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 Williamson 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 Williamson County specifically.
  • Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Williamson 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.
