What happens to each kind of coverage
| Your coverage | After you move to Oklahoma | What to do |
|---|---|---|
| Original Medicare (Parts A and B) | Works the same with any provider in the U.S. that accepts Medicare | Update your address with Social Security |
| Medigap policy | Keeps paying its share; it isn't tied to a service area | Tell the company your new address; premiums may change |
| Medicare Advantage plan | Usually no longer covers you if Oklahoma is outside its service area | Choose an Oklahoma plan during your special enrollment period |
| Part D drug plan | Standalone plans are sold by region; you may need a new one | Check whether your plan serves Oklahoma |
Steps for your move
- Tell your plan before you move. If you tell a Medicare Advantage or Part D plan ahead of time, your special enrollment period starts the month before your move and runs two full months after.
- Pick a plan for your new county. Oklahoma choices differ by county. CMS data show 50 Medicare Advantage plans open to everyone in the state for 2027, but seven counties in the Panhandle and western Oklahoma (Beaver, Cimarron, Ellis, Harmon, Harper, Roger Mills and Texas) have only special needs plans. See Oklahoma counties.
- Check your doctors and drugs. Look up your new Oklahoma doctors and pharmacy in a plan's directory before you join. See can I keep my doctor.
- Update your address. Social Security keeps your Medicare address.
Medigap after the move: Oklahoma's birthday rule
Your Medigap policy goes with you. Once you live in Oklahoma, you also get the state's birthday rule: under Oklahoma Insurance Department rule OAC 365:10-5-129, each year for 60 days starting on your birthday, you can switch to a Medigap policy with equal or lesser benefits without health questions, if you haven't gone more than 90 days without Medigap. The Insurance Department says it doesn't matter which state you bought your policy in. See Medigap in Oklahoma.
Help paying costs
If you had Medicaid or a Medicare Savings Program in your old state, apply again in Oklahoma. OKDHS says you can visit or call your OKDHS Human Services Center to apply for help paying Part A and Part B premiums. See SoonerCare and Medicare.
Get help
A licensed insurance agent who works with Benefits Life can compare Oklahoma plans from the companies they work with for your new county, at no cost to you. You can request a call from a licensed insurance agent, or see plans for your ZIP code. For the full guide, see moving to Oklahoma with Medicare.

Frequently asked questions
Do I need a new Medicare card when I move to Oklahoma?
No. Your Medicare card and number stay the same. Update your address with Social Security online, by phone at 1-800-772-1213, or at an office, so your mail and any premium bills reach you.
What if I don't pick a new Medicare Advantage plan in time?
If you move out of your plan's service area and don't join a new plan, you'll be enrolled in Original Medicare when your old plan drops you. You may then be without drug coverage until you join a Part D plan.
Does my Medicaid move with me to Oklahoma?
No. Medicaid and the Medicare Savings Programs are run by each state. After you move, apply in Oklahoma through your OKDHS Human Services Center or SoonerCare, and close your case in your old state.
