Key Takeaways
-
A top-rated Medicare Advantage plan doesn’t automatically mean it’s the best fit for your personal healthcare needs and budget.
-
Understanding how CMS ratings, out-of-pocket costs, and provider networks affect your coverage helps you make a better-informed enrollment decision.
What Sets the Best Medicare Advantage Plans Apart
In 2025, the best Medicare Advantage plans are those that offer a strong balance of coverage, flexibility, and cost control. These plans, also known as Medicare Part C, combine Part A (hospital) and Part B (medical) coverage and often include additional benefits such as dental, vision, hearing, and prescription drugs.
The Centers for Medicare & Medicaid Services (CMS) evaluates all Medicare Advantage plans annually. Plans receive a rating between 1 and 5 stars based on performance metrics, member satisfaction, care coordination, and preventive services. A 5-star plan is considered top-tier, but it’s not necessarily the right plan for everyone.
How the CMS Star Rating System Works
CMS ratings are updated each fall and play a significant role in determining a plan’s reputation and quality. Ratings are based on:
-
Chronic condition management
-
Preventive screenings and vaccinations
-
Member satisfaction surveys
-
Call center responsiveness and resolution times
-
Timely access to appointments and services
A high CMS rating is helpful, but it doesn’t tell the whole story. You should always look beyond the stars to ensure the plan matches your unique health profile.
Additional Benefits That Sound Great—But Read the Fine Print
Many Medicare Advantage plans in 2025 come with enticing extras:
-
Vision and dental coverage
-
Fitness programs
-
Over-the-counter drug allowances
-
Transportation services
-
Meal delivery
While these extras sound helpful, always check the limits, eligibility rules, and provider networks. A dental plan that covers only preventive care or restricts you to specific clinics may not be as valuable as it first appears.
Why Network Restrictions Matter More Than You Think
One of the biggest differentiators between plans is their provider network. Most Medicare Advantage plans are either:
-
Health Maintenance Organizations (HMOs): Require you to use in-network providers and get referrals for specialists.
-
Preferred Provider Organizations (PPOs): Let you see out-of-network providers at a higher cost, usually without referrals.
Make sure your primary care physician, specialists, and hospitals are all in-network. If they’re not, you could face higher out-of-pocket costs or be forced to switch providers.
Understanding Out-of-Pocket Costs in 2025
CMS limits the maximum out-of-pocket (MOOP) expenses for Medicare Advantage plans in 2025. For in-network services, the MOOP is $9,350. For combined in- and out-of-network services, the limit can be as high as $14,000.
Keep in mind:
-
These limits don’t include monthly premiums, which vary by plan.
-
Prescription drug costs have a separate cap: $2,000 annually under Part D.
-
Some plans have lower deductibles but higher copays, or vice versa.
The best plan is the one that keeps your total expenses predictable, not just low at the surface level.
Prescription Drug Coverage: What’s Changed in 2025
If you choose a Medicare Advantage plan that includes drug coverage, you’ll be automatically enrolled in its Part D benefit. This year, a significant change is the elimination of the coverage gap, or “donut hole.”
Now, once your out-of-pocket drug costs reach $2,000, your plan covers 100% of the remaining drug costs for the year. While this change provides substantial savings, it’s important to understand which medications are covered and how the plan tiers them.
Medicare Advantage Plans and Prior Authorization Rules
Prior authorization remains a widely used tool in Medicare Advantage plans. It requires your doctor to get plan approval before certain services, tests, or medications can be provided.
Services often requiring prior authorization include:
-
Advanced imaging (like MRIs or CT scans)
-
Home health services
-
Inpatient rehabilitation
-
Durable medical equipment
Too many restrictions can delay care, so you should always review a plan’s prior authorization rules before enrolling.
Special Enrollment Opportunities for 5-Star Plans
If a Medicare Advantage plan receives a 5-star rating, CMS allows a one-time Special Enrollment Period between December 8 and November 30 of the following year. This lets you switch into a 5-star plan even outside of the annual Open Enrollment window (October 15 to December 7).
But again, don’t be swayed by ratings alone. Check coverage, costs, networks, and drug formularies.
Enrollment Timelines to Keep in Mind
Knowing when you can enroll or change plans is just as important as choosing the right plan. Here’s a breakdown for 2025:
-
Initial Enrollment Period (IEP): Begins 3 months before your 65th birthday month and ends 3 months after.
-
Annual Enrollment Period (AEP): Runs from October 15 to December 7 each year.
-
Medicare Advantage Open Enrollment Period (MA OEP): January 1 to March 31. Allows you to switch to a different Medicare Advantage plan or return to Original Medicare.
-
Special Enrollment Periods (SEPs): Triggered by life events like moving, losing employer coverage, or enrolling in a 5-star plan.
Missing a deadline could lock you into a plan that doesn’t suit your needs for the entire year.
Coverage Gaps You Might Not Expect
Even top-rated plans can leave coverage gaps, especially for:
-
Skilled nursing care beyond 20 days
-
Long-term custodial care
-
Foreign travel emergencies
You may need to consider separate coverage or savings to protect yourself from unexpected expenses in these areas.
Plan Stability and Yearly Changes
Every fall, you’ll receive an Annual Notice of Change (ANOC) from your plan. It outlines changes in:
-
Premiums
-
Deductibles and copayments
-
Covered services and drugs
-
Provider networks
Always review this document carefully, even if you’re happy with your plan today. What worked in 2024 may not be as effective in 2025.
Choosing a Plan Based on Your Health Profile
Not every Medicare Advantage plan suits every person. Evaluate your options based on:
-
Frequency of doctor visits
-
Chronic conditions
-
Preferred providers
-
Prescription drug needs
-
Desire for added benefits (like fitness or dental)
A plan that works well for someone else may not serve you in the same way.
What to Do Before You Enroll
Before committing to any plan:
-
List your providers and confirm they are in-network.
-
Make a list of your prescriptions and compare formularies.
-
Estimate your total costs using the plan’s summary of benefits.
-
Check for hidden rules like prior authorization or step therapy.
These steps help you avoid surprises and keep your coverage predictable.
Smart Enrollment Starts with the Right Information
Making the right choice for your Medicare Advantage plan in 2025 means taking a close look at your needs, understanding CMS ratings, and comparing real coverage—not just headlines or promises. Use the available enrollment periods wisely, and don’t skip the fine print.
