The Medigap 6-Month Window: The One Enrollment Period That Never Comes Back

There are six months when a Medicare Supplement company cannot use your health to decide whether to sell you a policy or what to charge you.

Miss that window, and what a Supplement costs you — or whether you can get one at all — can change dramatically.

When the clock runs

It starts the first month you have Part B and you are 65 or older. It lasts six months.

If you worked past 65 on an employer plan, your six months has not started yet. It starts the month you take Part B, not the month you turn 65.

What the window gives you

Inside those six months, an insurance company has to sell you any Supplement policy you are eligible for that they offer in your state.

They cannot deny you because of your health. They cannot charge you more because you have been sick.

There is one catch worth knowing: in some cases they can make you wait up to six months before the Supplement covers costs related to a pre-existing condition. But they still cannot deny you the policy over that condition.

What happens outside it

In most states, medical underwriting comes back. They may ask health questions, charge you more, or turn you down.

Why this one is different from every other Medicare deadline

Annual Enrollment comes back every October. Your federal Medigap Open Enrollment Period does not.

It is a one-time, six-month window.

The trap that catches people

Somebody takes a Medicare Advantage plan at 65 because the premium is low. That is a completely reasonable decision and a lot of people make it for good reasons.

Years later their health changes, or their doctor leaves the network, and they decide they want a Supplement instead.

Now they are outside the window. The company may look at their health. The answer can be a much higher price — or no coverage at all.

Being fair about it

I am not telling you a Supplement is the right answer.

A Supplement comes with a monthly premium every single month, healthy or not. For a lot of people that premium is exactly why they chose Advantage in the first place. That is a real budget decision and it is yours to make.

But make it knowing which door may get harder to open later. Medicare Advantage gives you enrollment opportunities every year. Getting a Supplement later may require you to pass medical underwriting.

It is not necessarily your only shot

Some states give additional protections, and certain situations create guaranteed-issue rights later — when a plan leaves Medicare, for example, or stops serving your area.

So this is not the only door that will ever open. It is just the cleanest one you will get under federal rules.

The timing that matters

If you are coming up on your Part B start date, that is the moment to look at both paths seriously — not after.
