19 health systems dropping Medicare Advantage plans

 Hospitals and health systems continue to sever ties with certain Medicare Advantage plans in 2026, citing persistent frustrations with prior authorization denials and slow reimbursement from insurers.

MA now covers more than half of the nation’s older adults, making these contract terminations increasingly consequential for patient access. Becker’s has tracked these decisions since 2023; our 2025 coverage is here.
