I thought my Medigap plan would be useless if I moved out of state—is that wrong?

Yes, that's a common misconception, often caused by confusing Medigap with Medicare Advantage. Medigap plans are fully portable nationwide. Your policy stays active wherever you move within the United States. The only thing that changes is potentially your premium amount. Medicare Advantage plans, on the other hand, often have network restrictions that may require you to switch plans when moving.

Can my insurance company drop me because I moved?

No. As long as you pay your premiums, your insurance company cannot cancel your policy because you relocated to a different state.

What if my insurance company doesn't operate in my new state?

Your policy remains valid even if your insurer doesn't actively sell new policies in your destination state. They must continue covering you. However, if they stop doing business entirely or become insolvent, you would have guaranteed issue rights to purchase a new policy.

Will my benefits change?

No. Medigap plans are standardized by federal law. A Plan G in one state offers the same benefits as a Plan G in any other state (except Massachusetts, Minnesota, and Wisconsin, which have different standardization systems).

Can I switch to Medicare Advantage instead?

Yes. You can switch from Medigap to Medicare Advantage during the Annual Enrollment Period (October 15 - December 7) or during the Medicare Advantage Open Enrollment Period (January 1 - March 31). However, switching back to Medigap later would require medical underwriting unless you qualify for guaranteed issue rights.

I'm Moving States, Will My Medigap Plan Still Work?

Your Medigap policy remains active nationwide — you can keep your existing plan when you move to another state, and it will continue to cover Medicare cost-sharing wherever you receive care in the U.S. However, your premiums may change to match rates in your new state. Switching to a different plan after moving is harder because you won't have guaranteed issue rights just because you moved. Some states offer special protections that make switching easier.

Understanding Medigap Portability: The Good News

If you're planning to move to a different state and you have a Medigap policy (also called Medicare Supplement Insurance), there's one crucial fact you need to know right away: your Medigap plan is portable. Your existing policy will continue to work no matter where you move within the United States.

Medigap policies are designed to work anywhere in the country that accepts Original Medicare (Parts A and B). Since Original Medicare is accepted by virtually all providers nationwide, your Medigap coverage travels with you.

This portability is one of the key advantages of Medigap over Medicare Advantage plans, which typically have network restrictions and may require you to switch plans if you move outside your plan's service area.

What Happens to Your Premiums When You Move

While your Medigap policy stays active when you relocate, there's an important caveat: your premium can change.

Insurance companies set Medigap premiums based on various factors, including geographic location. Healthcare costs, state regulations, and competitive market conditions all vary from state to state, which means the same Medigap Plan G in California might have a different premium than an identical Plan G in Georgia.

When you notify your insurance company that you've moved to a new state, they will adjust your premium to reflect the rates in your new location. Key points:

The change can go either way. You might pay more in your new state, or you might pay less.
You must notify your insurer. Don't assume your insurance company will automatically know you've moved.
The timing matters. Your premium adjustment typically takes effect the month after you report your new address.
You can't be cancelled. Federal law protects your right to keep your existing Medigap policy regardless of your health status or where you relocate.

The Challenge: Switching Plans After You Move

While you can definitely keep your existing Medigap plan when you move, switching to a different plan in your new state is much harder.

Guaranteed Issue Rights Don't Follow You

When you first become eligible for Medicare (typically at age 65), you have a six-month Medigap Open Enrollment Period during which insurance companies must sell you any Medigap policy they offer, regardless of your health conditions. This is called "guaranteed issue."

However, moving to a new state does not give you a new guaranteed issue right. If you want to switch plans or change insurance companies in your new state, you'll likely need to go through medical underwriting, which means the insurance company can:

Ask about your health history and current conditions
Request medical records
Deny your application if you have certain health issues
Charge you higher premiums based on your health status
Exclude coverage for pre-existing conditions for up to six months

Limited Exceptions

Trial Rights: If you joined a Medicare Advantage plan when you first became eligible and want to switch back to Original Medicare plus Medigap within your first year, you have guaranteed issue rights.
Loss of Coverage: If your current Medigap insurer becomes insolvent or stops operating in your new state, you have guaranteed issue rights to purchase another Medigap policy.
State-Specific Protections: Some states offer additional consumer protections.

State-Specific Protections: Know Before You Go

States with Annual Enrollment Periods

California offers a birthday rule that allows Medigap policyholders to switch to a plan with equal or lesser benefits within 60 days of their birthday each year, without medical underwriting.

Oregon provides a one-time opportunity to switch during the 60 days following your birthday, but only if you've had your current plan for at least six months.

Missouri allows policyholders to change to plans with equal or lesser benefits during specified periods without underwriting.

States with Guaranteed Issue Protections

Connecticut, Maine, Massachusetts, and New York require community rating for Medigap policies, meaning companies cannot use age or health status in pricing. Massachusetts, New York, and Connecticut also have open enrollment periods beyond the initial six-month window.

Practical Steps When Moving States with Medigap

Before You Move

Review your current plan and assess whether it still meets your needs
Research your destination state's special enrollment periods or guaranteed issue protections
Compare premiums — contact your insurance company to estimate your new rate
Consider making plan changes while you still have access to your current state's protections

During Your Move

Notify your Medigap insurer immediately — update your address before or as soon as you move
Update Medicare by calling Social Security at 1-800-772-1213
Keep all documentation regarding your move and premium changes

After You Move

Confirm your coverage has been updated with your new address and premium
Establish new providers in your area who accept Original Medicare
Review your coverage annually during Medicare's Annual Enrollment Period (October 15 – December 7)

The Bottom Line

Moving to a new state with Medigap coverage is relatively straightforward: your policy stays active, your benefits remain the same, and you have continuous nationwide coverage. The main considerations are potential premium changes and the limited ability to switch plans after you move.

The key to a successful transition is planning ahead. Research your destination state's Medigap landscape, understand what your premiums will be, and consider whether you want to make any plan changes while you still have maximum flexibility.
