What you can do

Where this comes from, and its limits

This page was built from public CMS files: CMS CY2026 Landscape (Sept 2025 release), CMS CY2027 Landscape (Sept 2026 release), and CMS Monthly Enrollment by Contract/Plan/State/County, Sept 2026. A plan is listed when CMS's 2026 Landscape lists a plan in a county and CMS's 2027 Landscape does not list any segment of that plan there. Member counts are the people CMS reports enrolled in the plan in those counties in September 2026. CMS hides enrollment counts of 10 or fewer, so "at least" means the real number can be higher.

This is what CMS's files show. It is not a notice about any one person's coverage, and CMS can correct or update its files after we built this page. Your plan's written notice is what tells you what is happening to your coverage, so check it and confirm with the plan.

Common questions

If a plan is on this list, will it not be there next year?

Not necessarily, and this page cannot tell you that about your plan. It shows only that CMS's 2027 plan list does not show a Aetna plan in a South Dakota county where CMS's 2026 plan list showed it. Plans are sometimes renumbered or replaced, and a company often moves members to another of its plans. The written notice from your plan is what tells you what is happening to your coverage, so check it and confirm with the plan.

When can I choose a different plan?

The Annual Enrollment Period generally runs October 15 to December 7, with new coverage starting January 1. People whose plan is not renewing generally get a Special Enrollment Period that runs from December 8 through the end of February. Check your own dates with your plan or with us.

Who can help me compare my options?

Talk with us: leave your number below or call 855-367-1095. We do not offer every plan, so we will say plainly what we can and cannot help with.

Where do these numbers come from?

CMS CY2026 Landscape (Sept 2025 release), CMS CY2027 Landscape (Sept 2026 release), and CMS Monthly Enrollment by Contract/Plan/State/County, Sept 2026. CMS hides enrollment counts of 10 or fewer, so "at least" means the real number can be higher.

Is Aetna leaving South Dakota?

CMS's 2027 files show no plan from some of these companies in some South Dakota counties, and other plans continuing elsewhere. Check your county and your plan's notice.
