How to use these comparisons
- Start with what you already have. If you have SoonerCare, IHS or tribal care, or HealthChoice retiree coverage, read that comparison first, because it can change which Medicare choice makes sense.
- List your doctors, hospitals and drugs. Check whether each one works with the coverage you're considering, including the hospital you'd be transferred to from a rural emergency room.
- Check the deadlines. Open Enrollment runs October 15 to December 7, 2026, for 2027 coverage. See Medicare enrollment periods.
- Get help if you want it. To compare plans from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code.

Frequently asked questions
What is the main Medicare choice in Oklahoma?
Whether to use Original Medicare, usually with a Medigap policy and a Part D drug plan, or a Medicare Advantage plan. Original Medicare works with any provider in the country that accepts Medicare, while most Medicare Advantage plans use networks. For 2027, CMS data show 50 Medicare Advantage plans open to everyone across Oklahoma, and seven counties have none.
Can I have SoonerCare and Medicare at the same time?
Yes. People who qualify for both are called dual eligibles. Medicare pays first, and SoonerCare can help with costs Medicare leaves, depending on the level of SoonerCare you qualify for. The Oklahoma Health Care Authority runs SoonerCare.
Do I need Medicare if I get care through IHS or a tribal health system?
Medicare and IHS are different. IHS and tribal health programs are not insurance, and Medicare can pay IHS, tribal and urban Indian health facilities for covered care you get there. Enrolling in Medicare when you're eligible can also cover care outside those facilities. Ask your clinic how it works with Medicare.
Where do I compare HealthChoice retiree coverage with other Medicare options?
HealthChoice retiree coverage is run by the Employees Group Insurance Division of the Office of Management and Enterprise Services (OMES/EGID). Read our HealthChoice retiree comparison, and call EGID Member Services at 1-800-752-9475 for eligibility questions before you drop or change retiree coverage, because you may not be able to get it back.
