Medigap vs. Advantage in Grand Forks: 2027 Dates

GRAND FORKS, N.D. — If you live in Grand Forks and you're weighing Original Medicare with a Medigap policy against a Medicare Advantage plan, the choice isn't just about coverage style. It's also about the calendar. The two paths have different enrollment windows, and missing one can lock you into a decision — or lock you out of a policy — for longer than you'd expect.

Here's what Grand Forks residents need to know about the deadlines that shape the 2027 plan year.

Why the two paths have different clocks

Original Medicare (Parts A and B) is the federal program. A Medigap policy is separate — it's private insurance that helps pay the out-of-pocket costs Original Medicare leaves behind, and many people pair it with a stand-alone Part D drug plan.

Medicare Advantage (Part C) is also private, but it replaces the way you get your Part A and Part B benefits and usually bundles in drug coverage.

Because Medigap and Advantage are governed by different rules, their enrollment deadlines don't line up. That's the part that trips people up.

The Medicare Advantage and Part D windows

For anything involving Medicare Advantage or Part D drug coverage, two windows matter most:

• Annual Enrollment Period (AEP): Oct. 15 – Dec. 7, 2026. This is when you can join, switch, or drop a Medicare Advantage plan, or change your Part D plan. Choices made here take effect Jan. 1, 2027.
• Medicare Advantage Open Enrollment Period (MA-OEP): Jan. 1 – March 31. If you're already in an Advantage plan on Jan. 1, you get one chance in this window to switch to a different Advantage plan or drop back to Original Medicare (and pick up a Part D plan).

Miss both, and outside of a Special Enrollment Period tied to a life event, you'll generally wait until the next AEP to make a change.

The Medigap window is the one people overlook

Medigap doesn't use AEP. It has its own timing, and this is where a Grand Forks reader can quietly lose options.

Your Medigap Open Enrollment Period is a one-time, six-month window that starts the month you're 65 or older and enrolled in Part B. During those six months, insurers must sell you any Medigap policy they offer at their standard rate, regardless of your health history. This is called guaranteed issue.

After that window closes, North Dakota allows insurers to use medical underwriting on most Medigap applications. That means they can look at your health, charge more, or turn you down — unless you qualify for a limited guaranteed-issue right (for example, if your Advantage plan leaves the area).

The practical takeaway: if you think you may ever want Medigap, the safest time to get it is during that first six-month window.

How the dates interact

This is where the two systems can bump into each other:

• If you choose Medicare Advantage when you first become eligible and later decide you'd prefer Original Medicare with a Medigap policy, you can switch back to Original Medicare during AEP or MA-OEP — but a Medigap insurer may not have to sell you a policy at that point.
• There's a 12-month trial right: if you joined an Advantage plan when you first became eligible for Medicare, you have up to a year to switch back to Original Medicare with guaranteed-issue Medigap rights.
• If you drop Medigap to try Advantage for the first time, you generally have 12 months to change your mind and get your Medigap policy back under guaranteed issue.

These trial rights are narrow. Read the details on medicare.gov before you rely on them.

A note on 2027 program facts

A few program-level numbers apply no matter which path you pick:

• The Part D maximum deductible is $615 in 2026 ($700 in 2027).
