New demands on PBMs
PBMs have long operated successfully within a complex ecosystem involving manufacturers, pharmacies, employers and patients. Traditional models that tied rebates, revenue and prescription volume to drug prices created a perceived conflict: Higher system costs could translate into higher PBM revenue.
But employers increasingly want greater visibility and more clarity. And Optum Rx has been listening.
We have been expanding transparency for years by making financial flows independently auditable and providing greater visibility into rebate economics and formulary decisions through our Pharmacy & Therapeutics Committee.
We have also:
- Committed to passing through 100% of manufacturer rebates by January 1, 2028
- Transitioned all community and independent pharmacies to cost-based reimbursement models
- Increased reimbursement rates for more than 2,300 unaffiliated pharmacies
In parallel, we’ve reduced administrative burden by eliminating 33% of reauthorizations since 2025.
