Why your county matters for coverage
In Wyoming, 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 Sheridan County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Wyoming WSHIIP (State Health Insurance Information Program) gives free, unbiased counseling at (800) 856-4398. Ask which plans serve Sheridan County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Sheridan County ZIP code to see what is offered.
- Medicaid: apply through Wyoming Department of Health.
Wyoming note: Wyoming is one of the few states where the same agency, the Department of Insurance, both regulates the insurance market and runs the state's free Medicare counseling program (WSHIIP) -- most states split those two roles across separate departments.
