Medicare Advantage Shake-Up: 7 Steps to Protect Your Coverage When Plans Disappear

If you're enrolled in Medicare Advantage, you might have heard some unsettling news lately. Major insurance companies are pulling back from the Medicare Advantage market in a big way, leaving more than a million Americans scrambling to find new coverage. This isn't just a minor adjustment: it's a full-scale shake-up that could affect your healthcare access and costs.
Here's what's happening: Insurance giants like Humana and UnitedHealthcare are cutting hundreds of thousands of members from their plans. Humana alone may drop coverage for 500,000 people, while UnitedHealthcare could impact another 600,000 members. The reason? Rising medical costs, policy changes, and the simple fact that many plans just aren't profitable anymore.
If you're feeling overwhelmed, you're not alone. But don't panic. We've put together seven essential steps you can take right now to protect your coverage and ensure you don't get caught without the healthcare protection you need.
Step 1: Check Your Annual Notice of Changes (ANOC) Immediately
Your ANOC is your lifeline in this situation. This document, which you should receive by September 30th, tells you exactly what's changing with your plan for the next year: including whether your plan is being discontinued altogether.
Don't just glance at it and toss it aside. Read every page carefully. Look for:
Changes in monthly premiums
Modifications to copayments and deductibles
Updates to your prescription drug coverage
Changes to your provider network
Most importantly, any notice that your plan is ending

If your plan is being discontinued, the ANOC will explain your options and deadlines. Time is critical here, so treat this document like the important legal notice it is.
Step 2: Verify Your Doctors Are Still In-Network
Even if your plan continues, your favorite doctors might not be part of it anymore. Medicare Advantage plans can drop providers from their networks at any time throughout the year, and they're only required to give you 30 days' notice.
Here's how to check:
Visit your plan's website and search their provider directory
Call your insurance company directly to confirm
Contact your doctors' offices to verify they're still accepting your plan
If your primary care doctor or specialists are no longer covered, you'll face a tough choice: find new doctors or pay out-of-pocket to keep seeing your current ones. Neither option is ideal, but knowing early gives you time to plan.
Step 3: Understand Your Enrollment Timeline
The Medicare Annual Enrollment Period runs from October 15 through December 7. This is your window to make changes for the following year. If your plan is ending, you must act during this period: there are no extensions or second chances.
Mark these dates on your calendar:
October 15: Enrollment begins
December 7: Final deadline to enroll
January 1: New coverage begins
Don't wait until the last minute. Popular replacement plans can fill up quickly, and you want to avoid any gaps in coverage that could leave you without protection.
Step 4: Research All Your Coverage Options
When your Medicare Advantage plan disappears, you have several paths forward. Each has different pros and cons:
Option 1: Choose Another Medicare Advantage Plan Look for plans in your area that cover your doctors and medications. Compare premiums, deductibles, and out-of-pocket maximums carefully.
Option 2: Switch to Original Medicare Plus Medigap This combination often provides more flexibility in choosing doctors but typically costs more than Medicare Advantage.
Option 3: Original Medicare with Standalone Part D You'll need separate prescription drug coverage, but you'll have broader provider access.

Consider your specific needs: Do you have chronic conditions requiring specialist care? Are you taking expensive medications? Do you travel frequently? These factors should guide your decision.
Step 5: Compare Costs Beyond Just Monthly Premiums
While it's tempting to focus on monthly premiums, that's only part of your total healthcare costs. Many Medicare Advantage plans have low or zero premiums but higher out-of-pocket costs when you actually need care.
Calculate your total annual costs by considering:
Monthly premiums
Annual deductibles
Copayments for doctor visits
Prescription drug costs
Out-of-pocket maximums
Coinsurance for hospital stays
A plan with a higher premium might actually cost you less overall if it has lower deductibles and copayments for the services you use most.
Step 6: Get Professional Help Navigating Your Options
This stuff is complicated: there's no shame in admitting that. The Medicare system has dozens of moving parts, and with plans disappearing left and right, even experienced Medicare users can feel lost.
Consider working with:
A licensed insurance agent who specializes in Medicare
Your State Health Insurance Assistance Program (SHIP)
Medicare's official plan finder tool at Medicare.gov

Step 7: Have a Backup Plan Ready
Given that more changes are expected in 2026, don't treat this as a one-time problem to solve. The Medicare Advantage market is in flux, and what works for 2025 might not be available in 2026.
Create your backup strategy:
Keep records of your preferred doctors and their contact information
Document your prescription medications and dosages
Research multiple plan options, not just your top choice
Set calendar reminders for next year's enrollment period
This proactive approach will save you stress and ensure you're never caught off-guard again.
The Bigger Picture: Why This Is Happening
Understanding why plans are disappearing can help you make smarter choices going forward. The main drivers include:
Rising medical costs that are outpacing what Medicare pays insurers, policy changes that reduced government payments to Medicare Advantage plans, and the ongoing effects of the Inflation Reduction Act on prescription drug costs.
PPO plans are getting hit especially hard because they cost more to operate while allowing members to see out-of-network doctors. Insurers are focusing on smaller, more sustainable plan portfolios rather than trying to be everything to everyone.
Don't Wait: Act Now
The Medicare Advantage shake-up isn't slowing down anytime soon. More changes are coming in 2026, and the companies that remain in the market are going to be pickier about who they cover and where they operate.
If you're affected by plan cancellations, start working through these seven steps today. The earlier you begin, the more options you'll have and the better prepared you'll be for whatever comes next.
Remember, you're not alone in this process. Whether you work with us at Trek Insurance Solutions or another trusted advisor, getting professional guidance can make the difference between finding great coverage and settling for whatever's left when the enrollment deadline approaches.
The Medicare landscape is changing rapidly, but with the right preparation and guidance, you can navigate these changes successfully and maintain the healthcare coverage you need.
