PBMs Are Starting Group Purchasing Organizations Leading to a Question of Why

The Big Three all set up group purchasing organizations recently, but some industry observers question the timing of the move and who will benefit.

In 2019, Express Scripts PBM (pharmacy benefit manager) formed Ascent Health Services GPO (group purchasing organization), based in Switzerland. In 2020, CVS Caremark formed Zinc GPO. And in 2021, OptumRx formed Emisar Pharma Services, based in Ireland. With pharmacy benefits for approximately 75% of U.S.-covered lives under their control, why would these PBMs need GPOs — to capitalize on their scale to get better drug prices?

“In each case, there’s what the PBM said, and then you have to do your best to fill in the blanks of what could possibly be going on,” says Howard Deutsch, principal at ZS Associates, a global professional services firm with offices in Boston. “They haven’t said a heck of a lot. They’ll say things about serving customer needs, but nowhere will you find some particular customer need that is better being served by the existence of this new entity.”

With the Big Three PBMs already covering a majority of prescription claims, “the idea that they needed to create some sort of new entities so they can have some bargaining power is kind of ludicrous,” Deutsch says. “They already had plenty of bargaining power and were using that quite effectively. It’s unclear from what they’ve publicly said what the value proposition is to the rest of the healthcare system. The value proposition to the PBM is somewhat clear.”

Pricing is one reason Ken Paulus, president and CEO of Prime Therapeutics, gave in an interview last year with Managed Healthcare Executive®. Prime entered into an agreement with Express Scripts three years ago whereby Express Scripts handles some of the negotiations with pharmaceutical manufacturers. As a minority owner of Ascent GPO, Prime has direct access to all the GPO contracts and received savings it would not have gotten otherwise, Paulus said in the interview. Prime still processes its own claims and performs utilization management, Paulus said, but the GPO was “a fairly elegant solution for us to save significant dollars for clients and members and employers, but do so without giving up our strategic optionality, which is continuing to run our own business.”

Alan Lotvin, president of CVS Caremark, CVS Health’s PBM, said in a recent interview with Managed Healthcare Executive® that the GPO was a way for CVS Caremark to “separate out all the different lines of business onto separate contracts” and gain some bargaining power.
