The 340B Rebate Model Pilot marks a significant evolution in how covered entities manage drug purchasing and compliance. Beginning January 1, 2026, nine high-impact medications will transition to a rebate-based model, with Entresto joining in April. This shift moves organizations away from upfront discounts toward a post-purchase rebate process, introducing new challenges in cash flow, operational workflows, and compliance oversight. While the start date is critical, success depends on building sustainable strategies that extend well beyond the initial implementation phase.

Understanding the Landscape

The pilot applies to ten drugs selected under the Inflation Reduction Act’s Maximum Fair Price program, including Eliquis, Enbrel, Farxiga, Imbruvica, Januvia, Jardiance, Novolog/FiAsp family, Stelara, Xarelto, and Entresto. Covered entities will purchase these medications at Wholesale Acquisition Cost (WAC) and later submit claims through Beacon Channel Management to receive rebates. These rebates will equal the greater of WAC minus the 340B ceiling price or WAC minus the MFP. This dual-pricing complexity requires robust data governance and precise eligibility logic to avoid compliance pitfalls.

Strategic Decisions Beyond January 1

While preparing for go-live is essential, leaders must think beyond the first submission cycle. How will your organization manage cash flow over the next six months as rebate timelines stabilize? Will you centralize WAC purchasing or allow distributed control? These decisions impact working capital and inventory management. Additionally, consider how to integrate Beacon workflows into long-term operational plans, ensuring that data mapping, submission monitoring, and reconciliation processes become routine rather than reactive.

Key Questions for Sustainable Success

To build resilience, leaders should ask: What mechanisms will guarantee accurate rebate tracking and timely escalation when discrepancies arise? How will we validate that rebate amounts align with eligibility rules? What is our documented process for resolving exceptions, such as claim reversals or manufacturer repayments? And importantly, how will we maintain audit readiness as the program matures and regulatory scrutiny intensifies?

Building Reliable Processes and Technology Integration

Success in the rebate model depends on creating a seamless data pipeline—from dispensing records to Beacon-ready submission files. Organizations should implement dual-approval workflows for submissions, timestamped logs, and reconciliation dashboards to monitor rebate receipts. Technology platforms like Bluesight’s 340BCheck and CostCheck can automate invoice-level tracking and audit reporting, reducing manual errors and improving compliance confidence.

Looking Ahead: Compliance and Continuous Improvement

Beyond initial implementation, ongoing compliance will require quarterly training, internal audits, and proactive monitoring of policy changes. Legal challenges and advocacy efforts could reshape timelines or requirements, so maintaining flexibility is key. By embedding these workflows into organizational culture, covered entities can transform the rebate model from a regulatory burden into a strategic advantage.
