If you’re one of thousands of Maine residents relying on Medicare Advantage, your 2026 coverage just got complicated. Several insurers are pulling out of Maine’s MA market or drastically cutting available plans, leaving beneficiaries scrambling to find replacement coverage before the December 7, 2025 deadline.
Miss that date? Your new plan won’t start until February or March 2026—meaning potential gaps in doctor visits, prescriptions, and specialist care right when winter health challenges hit hardest.
The Maine Bureau of Insurance issued an urgent advisory in October 2025, warning affected members to act fast. Here’s what you need to know to protect your healthcare access.
Why Are Medicare Advantage Plans Leaving Maine?
The state insurance bureau confirmed multiple MA insurers are reducing their Maine footprint for 2026, though they didn’t name specific companies publicly. This isn’t unique to Maine—nationwide, insurers have been recalibrating their Medicare Advantage offerings due to:
- Reimbursement pressures from federal rate changes that squeezed profit margins in rural and less densely populated states like Maine, where healthcare delivery costs run higher than urban markets.
- Provider network instability. Maintaining contracts with Maine’s scattered rural hospitals and clinics costs more than insurers projected.
- Regulatory compliance costs that increased after recent CMS quality reporting changes in 2024-2025.
The result? Your current plan might disappear January 1, 2026. And if you don’t pick a replacement by December 7, you’re facing delayed coverage at the worst possible time.
Critical Deadlines: When You Must Act
October 15 – December 7, 2025: This is your Annual Open Enrollment window. Choose a new plan during these 54 days, and coverage starts January 1, 2026—no gaps.
December 31, 2025: Your discontinued plan expires. After this date, you’re uninsured unless you selected replacement coverage.
90 days from plan exit notice: You technically have three months to switch plans after receiving your insurer’s termination letter. Sounds generous, right?
Not quite.
Here’s the catch: If you wait until January 2026 to enroll, your new plan doesn’t activate until February 1. Pick a plan in February? Coverage starts March 1. That’s 1-2 months without insurance during flu season, when Maine’s weather keeps people indoors spreading illness.
| Enrollment Month | Coverage Start Date | Gap Period |
|---|---|---|
| Oct 15 – Dec 7, 2025 | Jan 1, 2026 | No gap |
| January 2026 | Feb 1, 2026 | 1 month gap |
| February 2026 | Mar 1, 2026 | 2 month gap |
The lesson? Don’t procrastinate. Enroll by December 7.
What Happens to Your Doctors and Prescriptions?
This is where plan changes hurt most. Not all Medicare Advantage plans contract with the same providers or cover the same drugs.
Your current cardiologist might not accept your new plan. That rheumatologist you’ve seen for years? Could be out-of-network now. The pharmacy two blocks away? Might not be in the new plan’s preferred network, costing you $50-$100 more per prescription.
The Maine Bureau of Insurance specifically flagged this risk in their advisory, urging consumers to verify three things before selecting a replacement plan:
- Does your primary care doctor accept the new plan? Call their office—don’t assume. Provider directories online are notoriously outdated.
- Are your specialists in-network? Oncologists, cardiologists, orthopedic surgeons—these relationships matter. Switching mid-treatment creates continuity-of-care problems.
- Does the formulary cover your medications at the same tier? A drug that cost you $10/month on your old plan might jump to $75/month if the new insurer classifies it as non-preferred.
Use Medicare’s Plan Finder tool to check these details. Enter your doctors and prescriptions to see which plans cover them—and at what cost.
How to Choose Your New Medicare Advantage Plan (Without Regrets)
Picking a replacement plan in 30 days feels overwhelming. Here’s a streamlined process:
Step 1: List Your Non-Negotiables
Write down:
- Your top 3 doctors (primary care, specialists)
- Your current prescriptions (names and dosages)
- Your preferred pharmacy
- Any planned procedures in 2026 (joint replacement, cataract surgery, etc.)
Step 2: Compare 3-5 Plans Using Medicare.gov
Go to Medicare.gov and enter your zip code. The tool shows:
- Monthly premiums
- Out-of-pocket maximums
- Drug coverage costs
- Star ratings (quality scores from CMS)
Focus on plans with 4-5 star ratings. Lower-rated plans often have claims processing delays and customer service problems.
Step 3: Call Plans Directly
Don’t rely solely on online info. Call 2-3 finalist plans and ask:
- “Does Dr. [Name] at [Practice] accept this plan?” (Get the rep’s name and confirmation number.)
- “What’s my out-of-pocket cost for [Drug Name] at [Pharmacy]?”
- “What’s the prior authorization process for [procedure]?” (Some plans require weeks of approvals.)
Step 4: Enroll by Phone
Call 1-800-MEDICARE (1-800-633-4227). Reps walk you through enrollment and confirm effective dates. Get a confirmation number and save it.
Maine-Specific Challenges: Rural Access Gets Harder
Maine’s geography makes MA plan exits especially painful. The state has one of the oldest median populations in the U.S. and vast rural areas where hospital consolidation already limits choices.
If you live in:
- Northern Maine (Aroostook County): Fewer plans serve this area. Expect 1-2 options max, possibly with higher premiums due to low enrollment density.
- Midcoast region: Better options, but specialist access (cardiology, oncology) often requires travel to Portland or Bangor. Check if plans cover out-of-area care.
- Southern Maine: Most plan choices, but networks vary wildly. MaineHealth vs. Northern Light Health affiliations determine which hospitals you can use.

Can You Switch Back to Original Medicare Instead?
Yes, but there’s a catch.
During Open Enrollment, you can drop Medicare Advantage and return to Original Medicare (Parts A & B). You’ll need to add:
- Part D prescription drug coverage (separate plan, roughly $30-$80/month)
- Medigap supplement policy (fills gaps in Original Medicare, costs $150-$350/month in Maine)
Total monthly cost: $180-$430 vs. many MA plans at $0-$100/month.
The trade-off? Original Medicare + Medigap gives you nationwide provider access—no networks, no referrals, no prior authorizations. You see any doctor accepting Medicare.
Best for:
- Snowbirds splitting time between Maine and Florida
- People with complex conditions seeing multiple specialists
- Those who travel frequently and need care flexibility
Downside: Medigap plans in Maine can deny coverage or charge higher premiums if you’re switching from MA after your initial enrollment period. Some insurers require medical underwriting (health questions).
What If You Miss the December 7 Deadline?
You have backup options, but they’re messier:
Medicare Advantage Open Enrollment Period (Jan 1 – Mar 31, 2026): You can switch MA plans once during this window. But remember—coverage starts the month after enrollment, creating gaps.
Special Enrollment Periods (SEPs): Qualify if you:
- Move to a new address
- Lose employer coverage
- Qualify for Medicaid or Extra Help (low-income subsidy)
- Enter a nursing home
SEPs let you enroll anytime, with coverage starting the first of the following month.
Emergency Medicaid: If you have a health crisis during a coverage gap, Maine’s Medicaid program may cover emergency services retroactively. But this isn’t guaranteed—don’t count on it.
Frequently Asked Questions
Which Medicare Advantage plans are leaving Maine in 2026?
The Maine Bureau of Insurance didn’t publicly name specific insurers exiting the market, but confirmed multiple MA plans are discontinuing coverage or reducing service areas statewide. Check your mailbox—affected members received termination notices by late October 2025. You can also call 1-800-MEDICARE and provide your current plan details to confirm if yours is discontinued.
Can I keep my current Medicare Advantage plan through the end of 2025?
Yes. If your plan is discontinued, coverage continues through December 31, 2025. You’ll have full access to doctors, prescriptions, and benefits until year-end. This gives you time to select a replacement without immediate disruption—but you must enroll in a new plan by December 7 to avoid coverage gaps starting January 1, 2026.
What happens if I don’t pick a new plan by December 7?
You’ll face coverage delays. Enroll in January 2026, and your new plan starts February 1. Wait until February to enroll? Coverage begins March 1. During those gap months, you’re responsible for 100% of medical costs—doctor visits, prescriptions, hospital stays. In Maine’s winter, that’s high-risk timing for flu, pneumonia, and weather-related injuries.
How do I find out if my doctor accepts the new Medicare Advantage plan?
Call your doctor’s office directly—don’t trust online directories alone. Ask: “Do you accept [Plan Name] for 2026?” Get the staff member’s name and confirmation date. Then call the insurance plan at the number on their website and verify the doctor is in-network. Cross-checking prevents surprises when you show up for appointments in January.
Should I switch to Original Medicare instead of choosing a new MA plan?
It depends on your health needs and budget. Original Medicare offers nationwide access to any provider accepting Medicare—no networks, no referrals. But you’ll need to buy separate Part D drug coverage (around $30-$80/month) and a Medigap supplement policy ($150-$350/month in Maine). Total cost runs higher than most MA plans, but you gain flexibility. Best for frequent travelers, snowbirds, or people with complex conditions seeing multiple specialists. However, Medigap insurers in Maine can deny coverage or charge higher rates if you’re switching from MA outside your initial enrollment period.
