Key Takeaways

• Even the highest-rated Medicare Advantage plans in 2025 involve trade-offs, including network limitations and prior authorization hurdles.

• You must weigh benefits like dental, vision, and cost-sharing against coverage restrictions, annual limits, and out-of-pocket maximums.

Medicare Advantage in 2025: What Makes a Plan the “Best”

As you compare Medicare Advantage plans in 2025, it may seem like there are clear winners based on benefit packages or star ratings. But the reality is more complex. The “best” plan for you depends not only on what’s offered but also on what you actually need, how often you need care, and what kind of restrictions you’re willing to accept in exchange for potential savings or extra benefits.

Medicare Advantage, also known as Medicare Part C, combines your Medicare Part A (hospital insurance) and Part B (medical insurance), and often includes prescription drug coverage. Many plans also offer extra benefits not covered by Original Medicare.

So why is this not a perfect solution? Because each plan is a package of trade-offs. One plan might offer robust dental and vision, but restrict your provider access. Another may keep your premiums low but require prior authorizations for common services. That’s why you need a full-picture view before you enroll.

What CMS Star Ratings Really Reflect

Every year, the Centers for Medicare & Medicaid Services (CMS) publishes star ratings for Medicare Advantage plans. These ratings range from 1 to 5 stars and assess things like:

• Preventive care access

• Member complaints

• Customer service quality

• Chronic condition management

While a 5-star plan sounds like a safe bet, it doesn’t mean the plan fits your situation. You might find a 4-star plan offers better local access to care or lower copays for the services you actually use. Star ratings are a helpful metric, but they’re not the only factor to base your decision on.

Features That Seem Great—Until You Look Closer

Medicare Advantage plans often promote features that sound appealing. However, many of them come with caveats. Here’s what to be aware of in 2025:

Limited Provider Networks

Many Medicare Advantage plans operate within a Health Maintenance Organization (HMO) or Preferred Provider Organization (PPO) model. That means:

• HMO plans typically require you to use doctors and hospitals in the plan’s network.

• PPO plans offer some flexibility but charge more for out-of-network services.

If your preferred provider is not in the network, you may have to choose between paying more or switching doctors altogether. In rural areas, network limitations can be even more significant.

Prior Authorization Rules

Plans continue to use prior authorizations to manage costs and care. In 2025, this practice remains widespread. It means you often need pre-approval before receiving:

• Advanced imaging (e.g., MRI or CT scans)

• Certain prescription drugs

• Home health services

• Non-urgent surgeries

Prior authorizations can lead to treatment delays or even denials. For chronic or complex conditions, this can become a frustrating barrier to timely care.

Out-of-Pocket Maximums Vary

While all Medicare Advantage plans have a maximum out-of-pocket limit for in-network services (capped at $9,350 in 2025), not all plans approach that cap equally. Some set their limit much lower, while others hover close to the maximum.

Importantly, this out-of-pocket maximum does not always include:

• Out-of-network costs

• Prescription drugs (those follow Part D rules)

• Supplemental benefits

You need to understand how your plan structures these limits to gauge your real potential financial exposure.

Supplemental Benefits Come with Restrictions

Plans frequently market extra benefits like dental, hearing, vision, and fitness memberships. These are attractive perks, but:

• Dental coverage may only apply to cleanings and basic exams, not major services like crowns or implants.

• Vision coverage often limits your frame allowance or restricts you to specific retailers.

• Fitness benefits may not be useful if your local gym is not included.

Check the benefit details before assuming they’ll meet your actual needs.

The Role of Prescription Drug Coverage in 2025

Most Medicare Advantage plans include Part D prescription drug coverage. This year, the landscape has changed significantly:

• There is now a $2,000 cap on out-of-pocket prescription drug costs under Part D.

• The coverage gap or “donut hole” has been eliminated.

• A new monthly payment option allows you to spread out drug costs over the year.

These are major improvements, but plan formularies (the list of covered drugs) and tiered copays still vary widely. A drug you rely on could be in a higher cost tier or require prior authorization.

Network and Geography Still Dictate Access

Even in 2025, geography plays a major role in what plans are available and how useful they are. A plan rated 5 stars nationally might have limited reach in your ZIP code.

Factors that vary by region include:

• Network size and composition

• Access to specialists

• Availability of in-home or transportation services

Always verify the provider directory and local service availability before enrolling.

Comparing Medicare Advantage vs. Original Medicare

Understanding what you give up with Medicare Advantage is just as important as knowing what you gain. With Original Medicare, you get:

• National access to providers who accept Medicare

• No prior authorization for most services

• Separate enrollment in a standalone Part D plan

• Optional Medigap coverage for cost-sharing

With Medicare Advantage, you typically receive all-in-one coverage, but within a tighter framework. It may work well if you’re healthy and your preferred providers are in-network. It’s less ideal if you travel frequently or require frequent specialty care.

Why Plan Reviews Matter More Than Ever

In 2025, Medicare Advantage plans continue to evolve. Carriers introduce new benefits, remove others, or adjust cost-sharing annually. That’s why:

• The Annual Notice of Change (ANOC) is essential reading every fall.

• Star ratings are updated each October.

• Open Enrollment runs from October 15 to December 7.

Even if you liked your plan last year, you should review it again this year. Benefits, networks, and drug coverage may have changed significantly.

Timing Your Decision and Enrollment Periods

Understanding the right timeline for decision-making is crucial. Here are the enrollment windows for 2025:

• Initial Enrollment Period: Begins 3 months before your 65th birthday, ends 3 months after.

• Annual Enrollment Period: October 15 to December 7. You can join, switch, or drop a plan.

• Medicare Advantage Open Enrollment: January 1 to March 31. Allows you to change from one MA plan to another or return to Original Medicare.

Outside of these times, you generally need a Special Enrollment Period triggered by events such as moving, losing other coverage, or qualifying for Medicaid.

Making Trade-Offs That Work for You

There is no universal best plan. Every Medicare Advantage plan involves:

• Giving up something in exchange for a benefit

• Deciding whether cost-sharing aligns with your healthcare usage

• Understanding whether your current doctors and medications are covered

Ask yourself:

• Do you prefer lower monthly costs or broader provider access?

• Are your medications on the plan’s formulary?

• How often do you see specialists or require diagnostic tests?

Your answers will lead you to a plan that may not be perfect, but suits your specific circumstances.

Finding Help When the Details Feel Overwhelming

Medicare Advantage decisions are not just about benefits. They’re about how coverage feels when you need it most. If you’re unsure about plan networks, cost-sharing details, or prescription coverage, you’re not alone.

No One-Size-Fits-All Plan, and That’s the Point

Choosing a Medicare Advantage plan in 2025 is about trade-offs—not perfection. What works for someone else might not suit your health, budget, or lifestyle. Star ratings, supplemental benefits, and premiums all matter, but they are only part of the equation.
