EP365: The Real Deal With PBM Contracts and Drug Rebates, With Scott Haas
April 28, 2022

One of my mentors often said price is irrelevant. He said he would sell anything for any price as long as he could define the terms of the deal. During this conversation today with Scott Haas about PBMs, that quote was playing in my head like an earworm.

I’m henceforth gonna struggle with the term rebate to define dollars that the PBM gets back from Pharma, because, according to my guest in this healthcare podcast Scott Haas, it turns out “rebates” comprise only about 40% of those back-end dollars that some PBMs manage to score from pharma manufacturers. I don’t have any insight really into this, but Scott Haas certainly does—and this is the average that he has seen in his work and that we’re going to dig into today. But in sum … wow! Let me just repeat that a mere 40 cents on the dollar of the gross amount that PBMs take in “rebates” from Pharma these days winds up going back to plan sponsors, even plan sponsors who are getting “100% of the rebates.”

If you didn’t understand what I just said, no worries. I’m gonna explain it right now. If you did and you know the why behind all of this also, you could probably skip ahead about five minutes.

Here’s the backstory on this whole rebate fandango. Let’s start with part one of what is a two-part transaction.

So, part one: the deal between pharma manufacturers and PBMs. In general, a pharma manufacturer signs a deal with a PBM to give back whatever percentage of their gross sales revenue to the PBM at the end of the year, say. It’s along the same lines as a cash-back coupon for the PBM.

Why would a pharma company be up for giving cash back like this? Well, to get on a PBM’s formulary, giving cash back is like the price of admission. PBMs have a lot of leverage, after all—at least the big ones. They control access to millions and millions of patient lives. So, if Pharma wants their drug to be accessible to those millions and millions of lives, they have to play the cash-back game, otherwise known as the rebate game. They have to agree to give back to the PBM a certain amount of cash on the back end.

So, PBM pays Pharma’s list price up front—that’s the gross amount paid, based on the list price of the drug—and then after all the cash back gets toted up at the end of the year, there’ll be a net price. List price or gross price minus the cash back equals net price. It’s this net price that’s the true kind of final price which the pharma company gets paid per script by said PBM at the end of the day.

These days, most everybody pretty much knows that PBMs are getting these so-called rebates—this cash back from pharma companies that I just explained. And it’s pretty common knowledge the so-called gross-to-net bubble (the gross-to-net dollar amount) is pretty huge, meaning the rebate or cash-back amount is pretty huge. And many have also noticed that the gross-to-net dollar amounts seem to be growing bigger and bigger every year. I mean, for one insulin manufacturer, consider this: Their list price, their gross price, is $350 per script. And their net price after cash back/rebates was $52 this past year. Wait … what? After all the cash back to the PBM, the insulin manufacturer got paid 86% less than their list price—$350 went down to $52 per prescription. The PBM vacuumed up 86% of the dough for every script written for this particular brand of insulin.  

OK … so, say Pharma gives $100 back to the PBM based on the terms of their deal. Call that part one of this example transaction.

Here’s part two: the deal between PBMs and health plans or self-insured employers. Health plans and self-insured employers are customers of the PBM. They hire PBMs to manage the pharmacy benefits for their members or employees.

So, because everybody knows this whole rebate thing is going on, as part of the contracts that the PBMs put in place with their customers (meaning the health plans or employers), the PBMs tell their customers that they’re going to give 100% of the rebates back to the plan/employer. So, you’d think that if the pharma manufacturer paid $100 to the PBM, that the customers of the PBM (the plan sponsors) would get the $100 back then, right? The PBM would pass on 100% of the savings, as it were, if they’re saying that they’re gonna give 100% of the rebates. I mean, if this is actually true, that $100 in and $100 out, then the PBM is potentially performing a useful service, right? They’re lowering drug costs for their customer, the plan sponsors for their members and employees.

Except … turns out, not so much. Because what is a rebate, really? A rebate can be anything the PBM defines as a rebate. And it turns out that, on average, as I said before, according to those in the know, something like $60 of that $100 is not a rebate. It’s an administration fee. Or a data fee. Or an education fee. A clinical program fee. Some other name that is not rebate.

As my guest Scott Haas says, the term rebate is meaningless because it can mean whatever the PBM wants it to mean. It’s like inconceivable from The Princess Bride. I do not think that word rebate means what you think it means.  

Now it is a tangled web we weave here, and for more on why I say that, listen to the episode with Chris Sloan (Encore! EP216) entitled “How Medicare Part D Plans Became Addicted to Drug Rebates.” There’s also a show with Pramod John (EP353) where we dig into, specifically, specialty drugs and rebating and so-called rebate walls.  

But net net, all of this probably myopic focus on rebates means that you have to keep an eagle eye out for so-called exclusions in contracts if you are a plan sponsor. So, what are exclusions?

This is that whole thing where some cheap generic is excluded from a PBM formulary while some expensive brand for the same condition is on formulary. Why would a cheap generic be excluded from a PBM formulary? Simple. Cheap generics don’t have rebates. PBMs lose a lot of money when some high-priced specialty drug, for example, goes generic. They might have made thousands of dollars per script on that high-priced brand by collecting its rebate. Think about that insulin example. The rebate is 86% of the cost of the drug. And everybody wonders why some cheap generic insulin or biosimilar or whatever isn’t on formulary. It is not a mystery when you’re dealing with for-profit enterprises built around a model of revenue maximization.

So, given all this, what’s my guest Scott Haas’s bottom-line advice in this whole thing? If you’re a health plan or employer and you’re trying to negotiate a PBM contract where your spend is predictable and your contracted price promises have any meaning whatsoever, Scott Haas’s advice is, you have to ensure that the contract defines the actual prices for the drugs in the contract. With absolute numbers. Not percentages off or weird formulas or the empty promise of getting an AWP or a WAC (which means average wholesale price or wholesale acquisition cost) or any of the other various acronyms for some drug pricing schema. All of these are basically shorthand for “this price could change at any moment.”

There’s a reason in-the-know people say AWP stands for “Ain’t what’s paid,” meaning ain’t what’s ultimately going to be paid by plan sponsors. What is necessary in PBM contracts is the final price—that number. Some digits with a dollar sign in front of them and a “per unit” after them. No acronyms and no percentage signs.

Whoever gets to define the terms ultimately controls the price. So, get the price up front.

As mentioned several times already, I am talking to Scott Haas, who is a senior VP over at USI Insurance Services. He’s speaking today from the perspective of a plan sponsor, meaning from the point of view of a health plan, including those health plans managed by and paid for by a self-insured employer and their employees.

For more information on PBMs and how drugs get adjudicated, listen to the show with AJ Loiacono (Encore! EP231), which was one of the most popular episodes over here at Relentless Health Value. Somebody on a LinkedIn post the other day commented on how much she appreciated AJ Loiacono’s frank assessment of things and how she would love to go to a meeting with more people similarly telling it like it is. That’s pretty much what we aim to do at every episode over here at Relentless Health Value, and AJ nails it on that objective for sure in this episode.  

One last thing, also on the show: Scott Haas brings up GPOs that the Big Three PBMs have been spinning up to aggregate and maximize all of those rebates that we just talked about. I discuss this exact topic at some length in another incredibly popular episode with Mike Schneider (Encore! EP288).
