21 Health Systems Exit Medicare Advantage Contracts in 2026

Becker’s Hospital Review is tracking 21 health systems that have terminated or are exiting Medicare Advantage contracts in 2026, citing persistent prior authorization denials and inadequate reimbursement from insurers. The trend has accelerated as MA now covers more than half of the nation’s Medicare-eligible population, making these exits increasingly consequential for patient access and health system revenues. Systems ranging from major academic medical centers to regional operators have cited administrative burden, payment delays, and unsustainable rate structures as primary drivers. The tracker continues to be updated as new decisions are announced, underscoring that the MA exit trend is ongoing — not a one-time correction.
