CMS Freezes Elevance MA Enrollment Over Risk-Adjustment Data Disputes—Raising the Stakes on Compliance Infrastructure
CMS has suspended new enrollment in Elevance Health’s Medicare Advantage plans, citing the insurer’s failure to submit risk-adjustment data corrections through required federal electronic systems. The dispute centers on Elevance’s use of encrypted USB drives—rather than designated digital channels—to report potential overpayments between 2018 and 2025, despite repeated CMS directives to change course. The freeze takes effect at month’s end and will block enrollment for individuals aging into Medicare, those with qualifying life events, and certain special needs plan applicants.
For industry partners, this signals how seriously CMS is willing to enforce data-submission protocols—a warning worth heeding as health systems face their own expanding reporting obligations, from 340B transparency requirements to mandatory payment model participation. Health systems and their partners should assume increasingly lower tolerance for noncompliance in their own reporting workflows.
Additionally, the freeze adds to a broader pattern of Medicare Advantage retrenchment that is gradually narrowing patient access to MA plans. That shift matters: as MA coverage becomes less available or less stable in certain markets, health systems and their partners will need to rethink payer mix assumptions, patient access strategies, and the infrastructure supporting both.
