How Newark Members Can Change Medicare Advantage Plans

Key takeaways

  • The Medicare Advantage Open Enrollment Period runs from January 1 through March 31 each year, giving current Medicare Advantage members a chance to change their coverage.
  • Only people already enrolled in a Medicare Advantage plan as of January 1 can use this window, not people with only Original Medicare or a standalone Part D plan.
  • This period is different from the Annual Enrollment Period, which runs October 15 through December 7 and is open to anyone with Medicare.
  • Checking details like plan networks and drug coverage before switching can help you decide if a change makes sense for how you use care.

Here's what this window is, what you can do during it, and what it won't let you do.

What the Medicare Advantage Open Enrollment Period actually is

The Medicare Advantage Open Enrollment Period — sometimes shortened to MA-OEP — runs every year from January 1 to March 31. It exists for one reason: to give people already enrolled in a Medicare Advantage plan a chance to fix things if their plan isn't working out.

Maybe your doctor isn't in the network after all. Maybe a medication you take is not covered the way you expected. Maybe the plan simply isn't the right fit. This window gives you a do-over.

It is not the same as the Annual Enrollment Period (October 15 – December 7), when anyone with Medicare can make changes. The January-through-March window is narrower in who it helps and what it allows.

Who can use this window

You can use the Medicare Advantage Open Enrollment Period if, as of January 1, you are enrolled in a Medicare Advantage plan (with or without drug coverage).

You cannot use it if you only have Original Medicare (Parts A and B), with or without a standalone Part D drug plan. For those readers, this window is not the time to make changes — the fall Annual Enrollment Period is.

What you can change — and what you can't

During January 1 – March 31, if you're in a Medicare Advantage plan, you can:

What you cannot do during this window:

Why 2027 makes this window worth a second look

A few program-level changes are worth knowing about as you weigh your options for the year ahead:

If your current plan didn't line up with how you actually use care in January, these are the kinds of details worth checking before you switch.

What's available around Newark

Newark is in New Castle County, where Medicare beneficiaries have a range of Medicare Advantage plans and carriers to choose from. Plan availability, networks, drug formularies, and extras vary by plan and by county — which is why the official Medicare Plan Finder at medicare.gov is the right place to compare specifics for your ZIP code.

If you'd rather talk it through with a human, Delaware's State Health Insurance Assistance Program (SHIP), called ELDERinfo, offers free, unbiased counseling. They don't sell plans and they don't earn commissions.

A: Your new coverage begins the first day of the month after the plan receives your enrollment request. Switch in February, coverage typically starts March 1.
