Three of the biggest insurers sell in fewer counties for 2027. Devoted Health adds 342.

For 2027, Centene, Aetna and Humana sell Medicare Advantage in fewer counties. Devoted Health adds 342 counties and drops none.

Devoted goes from 999 counties in 29 states to 1,341 in 34. Centene cuts 161 counties, Aetna 67, Humana 57. UnitedHealth is flat.

If your plan is leaving your county, Devoted may be one of the insurers moving in. 59% of its new counties are losing at least one other insurer for 2027, against 47% of all counties.

It is keeping the people it already has. Only 1.7% of Devoted's members are in a plan that ends next year. Across Medicare Advantage it is 10.6%, about 3.15 million people.

It also more than doubled in a year, from about 204,000 members to about 521,000. In the counties where it sells, 97.7% of its plans with drug coverage charge no monthly premium. For the other insurers there it is 59.2%.

The number to watch is Star Ratings. Its biggest plan contract, in Texas, went from 5 stars to 4.5 for 2027. That still earns the quality bonus.

This year three of the biggest insurers decided where to leave. Devoted decided where to go.

Measure
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.
