Federal Enforcement Actions Against Medicare Advantage Plans

Listen to this summary

The authors aimed to examine the enforcement actions taken by the Centers for Medicare & Medicaid Services (CMS) against Medicare Advantage (MA) contracts from 2010 to 2023, focusing on the characteristics of the contracts and beneficiaries involved. They found that enforcement actions were variable over the years, predominantly consisting of monetary penalties, and raised concerns about their effectiveness in ensuring compliance with federal standards. The study suggests a need for further evaluation of oversight mechanisms to better protect beneficiaries and uphold program integrity.
