There is a tendency to overlook the multiple factors that contributed to the problem of prescription opioid misuse, abuse, overuse and diversion that began in the 1990s. Typically, the media has focused on drug manufacturers and doctors running pill mills as the chief villains. It’s important, however, to shed light on other stakeholders which possibly drove the opioid crisis, including payers and pharmacy benefit managers.

The prescription drug supply chain for opioids is extraordinarily complex and highly regulated. The key stakeholders include pharmaceutical manufacturers, federal and state regulators, wholesaler distributors, pharmacies, payers, PBMs, physicians and patients. Except for the patient, every stakeholder in the prescription opioid supply chain is licensed, and supply is regulated by the federal and state governments.

A recent Barron’s exposé details the role of PBMs in possibly fueling the opioid crisis. PBMs are important intermediaries in the prescription drug ecosystem, wielding power over which medications patients have access to and how much they cost. What the Barron’s article doesn’t emphasize is that PBMs serve at the behest of payers, which include employers, health plans and government agencies. On behalf of payers, PBMs negotiate net prices for drugs in conjunction with determining their positioning on formularies, or lists of covered medicines.

The Barron’s report reveals that the largest PBMs—CVS Caremark, Optum Rx and Express Scripts—played a part in establishing the net prices and formulary placement of OxyContin, a Food and Drug Administration-licensed opioid that has been at the center of what is often called the opioid epidemic. In a period that lasted 12 months between late 2016 and late 2017—quite far along into the prescription opioid crisis that commenced at least 15 years earlier—these companies were paid more than $400 million in fees and rebates from Purdue Pharma, OxyContin’s manufacturer. PBMs assert they pass the majority of rebates back to their payer clients, who are employers, health plans and government agencies. The figures cited are as high as 99%.

Nonetheless, according to Barron’s, PBM rebates were linked to dosage and the number of pills prescribed. The higher the dosage, the larger the rebate. As such, PBMs facilitated overutilization of the pain medication.

In collaboration with PBMs, the public insurance payers Medicare and Medicaid have played a key role facilitating access to prescription opioids. The epidemic has disproportionately affected Medicaid beneficiaries, who have been prescribed pain relievers at higher rates than those with other sources of insurance.

In addition, states are responsible for regulating their respective health insurance industries. This includes oversight with respect to formulary standards operated by Medicaid state agencies, managed care plans and PBMs; in the case of prescription opioids this relates to the status of such products and non-opioid treatment alternatives on formularies.

Medicaid is constrained in its ability to remove prescription opioids from formularies designed by state agencies or managed care plans in cooperation with PBMs, as the program is subject to federally mandated rebate agreements with pharmaceutical manufacturers that require virtually all FDA-approved products to be covered by Medicaid. Nevertheless, Medicaid invariably has a great deal of latitude regarding use of formulary management tools, such as prior authorization, quantity limits and step therapy (requiring that patients fail first on a preferred medication before stepping up to a non-preferred treatment).

Yet, while a prescription opioid crisis was unfolding and in many cases known to state authorities, state payers working with PBMs provided unfettered access to many prescription opioids, which may have fueled the existence of pill mills. Until recently, many states had relatively lax policies in place for coverage of certain immediate release prescription opioids. Additionally, the majority o
