9*13*2018 - PBMs Are Hogging Our Drug Discounts

The Trump administration has aimed a dagger at the heart of high pharmacy bills: the go-betweens in the supply chain that have been gouging insurers, drugmakers, and consumers.

Through its blueprint to reduce drug spending—called American Patients First—the administration invited public comment on the role of pharmacy benefit managers. These are the mega-corporations that health insurers hire to administer their drug benefits.

Officials surely got an earful. In their role as go-betweens, PBMs negotiate big discounts from drugmakers. But rather than passing those savings on to insurers and consumers, they have found ways to pocket many of the proceeds for themselves.

The sums involved are huge. If just one-third of the total discounts PBMs negotiate for Medicare’s drug benefit were passed on to patients at the pharmacy counter, seniors would have nearly $20 billion more in their pockets over the next decade. The top three PBMs—Express Scripts, CVS Caremark, and OptumRx, who together control 75% of the market—collected more than $10 billion in profits in 2015.

A recently leaked contract reveals the tactics PBMs use to secure savings for themselves.

First, PBMs tend to hog rebates. Drug manufacturers offer PBMs a percentage discount or negotiated “rebate” off a drug’s list price. In exchange, the PBM agrees to cover the drug under its affiliated insurance plans, thus making it available to more consumers.

The majority of rebate dollars should, in theory, flow back to health plans. Then the plans can pass those savings to patients in the form of lower premiums or out-of-pocket expenses.

But the leaked contract with Express Scripts, the nation’s largest PBM, gets crafty with its definition of “rebate.” The contract carves out so many exceptions to the “rebate” that the PBM itself ends up retaining most of the negotiated discounts for itself.

For instance, PBMs receive extra “inflation payments” from drug manufacturers to cover annual increases in a drug’s list price. But these payments are not classified as rebates. Similarly, PBMs charge drug companies “administrative fees,” “service fees,” and more for their services. But these fees also aren’t considered rebates. So PBMs don’t pass them along to health plans.

Second, the document reveals that Express Scripts uses cryptic algorithms to reclassify generic drugs as brand name drugs. Drugmakers usually offer higher discounts for generics than they do for brand drugs. If a PBM gets a big discount on a generic drug, and then reclassifies it as a brand drug, it avoids passing along the full discount to the health plan it’s representing. The PBM essentially buys the drug low, sells it high, and pockets the excess.

PBMs are knowingly profiting off the backs of American patients, pharmacists, and innovators. It’s time for them to change their shady practices—and pass on discounts to patients. The sunlight the Trump administration is calling for will be a great disinfectant.
