Medicare Advantage in 2025: Enrollment Update and Key Trends

kff-medicare-advantage-issue-brief on PayerIndex
Our Take: More than half of eligible Medicare beneficiaries are now enrolled in Medicare Advantage. Enrollment growth slowed to 4% in 2025, but SNP enrollment – especially C-SNPs – surged more than 70%. The shift toward higher-acuity special needs populations is reshaping who arrives at post-acute providers through MA.

The rapid growth in SNP enrollment, particularly among dually eligible and chronically ill beneficiaries, signals more complex, higher-acuity residents who will require stronger care coordination and reimbursement strategies tailored to each payer.


Medicare Advantage in 2025: Enrollment Update and Key Trends

More than half (54%) of eligible Medicare beneficiaries are enrolled in Medicare Advantage in 2025. While a growing share of Medicare beneficiaries are enrolled in a Medicare Advantage plan, the pace of the increase in enrollment slowed in 2025. In 2025, one in five (21%) Medicare Advantage enrollees is in a special needs plan (SNP), reflecting a steady increase in recent years. Almost half (48%) of the total increase in Medicare Advantage enrollment between 2024 and 2025 was among SNPs, up from 43% in the prior year.

Medicare Advantage enrollment grows, but not quite as fast, as concerns mount

Medicare Advantage enrollment grew by about 1.3 million beneficiaries, or 4%, over the last year, slowing the program’s explosive growth rate compared to prior years, according to a new analysis. KFF, the health policy research organization, reported Monday that more than half (54%) of eligible Medicare beneficiaries – 34.1 million out of about 62.8 million Medicare beneficiaries with both Medicare Parts A and B – are enrolled in MA for 2025.
