The PBM Transparency Reckoning: Fiduciary Duty in the Crosshairs

On January 30, 2026, the DOL issued a proposed rule that would mandate unprecedented transparency into PBM compensation for self-insured employer plans. Under the proposal, PBMs would be required to disclose direct and—crucially—indirect compensation, including rebates, spread pricing, and administrative fees.

For brokers, this isn't just a "news item." It is a fundamental shift in how you must justify your value and manage your liability.

The End of "Set It and Forget It"

Historically, many plan fiduciaries (your clients) treated PBM arrangements as too technical to scrutinize. The DOL is ending that era. The proposed rule fulfills the 2025 Executive Order 14273, making it clear that fiduciaries are expected to not only obtain PBM data but to evaluate it.

If the rule is finalized, brokers will be expected to help clients navigate:

1. Rebate Pass-Throughs: Identifying exactly how much of a manufacturer’s rebate is staying with the PBM versus going back to the plan.
2. Spread Pricing Disclosures: Seeing the difference between what the plan is charged and what the pharmacy is paid on a per-drug basis.
3. Broker/Consultant Compensation: The rule requires disclosure of indirect compensation from PBMs to consultants. If you are receiving overrides or "marketing fees," they will now be line items in a client's report.

Why This Matters for 2026 Strategy

In a market where medical costs are projected to rise 9% and prescription drugs 12%, PBM reform is the most potent cost-containment lever available.

Brokers who proactively bring this to clients—rather than waiting for the DOL to mandate it—are positioning themselves as true fiduciaries. Use this window to recommend "PBM Audits" and "Transparent/Pass-Through" PBM models. The market is shifting toward flat-fee PBM arrangements where the incentive is to lower the client's cost, not maximize the spread.

The Compliance Checklist

• March 31, 2026: Deadline for public comments on the DOL rule.
• July 1, 2026: Earliest expected effective date for new plan years.

Action Step: Review all service agreements. Ensure your PBM vendors can provide "Formulary-level" data. If they can't, it’s time to shop the market.
