Wegovy and Ozempic are weight reduction medicine that promise to remodel the remedy of weight problems, coronary heart illness and different continual situations that afflict tens of millions of Individuals. However whereas everybody agrees these medicine have the potential to rework lives, nobody can agree on how greatest to pay for them.
Wegovy sells for a record worth – or worth earlier than reductions – of $1,349 monthly within the U.S. The identical drug lists for $265 in Canada and fewer than half of that within the U.Ok. These dramatic variations illustrate a bigger challenge: The record worth of patented medicine within the U.S. are far larger than in different wealthy international locations.
U.S. Sen. Bernie Sanders spoke for many Individuals when he mentioned the excessive value of medication in America was “not simply a difficulty of economics” however quite “a profound ethical challenge.”
Ethical outrage results in a seek for villains. Joe Kernan, host of CNBC’s enterprise present “Squawk Field,” reduce to the chase when he requested: “Who’s screwing us right here? The PBMs? The drugmakers?”
As a well being economist who writes about improvements within the well being sector, I’ve spent an excellent portion of the previous 5 years serious about these questions. What I’ve realized is that prime record 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., that you must 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 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 massive gamers. In 2023, the three greatest ones – OptumRx, Specific Scripts and CVS Caremark – managed 79% of U.S. prescription claims and served roughly 270 million clients.
The first position of those firms is to barter worth, affordability and entry to prescribed drugs. They do that by working and designing formularies, that are lists of medication that insurers cowl.

Formularies additionally assign medicine to totally different tiers that decide what sufferers should pay out of pocket to entry the drug. Generic medicine are usually positioned within the tier with the bottom out-of-pocket prices. Patented medicine that insurers want 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 received’t cowl them.
Tier placement determines how reasonably priced a drugs is to customers 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 record worth. The value at which the PBM obtains the drug for its purchasers is the online worth – the record worth minus the drugmaker’s low cost.
If a drugmaker will increase its rebate, the online worth falls, even when the publicly posted record costs stay excessive. For this reason specializing in record costs to find out the price of a drug could be deceptive.
The value is true?
Checklist costs for medicine are public information, however drugmakers’ reductions to PBMs are intently held secrets and techniques. Consequently, it’s arduous to know precisely how a lot insurers pay for many prescribed drugs.
This secrecy raises difficult questions. Do PBMs use their dimension 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 printed record worth. Consequently, insurers and customers profit from a lowered web worth for medicine. Nevertheless, formulary competitors could 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 had been positioned on a much less favorable tier of a formulary or excluded altogether. This association reduces client alternative. 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 inside the formulary will also be distorted when drugmakers publish very excessive record costs. This artificially inflates rebates for PBMs with out decreasing web costs for insurers and different events. Inflated record costs additionally improve the price of medicine for some teams of sufferers – notably, individuals who lack medical insurance or have excessive deductible plans.
Market competitors
Simply as honest competitors can break down inside the PBM’s formulary, it will possibly additionally disintegrate out there for PBM providers.
The present regulatory atmosphere within the U.S. tolerates overly massive PBMs that interact in anticompetitive practices to build up extreme income. With out sturdy opponents, dominant PBMs are free to cost their clients excessive charges and preserve a bigger portion of drugmaker rebates for themselves.
In concept, this drawback must be self-correcting. Excessive income ought to appeal to new opponents into the trade. Competitors from these entrants ought to decrease charges and scale back the fraction of rebates these firms preserve. Nevertheless, issues work out in a different way in observe as a result of the most important PBMs have merged with the most important well being insurers. CVS has merged with Aetna. Specific 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 opponents from getting into the market.

Scrappy upstarts that might shake up the established order additionally discover themselves at an obstacle resulting from widespread contracting practices. Massive PBMs, for instance, typically insist on “most-favored-nation” contracts that require drugmakers to satisfy or beat the costs they provide to different patrons. These contracts eradicate the aggressive benefit a brand new PBM would possibly achieve from acquiring higher costs than incumbent firms.
There may be rising concern amongst consultants 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. Considerations over such anticompetitive practices have led to bipartisan laws to pressure PBMs to unload 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 affordable costs on patented medicine. However the focus of market energy amongst a number of firms threatens to dissipate the worth they create.
Rising competitors inside the PBM market will probably require a bigger variety of smaller PBMs, and enormous insurers can also be required to divest their PBM models.
Opposite to standard knowledge, smaller PBMs will probably 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 dimension, that issues. A extra aggressive and clear marketplace for PBM providers will assist preserve that contest honest and clear – to the profit of consumers 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, wise regulation and vocal customers would possibly repair.
