Bangor Medicare Deadlines: Oct. 15, Dec. 7, March 31

Bangor, Maine — If you live in the Queen City and you're on Medicare (or about to be), the calendar matters more than almost anything else. Miss a window, and you may be stuck with your current coverage — or no drug coverage at all — until the next one opens.

Bangor is in Penobscot County, where 30 Medicare Advantage plans were offered for 2026 through 6 carriers, according to CMS Landscape data. The 2027 lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder. Either way, the enrollment dates decide when you get to sort it.

Here's a plain-English guide to the deadlines that shape your Medicare year, and where in Bangor to get unbiased help lining them up.

The Annual Enrollment Period: Oct. 15 – Dec. 7

This is the big one. Between October 15 and December 7 each year, anyone with Medicare can:

• Switch from Original Medicare to a Medicare Advantage plan, or vice versa.
• Change from one Medicare Advantage plan to another.
• Join, drop, or switch a Part D drug plan.

Whatever you choose during AEP takes effect January 1, 2027. If December 7 passes and you did nothing, your current plan simply rolls into next year — with whatever changes the plan itself made to premiums, drug lists, or provider networks. That's why the "Annual Notice of Change" letter that arrives each September is worth reading, even if you love your current coverage.

Penobscot County had 30 Medicare Advantage plans available in 2026, and the 2027 lineup is listed in each plan's ANOC and on Medicare.gov's Plan Finder — AEP is when Bangor residents actually get to compare them side by side.

The Medicare Advantage Open Enrollment Period: Jan. 1 – March 31

If you're already in a Medicare Advantage plan on January 1 and it isn't working out, you get a second chance. From January 1 through March 31, you can:

• Switch to a different Medicare Advantage plan (with or without drug coverage).
• Drop your Medicare Advantage plan and go back to Original Medicare, and add a stand-alone Part D plan if you want one.

You only get to use this window once, and it's only for people already enrolled in Medicare Advantage. If you're on Original Medicare on January 1, this period isn't for you.

Note: Maine has 9 stand-alone Part D plans for 2026, sold statewide, per CMS's Part D Landscape files; the 2027 lineup (8 plans statewide) appears on Medicare.gov's Plan Finder. If you're planning a switch back to Original Medicare, confirm your drug plan options there before you make the move.

Your Initial Enrollment Period: the 7 months around age 65

Turning 65 in Bangor? Your Initial Enrollment Period (IEP) starts 3 months before your birthday month, includes your birthday month, and runs 3 months after — 7 months total.

Sign up during those months and your Part B coverage starts smoothly. Delay without other creditable coverage (like an employer plan) and you may face:

• A Part B late enrollment penalty of 10% for every 12 months you were eligible but didn't sign up — added to your premium for as long as you have Part B.
• A Part D late enrollment penalty that grows the longer you go without creditable drug coverage.

These penalties aren't one-time — they follow you.

What if you miss a window?

Missing AEP or your IEP isn't always the end of the road. You may qualify for a Special Enrollment Period (SEP) if you:

• Move out of your plan's service area (a real consideration if you leave Penobscot County).
• Lose employer or union coverage.
• Qualify for Extra Help or Medicaid.
• Live in a nursing facility.

There are others. SEPs generally give you about 2 months to act, so don't wait to call once your situation changes.

How the dates interact

Think of it as layers:

1. Age 65: Your IEP is your first shot. Use it. 2. Every fall (Oct. 15 – Dec. 7): AEP is your yearly do-over for Advantage and Part D. 3. Every winter (Jan. 1 – March 31): MA Open Enrollment is your one-time "oops" window if your new Advantage plan isn't right. 4. Anytime: SEPs cover life changes.

One more set of figures worth knowing: the Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027; the Part D maximum deductible is $615 in 2026 and $700 in 2027; and the optional Medicare Prescription Payment Plan lets you spread drug costs across the calendar year in monthly installments.
