Using Data-Driven Coverage Assessments to Unlock Medicare Part D Formulary Intelligence
Why Formulary Coverage Assessments Matter
Formulary coverage assessments are a critical component of successful market access strategies. As payer policies grow more complex and cost-containment tactics become more aggressive, pharmaceutical manufacturers must stay ahead of how coverage decisions impact product access, prescriber behavior, and ultimately, patient outcomes.

In 2025, plans increasingly adopted utilization management (UM) tools such as prior authorization and step therapy, raised cost-sharing requirements, and adjusted tier placement. Manufacturers should carry these lessons forward into 2026 planning. These changes can vary widely across payers and geographic regions, making it more difficult to maintain a clear understanding of where a product stands or where it’s being left behind.

To transform these insights into actionable strategies, it’s important to consider the specific business questions a coverage assessment can help answer.
