Can You Change Medicare Supplement Plans in 2027? Rules, Timing and State Rights

During your open enrollment period. In the 6 months starting the month you are 65 or older and enrolled in Part B, companies must sell you any plan they offer, at their best rate, with no health questions.

With a guaranteed issue right. Certain events, like losing other coverage, give you a short window where the company cannot turn you down.

At all other times. In most states the company can ask about your health, charge more, or decline your application. This is called medical underwriting.

Pre-existing conditions: If you have had your current Medicare Supplement plan for at least 6 months, a new plan generally cannot make you wait for coverage of a pre-existing condition. If it has been less than 6 months, the new plan may make you wait for the months you have left.

New York and Connecticut. Companies must sell Medicare Supplement plans to people 65 and older all year, with no health questions.

Massachusetts. Plans are sold under year-round open enrollment with community rating.

Maine and Washington. Both let many current policyholders switch during the year without a health review, with limits on which plans you can move between.

Compare rates first. Get quotes for the same plan letter, or a lower one, from several companies in your ZIP code.

Apply while your old plan is active. Never cancel your current plan before the new one approves you in writing.

Answer health questions honestly. If you are not in a protected window, the company will review your answers and medical records.

Pick a start date. Ask for the new plan to start on the first of a month and keep paying your old plan until then.

Cancel the old plan in writing. Once the new plan is active, contact your old company to end coverage. Canceling is not automatic.

Broker tip: Line up the start date of the new plan with the end of the old one. A single day without coverage can cost you guaranteed rights in some states.

Your premium jumped. Another company may sell the same plan letter for less. Our page on Plan G rate increases explains why rates rise.

You are paying for more than you use. Moving from Plan G to Plan N can lower your premium if you are healthy and rarely see doctors.

You want a company with better service. Same plan letter, same benefits, but claims and customer service can differ.

You can use a birthday rule. In those states you can shop each year with no risk of a health denial.

Keep both plans for one month. You will pay both premiums during that month, but you have a safety net if the new plan is not right.

Cancel the new plan if needed. If you change your mind during the free look, you can return the new plan and keep your old one.

Then drop the old plan. Once you are sure, cancel the old plan in writing so you do not keep paying.

The fall Annual Enrollment Period does not apply to Medicare Supplement plans. You can apply in the fall, but the same health question rules apply as any other time of year.

It is a state law that gives you a yearly window around your birthday to switch to a plan with the same or fewer benefits without health questions. The window length and limits differ by state.

If you have had your current plan for at least 6 months, the new plan generally cannot make you wait for pre-existing condition coverage. With less time, a waiting period may apply for the months you are short.

No. Keep your old plan until the new one approves you and is active. Then cancel the old plan in writing.

➤ How long is the free look period?
