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 Illinois, 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 Greene County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Illinois Senior Health Insurance Program (SHIP) gives free, unbiased counseling at 800-252-8966. Ask which plans serve Greene County specifically.
- Marketplace plans: shop through Get Covered Illinois; enter your Greene County ZIP code to see what is offered.

Illinois note: Illinois is one of the most recent states to move off the federal Marketplace -- Get Covered Illinois only replaced HealthCare.gov as of the November 2025 open enrollment period, so older search results or bookmarks pointing to HealthCare.gov for Illinois are now out of date.
