The Health and Human Services (HHS) Office of Inspector General (OIG) on September 16, 2025 added to its workplan “Medicare Advantage Enrollment Manipulation Schemes,”  a new item.

To address schemes of improper influencing Medicare Advantage (MA) enrollment, the OIG will conduct a large-scale analysis of enrollment and disenrollment data to identify aberrant patterns that may signal improper Medicare Advantage organization (MA)) actions to influence enrollment.

Examples highlighted in the announcement include enrolling beneficiaries into MA plans without their consent, structuring incentive payments to agents to minimize enrollment of people with disabilities, and paying kickbacks to providers in exchange for enrollments.

OIG acknowledges to date, enrollment manipulation schemes have been identified primarily through whistleblowers, with minimal visibility into schemes that go unreported.
