Key Takeaways

• Medicare Advantage plans in 2025 offer a mix of valuable benefits and cost-saving features, but understanding the limitations is essential before enrolling.

• The highest-rated plans receive 4 to 5 stars from the Centers for Medicare & Medicaid Services (CMS), but a high rating doesn’t guarantee that the plan meets your specific healthcare needs.

What Makes a Medicare Advantage Plan Stand Out in 2025?

Medicare Advantage plans, also known as Part C, combine Medicare Part A (hospital insurance) and Part B (medical insurance) into one comprehensive plan. Many also include Part D prescription drug coverage and supplemental benefits like dental, vision, and hearing care. In 2025, more than 30 million Americans are enrolled in Medicare Advantage, and the plans continue to evolve with new features, cost structures, and member services.

Some of the standout features of Medicare Advantage plans this year include:

• Annual out-of-pocket maximums for in-network services, offering protection against catastrophic costs

• Coverage for additional services not included in Original Medicare, such as fitness memberships and over-the-counter item allowances

• Care coordination through primary care doctors or care managers

• Telehealth coverage for both primary and specialty care

• Extra support for managing chronic conditions, including personalized care plans

But while these benefits can be appealing, it’s crucial to dig into the details.

The Role of CMS Star Ratings

The Centers for Medicare & Medicaid Services (CMS) uses a 5-star rating system to evaluate the quality and performance of Medicare Advantage plans. These ratings are based on various metrics such as:

• Preventive care and screenings

• Management of chronic conditions

• Member complaints and disenrollment rates

• Customer service responsiveness

• Drug safety and adherence (for plans that include Part D)

A 5-star plan is considered excellent, while 4 stars indicate above-average performance. In 2025, CMS continues to emphasize patient outcomes, customer experience, and access to care. However, even a highly rated plan may not be the right fit for your personal healthcare situation. It’s best to use the rating as one part of a broader evaluation.

Hidden Limits and Network Rules

Medicare Advantage plans are known for their network-based models. Most plans operate as either Health Maintenance Organizations (HMOs) or Preferred Provider Organizations (PPOs):

• HMOs typically require you to choose a primary care provider and get referrals for specialists. They may not cover any out-of-network services except in emergencies.

• PPOs offer more flexibility with providers, allowing you to see out-of-network doctors at a higher cost.

Understanding these structures matters. You may find a low-premium plan that looks appealing but discover that your preferred doctors and hospitals aren’t in the network.

In addition, many plans use prior authorization, meaning you need approval before receiving certain treatments or medications. In 2025, prior authorization remains a common source of delays and denials, especially for specialist visits and advanced imaging tests.

Supplemental Benefits: Helpful or Just Flashy?

Medicare Advantage plans often advertise their supplemental benefits heavily. These may include:

• Dental cleanings and procedures

• Vision exams and eyeglasses

• Hearing tests and hearing aids

• Transportation to medical appointments

• Allowances for groceries or meals after hospital stays

These extras sound impressive, but you need to examine how they work:

• Are the benefits available year-round or just once annually?

• Are you limited to certain providers or vendors?

• What are the benefit caps or coverage limits?

In 2025, CMS continues to allow flexibility in how these benefits are offered, but plan designs vary widely. Two plans may advertise dental coverage, but one might cover only preventive care while the other includes extractions and root canals. Always read the fine print.

Prescription Drug Coverage and Out-of-Pocket Costs

If your Medicare Advantage plan includes Part D drug coverage, you need to evaluate its formulary (list of covered drugs), tier structure, and cost-sharing requirements. In 2025, the Part D landscape includes major updates:

• An annual out-of-pocket cap of $2,000 on prescription drugs

• No more coverage gap (donut hole)

• Monthly payment options for drug expenses to spread out costs

These changes offer significant relief, but each plan manages drug coverage differently. A drug in Tier 1 under one plan could be in Tier 3 under another, affecting your copays or coinsurance.

Some plans use step therapy, requiring you to try lower-cost drugs before moving to more expensive ones. Make sure you understand what’s required to avoid surprises when filling prescriptions.

Coordination with Medicare Part B

Medicare Advantage plans must provide at least the same benefits as Original Medicare Parts A and B. But how they deliver those services can differ. You’ll need to examine:

• Whether the plan requires copayments for services that are fully covered under Original Medicare

• If certain screenings or services have stricter frequency limitations

• Whether durable medical equipment and outpatient services involve extra authorization or paperwork

In 2025, many plans continue offering lower cost-sharing for preventive services but may offset that by charging more for specialist visits, outpatient surgeries, or high-tech scans.

Travel and Emergency Coverage

One commonly overlooked factor is how your plan handles travel. If you travel frequently or live in different areas during the year (such as snowbird migration), you need to understand:

• Whether your plan offers nationwide network access

• How emergency and urgent care is handled out of state

• If the plan provides any international travel coverage (many do not)

Some PPOs in 2025 offer broad regional or national networks, but most HMOs remain highly local. Relying on a plan with strict geographic restrictions can cause problems if you move or travel often.

Annual Enrollment and Switching Options

You can generally enroll in or switch Medicare Advantage plans during specific windows:

• Initial Enrollment Period (IEP): A 7-month window around your 65th birthday

• Annual Enrollment Period (AEP): October 15 to December 7 each year

• Medicare Advantage Open Enrollment Period (MA OEP): January 1 to March 31, only for people already enrolled in a Medicare Advantage plan

In some cases, Special Enrollment Periods (SEPs) allow changes due to life events such as moving, losing other coverage, or plan termination.

CMS allows a one-time switch to a 5-star plan at any time during the year if one is available in your area. That can be helpful, but availability varies by ZIP code.

How to Evaluate Whether a Plan Is Truly a Good Fit

With so many moving parts, evaluating a Medicare Advantage plan requires more than scanning the summary brochure. Consider the following checklist:

• Is your primary care provider and preferred specialists in-network?

• Are your current prescriptions covered and affordable under the plan?

• Are hospitals, clinics, and pharmacies near you participating?

• How high is the plan’s in-network out-of-pocket maximum?

• Do the supplemental benefits match your needs, or are they just marketing features?

• Does the plan require referrals or prior authorization for services you routinely use?

• Are the monthly premiums (if any) offset by higher cost-sharing elsewhere?

You should also compare CMS star ratings for insight into plan quality and complaints. But remember, the “best” plan on paper might not be best for your lifestyle, conditions, or healthcare providers.

Make Your Decision Based on Clarity, Not Just Convenience

Enrolling in a Medicare Advantage plan isn’t a one-time choice you can forget. Plans change annually. Provider networks adjust. Drug formularies shift. What works for you today may not serve you well next year.

In 2025, more than ever, you need to carefully review your Annual Notice of Change (ANOC) document each fall. It outlines the updates to your current plan, including:

• Changes in premiums, deductibles, and copays

• Updates to drug coverage and provider networks

• Adjustments to supplemental benefit availability

Even if your health hasn’t changed, your plan might have. Take the time to review and compare.

Understanding the Fine Print Can Save You Headaches Later

Medicare Advantage plans can offer valuable coverage and convenience, but only when chosen wisely. A high CMS rating, attractive benefits, and low upfront costs mean little if your doctors aren’t covered, your prescriptions cost more, or you face restrictions you didn’t anticipate.

Before enrolling, evaluate the full picture:

• Look beyond the highlights and examine exclusions and conditions

• Prioritize access to care, not just perks

• Assess plan flexibility, especially if you travel or have multiple providers
