Understanding SNPs

SNPs Help Over 6.4 Million People

As of December 2023, CMS SNP Comprehensive Report 6.4 million Medicare beneficiaries are enrolled in 1,335 plans. In regard to a SNP by SNP break down, 548,900 are enrolled in C-SNPs, 119,425 are enrolled in in I-SNPs and 5.7 million are enrolled in D-SNPs. Of the three types of D-SNPs, 499 Coordination-Only (CO D-SNPs) have 3 million enrollees, 66 FIDE D-SNPs have 420,847 enrollees, and 245 HIDE D-SNPs have 2.2 enrollees.

National SNP Growth and Distribution

The number of SNPs steadily has grown with significant jumps between 2019 and 2023.

Integration and D-SNPs

D-SNP distribution remains highly mixed by state with FIDE D-SNP concentration in six states, HIDE D-SNP in six states, and the remaining state with some form of integrated D-SNPs totaling 13 states. The remaining 25 states do not have D-SNP coordination efforts. See the map below for more detail. Source: MACPAC 2023

The Centers for Medicare and Medicaid Services (CMS) Financial Alignment Initiative (FAI) tested models to better integrate primary, acute, behavioral, and long-term services and supports.  FAI also provided participating states to share in savings.  Fifteen states were initially awarded demonstration contacts and implementation began in 2013.

The two models include (1) a prospective blended rate model for select health plans to provide both Medicare and Medicaid benefits to duals called the “capitated model”, and (2) a model that allows the state to take responsibility for coordinating the beneficiary’s care, called a “managed fee-for-service model (MFFS)”.
