Why your county matters for coverage
In Arkansas, 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 Sebastian County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Arkansas SHIIP (Senior Health Insurance Information Program) gives free, unbiased counseling at 1-800-224-6330. Ask which plans serve Sebastian County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace, Arkansas state-based exchange oversight); enter your Sebastian County ZIP code to see what is offered.
- Medicaid: apply through Arkansas Department of Human Services (DHS) -- ARHOME.
Arkansas note: Arkansas and Oklahoma are the only two states that run their own state-based marketplace while still using HealthCare.gov's federal technology to enroll people -- a hybrid setup that puts plan approval and rate review in the Arkansas Insurance Department's hands even though the enrollment website itself is federal.
