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 Michigan, 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 Shiawassee County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: MMAP (Michigan Medicare/Medicaid Assistance Program) gives free, unbiased counseling at 800-803-7174. Ask which plans serve Shiawassee County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Shiawassee County ZIP code to see what is offered.
- Medicaid: apply through Michigan Department of Health and Human Services (MDHHS).
Michigan note: Michigan's Medicaid expansion program has its own distinct brand name, the Healthy Michigan Plan, rather than just being referred to as expanded Medicaid -- worth knowing since Michigan-specific materials and application flows generally use that name.
