Transparent-Pricing PBM

A transparent-pricing PBM is a pharmacy benefit manager that charges a defined per-script or per-member administrative fee and passes through the actual acquisition cost of drugs, plus 100 percent of manufacturer rebates, to the plan sponsor. It's the opposite of the traditional spread-pricing PBM model, where the PBM charges the plan more than it pays the pharmacy and keeps the difference as revenue.

The transparent PBM model has been growing quickly. Vendors like Navitus, Rightway, SmithRx, Capital Rx, and MedImpact operate on defined-fee, full-pass-through contracts and typically produce 10 to 20 percent lower net drug spend for plan sponsors compared to legacy PBM contracts, even before accounting for improved formulary flexibility. The trade-offs are real: transparent PBMs often have narrower retail networks (though this is improving quickly), less-integrated tools, and administrative fees that are visible on the invoice (which can look higher even though total spend is lower). The transparency also creates its own scrutiny — employers see every drug's cost, which sometimes prompts uncomfortable conversations about specialty drug spending they hadn't previously understood. On the compliance side, transparent PBM contracts are much cleaner for CAA gag-clause attestations because there are no hidden pricing arrangements to disclose. Consultants and plan advisors increasingly recommend a transparent-pricing PBM as the default choice for new self-funded plan setups.

The takeaway: if you're evaluating PBMs for a self-funded plan, request bids from at least one transparent-pricing PBM alongside the incumbent. The pricing model differences alone frequently reveal 15 to 25 percent in previously-hidden spread the incumbent was keeping.
