Medicare Part D insurers who demand rebates from drug makers steer patients away from cheaper generics—meaning patients and taxpayers lose while insurer pharmacy benefit managers (PBMs) gain, finds an investigation by the Office of the Inspector General (OIG) of Health and Human Services.
The context: PBMs, many of which are owned by insurers, demand rebates from drug manufacturers in exchange for including their products in the formulary of covered drugs. But new drug pricing legislation ignores PBMs, the real driver of high drug costs.
What OIG found: After PBMs take their rebates, Epclusa, a brand-name hepatitis C drug with a $65,000 per-patient price tag, costs private Medicaid Part D insurers about $30,000 per patient, according to the OIG investigation.
But: Patients are charged based on the full price of $65,000—meaning they exceed their annual drug copay and receive “catastrophic coverage” from Medicare (and ultimately taxpayers), which picks up 80% of the cost.
So, because patients are charged the full price and Medicare covers much of the cost, private insurers are incentivized to forgo cheaper generics. In this case, the generic hepatitis C drug costs only $21,000 after rebates. This happened in 70% of cases for this drug, per OIG.
Insurers’ gain is beneficiaries’ loss: “The large rebates offered by manufacturers for higher-cost hepatitis C drugs benefit plan sponsors but provide little relief to beneficiaries who received the drugs or the Medicare program,” the report finds.
Dan’s Deep Dive: “Three insurance company PBMs control 80% of patients’ medicines and use their market power to get tens of billions of dollars in discounts on medicine, but don’t share the savings with the patients,” says Dan Durham, BIO Senior Health Policy Advisor.
