Key Takeaways

• Medicare Advantage and Medicare Supplement (Medigap) plans both help cover healthcare costs, but they function very differently. Understanding their pros and cons will help you decide which fits your needs in 2025.

• Medicare Advantage plans typically bundle coverage and offer extra benefits, while Supplement plans fill in the gaps of Original Medicare to reduce out-of-pocket expenses.

Understanding Your Options: Medicare Advantage vs. Supplement Plans

If you’re looking at your Medicare choices in 2025, you might be wondering: Should you go with a Medicare Advantage plan or stick with Original Medicare and add a Supplement plan (also called Medigap)? The right decision depends on what kind of coverage, flexibility, and cost structure you prefer. Let’s break it all down so you can make an informed choice.

What Are Medicare Advantage Plans?

Medicare Advantage plans (Part C) are an all-in-one alternative to Original Medicare. These plans are offered by private insurance companies approved by Medicare and must provide at least the same coverage as Part A (hospital insurance) and Part B (medical insurance). Many Medicare Advantage plans also include prescription drug coverage (Part D) and extra benefits like dental, vision, and wellness programs.

Pros of Medicare Advantage Plans

• Bundled Coverage: Most Medicare Advantage plans include Part A, Part B, and often Part D, giving you all-in-one healthcare coverage.

• Extra Benefits: Some plans provide additional perks like dental, vision, hearing, and wellness services, which Original Medicare does not cover.

• Fixed Out-of-Pocket Maximums: Medicare Advantage plans have an annual out-of-pocket limit, meaning once you reach that amount in covered medical expenses, the plan pays 100% of covered costs for the rest of the year.

• Lower Monthly Premiums in Some Cases: Depending on the plan, you may pay lower monthly premiums than you would with a Medigap policy, but this varies based on the plan and coverage options.

Cons of Medicare Advantage Plans

• Provider Network Restrictions: Many Medicare Advantage plans require you to use a network of doctors and hospitals, which can limit your provider choices.

• Referral Requirements: Some plans, especially HMOs, require referrals from a primary care physician before you can see a specialist.

• Potential Higher Out-of-Pocket Costs: While Medicare Advantage has a maximum out-of-pocket limit, you may still have copays, deductibles, and coinsurance costs throughout the year.

• Changes in Benefits and Coverage: Plan benefits, provider networks, and costs can change annually, requiring you to review your plan every year.

What Are Medicare Supplement Plans (Medigap)?

Medicare Supplement (Medigap) plans are designed to help cover costs that Original Medicare doesn’t pay for, such as copayments, coinsurance, and deductibles. These plans work alongside Original Medicare and can help reduce out-of-pocket expenses.

Pros of Medicare Supplement Plans

• Freedom to Choose Any Provider: Medigap plans allow you to visit any doctor or hospital that accepts Medicare, without network restrictions.

• Predictable Costs: These plans help reduce unexpected medical bills by covering out-of-pocket costs like deductibles and copays.

• No Referrals Required: You don’t need a referral to see a specialist, which gives you more control over your healthcare choices.

• Coverage is Stable: Once enrolled, Medigap plans generally do not change benefits or coverage from year to year, unlike Medicare Advantage plans.

Cons of Medicare Supplement Plans

• Higher Monthly Premiums: Medigap plans usually have higher monthly costs than Medicare Advantage plans, which may not be affordable for everyone.

• No Extra Benefits: Unlike Medicare Advantage, Medigap does not include vision, dental, or prescription drug coverage. You will need a separate Part D plan for medications.

• Limited Enrollment Periods: The best time to enroll in a Medigap plan is during your six-month Medigap Open Enrollment Period when you first sign up for Medicare Part B. After that, you may be subject to medical underwriting, which can affect your eligibility or costs.

Comparing Costs in 2025: Which Plan Saves You More?

While both options help cover healthcare costs, they do so in different ways. Medicare Advantage plans often have lower or no additional monthly premiums but require copays and coinsurance when you receive services. Medigap plans, on the other hand, come with higher monthly premiums but significantly reduce out-of-pocket expenses when you need medical care.

What to consider:

• If you visit doctors often and need frequent medical services, a Medigap plan might save you money in the long run by covering deductibles and copays.

• If you prefer lower monthly premiums and don’t mind copays for services, Medicare Advantage may be a better option.

• If you need additional benefits like dental and vision, Medicare Advantage is the only option that includes them.

• If you want stable coverage and provider freedom, Medigap is the better choice.

Can You Switch Between Medicare Advantage and Medigap?

Yes, but there are rules. If you start with a Medicare Advantage plan and later decide you want a Medigap policy, you may face underwriting requirements unless you qualify for a special enrollment period. Likewise, if you leave a Medigap plan for Medicare Advantage, you may not be able to switch back later without restrictions.

The best time to make your choice is during Medicare Open Enrollment (October 15 – December 7) each year, when you can switch plans or return to Original Medicare. Special Enrollment Periods (SEPs) may apply in certain circumstances, like moving out of your plan’s service area or losing employer coverage.

Making the Right Choice for Your Needs

Deciding between Medicare Advantage and Medigap comes down to what matters most to you:

• Do you prioritize provider flexibility and predictable costs? Medigap might be the best option.

• Do you want additional benefits and lower monthly costs? Medicare Advantage may suit you better.

• Do you travel frequently? Medigap provides better nationwide coverage, while many Medicare Advantage plans have geographic limitations.

• Do you expect high medical expenses? Medigap may save you more in out-of-pocket costs.
