Key Takeaways

• Medicare Advantage plans may advertise extra benefits, but many of these come with conditions, limitations, or trade-offs that are not highlighted in promotional materials.

• Understanding how provider networks, prior authorizations, and out-of-pocket caps work in 2025 can help you make more informed decisions before enrolling.

The Allure of Medicare Advantage Ads—and What They Leave Out

If you’ve watched TV, checked your mail, or browsed the internet during Medicare Open Enrollment season, you’ve likely seen countless ads promising impressive benefits under Medicare Advantage plans. These plans often promote vision, dental, hearing, gym memberships, and more—all sounding better than Original Medicare. But what these ads don’t tell you matters just as much as what they do.

In 2025, it’s more important than ever to look past the marketing and understand the mechanics of how these plans actually function. Let’s take a closer look at the information that’s often missing from the ads—and why it matters to you.

Provider Networks: Bigger Isn’t Always Better

One of the biggest trade-offs in Medicare Advantage plans is the use of provider networks. Unlike Original Medicare, which allows you to see any doctor or specialist who accepts Medicare, Advantage plans usually require you to stay within a specific network.

• HMO (Health Maintenance Organization) plans typically require you to see doctors within the plan’s network and may need referrals to see specialists.

• PPO (Preferred Provider Organization) plans offer more flexibility but may charge higher costs if you go out of network.

If your preferred doctor or hospital isn’t in the plan’s network, you could face full costs or be forced to switch providers. These details are rarely mentioned in advertisements.

Prior Authorization: A Common but Hidden Hurdle

Another significant limitation that ads don’t explain is prior authorization. In 2025, almost all Medicare Advantage plans require prior approval for many services, including:

• MRIs and CT scans

• Skilled nursing facility stays

• Home health care

• Some outpatient surgeries

This means your doctor must get the green light from the insurance company before you receive these services. Delays can occur, and some requests may even be denied. This can directly affect the timing and accessibility of care, but it’s rarely part of promotional messaging.

Out-of-Pocket Costs: They Add Up Fast

While some Medicare Advantage plans market themselves as low-cost options, the reality is that your out-of-pocket costs can add up quickly. In 2025:

• The maximum out-of-pocket limit for in-network care is $9,350.

• For combined in- and out-of-network care (in PPOs), the limit can reach $14,000.

Even though these limits are meant to protect you, they’re still much higher than what many people expect—especially if you need ongoing care or have a major health event. Ads rarely discuss these caps or the expenses that lead up to them.

Benefits That Sound Generous—Until You Read the Fine Print

Many Advantage plan ads highlight extra benefits like dental cleanings, hearing aids, or eyeglasses. What’s often omitted is the scope and limits of these services:

• Dental: May only cover basic cleanings or x-rays, not crowns, root canals, or dentures.

• Hearing: Might include hearing exams but limit hearing aid options or only offer discounts.

• Vision: May cover annual exams but restrict eyewear allowances to specific vendors.

So while the extras sound great in theory, they may not fully meet your needs in practice.

Prescription Drug Coverage: Convenience Comes with Rules

Most Medicare Advantage plans include Part D prescription drug coverage, which seems like a plus. However, not all formularies are the same. Ads rarely mention that:

• Some medications may require prior authorization.

• Drugs can be placed in high-cost tiers.

• Preferred pharmacies may be limited.

Additionally, starting in 2025, the new $2,000 out-of-pocket cap for Part D does apply to Advantage plans with drug coverage—but only once you’ve met the deductible and progressed through the initial coverage phase. This cap can be helpful, but how you reach it matters.

Supplemental Benefits: Not Always Guaranteed

Many plans highlight benefits like meal delivery, transportation to appointments, or over-the-counter (OTC) allowances. However, these benefits:

• Often have usage restrictions (e.g., a limited number of rides per year).

• May be offered only to members with chronic conditions.

• Can require you to use certain vendors.

In other words, not everyone qualifies, and the benefit may not be as flexible or useful as it first appears.

Emergency and Travel Coverage: Limited in Scope

Another point that’s often overlooked in advertising is the limitation of coverage outside your home service area. While emergency care is usually covered, non-emergency services while traveling may not be:

• You might be responsible for full costs if you seek care out of network.

• Snowbirds and frequent travelers may find coverage gaps if their plan doesn’t extend beyond a local region.

Make sure you check the travel rules of any plan you’re considering, especially if you spend time in multiple states.

Enrollment Timing and Lock-In Rules

Medicare Advantage plans have specific enrollment periods and lock-in rules that limit your ability to make changes:

• Initial Enrollment Period (IEP): Begins three months before the month you turn 65 and ends three months after.

• Annual Enrollment Period (AEP): From October 15 to December 7, changes go into effect January 1.

• Medicare Advantage Open Enrollment (MA-OEP): From January 1 to March 31, you can switch Advantage plans or return to Original Medicare.

Outside these windows, you generally need a Special Enrollment Period (SEP) to make changes. Ads typically gloss over these limitations.

Star Ratings and Plan Quality: Not All Plans Are Equal

Medicare assigns star ratings to Advantage plans based on quality and performance metrics. These range from 1 to 5 stars. While some plans highlight their star ratings, others don’t—often because they’re average or below.

In 2025, choosing a plan with a 4-star rating or higher can increase your chances of better service and fewer issues. But that information is not always front-and-center in marketing materials.

Customer Support and Appeals Process

One of the more hidden aspects of Medicare Advantage is how customer service works when things go wrong:

• Appeals can take time, especially for denied services.

• Customer support varies by plan and provider.

• Resolution of disputes isn’t always straightforward.

These are things you may only learn about when a problem arises—and by then, switching plans may not be possible.

Why This Matters in 2025

As of 2025, Medicare Advantage enrollment continues to grow, and the number of available plans remains high. However, the complexity of coverage options and plan differences has also increased. You can no longer rely on advertising alone to make a confident decision.

This year, more than ever, you need to:

• Review each plan’s Evidence of Coverage (EOC) document.

• Check the provider and pharmacy network.

• Verify coverage for your medications.

• Understand out-of-pocket risks.

• Ask about prior authorization requirements.

The burden is on you to gather the full picture before you enroll.

Take the Time to Review What Ads Leave Out

Marketing materials may catch your attention, but they’re not a substitute for real information. The benefits you see promoted may be genuine, but the details behind them can change the value you receive. If you only rely on ads, you risk making a decision that could affect your access to care, your out-of-pocket costs, and your peace of mind for the entire year.

Take your time. Review carefully. And don’t hesitate to ask questions before committing to a Medicare Advantage plan.
