rule, PBMs must disclose their compensation to the self-insured employers that hire them. That includes rebates from drugmakers, payments from pharmacies and money they keep through spread pricing, according to Healthcare Dive.

Notably, PBMs must share this information when they negotiate or renew a contract, and then every six months. In addition, employers can audit the disclosures once a year. PBMs that don’t comply face financial penalties and could have their contracts voided.

The rule takes effect in July 2027. The Labor Department projects it could save employers and workers $22 billion on drug costs over 10 years.

Not everyone supports it, though. The PBM industry argues the rule overlaps with reforms Congress passed earlier this year. Pharmaceutical Care Management Association CEO David Marin called it “a solution in search of a problem.” By contrast, the National Community Pharmacists Association said the rule “creates additional transparency for the first time.”

How new healthcare labor rules will affect prescription costs

The rule targets a practice called spread pricing. Under that model, “a PBM may reimburse the pharmacy one amount and charge the plan a higher amount, keeping the difference,” Gudupalli said. “Disclosure makes that spread visible, which is the first step to curbing it.”

That spread can be huge. For example, Assistant Secretary of Labor Daniel Aronowitz pointed to a drug that cost $5.25 at the pharmacy but was billed to the health plan at $84, or 16 times the cost, according to NCPA.

Because employers pay those bills, hidden markups can also push up the premiums workers pay. With full disclosure, employers can compare PBMs and push for better contracts. Gudupalli noted that some PBMs already use a “pass-through” model, passing negotiated prices and rebates on to the plan and charging a disclosed fee instead.

Will the drug middleman crackdown lower out-of-pocket expenses?

“Not automatically, and not immediately,” Gudupalli said. “Copays and deductibles are set by plan design, and savings from transparency flow through only when the employer’s next contract or plan year reflects them.”

In other words, the PBM transparency rule gives the information to your employer, not to you. “Transparency is a tool for the purchaser, not a direct price cut at the counter,” she said.

Also, the rule covers self-insured employer plans, meaning companies that pay workers’ claims directly. So if your plan is fully insured or you buy coverage on your own, it may not apply. Ask HR which kind of plan you have.

Gudupalli suggests asking your employer a few questions now. For instance, is your PBM contract pass-through or traditional? And will the next contract require full disclosure of rebates, fees and spread pricing?

Why independent pharmacies are fighting PBM practices

Neighborhood pharmacies have felt the squeeze for years. Independent pharmacists say PBMs often reimburse them less than a drug costs and later claw back fees after a prescription is filled.

The result has been a wave of closures. About 1 in 3 U.S. retail pharmacies closed between 2010 and 2021, according to a USC-led study in Health Affairs. Independent pharmacies were more than twice as likely to close as chain stores.

Black neighborhoods were hit hardest. In fact, 37.5% of pharmacies in predominantly Black neighborhoods closed, compared with 27.7% in predominantly white neighborhoods, the researchers found. When a local pharmacy shuts down, people may have to travel farther for medications or skip them altogether.

That’s why independent pharmacists have pushed for PBM reform. The new rule requires PBMs to disclose the money they recoup from pharmacies, which could shed light on clawbacks. Several states have also passed their own limits, and Arkansas has banned PBMs from owning retail pharmacies in the state.

Tips for finding the lowest prices for your prescription medications

You don’t have to wait until 2027 to save. Nicholas Jones, MD, FACS, a double board-certified plastic surgeon in Atlanta who prescribes GLP-1 medications, coaches his patients to ask two questions before the pharmacy runs their claim: “What is the cash price?” and “What is my price with insurance?”

Paying cash often wins “for patients with a high deductible early in the plan year,” Jones told Blavity Health. Still, cash payments may not count toward your deductible, so ask before you decide.

Also, shop around. “Two pharmacies four miles apart can quote very different cash prices on the same prescription, and nobody volunteers that,” Jones said.

Bottom line

The new PBM transparency rule requires drug middlemen to disclose to employers how they are paid, starting in July 2027. It could eventually lower costs, but workers will only see savings if employers use that information to negotiate better deals. In the meantime, compare cash and insurance prices, ask about generics and talk to your pharmacist.
