Diabetes medication adherence is a quality and performance metric within the STAR rating system that evaluates the extent to which Medicare Part D and Medicare Advantage beneficiaries fill their prescriptions for oral diabetes medications often enough to cover 80% or more of the days they are supposed to be taking the medication. Importantly, this measure is triple weighted in the STAR Rating system, so even small improvements in adherence can materially influence a plan’s overall rating, making mastery of this metric essential.

AAVBC’s Quick Reference Guide distills regulatory expectations, scoring methodology, measure weighting, workflow optimizations, best practices, and performance benchmarks for proper diabetes medication adherence. These guides provide organizations with a clear understanding of diabetes medication adherence so that they can effectively implement it into their clinical practice; in doing so, they can maximize their financial incentives, market competitiveness, and regulatory compliance in the ever-evolving Medicare Advantage landscape.

AAVBC’s Deep-Dive series offers a comprehensive, structured analysis of diabetes medication adherence — moving far beyond quick-reference essentials. These guides provide an integrated review of measurement importance and impact, clinical integrations, technical details, challenges and barriers, strategies for team coordination and quality improvement as well as regulatory and financial considerations. The Deep-Dives combine evidence-informed clinical guidance with practical operational tools to support a deeper understanding of diabetes medication adherence and provide care teams with strategies to thrive within a value-based model.
