A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).

Why your county matters for coverage
In Wisconsin, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Jefferson County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Wisconsin Medigap Helpline gives free, unbiased counseling at 800-242-1060. Ask which plans serve Jefferson County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Jefferson County ZIP code to see what is offered.
- Medicaid: apply through BadgerCare Plus (Wisconsin Department of Health Services).
Wisconsin note: Wisconsin's Medicare counseling program goes by a distinct name, the Medigap Helpline, rather than a more generic SHIP label, and it's specifically run by the Board on Aging and Long-Term Care rather than the Department of Health Services that runs BadgerCare Plus.
