Key Takeaways
-
Medicare Advantage plans can appear similar year after year, but coverage rules and cost-sharing details often change significantly. It’s essential to check beyond the name and branding.
-
A plan that worked well in the past may no longer be the right fit. In 2025, shifting benefits, networks, and out-of-pocket structures mean you must compare carefully during each enrollment period.
Why the Name Might Stay the Same, But the Plan Doesn’t
You might recognize the name of your Medicare Advantage plan from last year or even several years back. But familiarity can be misleading. While the plan’s branding may not have changed, its benefits, provider networks, and cost-sharing requirements often do.
Each year, Medicare Advantage plans submit updates to the Centers for Medicare & Medicaid Services (CMS). These changes take effect on January 1. So even if your plan’s name and structure seem identical, it may include important modifications that could affect your healthcare experience.
Annual Changes You Should Expect
Every fall, Medicare Advantage plans issue an Annual Notice of Change (ANOC). This document outlines updates that go into effect for the upcoming calendar year. For 2025, many changes include:
-
Adjusted copayments for specialist or urgent care visits
-
Altered prescription drug formularies
-
New referral requirements for specific services
-
Updated provider network participation
-
Revisions to supplemental benefits like dental or vision
Missing or ignoring the ANOC can lead to unexpected costs or losing access to a provider you rely on.
What Medicare Advantage Is (and Isn’t)
Medicare Advantage (Part C) combines the benefits of Original Medicare (Part A and Part B) with extra features—sometimes including drug coverage, dental, hearing, or transportation services. But the way these benefits are administered varies widely from plan to plan.
Unlike Original Medicare, which is uniform nationwide, Medicare Advantage plans are offered by private companies approved by Medicare and vary by ZIP code. In 2025, your access to certain providers or hospitals may depend entirely on your plan’s network, even if the plan’s name is the same as last year.
Common Rule Differences in 2025 Plans
The details buried in plan documents can lead to big surprises if you’re not careful. Here’s what might differ in your 2025 Medicare Advantage plan:
1. Provider Network Participation
Doctors or specialists you saw last year may no longer be in-network this year. Networks are updated annually. If your preferred provider is no longer included, out-of-network costs could rise sharply or the service may not be covered at all.
2. Prior Authorization Requirements
Many Medicare Advantage plans require prior authorization for services like MRIs, home health care, or even outpatient surgeries. In 2025, some plans have expanded the list of services that need pre-approval.
3. Out-of-Pocket Maximum Adjustments
Each Medicare Advantage plan must include a maximum limit on out-of-pocket expenses for in-network services. In 2025, the federal limit is $9,350 for in-network and $14,000 for combined in- and out-of-network. But each plan can set a lower threshold—and many have. These amounts may differ significantly from last year’s figures.
4. Drug Formulary and Tier Changes
Just because a medication was covered in 2024 doesn’t guarantee it still is. Plans often change drug tiers or drop medications altogether from their formulary. You may face new requirements like step therapy or quantity limits.
5. Changes in Supplemental Benefits
Medicare Advantage plans often market added benefits like dental cleanings, vision exams, gym memberships, and hearing aids. In 2025, some of these benefits have been scaled back or modified. For instance, the share of plans offering transportation benefits dropped from 36% in 2024 to 30% in 2025.
Don’t Assume—Compare Carefully Every Year
If you’re enrolled in a Medicare Advantage plan, comparing your current plan against others during the Open Enrollment Period (October 15 to December 7) is critical. Sticking with the same plan without a second look could cost you:
-
Higher copayments and coinsurance than expected
-
Loss of access to preferred doctors or hospitals
-
Reduced or removed supplemental benefits
The Annual Notice of Change: Your First Clue
The ANOC, mailed each September, gives you the earliest view of how your plan will change in the coming year. Even minor shifts in your healthcare needs or usage can make a big difference when combined with a plan’s new structure.
Regional Differences in Medicare Advantage Plans
In 2025, there are over 3,900 Medicare Advantage plans available nationwide, but most people only have access to a small subset based on where they live. What’s available in your area may differ dramatically from what someone else sees just one county over.
This means a plan with a familiar name could have:
-
A completely different provider network
-
Different cost-sharing rules
-
Distinct rules for referrals or authorizations
If you move—even within the same state—you’ll need to verify whether your current plan is still available and what changes might apply in your new location.
The Influence of Star Ratings
Every year, CMS assigns star ratings to Medicare Advantage plans based on performance, member satisfaction, preventive services, and customer service. These range from 1 to 5 stars.
However, even a plan that received a high rating in 2024 may perform differently in 2025. Ratings can change due to member complaints, decreased quality of care, or reporting issues. In some cases, plans lose their contract altogether.
Before you re-enroll based on a plan’s past reputation, check its current star rating.
When to Rethink Your Plan
Here are a few situations where reevaluating your Medicare Advantage plan is especially important in 2025:
-
You have new prescriptions or health conditions
-
Your doctor has left the plan’s network
-
You received a lower-than-expected reimbursement for a past service
-
Your plan dropped a supplemental benefit you relied on
-
You’re moving to a new ZIP code
Enrollment Periods That Matter
To make changes or switch plans, you need to act during specific windows:
Medicare Open Enrollment (October 15–December 7)
This is the main opportunity to switch from Original Medicare to Medicare Advantage, change Advantage plans, or return to Original Medicare.
Medicare Advantage Open Enrollment (January 1–March 31)
If you’re already enrolled in a Medicare Advantage plan, this window allows you to make a one-time switch to another Medicare Advantage plan or return to Original Medicare.
Outside these dates, changes are only allowed for special circumstances, such as moving or losing coverage.
The Danger of Letting Auto-Enrollment Do the Work
Auto-enrollment keeps you in the same Medicare Advantage plan each year unless you make a change. While convenient, it assumes the plan still fits your medical and financial needs.
But in 2025, with frequent adjustments to networks, drug coverage, and costs, relying on auto-enrollment could mean staying in a plan that no longer serves you well.
It’s safer to review your plan in full—even if you ultimately choose to stay.
Your Medicare Plan Should Evolve With You
You shouldn’t feel locked into a plan just because it looks familiar. Medicare Advantage plans in 2025 are constantly adapting to economic, regulatory, and healthcare delivery shifts.
Evaluate your needs every year:
-
Have your medications changed?
-
Did your preferred doctor exit the network?
-
Is your out-of-pocket spending increasing?
Matching your healthcare coverage to your life as it is now—not as it was—ensures your plan supports you where you are.
Stay Informed and Choose With Confidence
Understanding that familiar names don’t mean familiar rules is one of the smartest decisions you can make about your Medicare Advantage plan in 2025. You owe it to yourself to go beyond surface appearances and examine what truly fits your needs.
