Medicare Advantage (MA) encounter data is no longer just a reporting requirement for health plans. As more than half of all Medicare beneficiaries are enrolled in MA, CMS is increasingly relying on encounter data to inform quality measurement, program oversight, and broader Medicare policy decisions. Recent actions by the agency signal growing confidence in the data and suggest encounter data could play a much larger role in shaping both MA and traditional Medicare in the years ahead.
From hospital quality programs and readmissions measures to potential future changes in risk adjustment and MA payment benchmarks, encounter data could become a foundational input for Medicare policymaking. In this +Insight, we examine how CMS is using encounter data today, where policymakers may take it next, and what providers, health plans, life sciences companies, and other healthcare stakeholders should be watching as this increasingly important dataset continues to evolve.
