No offense, but the article got PBMs entirely wrong.<p>Any savings from rebates is typically passed back to the one paying.  In fact, it would be odd if an insurance company <i>didn&#x27;t</i> have that in their contract.<p>I&#x27;d say PBMs have done a ton on keeping drug costs down.  Hell, look at HCV!  Express Scripts cut a deal with Abbvie on their new HCV drug and <i>excluded</i> Solvadi and Harvoni from their formulary.<p>What happened?  Gilead came out and offered a 20-30% discount on their drug to pretty much every other PBM and insurance company.
