C-SNP plans had 430,000 members at the end of 2022. By October 2026 they had 1.86 million.

Medicare Advantage plans for people with chronic conditions had 430,000 members at the end of 2022. In October 2026 they had 1.86 million.

They are called C-SNPs. You can join one only if you have a qualifying condition, and 97% of their members are in plans for heart disease, heart failure or diabetes.

The video runs month by month from June 2008, county by county: C-SNP members for every 1,000 people eligible for Medicare.

Two insurers carry most of the growth since 2022. UnitedHealthcare added 641,000 C-SNP members and Humana 337,000, together 68% of the rise.

And 2027 adds more. Insurers will sell 754 C-SNP plans, up from 562, the most ever added in one year. Devoted Health alone goes from 122 plans to 255. In 1,483 counties there are more C-SNP plans on sale than in 2026, including 111 that get their first. 413 have fewer.

If you or a parent has diabetes or a heart condition, look at what is on sale in your county for 2027. Open enrollment ends December 7, though people with a qualifying condition can join a C-SNP at any time of year.
