Wegovy and Ozempic are weight reduction medicine that promise to remodel the remedy of weight problems, coronary heart illness and different persistent situations that afflict hundreds of thousands of Individuals. However whereas everybody agrees these medicine have the potential to remodel lives, nobody can agree on how greatest to pay for them.
Wegovy sells for a listing worth – or worth earlier than reductions – of $1,349 per 30 days within the U.S. The identical drug lists for $265 in Canada and fewer than half of that within the U.Okay. These dramatic variations illustrate a bigger concern: The checklist worth of patented medicine within the U.S. are far larger than in different wealthy international locations.
U.S. Sen. Bernie Sanders spoke for a lot of Individuals when he mentioned the excessive value of medicine in America was “not just an issue of economics” however somewhat “a profound moral issue.”
Ethical outrage results in a seek for villains. Joe Kernan, host of CNBC’s enterprise present “Squawk Box,” minimize to the chase when he requested: “Who is screwing us here? The PBMs? The drugmakers?”
As a well being economist who writes about improvements within the well being sector, I’ve spent a very good portion of the previous 5 years desirous about these questions. What I’ve discovered is that top checklist costs for medicine don’t inform us a lot about who’s screwing whom. To actually perceive the issue of drug pricing within the U.S., you’ll want to begin with the difficult economics of the PBMs, or pharmacy profit managers.
What are pharmacy profit managers?
Pharmacy profit managers began popping up within the late Nineteen Sixties as suppliers of claims processing and administrative providers for well being insurers. Over time, they turned important middlemen between drugmakers and the numerous insurers, employers and authorities entities who buy medicine on behalf of their members, constituents and beneficiaries.
Mergers between PBMs have led to a market dominated by a small variety of very giant gamers. In 2023, the three greatest ones – OptumRx, Categorical Scripts and CVS Caremark – managed 79% of U.S. prescription claims and served roughly 270 million clients.
The first position of those corporations is to barter worth, affordability and entry to pharmaceuticals. They do that by working and designing formularies, that are lists of medicine that insurers cowl.

Formularies additionally assign medicine to completely different tiers that decide what sufferers should pay out of pocket to entry the drug. Generic medicine are sometimes positioned within the tier with the bottom out-of-pocket prices. Patented medicine that insurers desire are positioned in a tier with larger prices, and nonpreferred medicine are in a tier that requires sufferers to pay much more. Some medicine may even be excluded from the formulary altogether, that means insurance coverage gained’t cowl them.
Tier placement determines how inexpensive a drugs is to shoppers and the efficient drug worth that insurers pay. Drugmakers compete with one another for placement on desired formulary tiers by providing PBMs vital reductions off their checklist worth. The value at which the PBM obtains the drug for its shoppers is the online worth – the checklist worth minus the drugmaker’s low cost.
If a drugmaker will increase its rebate, the online worth falls, even when the publicly posted checklist costs stay excessive. For this reason specializing in checklist costs to find out the price of a drug might be deceptive.
The value is correct?
Record costs for medicine are public information, however drugmakers’ reductions to PBMs are carefully held secrets and techniques. Consequently, it’s onerous to know precisely how a lot insurers pay for many pharmaceuticals.
This secrecy raises difficult questions. Do PBMs use their measurement and negotiating energy to win decrease web costs from drugmakers? Or do PBMs use their dominant market place and opaque enterprise practices to counterpoint themselves on the expense of their clients and the remainder of society?
The reply to each these questions is, surprisingly, sure. If the competition for formulary placement works because it ought to, competitors compels drugmakers to supply substantial reductions off the revealed checklist worth. Consequently, insurers and shoppers profit from a lowered web worth for medicine. Nevertheless, formulary competitors might be undermined in numerous methods.
In a 2024 report, for instance, the U.S. Federal Commerce Fee discovered proof that the producer of a patented type of insulin provided larger rebates to a PBM if competing insulins have been positioned on a much less favorable tier of a formulary or excluded altogether. This association reduces shopper selection. If a less expensive generic equal is excluded, the association would additionally favor a costlier drug that raises affected person prices. Widespread use of such exclusionary rebates would possibly even discourage new generics and scale back competitors.
Introducing biosimilar medicine manufactured particularly for PBMs to substitute for costly biologics manufactured elsewhere may also undermine formulary competitors. When PBMs favor their in-house merchandise in formularies, this reduces the motivation for different drugmakers to introduce competing merchandise. The result’s each much less competitors and better costs.
Competitors throughout the formulary can be distorted when drugmakers put up very excessive checklist costs. This artificially inflates rebates for PBMs with out decreasing web costs for insurers and different events. Inflated checklist costs additionally improve the price of medicine for some teams of sufferers – notably, individuals who lack medical health insurance or have excessive deductible plans.
Market competitors
Simply as truthful competitors can break down throughout the PBM’s formulary, it could additionally crumble out there for PBM providers.
The present regulatory atmosphere within the U.S. tolerates overly giant PBMs that have interaction in anticompetitive practices to build up extreme income. With out sturdy rivals, dominant PBMs are free to cost their clients excessive charges and preserve a bigger portion of drugmaker rebates for themselves.
In principle, this downside needs to be self-correcting. Excessive income ought to entice new rivals into the business. Competitors from these entrants ought to decrease charges and scale back the fraction of rebates these corporations preserve. Nevertheless, issues work out in a different way in follow as a result of the biggest PBMs have merged with the biggest well being insurers. CVS has merged with Aetna. Categorical Scripts and OptumRx merged, respectively, with Cigna and UnitedHealthcare. These combos scale back the variety of potential clients for brand new PBMs and so preserve new rivals from getting into the market.

Scrappy upstarts that might shake up the established order additionally discover themselves at a drawback attributable to widespread contracting practices. Giant PBMs, for instance, typically insist on “most-favored-nation” contracts that require drugmakers to fulfill or beat the costs they provide to different consumers. These contracts remove the aggressive benefit a brand new PBM would possibly acquire from acquiring higher costs than incumbent corporations.
There may be rising concern amongst specialists that dominant PBMs additionally use formularies to steer worthwhile “specialty prescriptions” to pharmacies with whom they’re affiliated. The pharmacies affiliated with the three greatest PBMs expanded their share of the specialty drug market from 55% to 67% between 2016 and 2023. Issues over such anticompetitive practices have led to bipartisan laws to power PBMs to dump their retail or mail-order pharmacies.
Who’re the villains?
So, are PBMs screwing us? If we didn’t have PBMs, we would want to invent them – or one thing like them – to acquire cheap costs on patented medicine. However the focus of market energy amongst a number of corporations threatens to dissipate the worth they create.
Rising competitors throughout the PBM market will doubtless require a bigger variety of smaller PBMs, and huge insurers may additionally be required to divest their PBM items.
Opposite to traditional knowledge, smaller PBMs will doubtless be simply as capable of negotiate a low web worth for Wegovy and different patented medicine as bigger PBMs. Past a sure minimal scale, it’s competitors for formulary placement, not PBM measurement, that issues. A extra aggressive and clear marketplace for PBM providers will assist preserve that contest truthful and clear – to the advantage of clients and society.
In that sense, PBMs aren’t the villain. An excessive amount of market energy in too few palms is the issue, and that’s one thing extra competitors, smart regulation and vocal shoppers would possibly repair.
