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). Source: CMS Medicare Advantage and Part D landscape files for 2026 and 2027, and CMS enrollment data from September 2026.

Why your county matters for coverage
In Tennessee, 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 Gibson County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: TN SHIP (State Health Insurance Assistance Program) gives free, unbiased counseling at 1-877-801-0044. Ask which plans serve Gibson County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Gibson County ZIP code to see what is offered.
- Medicaid: apply through TennCare.
Tennessee note: Tennessee's children's health coverage program has its own distinct name, CoverKids, rather than being folded entirely into the TennCare brand -- worth knowing since a household can qualify for CoverKids even in situations where adult members don't qualify for TennCare.
