Moving to Oklahoma With Medicare

What moves with me, and what doesn't?

Original Medicare: update your address

Original Medicare is a federal program, so your Part A and Part B coverage and your Medicare card don't change when you move. Tell Social Security your new address, online with a my Social Security account or by calling 1-800-772-1213 (TTY 1-800-325-0778), so your Medicare notices and Medicare Summary Notices reach you. If you get Railroad Retirement Board benefits, tell the RRB instead.

Medicare Advantage and Part D: your moving special enrollment period

Medicare Advantage and Part D plans have service areas. In Oklahoma, Medicare Advantage plans are approved county by county, and for 2027 CMS lists 50 plans open to everyone statewide and 9 standalone Part D plans. When you move to a place your plan doesn't serve, you get a special enrollment period:

• If you tell your plan before you move, your chance to switch starts the month before the month you move and lasts 2 full months after the month you move.
• If you tell your plan after you move, your chance to switch starts the month you tell the plan and lasts 2 more full months.
• If you move within Oklahoma to a county your plan doesn't serve, the same rules apply. If your plan does serve your new county but offers new options there, you can also switch.
• If you're moving back to the U.S. after living abroad, you can join a plan during the 2 full months after the month you move back.

1. Call your current plan. Ask whether it serves your new Oklahoma address and when your coverage would end.
2. Look up your new county. Plan choices vary widely across Oklahoma; see our counties page.
3. Check networks and drugs. Confirm your new doctors, hospital and pharmacy are in the plan's network, and your drugs are on its list.
4. Enroll within your window. Choose a Medicare Advantage plan or a Part D plan before your special enrollment period ends.

Medigap: can I keep it?

Usually yes. A standard Medigap policy stays in force anywhere in the U.S. as long as you pay the premium, though your premium may change because prices depend on where you live. A few things to know:

• Medicare Select: if your policy requires you to use certain hospitals and doctors and you move out of its area, you have the right to buy another Medigap policy, and you may need to switch.
• Leaving Medicare Advantage because of the move: moving out of your plan's service area gives you a guaranteed right to buy Medigap Plan A, B, D, G, K or L (or C or F if eligible for Medicare before 2020), applying up to 63 days after your plan coverage ends.
• Oklahoma's birthday rule: once you're an Oklahoma resident, you can switch to a Medigap policy with the same or fewer benefits, from any company, without health questions, during the 60 days that start on your birthday each year. The Oklahoma Insurance Department says it doesn't matter which state you bought your policy in, as long as you live in Oklahoma and meet the rule (OAC 365:10-5-129(f)). You must have had no break in Medigap coverage longer than 90 days.

Plan K and L out-of-pocket limits and other Medigap amounts are federal and don't change with your state: for example, Plan K's limit is $8,360 in 2027. See Medigap in Oklahoma.

Medicaid doesn't transfer: apply for SoonerCare

Medicaid is run by each state, so your Medicaid or Medicare Savings Program from another state ends when you move. In Oklahoma, Medicaid is SoonerCare, run by the Oklahoma Health Care Authority (OHCA). SoonerCare Supplemental includes the Medicare Savings Programs (QMB, SLMB and QI-1), which can pay your Part B premium and, for QMB, Medicare cost sharing. OHCA says to apply at your local Oklahoma Human Services office, or download the Request for Benefits form from OKDHS's forms site and send it to your local office. The SoonerCare Helpline is 1-800-987-7767. Getting or losing Medicaid gives you a special enrollment period for Medicare plans. See SoonerCare and Medicare and Medicare Savings Programs in Oklahoma.

Permanent move or part-year stay?

Medicare Advantage plans are tied to your permanent home. If you keep your home in another state and only spend part of the year in Oklahoma, a Medicare Advantage plan from home may cover only emergency and urgent care here, and a plan must disenroll you if you're away from its service area for more than 6 months in a row (unless it has a visitor program). Original Medicare with Medigap works with any provider in the U.S. who accepts Medicare. See Medigap vs. Medicare Advantage in Oklahoma.

Retirees, veterans and tribal citizens

• Employer or retiree coverage from another state: ask your plan whether it works in Oklahoma. If you're joining an Oklahoma public employer's plan, see state and teacher retirees and Medicare.
• Veterans: transfer your VA care to an Oklahoma VA facility, and check how TRICARE For Life works with your new providers. See veterans, TRICARE and military retirees.
• Tribal citizens: IHS and tribal health systems in Oklahoma set their own eligibility rules. See tribal health and Medicare in Oklahoma.

Finding doctors in Oklahoma

Use Medicare's Care Compare to search for doctors, hospitals, nursing homes and other providers near your new ZIP code. Ask new doctors whether they accept Medicare assignment. Many rural Oklahoma communities rely on small hospitals and telehealth, and some patients travel to Oklahoma City, Tulsa or a city across the state line for specialty care; see rural hospitals and telehealth in Oklahoma. Oklahoma also has tornado and ice storm seasons; keep a list of your prescriptions and plan contacts, and see tornadoes, ice storms and Medicare.

Your moving checklist

1. Tell Social Security your new address. Online or at 1-800-772-1213.
2. Call your Medicare Advantage or Part D plan. Ask whether it serves your new Oklahoma county.
3. Pick a new plan during your special enrollment period, if you need one.
4. Ask your Medigap company whether your policy or premium changes, and note your birthday window.
5. Apply for SoonerCare if you had Medicaid or a Medicare Savings Program in your old state.
6. Find new doctors and a pharmacy, and move your prescriptions.

To see plans for your new address, see plans for your ZIP code, or you can request a call from a licensed insurance agent to go over plans from the companies they work with, at no cost to you. You can also meet licensed insurance agents in Oklahoma.
