Where should duals-focused sales teams and community partnerships deploy?
For plan year 2027, 192,040 dual-eligible people live in counties where no D-SNP is offered, and 3,390,214 live in counties with no HIDE or FIDE (integrated) D-SNP. California has the most duals without an integrated option (916,125). Dual-eligible and LIS beneficiaries do not have an open door every month. Their monthly special enrollment period is limited: it can be used to enroll in an integrated D-SNP (FIDE, HIDE or applicable integrated plan) or to leave Medicare Advantage for Original Medicare with a stand-alone Part D plan (42 CFR 423.38). Other changes wait for AEP or the MA Open Enrollment Period.
Rebuilt October 1, 2026 from June 2026 county dual counts and the CY2027 Landscape. The earlier ranking (“185K uncovered duals in Texas”, 2025 Q4) came from a curated extract and is archived in Methodology.
