On January 30, 2026, the Department of Labor issued a proposed rule requiring pharmacy benefit managers (PBMs) to disclose compensation to self-insured plan fiduciaries. This move follows broader regulatory efforts to increase transparency in drug benefit management.
Why it matters
The proposal aims to curb opaque pricing structures in the prescription market, where PBMs negotiate rebates from manufacturers and route claims through their own integrated pharmacy networks. These disclosure requirements seek to clarify costs for employers managing their own health plans.
There are 66 PBMs operating in the United States, with the three largest firms accounting for 79 percent of all prescription claims in 2022. The new regulatory environment shifts focus toward transparency for plans impacted by the Consolidated Appropriations Act 2026.
The players
Department of Labor
The federal agency responsible for overseeing employee benefit plans and enforcing fiduciary standards for health and retirement funds.
The details
PBMs frequently negotiate rebates from drug manufacturers, sometimes retaining portions of these savings rather than passing them fully to health plans. The proposed rule mandates that PBMs report compensation details to self-insured plan fiduciaries to allow for clearer oversight. Combined with the Consolidated Appropriations Act 2026, these regulations force a more granular accounting of how integrated pharmacy networks impact plan costs.
Timeline
2022 saw three major PBMs process 79 percent of all US prescription claims.
The Department of Labor issued the proposed rule on January 30, 2026.
The Consolidated Appropriations Act 2026 was signed into law in February 2026.
Reporting requirements under the new act take effect on January 1, 2029.
Market Landscape
This proposal extends the transparency mandates established by the Consolidated Appropriations Act 2026 to include detailed PBM compensation reporting. It follows a multi-year trend of federal intervention into the vertically integrated relationships between major insurance conglomerates and PBMs.
Operators managing self-insured plans should review current PBM contracts to ensure they can accommodate upcoming disclosure requirements. Prepare to audit administrative fee structures ahead of the January 1, 2029, enforcement date for associated reporting mandates.
The takeaway
Transparency requirements for health plans are tightening, shifting the burden onto plan fiduciaries to audit PBM compensation. Review your upcoming plan renewals to ensure your benefits team is tracking rebate pass-through metrics in anticipation of the 2029 reporting deadline.
