Usually, no. Whether you already have a Medicare Supplement plan or are considering one, standardized Medigap coverage is generally guaranteed renewable — an insurer normally cannot cancel it because you get sick, file claims, develop a new condition, or grow older. But you can cancel the policy yourself — and getting another one later may require medical underwriting.

The Answer At A Glance
If you get sick or file claims: Your insurer generally cannot cancel your standardized Medigap policy for that reason.
If you stop paying the premium: The policy may terminate after the applicable grace period.
If you cancel the plan yourself: You may have to answer health questions to get another Medigap policy later.
You Are Generally Protected
Getting sick, aging, or filing claims normally does not allow the insurer to cancel a standardized Medigap policy.
Don't Cancel Too Early
Keep your current policy until any replacement coverage is approved and active.
Check Whether You Can Qualify Again
Outside a protected enrollment situation, a new Medigap application may require medical underwriting.
Can a Medicare Supplement plan be canceled?
Yes. You can cancel your Medicare Supplement plan at any time. However, your insurance company generally cannot cancel your standardized Medigap policy as long as you pay the premium and did not materially misrepresent information on your application.
When people ask whether a Medicare Supplement plan can be canceled, they are usually asking one of two very different questions — and the answers point in opposite directions.
A standardized Medigap policy is generally guaranteed renewable. The insurer normally cannot cancel your policy because you got sick, developed a new medical condition, filed expensive claims, used the policy frequently, or grew older. Your policy may still end in limited situations, including nonpayment of premiums or material misrepresentation on the application.
Yes. You can ask the insurance company to cancel your Medigap policy at any time — no waiting for the Annual Enrollment Period. But this is where the larger risk begins: outside your Medigap Open Enrollment Period or another protected situation, replacing that policy later may require medical underwriting. Depending on your health and state rules, a new application could be accepted, priced differently, delayed, or denied.
The Simple Rule
Do not cancel existing Medigap coverage until you understand what will replace it and whether the replacement has been approved.
If you are deciding whether to buy a Medicare Supplement policy, guaranteed renewability is one of its strongest protections. After the policy is issued, the insurance company generally cannot cancel it simply because you become sick, need surgery, develop a chronic condition, file expensive claims, or grow older.
The policy can still end for limited reasons, such as unpaid premiums or material misrepresentation on the application. Premiums may also increase over time, but a rate increase is not the same as cancellation.

See Whether Medigap Fits My NeedsYour insurer generally cannot cancel a standardized Medigap policy because you got sick or filed claims. But premiums can rise, missed payments can cause a lapse, and switching may require medical underwriting. Find the situation below that matches yours:
This page is for people who already have Medigap and are worried about losing it, are considering a switch, or want to understand its protections before enrolling.
The same standardized plan letter may be available from another insurer at a different premium. Whether you can switch depends on your location, health, timing, state protections, and the company's underwriting rules.
See Whether a Lower-Premium Option Is AvailableAct quickly. Check the payment due date, grace-period language, termination date, and whether the insurer will accept payment or consider reinstatement. Do not assume the policy is permanently lost — or that it can automatically be restored.
Call With Your Notice in HandAnother insurer may offer the same standardized plan letter at a different premium. Apply for the replacement first and confirm whether medical underwriting applies before canceling your current policy.
Check If I Can Switch CompaniesA lower monthly premium may be attractive, but Medicare Advantage works differently from Original Medicare with Medigap. Before dropping Medigap, review networks, prescriptions, copays, maximum out-of-pocket exposure, and whether returning to Medigap later could require underwriting.
Review the Tradeoffs Before I SwitchOne of Medigap's most important protections is guaranteed renewability. Once a standardized policy is issued, the insurer generally cannot cancel it because your health changes, you file claims, or you use the coverage heavily — as long as premiums are paid and the application information was accurate.
Compare Medicare Supplement Options Before I EnrollWhat Your Medicare Supplement Review Includes
Bring us your current plan, premium, and reason for considering a change. We will help you determine what can be changed, whether medical underwriting may apply, and what should stay in place until replacement coverage is confirmed — even when keeping your current plan is the better choice.
No separate consultation fee. Availability, premiums, underwriting, and eligibility vary by insurer, location, health history, timing, and state rules.
Start My Medicare Supplement ReviewYou can ask the insurer to cancel your Medigap policy at any time, but canceling before replacement coverage is approved can create a serious coverage problem. When replacing one Medigap policy with another, apply first and keep the current policy active until the replacement is approved and effective. You may temporarily pay both premiums during the review period.
Apply first. Get the new Medigap policy approved before touching your current one.
Wait for written approval and the effective date. Verbal or preliminary confirmation is not enough.
Cancel the old policy only after confirming the replacement is active and acceptable. Use the free-look period to make sure.

Make Sure I'm Covered Before I SwitchFederal law generally prohibits insurers from canceling or non-renewing a standardized Medigap policy. There are, however, a small number of legitimate situations where cancellation can occur.
The policy may terminate after the applicable grace period if premiums remain unpaid.
An insurer may rescind or terminate coverage when material application information was intentionally false or misleading, subject to applicable law.
If coverage ends through no fault of your own, you may have protected rights to obtain another Medigap policy.
The Key Protection
What insurers cannot do is drop you just because you got sick, aged, or used the coverage. That protection is the entire point of guaranteed renewability.
No. A standardized Medigap policy generally cannot be canceled because you became sick, filed expensive claims, or used the coverage heavily.
Dropping Medigap for Medicare Advantage can reduce monthly premiums, but it may also change doctor access, copays, drug coverage, and out-of-pocket exposure. Returning to Medigap later may require medical underwriting unless a protected right applies.
It is worth walking through the tradeoffs first. There is no pressure and no obligation.
Guaranteed issue rights — sometimes called "Medigap protections" — are special protections that may allow you to buy certain Medicare Supplement plans without going through medical underwriting. If you qualify, an insurer cannot deny you coverage or charge you more based on your health history.
Situations that may trigger guaranteed issue rights include:
Different but Also Important
Your initial six-month Medigap Open Enrollment Period is a separate protection during which insurers generally cannot use medical underwriting based on your health.
No. A standardized Medicare Supplement policy cannot be canceled because you become ill, develop a new health condition, or use your coverage. Medigap policies are guaranteed renewable under federal law. As long as you pay your premiums and were truthful on your application, your insurer cannot drop you for health reasons.
No. A standardized Medigap policy cannot be canceled because of high claims usage. Even if you have cancer, need surgery, or have repeated hospital stays, the insurance company cannot cancel your policy just because the claims are expensive. That protection is one of the core features of Medicare Supplement coverage.
Yes. You can voluntarily cancel a Medicare Supplement plan at any time. You do not need to wait for the Medicare Annual Enrollment Period. Contact your insurance company to request the cancellation and ask for written confirmation. Before you cancel, make sure you understand what it would take to get new Medigap coverage later, because medical underwriting may apply.
No — this is one of the most common mistakes people make. Apply for the new plan first. Wait for written approval. Then use the 30-day free look period to temporarily overlap both policies before finalizing the cancellation. If you cancel first and then something goes wrong with the new application, you could end up without Medigap coverage entirely.
It depends. Outside of your initial 6-month Medigap Open Enrollment Period or a qualifying guaranteed issue situation, an insurance company may require you to go through medical underwriting. Depending on your health, you could be approved, charged more, delayed, or declined. Some states have birthday rules or anniversary rules that allow limited switching without underwriting. Getting your coverage back is not guaranteed — which is why canceling carefully matters.
If you stop paying your Medicare Supplement premium and the grace period passes, the insurance company can terminate the policy for non-payment. Most policies include a grace period, but the exact rules can vary by policy and state — check your policy documents or call the insurance company before assuming you still have time to pay. If the policy lapses, you may need to go through medical underwriting to obtain new coverage unless you qualify for guaranteed issue rights. Set up automatic payment if you are concerned about missing a due date.
Yes, but it is a significant decision. Medicare Advantage and Medicare Supplement are different types of coverage with different rules, networks, and cost structures. If you drop a Medigap plan to enroll in Medicare Advantage and later want to switch back, you may face medical underwriting. There is no guarantee you will be able to re-enter Medigap at the same price or at all. Talk with a licensed advisor before making this switch.
A standardized Medigap policy is generally guaranteed renewable. The insurer normally cannot cancel it because your health changes, you file claims, or you grow older. You must continue paying the premium, and the application information must be accurate. Premiums may increase, but an increase is not the same as cancellation.
