Can I change my Supplemental/Medigap plan at any time?

Question

Gregg Matheny · Accepted Answer

Medicare Supplement plans can be changed anytime, however, they may be subject to underwriting depending upon the time period that you’re trying to enroll.

Larry Dalton · Answer

Yes, at any time. However, you may require medical underwriting approval. Except for the three months before your 65th birthday month, the month of your 65th birthday, three months after your 65th birthday, or 63 days after working past 65 with a company group insurance plan of 20 or more. Then there are no medical underwriting requirements within those timelines.

Yes you can-however once enrolled in a Supplemental/Medigap plan and you want to change -most companies will require you to be "medically qualified" by answering the medical questions on the new application! PS Always look for companies that are Financially Stable!

William Lawler · Answer

Yes, you can change your Medigap plan at any time, but you will be subject to underwriting and health questions. However, if you wait until the anniversary month of when your Medigap plan became effective, you may switch plans with no underwriting or health questions.

Technically yes, but it depends on your state’s rules. In most states, you can apply anytime — but you may have to answer health questions and could be denied. Some states have more flexible rules, so it’s worth checking.

Charles Fletcher · Answer

Yes, in Washington State, you can change your Medicare Supplemental (Medigap) plan at any time during the year, but there are specific rules depending on your current plan. Unlike most states, Washington has a unique "Right to Change" law that offers year-round guaranteed issue for existing Medigap policyholders, meaning you can switch plans without medical underwriting in certain cases. Here’s how it works:

If you have Medigap Plan A: You can only switch to another Plan A offered by a different insurer without undergoing medical underwriting. You’re limited to staying within the same plan letter.

If you have Medigap Plans B through N: You can switch to any other plan between B and N (e.g., from Plan G to Plan N, or Plan B to Plan F) at any time, also without medical underwriting. This gives you more flexibility to adjust coverage or premiums.

Key Conditions: You must already be enrolled in a Medigap plan to use this rule. If you’re coming from Original Medicare alone or a Medicare Advantage plan, you can’t switch to a Medigap plan under this guaranteed issue provision—you’d need to apply normally, which might involve health questions outside your initial 6-month Medigap Open Enrollment Period or a Special Enrollment Period.

Practical Steps: To switch, contact the new insurance provider, apply for the desired plan, and, once approved, cancel your old plan. There’s no specific enrollment window like the Annual Enrollment Period (October 15–December 7) that applies to Medicare Advantage or Part D—Washington’s rule lets you do this anytime.

This flexibility is a big perk in Washington compared to most states, where switching outside specific periods often requires passing medical underwriting, risking denial or higher rates due to health conditions. Just make sure the new plan fits your needs—compare benefits and premiums carefully with your Medicare Insurance broker, as costs can vary by insurer even for the same lettered plan.

Ray McCauley · Answer

If you can pass underwriting. Other than that you can only change upon your birth month if you reside in a birthday rule state.

Bryan Smith · Answer

Yes! As long as you can pass underwriting in some situations. Also depending on where you live or where you signed up, you may not be required to answer health questions.

Shawn Brown · Answer

Yes. However, for approval, you'll likely be subject to medical underwriting questions. If you have a perfect bill of health you can change anytime. If not, you'll likely be declined.

Justin Sonon · Answer

Contrary to popular belieft, Medigap plans can be changed throughout the year. You can also change them when moving to a different state throughout the year if desired.

Phillip Lovelady · Answer

You can cancel your Supplement/Medigap plan at any time of the year. You don't need to wait for an enrollment period. Once you have been on Medicare Part B for over a year with your Supplement, you would have to answer health questions and qualify medically in order to qualify for a new policy. Medicare beneficiaries usually look to change plans when their current premiums have increased, and want the same plan but with lower premiums.

Jolynn Allen · Answer

It depends on what you are changing to. Can you switch from one Medicare Supplement to another at anytime - yes you may, but there will most likely be underwriting involved. Outside of turning 65 or leaving employer group health insurance there are few opportunities to change a Medicare supplement without being asked health questions. If you do not have health issues changing plans can be very easy. 

If you are wanting to change from a Medicare Supplement to a Medicare Advantage plan, that needs to occur during the Annual Enrollment Period from October 15th to December 7th each year.

Colleen Williams · Answer

Yes, you can switch or drop a Supplemental/Medigap plan at any time, but be aware that there may be restrictions and potential waiting periods for pre-existing health conditions. Insurers may consider your health status when deciding whether to sell you a plan and how much it will cost.

Patrick Bullock · Answer

One of the reasons people like Medicare Supplement plans is that you can change that supplement to another any time of the year. Medicare Advantage plans have enrollment periods the you must abide by, and generally are required to stay in that plan for the entire year. That being said, after the initial enrollment period ends, a person's application will go through underwriting and they must be able to answer those health questions to the satisfaction of the particular insurance company.

Greg Milliser · Answer

The answer is “Yes, you can.” HOWEVER, there are qualifications that must be met before the change can go into effect. In order to change any time during the year you must answer underwriting questions about your health history and have no disqualifying conditions. If this condition is met the policy will go into effect.

Frank Buonomo · Answer

You are able to change your Medicare supplement plan at any time, but you will need to qualify through underwriting. Your health will determine if you qualify for another plan. Some states have special enrollment periods sometimes known as the birthday rule. If you live in a state that offers these periods, you will have a time window around 60 days from your birthday to change your supplement without underwriting.

Shane Bullock · Answer

You can apply at any time, but you may not be accepted at any time. Medicare supplement (Medigap) plans do not have a nationwide yearly enrollment period like Medicare Advantage (Part C) or standalone Prescription Drug (Part D) Plans do. 

Rules do vary from state to state, but in general, there is a one-time Open Enrollment period for Medigap plans - this is the first 6 months after your Part B effective date. In this 6-month period, you can enroll in any Medigap plan you want regardless of your health. After this period, you will most likely have to go through underwriting (i.e. answer questions about your health history) to enroll in a Medigap plan. If you have a serious health condition, you may not qualify. Find a competent agent/broker to help you with this process because each insurance company has their own rules for what they will accept or deny.


Some states have guaranteed issue (i.e. you must be accepted regardless of your health) rules such as a birthday rule, which will give people an opportunity to change plans yearly. Check with an agent/broker to see if you have that opportunity in your state.

You may change your supplemental/medigap plan, 12 months out of the year. You are not bound by the Annual Enrollment Period in the fall, if you’re looking to move from one supplemental plan to another, for example moving from an Aetna G Plan to a Cigna G Plan.

Diana Garner · Answer

The short answer is "yes, you can."  Medicare Supplements are not like Medicare Advantage Plans. Medicare Supplement policies are underwritten by the insurance company, and each company has different underwriting guidelines.

For a Medicare Supplement plan, after your initial enrollment, you would have to medically qualify to change plans, and by that, I mean that you would have to be healthy enough to make it through underwriting.  If you do not medically qualify, some states have guaranteed issue periods called the Birthday Rule, where you can change your Medigap plan within the 60 days following your birthday each year to get lower premiums.

Leslie Helene Sussman · Answer

No there is no yearly Annual Enrollment for Medicare Supplement/Medigap like there is for Medicare Advantage/RX Plans.

Typically, Medical Underwriting/review is necessary to change plans.   If you are looking to lower premium discuss your options with a Medicare broker.

Underwriting review consists of medical questions, Prescription list, Height/Weight etc.

Steve Houchens · Answer

You may but you will be subject to going through underwriting if you aren't in a guaranteed issue period and you could be subject to higher premiums or the possibility of being declined

Sean Davis · Answer

You can change your Supplemental or Medigap plan, but doing so may depend on certain conditions. If you are within your Medigap Open Enrollment Period, which lasts for six months after you turn 65 and enroll in Medicare Part B, you can switch plans without medical underwriting. Outside of that period, you may need to provide health information and go through underwriting, which could affect your ability to obtain coverage.

Additionally, some states have specific rules regarding changes. It’s crucial to review your current plan, understand the options available, and check for any open enrollment periods to make changes without complications.

David Koller · Answer

Yes and possibly no...it depends on your situation.  Are you eligible for a guarantee issue period or could you be underwritten? We can discuss and determine to see what your options are.

Robert Helmkamp II · Answer

Technically Yes, you may change your Supplemental/Medigap plan at anytime throughout the year. Unless you are approved for Guaranteed Issue and if you are outside of the 6 month Medigap Open Enrollment Period, which is the first six months after you become eligible for Medicare and enroll in Part B, then you will be subject to medical underwriting.  Medical Underwriting factors in your current age, current health status, and any pre-existing conditions. Then the company will either deny coverage due to these factors or issue a policy with a premium that reflects the Medical Underwriting.

MEDIGAP OPEN ENROLLMENT PERIOD: If you enroll in a Medigap/Supplemental plan within the first six months after turning 65, you will be approved for almost any Medigap Policy at the lowest price, regardless if you have pre-existing conditions or health problems.

GUARANTEED ISSUE: Means you can switch Medigap/Supplemental Plans without Medical Underwriting. This only applies to certain situations, like moving out of plan's service area or losing employer sponsored coverage. In very rare occurrences, a company may offer Guaranteed Issue for their Medigap Plans during Annual Enrollment Period.

Marcy Bulliner · Answer

Supplemental / Gap insurance can be changed at any time of the year. However anytime you change from one to plan to another (even within the same company) there are going to be health questions you must answer. Usually these health questions limit your availability of getting new or different coverage if you have health concerns. That is why is it important to choose the right level of coverage when you first become eligible for part B, because during that time there are no health questions

Fred Manas · Answer

Yes, you can typically switch your Supplemental (Medigap) plan at any time, but it's not always guaranteed. You can apply to change your plan at any time, but the insurance company may decline your application or impose certain conditions, especially if you don't have a guaranteed issue right. 
Elaboration:
Guaranteed Issue Rights:
If you have a guaranteed issue right (usually during your Medigap open enrollment period or if you switch from Medicare Advantage), the insurer must accept your application without considering your health status. 
Outside of Guaranteed Issue:
Outside of guaranteed issue periods, you may be subject to medical underwriting, meaning the insurer can deny your application or charge higher premiums based on your health history. 
State Regulations:
Some states have special rules that may make it easier or harder to switch plans, so it's important to check with your state insurance department. 
New York Specifics:
In New York, insurers must sell you any Medigap policy at any time, regardless of pre-existing conditions. 
Impact of Pre-existing Conditions:
If you switch to a new Medigap plan, you may have to wait up to six months for the new policy to cover pre-existing conditions. 
Dropping Your Medigap Plan:
If you choose to drop your current Medigap plan, you may not be able to get another one in the future.

Steve Brauer · Answer

You can change your MediGap plan at any time, but you will most likely have to go through underwriting. That means that depending on how you answer health questions, the carrier can deny you coverage.

Kelly Linster · Answer

The short answer is yes. However you will have to go through medical underwriting (health questionnaire) to determine eligibility to change. A handful of states have a birthday rule where you can switch without underwriting.

Sonya Chandler · Answer

Yes, you can change Supplemental/Medigap plans anytime through out the year.  You can go from one Supplemental/Medigap Plan to another.

Barbara Barnes, CMIP® · Answer

Technically, yes.  Medicare Supplement plans are not locked-in to an annual cycle like Medicare Advantage and Medicare Part D plans. This means that you can make changes to them at any time of the year.

BUT outside of the Initial Enrollment Period (when you're new to Medicare Part B), or a Special Enrollment Period, you will need to qualify through Medical Underwriting to make a change in Medicare Supplement insurance plans or companies.  If you've recently been in the hospital, have medical tests or treatment pending or you have a chronic condition or use a lot of medications, you can be denied coverage.  This is why it's important that you never cancel one policy without first having the new policy that you're replacing it with in place.  Many clients have questioned this because the Affordable Care Act eliminated pre-existing conditions and made it so that people with pre-existing conditions could get insurance, but that law does not specifically apply to Medicare programs.  It is possible that this could change in the future, but for now, Supplement plans are still medically underwritten and can be denied.

Kris Neupauer · Answer

The Quick answer is yes. You should shop your Medicare supplemental plans every year because plan level to plan level the coverage is the same it's just the difference of what the insurance companies will charge you. But you cannot change your plan level to be clear at any given time that's important to note.

Yes, you can change your Medigap plan anytime, but depending on your state, you might have to go through medical underwriting.

California has a birthday rule, which gives you 60 days after your birthday each year to switch to a plan with equal or lesser benefits—no health questions asked.

New York lets you switch anytime with no underwriting, so you’re always guaranteed coverage.

If you’re in another state, you might need to go through underwriting unless you qualify for a special exception. Always good to check before making a switch!

Barbara Cleveland · Answer

The short answer is yes you can as there is not specific enrollment period like for Advantage Plans. 
However, depending on your situation you may be subject to underwriting (Health questions, medical records etc.)
