Counties = distinct state and county pairs where the insurer's CMS parent organization offers any Medicare Advantage plan (category MA or SNP, H and R contracts) in the CMS plan year 2026 and 2027 files; percent = change / 2026 counties. New Devoted counties losing another insurer = Devoted counties in 2027 not in 2026 where at least one other parent organization offering a plan there in 2026 offers none in 2027. Members = September 2025 and 2026 CMS enrollment in individual plans matched to the plan files (H/R contracts, plans 001-799); plan ends = members whose plan is not continued in their county and is not moved by the CMS 2027 plan crosswalk. Zero premium = share of plan and county rows, non-special-needs Medicare Advantage plans with drug coverage, 2027, in counties where Devoted sells, with a $0 monthly premium. · CMS Medicare Advantage plan files (Landscape) CY2026 and CY2027 (medicare_silver.fact_ma_landscape, queries 110c9f17, ee516fc2, aa29efc1); CMS Monthly Enrollment September 2025 and 2026 and CMS Plan Crosswalk 2027 via get_landscape_exits (queries 86a2c8d3, e775b85e, fe039b7d); CMS Monthly Enrollment by Contract September 2026 (42 Devoted contracts sum to 532,676, matching get_stars_rollup); CMS 2026 and 2027 Star Ratings Summary (H7993: 5 to 4.5, not restated). · 5 rows
The posted figure
Read with
- Counts counties where an insurer offers any plan; it says nothing about how many members it will win there.
- Insurers are CMS parent organizations as reported in each year's file; Aetna is CVS Health's parent organization line.
- Individual plans only for member figures; employer group plans (plan IDs 800 and up) are not in the CMS plan files. September 2026 members are 520,784 on the matched base and 532,676 across all 42 Devoted contracts.
- New counties losing another insurer measures overlap in place, not that members move from the leaving insurer to Devoted; the post does not claim they do.
- Zero premium compares plan options, not members; it covers non-special-needs plans with drug coverage only. Devoted's in-network out-of-pocket maximum is about the same as the other insurers in its counties (median about $7,150 against $7,100), so the post makes no out-of-pocket claim.
- Star Ratings: H7993 (Texas, 55,001 members) is Devoted's largest contract; its Overall went from 5 (2026) to 4.5 (2027), which still earns the quality bonus. Across all Devoted contracts, 78.6% of rated members are in 4+ star contracts for 2027 against 70.7% for Medicare Advantage.
- Suppressed enrollment cells (under 11 members) count as 0.
