Figure 3. Enrollment in Dual-Eligible Special Needs Plans (D-SNPs) by Plan Type and Alignment Status in 2021 and 2022.

Includes Medicare beneficiaries with at least 1 month of full-benefit D-SNP enrollment in 2021 or 2022. Beneficiaries were assigned to the plan that they had for the most months during the study year. If 2 plans had the same number of months, beneficiaries were assigned to the last plan they had during the study year. The aligned D-SNPs were identified using the Applicable Integrated Plan indicator data published by the Centers for Medicare & Medicaid Services and linked by unique 5-digit contract and 3-digit D-SNP identifiers using the contract and plan benefit package numbers for Medicare Part C in the Master Beneficiary Summary File. For beneficiaries with a single combination contract number and plan benefit package number operating in 2 states with 2 separate D-SNP types (eg, 1 coordination-only D-SNP and 1 highly integrated D-SNP), the D-SNPs were treated as 2 separate plans.
