Medicare (United States)
Regional preferred provider organizations (PPOs) were established to provide rural beneficiaries greater access to Medicare Advantage plans and cover entire statewide or multi-state regions. Regional PPOs accounted for 5% of all Medicare Advantage enrollees in 2020. About 24 million people, or 36% of those receiving Medicare benefits, were enrolled in a Medicare Advantage plan in 2020. That number is expected to climb to more than 26 million in 2021.
