Medicare Open Enrollment doesn't cover Medigap
Every fall, Medicare Open Enrollment runs October 15, 2026 through December 7, 2026. That window is for Medicare Advantage plans and Part D drug plans. It does not give you a right to buy or switch a Medicare Supplement (Medigap) policy.
What you can change, and when
| Change | During Oct 15 – Dec 7? | Guaranteed right? |
|---|---|---|
| Join, switch or drop a Medicare Advantage plan | Yes | Yes |
| Join, switch or drop a Part D drug plan | Yes | Yes |
| Switch from one Medigap policy to another | You can apply any time | No, unless you have a guaranteed issue right |
| Leave Medicare Advantage and buy a Medigap policy | You can leave the plan | Only in certain situations |
You can apply for a different Medigap policy at any time of year. The difference is whether the insurance company has to accept you.
Your Medigap Open Enrollment Period
Your best time to buy Medigap is your Medigap Open Enrollment Period. It lasts 6 months, starts the first month you have Part B and are 65 or older, and happens only once. During it, an insurance company can't refuse to sell you any Medigap policy it offers or charge you more because of your health.
After that window closes, Medicare.gov says you may have to answer medical questions and pay more if you switch, unless you have a guaranteed issue right. An insurer can also decline your application.
When you do have a guaranteed right
Federal law gives you a guaranteed issue right in specific situations. The most common:
- Your Medicare Advantage plan leaves Medicare, stops serving your area, or you move out of its service area, and you return to Original Medicare. You can apply from 60 days before your plan coverage ends until 63 days after.
- Your employer or union coverage that pays after Medicare is ending, including retiree and COBRA coverage.
- Your Medigap insurer goes bankrupt or ends your policy through no fault of yours.
In these cases you can usually buy Medigap Plan A, B, D or G, or Plan C or F if you were eligible for Medicare before 2020. Keep the letters or notices that show your coverage is ending, because the insurer may ask for proof. See what happens if your Medicare Advantage plan leaves your area.
North Carolina rules
States can add Medigap rights beyond federal law. The North Carolina Department of Insurance says North Carolina guarantees people under 65 who have Medicare because of a disability the right to buy Medigap Plan A, D or G during their open enrollment period, and they get a new open enrollment period, lasting 6 months, when they turn 65.
For any other North Carolina-specific switching rights, check with the NC Department of Insurance's Seniors' Health Insurance Information Program (SHIIP), the state's free Medicare counseling service, before you cancel a policy.
If you still want to switch
- Apply for the new policy first. Don't cancel your current Medigap policy until the new one is approved.
- Use the 30-day free look. When you're approved, you generally have 30 days to keep both policies before you cancel the old one. You pay both premiums for that month.
- Compare the same plan letter. Plan G from one company covers the same benefits as Plan G from another, so the differences are price and service.
- Look at how premiums are priced and how they may change as you age.

Compare the right type of switch
Changing insurers while keeping the same standardized Medigap letter is different from changing benefits or moving from Medicare Advantage to Original Medicare. Start by identifying your current coverage and the exact change you want. A quote for a new policy is not an approval, and an annual Medicare plan enrollment window is not a substitute for a Medigap guaranteed issue right.
A safe replacement sequence
- Check the right to apply without medical underwriting. Gather any plan termination or other qualifying notice and ask which policies are available under that right.
- Compare like with like. Identify the standardized letter and whether the quote is for a standard or high-deductible version. Review the premium and how the insurer prices future coverage.
- Complete the application accurately. Answer requested health questions truthfully when underwriting applies. Do not cancel existing coverage while an application is being reviewed.
- Obtain the written approval and effective date. Review the policy and any conditions, waiting period or payment requirement.
- Coordinate cancellation. Follow the insurer's instructions so you do not accidentally create a gap or assume the new insurer automatically cancels the old policy.
What if the reason for switching is a premium increase?
Ask for a same-letter comparison before deciding to reduce benefits. A lower initial premium may help, but review how the policy is rated, whether discounts have conditions and how premiums may change. No agent can guarantee future rate increases. Keep the comparison focused on benefits and the actual application requirements rather than a claim that one insurer is always cheapest.
If you have an older policy with benefits you value, ask what would be lost by replacing it and whether you could return later. Do not assume a cancelled policy can be reinstated on the same terms. Also remember that modern Medigap policies do not replace a separate Part D decision.
Documents for a useful review
Bring your Medicare card dates, current Medigap letter, premium notice, insurer name and any coverage-ending letter. If leaving Medicare Advantage, bring that plan's notice too. We can compare available policies and explain the application sequence; the insurer determines acceptance when underwriting applies, and SHIIP can explain North Carolina consumer rights.
Quick questions
Can I change Medigap plans during Medicare Open Enrollment?
You can apply, but Medicare Open Enrollment doesn't give you a right to switch Medigap. Unless you have a guaranteed issue right, the insurer can ask health questions or decline you.
Is there a Medigap birthday rule in North Carolina?
The NC Department of Insurance Medigap guidance we checked doesn't describe one. Check with SHIIP before you count on any state-specific switching right.
Should I cancel my Medigap policy before the new one is approved?
No. Wait until the new policy is approved, then use the 30-day free look before you cancel the old one.
