Trends in C-SNP Enrollment and Offerings, 2018-2025
ATI Advisory analyzed 2018–2025 Medicare Advantage (MA) enrollment data to examine growth and trends in Chronic Condition Special Needs Plans (C-SNPs). Enrollment in C-SNPs increased by 67% year over year, with the vast majority of beneficiaries concentrated in plans targeting cardiovascular conditions and diabetes. Most new enrollment came from Medicare Fee-for-Service or non-SNP MA products, signaling continued movement into condition-specific plan options.
Dual eligibles remain an important segment of C-SNP enrollment, though their overall share declined compared to prior years. In January 2025, one in five C-SNP enrollees was dually eligible, with notable variation across states. Through targeted care models and benefit design, C-SNPs present a critical opportunity for organizations to better support Medicare beneficiaries with complex chronic care needs.
