More than 3 million Medicare Advantage enrollees will need new plans for 2027 — the third straight year of turmoil. If you travel, the plan you pick this fall decides what your medical coverage looks like on the road. Here's the traveler's checklist, with the December 7 deadline front and center.

What's Happening: The 2027 Cancellation Wave

Medicare Advantage — the private-insurer alternative to Original Medicare, now covering more than half of all Medicare beneficiaries — is going through its third straight year of plan cancellations and benefit cuts. The driver, per today's reporting: medical costs are outpacing the federal reimbursements insurers receive, squeezing plan margins until carriers exit markets or trim offerings.

The scale is striking. A JAMA study cited in today's coverage found that forced disenrollment — enrollees pushed out because their plan was discontinued — jumped from roughly 1% per year (2018–2024) to about 10% in 2026, or 2.9 million members. Now the 2027 cycle is shaping up the same way, with CNN reporting that more than 3 million enrollees will need to find new plans.

There is also a political overlay worth knowing about: the midterms are weeks away, and the administration's $90 Medicare premium payment to roughly 20 million seniors notably excludes Medicare Advantage enrollees — a detail that may matter to your household budget planning, whatever your politics.

5 Things to Check Before December 7

Whether or not your plan was cancelled, open enrollment is your annual chance to make sure your coverage fits the way you actually live — including the way you travel. Work through these five checks:

1. Confirm your plan's 2027 status

Read every letter from your insurer dated this fall. If your plan is being discontinued, the notice explains your options and your special enrollment period. Even without a discontinuation notice, plans change their premiums, drug formularies, and provider networks every year — the plan that was perfect in 2026 may not be in 2027. Verify on Medicare.gov's plan finder or call your plan directly.

2. Audit the drug formulary

If you take prescriptions, check that each drug is covered under the 2027 formulary — and at what tier. A plan switch that drops your medication to a higher tier (or off the formulary entirely) can cost you hundreds per month. This is the single most common expensive surprise in plan switches.

3. Check your doctors — and your travel doctors

Confirm your regular doctors accept the new plan. Then think about where you travel: Medicare Advantage plans typically cover only emergency and urgent care outside your plan's service area. If you spend winters in Florida or Arizona, visit grandkids across the country, or take long RV trips, a plan with a narrow local network can leave routine care uncovered for months at a time.

4. Compare travel and out-of-area rules

This is the check most people skip — and the one that matters most for travelers. Ask each plan you're considering: What exactly is covered when I'm outside the service area? Is routine care covered, or only emergencies? What about urgent-care clinics? What are the out-of-network cost-sharing rules? The cheapest monthly premium can become the most expensive plan if it leaves you uncovered on the road. See the comparison table below.

5. Get free, unbiased counseling from SHIP

Every state runs a State Health Insurance Assistance Program (SHIP) — free, federally funded, unbiased Medicare counseling. Find yours at shiphelp.org or call 1-800-MEDICARE. SHIP counselors can walk through your specific drugs, doctors, and travel patterns against 2027 plan options. This is the single best free resource most seniors never use.

Medicare Advantage vs. Medigap: The Traveler's Comparison

Editorial framing: the table below compares the two main paths through the lens that matters to travelers — where you're covered. Premiums and benefits vary enormously by plan and state; treat this as a starting framework, not a recommendation.

What to Do If Your Plan Was Cancelled for 2027

If you received a discontinuation notice, don't panic — you have a clear path, and you're far from alone (roughly a million people are in the same boat just from the UnitedHealthcare and Humana cancellations). Here's the sequence:

1. Read the notice carefully. It names your options, your special enrollment period dates, and whether your insurer is auto-mapping you to a replacement plan. Do not assume the auto-mapped plan is your best option — it's the insurer's default, not a personalized recommendation.
2. Shop during open enrollment (through December 7). Use Medicare.gov's plan finder to compare 2027 plans on premiums, drug formularies, networks, and out-of-area rules. Enrolling during open enrollment guarantees coverage starting January 1, 2027 with no gap.
3. Verify your doctors and drugs under any plan you're considering — call the doctor's office, don't rely solely on online directories.
4. Talk to SHIP. Free, unbiased, and specifically designed for moments like this: shiphelp.org.
5. Consider whether this is your Medigap moment. If you've been thinking about switching to Original Medicare + Medigap for travel flexibility, a plan discontinuation can be the trigger — but check your state's underwriting rules first, because guaranteed-issue rights vary.

The Travel Insurance Piece Nobody Mentions

Here's what the Medicare news cycle won't tell you: neither Medicare Advantage nor Original Medicare covers you well outside the United States. Original Medicare generally covers nothing abroad except narrow border-emergency exceptions. Some Advantage plans and some Medigap policies include limited foreign-travel emergency coverage — but with low lifetime caps.

If you travel internationally at all, a separate travel medical insurance policy is essential regardless of which Medicare path you choose. This is the gap most retirees get wrong: assuming their domestic coverage follows them overseas. It doesn't. Our travel disruption guides cover the logistics side; for the medical side, talk to a travel insurance specialist before your next international trip — and factor that cost into your 2027 planning.

Frequently Asked Questions

Is my Medicare Advantage plan being cancelled for 2027?

More than 3 million Medicare Advantage enrollees will need to find new plans for 2027, according to CNN's October 21, 2026 reporting — the third year of such turmoil. UnitedHealthcare is cancelling plans covering roughly 390,000 members and Humana is cancelling plans covering roughly 600,000 members (about 8% of its Medicare base), together affecting around 1 million people, per the New York Post's same-day reporting. Your insurer must notify you by mail if your plan is discontinued. Check any letters from your insurer dated this fall, and confirm your plan's 2027 status on Medicare.gov or by calling your plan directly.

What is the deadline to switch Medicare plans for 2027?

Medicare open enrollment for 2027 coverage runs through December 7, 2026. If your Medicare Advantage plan is being discontinued, you will also qualify for a special enrollment period, but the December 7 deadline is the safest target — switching during open enrollment guarantees your new coverage starts January 1, 2027 with no gap.

How does switching Medicare plans affect my travel medical coverage?

Medicare Advantage plans typically cover only emergency and urgent care outside your plan's service area, and many have limited or no coverage for routine care while traveling — a key concern for snowbirds and frequent travelers. Original Medicare plus a Medigap supplement generally covers you anywhere in the U.S. that accepts Medicare, with no network restrictions. If you travel often or spend winters in another state, compare each 2027 plan's out-of-area and travel-emergency rules before you enroll — the cheapest premium can become the most expensive plan if it leaves you uncovered on the road.

What is the difference between Medicare Advantage and Medigap for travelers?

Medicare Advantage (Part C) is a bundled plan run by a private insurer with its own provider network, service area, and rules — coverage outside that area is usually limited to emergencies. Medigap (Medicare Supplement Insurance) pairs with Original Medicare and lets you see any doctor or hospital in the U.S. that accepts Medicare, with no referrals or networks. For travelers, snowbirds, and RVers, Medigap's nationwide acceptance is the main advantage; Medicare Advantage's main advantage is lower premiums plus extras like dental and vision. Note: switching from Medicare Advantage to Medigap later can trigger medical underwriting in most states, so the choice you make this fall has long-term consequences.

What should I do if my Medicare Advantage plan was cancelled for 2027?

First, read your insurer's discontinuation notice carefully — it explains your options and deadlines. Second, use Medicare's open enrollment (through December 7) to pick a 2027 plan: compare premiums, drug formularies, provider networks, and — if you travel — out-of-area coverage rules on Medicare.gov's plan finder. Third, check whether your current doctors accept the new plan. Fourth, consider free, unbiased counseling from your State Health Insurance Assistance Program (SHIP) — find yours at shiphelp.org. Finally, if you take prescriptions, verify each drug is covered under the new plan's formulary before you enroll.

Does Medicare cover me when I travel outside the U.S.?

Generally no. Original Medicare does not cover health care outside the United States except in very limited situations (such as emergencies near the U.S. border). Some Medicare Advantage plans and some Medigap policies (Plans C, D, F, G, M, and N) include limited foreign-travel emergency coverage — typically a $50,000 lifetime maximum with a $250 annual deductible. If you travel internationally, this is why a separate travel medical insurance policy is essential regardless of which Medicare option you choose.
