As Medicare Advantage continues to grow, a gradual but significant reshaping of the Medicare program is taking place.
A new KFF analysis finds that nearly half of eligible Medicare beneficiaries – 28.4 million out of 58.6 million Medicare beneficiaries overall – are now enrolled in Medicare Advantage plans. That represents a more than doubling of the share of the eligible Medicare population enrolled in such plans from 2007 to 2022 (19% to 48%). Enrollment is projected to cross the 50 percent threshold as soon as next year, making Medicare Advantage the predominant way that Medicare beneficiaries with Parts A and B get their coverage and care.
