Medicare Open Enrollment 2026: What Virginia Retirees Should Know

The Key Dates for This Year

The Medicare Open Enrollment Period, also called the Annual Enrollment Period, runs October 15 through December 7, 2026. Any changes you make during that window take effect January 1, 2027.

During this period you can join, switch, or drop a Medicare Advantage plan (Part C), a stand-alone Part D prescription drug plan, or return to Original Medicare. You can also compare premiums, deductibles, copays, and drug coverage for 2027, and switch plans if your current one is changing its costs or network.

Why Everyone With Medicare Should Review Plans Each Fall

Plan details change every year. A Medicare Advantage plan that served you well this year may raise its premium, narrow its doctor or hospital network, or change its drug formulary for 2027. The plan you picked once is never a set-and-forget choice, which is why the fall open enrollment window exists. Plan materials arrive by mail each fall, and the Medicare Plan Finder on the official Medicare website lets you compare 2027 plans side by side by drug costs, monthly premiums, and out-of-pocket limits.

Original Medicare Travels With You

If you stay on Original Medicare, Parts A and B, your coverage works the same in every state. It moves with you automatically when you relocate, with no re-enrollment needed, as long as the doctors, hospitals, and other providers you use accept Medicare. For retirees who frequently split time between two homes or who relocate across state lines, traveling with Original Medicare is simple and predictable.

Moving Can Change Your Medicare Advantage and Part D Options

Medicare Advantage and Part D plans are different from Original Medicare. They are tied to a specific service area, typically defined by a state, a set of counties, or ZIP codes. Move to a new address, even to a new county within Virginia, and you can end up outside your current plan's service area.

That is not a problem you have to wait to solve. A permanent move outside your plan's service area triggers a Special Enrollment Period, which lets you enroll in a new Medicare Advantage or Part D plan, or switch to Original Medicare plus a stand-alone Part D plan, outside the normal fall window. You do not have to wait for the next open enrollment, and you do not face a Part D late-enrollment penalty for using this window.

How the Special Enrollment Period Works for Movers

The Special Enrollment Period for a move begins when you notify your plan of the move, or in the month before the move if you notify them in advance, and it lasts up to two full months after the move. That gives you time to settle in, find new doctors, and choose a plan that works in your new county without rushing.

If your new address is still inside your current plan's service area and the plan is still offered there, no Special Enrollment Period is triggered. In that case you keep your plan and simply update your address with Social Security and with your plan directly.

A Virginia Move Checklist

Whether you are downsizing across town or across the state, these steps keep your coverage intact through the move:

• Update your address with Social Security first, since Medicare plans receive address changes from Social Security
• Call your current Medicare Advantage or Part D plan to confirm whether your new county is in its service area
• Check that your current doctors and pharmacies are in network for any plan you are considering
• Compare 2027 plans available in your new county, including premiums, drug tiers, and out-of-pocket costs
• Know your SEP dates: note when you notified the plan so you use the window before it closes

One More Window: January Through March

Separate from the fall open enrollment, the Medicare Advantage Open Enrollment Period runs January 1 through March 31 each year. During that window, people already in a Medicare Advantage plan can make one change: switch to a different Advantage plan or return to Original Medicare. It does not apply to people on Original Medicare with a stand-alone Part D plan, so the fall window remains the main chance to review your Part D drug coverage.

Plan Around Your Move, Not Around the Calendar

The good news for Virginia retirees is that you rarely have to choose between the right move date and the right coverage. If your downsizing move takes you outside your current plan's service area, the Special Enrollment Period protects you. If your move keeps you in the same service area, the fall open enrollment window is still your annual chance to review your 2027 plan. Either way, the fall months are the natural time to review your health coverage alongside your housing plans.
