In the United States, as in most other countries, it is illegal for pharmaceutical companies to bribe doctors or hospitals to prescribe their products. Those who get caught engaging in this sort of corruption can suffer severe penalties. For example, in 2020, the pharmaceutical giant Novartis agreed to pay the U.S. government almost $700 million to settle a case involving allegations that the company had violated the federal Anti-Kickback statute by offering “cash payments, recreational outings, lavish meals, and expensive alcohol” to doctors to induce them to prescribe Novartis drugs. Yet when pharmaceutical companies offer financial inducements worth billions of dollars to Pharmacy Benefit Managers (PBMs)—not the meager thousands spent on doctors—to promote use of their drugs, the conduct is entirely legal.

What, you may ask, are PBMs? Good question. Most laypeople outside the health care field are unfamiliar with PBMs, and may not even know they exist. But PBM’s play a crucial, if underappreciated and extremely complex role in determining prescription drug prices and insurance coverage decisions. Simplifying somewhat, PBMs’ primary function is to manage insurance companies’ prescription drug plans, a role that includes, among other things, negotiating with drug companies to determine which drugs insurance will cover, and which will be favored. Given that just three PBMs control over 80% of the prescription drug market, PBMs can have an enormous effect on pharmaceutical sales, as drugs that lack insurance coverage are significantly less attractive to consumers than those with coverage. Additionally, PBMs also reimburse pharmacies on behalf of insurance providers for the costs of filling beneficiaries’ prescriptions.

In short, PBMs, which stand in between many of the transactions in the pharmaceutical supply chain, play a major role determining the prices paid by insurers, pharmacies, and patients for prescription drugs. And although kickbacks to doctors, hospitals, insurance companies, and other actors in the system are strictly prohibited, drug companies can and do take advantage PBMs’ complex payment structures to discreetly offer financial inducements in order to gain PBMs’ favor during insurance coverage determinations. There are two main ways in which this de facto bribery occurs: Continue reading →
