This week, I’m rerunning some popular posts before the holidays. Click here to see the original post and comments from August 2018.
This rerun explains how and why PBMs are shifting responsibility and blame toward third-party payers. In 2019, we'll hear much more about how payers' use of rebates affect patients' out-of-pocket costs and distort the drug channel. Addressing the problems will require a major rethink of commercial and Medicare Part D pharmacy benefit designs. For my related $0.02 on the politics of "drug prices," see also Drug Prices After the Midterms: Five Crucial Implications of Pharmacy Benefit Design.
P.S. Drug Channels was sad to hear about the passing of Stephen Hillenburg, creator of SpongeBob Squarepants.
Last week, the two largest pharmacy benefit managers (PBMs)—CVS Health and Express Scripts—both stated that rebates now account for a small part of their profits. The companies therefore strongly implied that they could survive in a world in which PBMs did not participate in the flow of funds from a brand-name manufacturer to a plan sponsor. Below, I unpack the new disclosures, which move us materially closer to a new model.
Hmm. The two biggest PBMs and at least one major manufacturer (Pfizer) have now implied a willingness to change. So what’s to stop massive drug channel disruption?
CVS Health perhaps inadvertently identified the real barrier to a system without rebates: employers and health plans. As you will see below, CVS Health disclosed for the first time the massive gross-to-net bubble within its commercial book of business. The new information confirms that plan sponsors are hoarding rebates rather than sharing the savings with the employees whose prescriptions generated the rebate funds.
If we really do migrate to a system without rebates, PBMs’ reportedly minimal profits from rebates mean they could escape drug channel disruption unscathed. The focus will now turn to the plan sponsors that are absorbing rebate dollars. Whether plan sponsors realize it or not, they are the next target.
