Why your county matters for coverage
In Idaho, 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 Washington County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Idaho SHIBA (Senior Health Insurance Benefits Advisors) gives free, unbiased counseling at 1-800-247-4422. Ask which plans serve Washington County specifically.
- Marketplace plans: shop through Your Health Idaho; enter your Washington County ZIP code to see what is offered.
- Medicaid: apply through Idaho Department of Health and Welfare.
Idaho note: Idaho also runs a state reinsurance program that helped bring individual-market premiums down roughly 18% for 2026 -- a state-level lever most federal-exchange states don't have, on top of running Your Health Idaho itself.
