Tornadoes, Ice Storms and Your Medicare in Oklahoma

Quick answers

Do I get a special enrollment period after an Oklahoma tornado?

Only if a government declared an emergency or disaster where you live and it kept you from using another enrollment period you were eligible for. It lasts until 2 full calendar months after the declaration ends.

Will Medicare pay for a generator?

Don't count on it. Medicare's equipment benefit covers items that serve a medical purpose, and Medicare equipment contractors say backup batteries for equipment that runs on wall power aren't covered. Ask your electric company about its rules for customers with medical needs.

How do I replace a Medicare card lost in a storm?

Print or order an official card in your Medicare.gov account, or call 1-800-MEDICARE. For a Medicare Advantage or Part D card, call your plan.

Who helps dialysis patients in an Oklahoma emergency?

ESRD Network 13, which serves Oklahoma, Arkansas and Louisiana, helps Original Medicare patients find treatment, supplies and transportation. Its patient line is 1-877-886-4435. With a Medicare Advantage plan, call the plan too.

Does my Medicare Advantage plan cover out-of-network care after a disaster?

When the President, the HHS Secretary or the Governor declares a disaster and it disrupts the plan's network, the plan must cover non-network facilities at in-network cost sharing until 30 days after the declarations end or the disruption is over, whichever comes first.

Why Oklahomans on Medicare need a storm plan

Oklahoma's disasters come in every season. FEMA's records show these recent federal major disaster declarations for the state:

• October 2020 ice storm (DR-4575): a severe winter storm from October 26 to 29, 2020, declared December 21, 2020, for 29 counties, including Oklahoma, Cleveland, Canadian and Comanche counties.
• February 2021 winter storms (DR-4587): severe winter storms from February 8 to 20, 2021, declared for all 77 counties.
• Spring 2024 tornadoes (DR-4776): severe storms, tornadoes and flooding from April 25 to May 9, 2024, declared April 30, 2024, for 25 counties, including Murray, Love, Pottawatomie and Osage counties.
• November 2024 storms (DR-4862): severe storms, tornadoes and flooding from November 2 to 5, 2024, declared March 18, 2025, for eight counties, including Oklahoma County.
• March 2025 wildfires (DR-4866): wildfires and straight-line winds that began March 14, 2025.
• July 2026 storm (DR-4950): a severe storm and straight-line winds on July 4, 2026, declared October 7, 2026, for Cleveland, Nowata, Osage and Washington counties.

Each kind of disaster hits older adults in its own way. Tornadoes destroy homes, medicines and Medicare cards in minutes. Ice storms can leave people without power for days, which matters if you use oxygen or other electric equipment. Medicare has special rules for declared emergencies, and knowing them ahead of time makes them easier to use.

Can I change my Medicare plan after a tornado or ice storm?

Sometimes. Federal rules at 42 CFR 422.62(b)(18) (Medicare Advantage) and 42 CFR 423.38(c)(23) (Part D), as they read in November 2026, create a special enrollment period for people affected by an emergency or major disaster declared by a federal, state or local government. You qualify if all of these are true:

• You live in the area the declaration covers, or lived there when the period began, or you rely on someone there to help with your health care decisions.
• You were eligible for another enrollment period during the disaster, such as Medicare Open Enrollment (October 15 to December 7) or your Initial Enrollment Period.
• You didn't use that enrollment period because of the disaster.

The special enrollment period starts on the date the declaration is made, the incident start date, or the start date in the declaration, whichever is earliest. It ends 2 full calendar months after the end date in the declaration. If no end date is ever set, the incident is treated as ending one year after the period starts (or at a later renewal), and the period can't run longer than 14 full calendar months. Medicare.gov adds that, with Original Medicare, a similar special enrollment period may let you sign up for Part B if a declared emergency kept you from doing so.

The storm by itself doesn't give you a new chance to switch. If you missed Open Enrollment because of a declared disaster, call 1-800-MEDICARE and say so. See Medicare enrollment periods.

Does my Medicare Advantage plan have to cover out-of-network care in a disaster?

When a disaster or emergency is declared and it disrupts your access to your plan's doctors and hospitals, yes. Under 42 CFR 422.100(m), a Medicare Advantage plan must:

• Cover Part A and Part B services, and the plan's supplemental benefits, at facilities that aren't in its network.
• Charge you the same cost sharing as if the facility were in network.
• Waive referral requirements.
• Make changes that help you right away, without the usual 30-day notice.

These rules apply to declarations by the President (under the Stafford Act or the National Emergencies Act), a public health emergency declared by the HHS Secretary, or a declaration by the Governor of Oklahoma. They last until 30 days after all the declarations for your area end, or until the plan's network is working normally again, whichever is earlier. A county or city declaration alone does not trigger them, though it can still create the special enrollment period above.

What if my doctor's office or hospital closes after the storm?

If a doctor or clinic in your Medicare Advantage plan's network leaves the network, federal rules (42 CFR 422.111(e)) require the plan to send you written notice: at least 45 days ahead for a primary care or behavioral health provider you've seen in the past three years, and at least 30 days ahead for a specialist you see regularly. A building destroyed by a tornado is different: call your plan's member services number to find another network provider, and ask whether the disaster rules above apply.

With Original Medicare, you can see any doctor or hospital in the country that accepts Medicare, so a storm doesn't change where you can go. A Medigap policy follows you too.

How do I replace or refill prescriptions after a storm?

Call your Part D or Medicare Advantage drug plan as soon as you can. Medicare.gov says your plan can help you replace drugs that were lost or damaged, including ones you couldn't bring when you evacuated, and you can ask for a 60- or 90-day supply if you expect to be away from home for a long time.

• Check your plan's rules before using an out-of-network pharmacy. You'll probably pay full price there, so keep the receipt and ask the plan to repay its share. You may still owe the difference between out-of-network and in-network prices.
• Before tornado season, ask your plan whether you can get a 90-day supply of the medicines you take every day.
• Keep a written list of your medicines, doses and doctors in a waterproof bag in your storm shelter or safe room, with a photo on your phone.

Medicare.gov also reminds you that premiums are still due during a disaster. Having your premium taken from your Social Security check, or paying by automatic bank transfer, keeps coverage going if mail stops.

How do I replace my Medicare card?

With Original Medicare, log in to (or create) your secure account at Medicare.gov to print or order an official card, or call 1-800-MEDICARE (1-800-633-4227; TTY 1-877-486-2048). If you have a Medicare Advantage or Part D plan, call the plan for a new member card. Take a photo of the front of each card now, so you have the numbers if the cards are lost.

What happens to my oxygen, wheelchair or other equipment?

With Original Medicare, Medicare generally covers repair or replacement of durable medical equipment (DME) that was lost or damaged in a disaster, such as wheelchairs, walkers and diabetic supplies, but only when you get it from a Medicare-approved supplier. It may also cover a rental while yours is being repaired. If you have Medicare Advantage, call your plan about its replacement process.

If your equipment needs electricity

Ice storms are the bigger threat to people who use oxygen concentrators, CPAP machines, power wheelchairs or other electric equipment, because outages can last for days. Plan for power before the storm:

• Medicare doesn't pay for backup power. Medicare covers equipment that serves a medical purpose, and a Medicare equipment contractor's coverage article says power adapters and backup batteries for equipment that can run on wall power are denied as not medically necessary. It tells people who need uninterrupted power for medical equipment to contact their power company. Don't count on Medicare to pay for a home generator.
• Ask your supplier what backup tanks or batteries you should keep, how long they last, and how the supplier will reach you if the power is out.
• Know Oklahoma's utility rule. Under Oklahoma Corporation Commission rule OAC 165:35-21-10(f), a licensed medical doctor or osteopath can certify that a disconnection would be life-threatening for someone in your household. That suspends a shutoff for nonpayment for 30 calendar days, with one possible 30-day extension. You still owe the full bill. This rule is about shutoffs for unpaid bills; it does not keep power on during a storm outage.
• Tell your electric company that someone in your home depends on electric medical equipment, and ask what it offers those customers. Have a plan to go somewhere with power, such as a relative's home, if an outage lasts.

I get dialysis. What should I plan for?

Dialysis can't wait for the roads to clear. With Original Medicare, your End-Stage Renal Disease (ESRD) Network can help you keep getting treatment and find supplies, drugs, transportation and emergency financial help. Oklahoma is served by ESRD Network 13, which also covers Arkansas and Louisiana. Its patient line is 1-877-886-4435. If you have a Medicare Advantage plan, call the plan to find a dialysis facility and learn which rules change during the emergency.

Ask your dialysis center now for its emergency plan, a backup location, and the emergency diet to follow if you miss a treatment.

Where else can I get help after a disaster?

• FEMA: apply for disaster assistance at DisasterAssistance.gov or call 1-800-621-3362 when your county is in a federal declaration that includes help for individuals.
• 1-800-MEDICARE (1-800-633-4227; TTY 1-877-486-2048): plan contacts, enrollment changes and equipment questions.
• Your plan: the member services number is on your plan card.
• Scams after storms: FEMA never charges a fee to apply or for an inspection. See Medicare fraud in Oklahoma.
• Rural hospitals: if your nearest hospital has changed, see rural hospitals and telehealth in Oklahoma, and Oklahoma Medicare contacts for official phone numbers.

An Oklahoma storm-season checklist

1. Pack a medicine kit. Put your medicine list, doctors' names and a few days of medicines in a waterproof bag you can grab on the way to your shelter.
2. Photograph your cards. Take pictures of your Medicare, plan and Medigap cards and keep them on your phone.
3. Ask about longer supplies. Ask your drug plan whether you can get 90-day supplies of your regular medicines before spring tornado season and winter ice storms.
4. Plan for power. Get backup instructions from your oxygen or equipment supplier, tell your electric company about your medical needs, and decide where you would go during a long outage.
5. Plan for dialysis. Get your dialysis center's emergency plan and save ESRD Network 13's patient line, 1-877-886-4435.
6. Review your coverage. Know which plan you have and whether its network reaches the places you would go in an emergency. To review plans from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code.
