Should You Switch Medicare Advantage Plans for 2027?

Every fall, your mailbox fills up with plan letters, and it's easy to toss them aside. But that one envelope from your Medicare Advantage plan — the Annual Notice of Change — could hold the key to whether you overpay, lose access to a favorite doctor, or run into new coverage headaches in 2027. Here's how to read it, compare your options, and decide whether switching makes sense.

Start With the Annual Notice of Change (ANOC)

Your Medicare Advantage plan is required to send you an Annual Notice of Change before the fall Annual Enrollment Period (AEP) begins. This document spells out exactly what's changing about your plan for 2027 compared to this year. Don't skip it, even if you've been happy with your plan for years — insurers routinely adjust costs, coverage, and provider networks from one year to the next.

6 ANOC Red Flags to Look For

1. Premium changes: Is your monthly premium going up, down, or staying the same?
2. Deductibles and copays: Are your out-of-pocket costs for doctor visits, hospital stays, or prescriptions shifting?
3. Drug formulary changes: Is a medication you take being moved to a higher tier, or dropped from the list altogether?
4. Provider network changes: Is your doctor, specialist, or preferred hospital still in-network for 2027?
5. Prior authorization requirements: Are new services now requiring approval before the plan will pay? This information lives in the plan's Evidence of Coverage and its separately published prior authorization list, not the provider directory, so it's worth checking both if you rely on ongoing treatments or specialty care.
6. Extra benefits: Are dental, vision, hearing, or fitness perks changing in scope or disappearing?

If anything in the ANOC surprises you, that's a signal to dig deeper before AEP ends.

Comparing Your 2027 Options

Once you know what's changing with your current plan, it's time to see what else is available in your area for 2027. Medicare Advantage plans, Medicare Supplement combinations, and Original Medicare with a standalone drug plan can all look very different depending on your health needs and budget.

Questions to Ask Yourself

• Are my current doctors and hospitals in-network for any plan I'm considering?
• Are my prescriptions covered, and at what cost tier?
• What's the plan's out-of-pocket maximum, and how does it compare to what I'm paying now?
• Does the plan require referrals or prior authorization for the care I use most?
• Are the extra benefits I actually use — like dental or transportation — still included?

The Medicare Plan Finder tool at Medicare.gov lets you compare plans side by side using your specific medications and providers. It's the most reliable way to see real numbers for your situation rather than relying on plan advertisements, which tend to highlight the best features and downplay the rest.

When Switching Makes Sense

Not every year calls for a change, but certain situations are strong signals that it's worth shopping around:

• Your doctor or hospital is leaving the plan's network in 2027.
• A medication you depend on is being dropped or moved to a much higher cost tier.
• Your premium, deductible, or copays are rising in a way that doesn't match the value you're getting.
• You've had repeated trouble getting prior authorization approved for care you need.
• Your health has changed, and a plan with different extra benefits (like more comprehensive dental or a lower specialist copay) would serve you better now.

When Staying Put Might Be Fine

If your ANOC shows only minor cost adjustments, your doctors remain in-network, and your medications are still covered at a similar cost, there may be little reason to switch. Changing plans isn't free of risk — a new plan could have its own unexpected gaps, so switching just for a slightly lower premium isn't always worth the trade-off if your current plan is working well.

Don't Forget the Appeals Process — Even After You Switch

Sometimes the reason people want to switch plans is frustration with a denied claim or a prior authorization headache. That's understandable, but it's worth knowing that a denial doesn't have to be the end of the story, whether you stay with your current plan or move to a new one for 2027.

If your Medicare Advantage plan denies coverage, you'll receive a Notice of Denial of Medical Coverage or Payment (also called the Integrated Denial Notice). You generally have 65 calendar days from the date on that notice to file a Level 1 appeal, known as a plan reconsideration — and this deadline applies whether your appeal is standard or expedited, so mark the notice date itself, not when it arrived in your mailbox. If you miss that window, you can ask for a good-cause extension, so don't assume a late filing automatically closes the door.

If your plan upholds its denial, your case is automatically forwarded to the Independent Review Entity (IRE) for Level 2 review — you don't need to file anything separately for that step. Beyond that, further appeal levels involve an Administrative Law Judge hearing, the Medicare Appeals Council, and potentially federal court, each with its own filing deadline based on when you receive the prior decision.

According to a KFF analysis of 2024 data, roughly 80% of appealed Medicare Advantage prior-authorization denials are overturned, though only about 11.5% of denied prior-authorization requests are actually appealed. In other words, appealing is often worth the effort, even though many people don't take that step. If you're facing a denial now or worried about one in the future, don't let it push you into switching plans out of frustration alone — appealing first may resolve the issue without a plan change at all.

Special Situations: Hospital and Facility Discharges

If you're told your coverage is ending in a skilled nursing facility, home health, or CORF setting, you'll receive a Notice of Medicare Non-Coverage. You can request a fast-track appeal with the Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) by noon of the day before the effective date on that notice — by phone or in writing. Even if you miss that specific deadline, you still retain fast-track appeal rights and can appeal after services end.

For an inpatient hospital discharge, the notice is called the Important Message from Medicare, and you must contact the BFCC-QIO by midnight of the day of discharge, before leaving the hospital. If you miss that window, you can still ask your Medicare Advantage plan for an expedited reconsideration. These are two separate paths with two separate clocks, so check which notice you received before assuming a deadline.

Making Your Decision Before AEP Ends

Give yourself enough time to read the ANOC carefully, compare plans using the Medicare Plan Finder, and check that your doctors and medications are covered under any plan you're considering. Rushing a decision in the final days of the enrollment period often leads to overlooked details that surface as costly surprises in January.

If you decide a new plan is the better fit for 2027, you can enroll during the Annual Enrollment Period, and your new coverage will begin the following January. If you decide your current plan still serves you well, you don't need to do anything — your enrollment will continue automatically.

Whatever you decide, confirm all current dates, deadlines, and dollar amounts directly at Medicare.gov or by calling 1-800-MEDICARE before you act, since plan details and rules can change from year to year.
