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).

Why your county matters for coverage
In Oklahoma, 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 Adair County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Oklahoma SHIP (State Health Insurance Counseling Program) gives free, unbiased counseling at 1-800-763-2828. Ask which plans serve Adair County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Adair County ZIP code to see what is offered.
- Medicaid: apply through SoonerCare (Oklahoma Health Care Authority).
Oklahoma note: Oklahoma expanded Medicaid relatively recently, in July 2021, following a 2020 statewide ballot measure -- worth knowing since older information about Oklahoma Medicaid eligibility may predate that expansion and understate who currently qualifies.
