Can I be turned down for a Medicare Supplement plan because of a pre-existing condition?

Answered by 5 licensed agents

Yes, in some situations you can — but not when you are in your protected Medicare Supplement enrollment period.

When you are 65 or older and first enroll in Medicare Part B, you get a 6-month Medicare Supplement Open Enrollment Period. During that time, an insurance company cannot turn you down, charge you more because of your health, or use medical underwriting to deny your application.

After that 6-month period ends, the rules can change. In many states, an insurance company may ask health questions and can deny your application if you do not meet its underwriting requirements.

There are also federal guaranteed-issue rights that protect you in certain situations, such as losing specific coverage or leaving Medicare Advantage under certain circumstances. When one of those rights applies, an insurance company cannot use your health to deny the Medigap coverage you are entitled to buy.

Your state may also have its own specific Medigap enrollment protections beyond the federal rules. Those protections are different from state to state, so the rule where you live needs to be checked before assuming medical underwriting will apply.

That is why your first Medicare Supplement enrollment opportunity is so important. It may be the easiest time you will ever have to get the coverage you want without your health history standing in the way.

Yes, in many situations you can be turned down for a Medicare Supplement (Medigap) plan because of a pre-existing condition. During your six-month Medigap Open Enrollment Period, however, insurance companies generally cannot use medical underwriting to deny you coverage or charge you more because of your health. After that period, insurers in many states may review your medical history and can decline your application unless you have a guaranteed-issue right or other state protection. Because underwriting rules vary by company and state, it's important to consult with a qualified Medicare agent to check your eligibility before changing or dropping existing coverage.

Sometimes yes, but not in every situation.

Your strongest federal protection is your six-month Medigap Open Enrollment Period. It begins the first month you are age 65 or older and enrolled in Medicare Part B.

During that protected period, a Medicare Supplement insurance company cannot deny you a Medigap policy because of your health or use medical underwriting to charge you more because of a pre-existing condition.

After that protected period ends, the rules can change significantly. In many situations, an insurance company may use medical underwriting and may decline an application based on health history.

There are important exceptions.

Certain circumstances create federal guaranteed-issue rights, and some states provide additional Medigap protections beyond the federal rules.

This is also why leaving Medicare Advantage for Original Medicare requires careful planning. Being allowed to leave Medicare Advantage does not automatically mean you have a guaranteed right to purchase any Medicare Supplement plan you want.

Before canceling existing coverage, determine whether you have a Medigap open-enrollment right, a guaranteed-issue right, a state-specific protection, or whether medical underwriting will apply.

Plan the destination before giving up the coverage you already have.

When you turn 65 (or if you're older due to retirement) and enroll in Medicare Part B, you enter a period that will allow you guaranteed acceptance into a Medicare Supplement plan. This is good news if you know you have a pre-existing condition because you will not be turned down. It's a specific window of time that comes with that first enrollment into Part B. Outside of that window of time, the only other way to bypass medically qualifying for a supplement plan is by experiencing an event where you lose your health coverage at no fault of your own, or if you are in a 12 month trial period to see if you like Part C. If none of that applies, your pre-existing condition may be a determining issue.

Yes, unfortunately.

The only time that you are able to get on a supplement plan with a pre-existing condition is right when you turn 65 or start Medicare part B, this is known as “Guaranteed Issue”. GI is a period of thins in which you can apply for a supplement plan and you DO NOT have to go through any underwriting questions.

When you first become eligible for part B there’s a little more pressure when weighing the option of Medicare Advantage Vs. Medicare Supplement
