Quick Takeaway
For many people entering Medicare, one of the biggest decisions isn’t whether to get Medicare.
It’s how to receive and supplement that coverage.
The two commonly compared approaches are:
Medicare Advantage (Part C)
versus
Original Medicare + Medicare Supplement Insurance (Medigap)
Medicare Advantage may have a lower monthly premium and often bundles prescription-drug coverage and additional benefits. Medigap generally costs an additional monthly premium but can substantially reduce certain out-of-pocket costs under Original Medicare and gives you access to any U.S. doctor or hospital that accepts Medicare.
So which saves more?
There isn’t one answer for everyone.
Medicare Advantage may save more in premiums.
Medigap may provide greater cost predictability when you need significant Medicare-covered healthcare.
The better financial choice depends on your health, location, doctors, prescriptions, travel habits, budget and tolerance for unexpected medical bills.
First: Medicare Advantage and Medigap Are Not the Same Thing
This distinction is essential.
Medicare Advantage
Medicare Advantage is an alternative way to receive your Medicare Part A and Part B benefits through a Medicare-approved private company.
Plans often bundle:
Part A + Part B + usually Part D prescription-drug coverage.
Many plans also offer benefits that Original Medicare doesn’t routinely cover, which may include:
Dental
Vision
Hearing
and other supplemental benefits.
You still need Medicare Parts A and B to join a Medicare Advantage plan.
Medicare Supplement
Medicare Supplement Insurance—commonly called Medigap—works differently.
It doesn’t replace Original Medicare.
It supplements it.
Original Medicare pays its share of Medicare-approved covered services, and your Medigap policy can help pay eligible remaining expenses such as:
Copayments
Coinsurance
and certain:
Deductibles.
You generally need both Medicare Part A and Part B to purchase Medigap.
You Cannot Use Medicare Advantage and Medigap Together
This is one of the most important rules to understand.
You generally choose:
Option A
Medicare Advantage
OR
Option B
Original Medicare + Medigap
You cannot use a Medigap policy to pay the deductibles, copayments or premiums of a Medicare Advantage plan.
So this isn’t really a comparison of two policies that can be stacked together.
It’s a comparison of two different approaches to Medicare coverage.
Medicare Advantage vs. Medicare Supplement at a Glance
| Feature | Medicare Advantage | Original Medicare + Medigap |
|---|---|---|
| Basic Medicare coverage | Through private Medicare-approved plan | Original Medicare |
| Additional monthly premium | Can be $0 for some plans; varies | Medigap premium required |
| Part B premium | Still generally required | Required |
| Prescription drugs | Usually included | Separate Part D generally needed |
| Provider network | Often applies | Any provider accepting Medicare |
| Referrals | May be required | Usually not |
| Prior authorization | May apply | Original Medicare generally requires less |
| Annual medical out-of-pocket limit | Yes for covered Medicare services | Medigap reduces eligible Original Medicare cost-sharing based on plan |
| Dental/Vision/Hearing | Often available as extra benefits | Generally not covered by Medigap |
| Nationwide provider flexibility | More limited depending on plan | Strong |
| Foreign travel | Depends on plan | Some Medigap plans provide limited foreign emergency coverage |
| Predictability | Costs vary as services are used | Often more predictable depending on Medigap plan |
| Separate Part D plan | Usually unnecessary | Usually needed for drug coverage |
The 2026 Medicare Costs Everyone Should Know
Regardless of which option you choose, Medicare Part B remains an important expense.
For 2026, CMS has set the standard Medicare Part B premium at:
$202.90 per month
The annual Part B deductible is:
$283.
Higher-income beneficiaries may pay more because of the income-related monthly adjustment amount, commonly called IRMAA.
The 2026 Medicare Part A inpatient hospital deductible is:
$1,736 per benefit period.
These numbers help explain why many beneficiaries look for either Medicare Advantage or Medigap rather than relying on Original Medicare alone.
Where Medicare Advantage Can Save Money
The most obvious advantage is the potential monthly premium.
Some Medicare Advantage plans charge:
$0 additional plan premium.
That does not mean Medicare itself is free.
You generally still pay your Medicare Part B premium.
But compared with paying:
Part B premium + Medigap premium + potentially a separate Part D premium,
a $0-premium Medicare Advantage plan can look financially attractive.
Medicare confirms that some Medicare Advantage plans have a $0 premium, although costs and benefits vary by plan.
Example: The Healthy Retiree
Consider Robert.
Age: 67
Robert rarely visits doctors beyond routine appointments.
Suppose he has access to a Medicare Advantage plan with:
$0 additional monthly premium
and his doctors participate in its network.
If Robert uses relatively little healthcare during the year, Medicare Advantage could potentially result in lower total annual spending than paying a substantial Medigap premium every month.
But there is a trade-off.
If Robert later requires:
specialists + imaging + outpatient procedures + hospital care + rehabilitation,
his cost-sharing could increase considerably, subject to the plan’s annual limit.
That’s why comparing premiums alone can be misleading.
Medigap Takes the Opposite Approach
Medigap generally asks you to pay:
more predictable premiums upfront
in exchange for:
less exposure to certain Original Medicare out-of-pocket expenses.
For example, depending on the standardized Medigap plan selected, coverage can help pay:
Part A coinsurance
Part B coinsurance
Part A deductible
Skilled nursing facility coinsurance
and other eligible Medicare cost-sharing.
Coverage differs among standardized plan letters.
This makes Medigap attractive to people who value:
predictability.
Example: The Frequent Healthcare User
Consider Susan.
Age: 72
She regularly sees:
A cardiologist
An endocrinologist
An orthopedic specialist
and:
Her primary-care physician.
She also undergoes regular testing.
A low-premium Medicare Advantage plan could still work for Susan.
But she needs to investigate:
Specialist copays
Hospital costs
Imaging costs
Network participation
Prior authorization
and:
Maximum annual out-of-pocket exposure.
With an appropriate Medigap policy, Susan may pay a higher monthly premium but face less Medicare cost-sharing for covered services.
For someone who regularly uses healthcare, that predictability can have significant value.
The Biggest Medigap Advantage: Provider Freedom
This can be more important than price.
With Original Medicare, you can generally see any doctor or hospital in the United States that accepts Medicare.
Medicare Advantage plans may require you to use providers within the plan’s:
Network
and:
Service area
for non-emergency care.
Some plans allow out-of-network care, but it may cost more.
Imagine you live in:
Arizona
but spend four months each year with family in:
Florida.
Or perhaps you want treatment at a major specialist center in another state.
Original Medicare plus Medigap may provide greater flexibility.
HMO vs. PPO Matters With Medicare Advantage
Not all Medicare Advantage plans have the same network structure.
Two common designs are:
HMO
A Health Maintenance Organization generally emphasizes in-network providers.
Out-of-network non-emergency care may have limited or no coverage, depending on plan rules.
PPO
A Preferred Provider Organization generally provides more flexibility to use out-of-network providers, although doing so may cost more.
Therefore, don’t simply ask:
“Is Medicare Advantage cheaper?”
Ask:
“Is this particular Medicare Advantage plan cheaper for the doctors and hospitals I actually want to use?”
Medicare Advantage Has an Annual Out-of-Pocket Limit
This is an important protection.
Original Medicare by itself doesn’t have an annual out-of-pocket maximum for Part A and Part B services.
Medicare Advantage plans do have yearly limits on what members pay for covered Medicare services. After reaching the applicable plan limit, the beneficiary pays nothing for covered services for the remainder of that year, subject to plan terms.
The exact maximum varies by plan within Medicare rules.
When comparing plans, don’t look only at:
Monthly Premium: $0
Look for:
Maximum Out-of-Pocket: $____
That number represents an important part of your financial exposure.
Why $0 Premium Doesn’t Mean $0 Healthcare Costs
This is perhaps the biggest Medicare Advantage misunderstanding.
A $0-premium plan could still have:
Primary-care copays
Specialist copays
Hospital cost-sharing
Emergency-room copays
Imaging costs
Outpatient surgery costs
Drug costs
and:
Out-of-network costs.
Think of it as:
Low fixed cost + potentially higher variable cost
rather than:
Free healthcare.
Medigap Premiums Work Differently
With Medigap, you pay a private insurance company an additional monthly premium.
The amount varies based on factors including:
Plan
Insurance company
Location
and potentially:
Age or rating method.
Medicare notes that Medigap premiums vary and can change each year.
Two insurers may sell the same standardized Medigap plan at different prices.
This is important because standardized plans with the same letter generally provide the same standardized benefits regardless of the company selling them.
So price comparison matters.
Plan G Is Popular—but Understand What It Does
Medigap Plan G provides broad standardized coverage.
However, it does not pay the Medicare Part B deductible.
For 2026, that deductible is:
$283.
After satisfying the applicable deductible, Plan G can cover substantial Original Medicare cost-sharing according to its standardized benefits.
Premiums still vary by insurer and location.
What About Plan F?
Plan F offers very comprehensive standardized benefits, but it isn’t available to everyone.
Medicare states that Plan F and Plan C aren’t available to people who became newly eligible for Medicare on or after:
January 1, 2020.
People eligible before that date may still potentially qualify depending on circumstances.
New Medicare beneficiaries in 2026 therefore generally won’t have Plan F as an option.
High-Deductible Plan G
Some states and insurers offer a high-deductible version of Plan G.
For 2026, Medicare lists the high-deductible Plan G amount as:
$2,950.
You pay Medicare-covered costs up to the applicable deductible amount before the policy begins paying according to its terms.
This can create an interesting middle ground:
Lower premium
but:
Greater upfront cost exposure.
For relatively healthy retirees who want Original Medicare’s provider flexibility, it can be worth comparing.
Prescription Drugs: Medicare Advantage Has an Advantage in Convenience
Most Medicare Advantage plans include:
Part D prescription-drug coverage.
That means:
Medical + hospital + prescription coverage
can often be bundled into one plan.
Medigap doesn’t work that way.
Medigap policies sold after 2005 don’t include prescription-drug coverage. If you want prescription coverage alongside Original Medicare and Medigap, you generally need a separate:
Medicare Part D plan.
So your Medigap setup could involve:
Part A + Part B + Medigap + Part D.
This can mean more separate premiums and policies.
Don’t Compare Drug Coverage by Premium Alone
If you’re considering Medicare Advantage with prescription coverage or a standalone Part D plan, check your actual medications.
Look at:
Formulary
Drug tier
Deductible
Copayment
Coinsurance
Preferred pharmacies
and:
Prior authorization requirements.
A plan with a slightly higher premium could potentially save more if it covers your medications more favorably.
Dental, Vision and Hearing
Medicare Advantage frequently receives attention because many plans provide supplemental benefits that Original Medicare generally doesn’t cover.
These may include:
Routine dental
Routine vision
Hearing benefits
and other extras.
Medigap generally doesn’t cover:
Routine dental care
Vision care
Hearing aids
or:
Eyeglasses.
But don’t choose Medicare Advantage simply because the brochure says:
“Dental Included.”
Check:
Annual allowance
Provider network
Covered procedures
Frequency limits
and:
Cost-sharing.
The value of these benefits varies considerably.
Prior Authorization Can Be a Major Difference
Original Medicare generally doesn’t require prior authorization as often as Medicare Advantage plans.
Medicare notes that Medicare Advantage beneficiaries may need plan approval before certain services or supplies are covered.
For someone who values flexibility and fewer plan-level authorization requirements, this can make Original Medicare plus Medigap more attractive.
For another person, lower premiums may outweigh that concern.
Frequent Travelers Should Pay Attention
Suppose you’re retired and regularly travel around the United States.
With Original Medicare:
You can generally use any doctor or hospital that accepts Medicare nationwide.
A Medicare Advantage plan may have a more geographically limited provider network for routine non-emergency care.
That doesn’t necessarily make Medicare Advantage unsuitable for travelers.
Emergency and urgent coverage has different protections.
But people who spend months away from home should carefully examine network rules.
What About International Travel?
Original Medicare generally doesn’t cover healthcare outside the United States except in limited circumstances.
However, certain Medigap plans provide limited:
Foreign travel emergency coverage.
Some Medicare Advantage plans may also provide supplemental emergency or urgent-care benefits abroad.
Frequent international travelers should compare these provisions carefully.
Neither should automatically be treated as comprehensive international health insurance.
The Biggest Medigap Trap: Waiting Too Long
This is crucial.
Your federal Medigap Open Enrollment Period generally lasts:
6 months
starting the first month you’re:
65 or older
and enrolled in:
Medicare Part B.
During this period, you can buy any Medigap policy sold in your state without being denied due to pre-existing health problems.
After this period ends, federal rules generally don’t guarantee that you’ll always be able to buy any Medigap plan you want.
Unless you have a guaranteed-issue right or other protections apply, insurers may potentially:
Use medical underwriting
Charge more
or:
Decline your application.
State rules can provide additional protections.
Don’t Assume You Can Try Medicare Advantage and Easily Buy Medigap Years Later
This is a common planning mistake.
Someone might think:
“I’ll choose the cheapest Medicare Advantage plan now. If my health gets worse later, I’ll switch to Original Medicare and buy Medigap.”
That strategy can be risky.
Depending on your circumstances, timing and state law, you may not have guaranteed access to the Medigap policy you want later.
There are specific:
Trial rights
and:
Guaranteed-issue protections
in certain situations.
But they don’t apply universally.
Your initial Medicare decision can therefore have long-term consequences.
Scenario 1: Healthy 65-Year-Old on a Tight Budget
Consider Mark.
Age: 65
Health: Generally good
Doctors: Local
Travel: Limited
Priority: Lowest monthly premium
A Medicare Advantage plan with:
$0 or low additional premium
could potentially save Mark money in years when he uses little healthcare.
But he should still compare:
Maximum out-of-pocket exposure
Provider network
Drug costs
and:
Future flexibility.
Potential Winner:
Medicare Advantage
for lower current fixed costs.
Scenario 2: 72-Year-Old With Multiple Specialists
Consider Barbara.
Age: 72
She regularly sees:
Primary-care physician
Cardiologist
Neurologist
and:
Orthopedic specialist.
Her priority is:
Predictable healthcare costs + broad doctor access.
An appropriate Medigap policy could potentially make her Medicare-covered out-of-pocket expenses more predictable.
Potential Winner:
Medigap
depending on premiums and available coverage.
Scenario 3: Retired Couple Traveling Across America
John and Linda spend:
four months in Florida
three months in Michigan
and:
the rest of the year in Ohio.
They want easy access to Medicare-participating physicians wherever they travel.
Original Medicare plus Medigap may be particularly attractive because Original Medicare allows beneficiaries to use any doctor or hospital accepting Medicare across the U.S.
Potential Winner:
Medigap
for nationwide provider flexibility.
Scenario 4: Retiree Who Wants Everything Bundled
David doesn’t want to manage multiple plans.
He wants:
Medical
Hospital
Prescription drugs
plus potentially:
Dental + vision + hearing
under one plan.
Medicare Advantage may provide a more convenient bundled structure.
Potential Winner:
Medicare Advantage
for simplicity and supplemental benefits.
Scenario 5: Someone Who Hates Unexpected Bills
Susan has a comfortable retirement income.
She doesn’t necessarily need the cheapest monthly premium.
Her priority is knowing approximately how much healthcare will cost.
She would rather pay:
higher predictable premiums
than face:
multiple copays and variable medical expenses.
An appropriate Medigap plan may fit that preference better.
Potential Winner:
Medigap
for predictability.
Which Is Cheaper Over 10 Years?
This is where comparisons become difficult.
Suppose Medicare Advantage saves you:
$150/month
in premiums compared with a hypothetical Medigap alternative.
That’s:
$1,800/year
or:
$18,000 over 10 years
before considering premium changes.
Sounds excellent.
But suppose you later develop a condition requiring:
Frequent specialists
Outpatient procedures
Imaging
Hospitalizations
and:
Rehabilitation.
Your Medicare Advantage cost-sharing could absorb some of those premium savings.
Conversely, if you remain relatively healthy, you might spend thousands of dollars on Medigap premiums for benefits you use relatively little.
That’s the fundamental trade-off:
Medicare Advantage → lower fixed costs, potentially higher variable costs
Medigap → higher fixed costs, potentially lower and more predictable Medicare-covered cost-sharing.
Don’t Forget That Medigap Premiums Can Rise
Medigap isn’t a fixed lifetime price.
Medicare says Medigap premiums can change each year.
When comparing policies, understand the insurer’s pricing method.
Medigap pricing may be structured as:
Community-rated
Issue-age-rated
or:
Attained-age-rated,
depending on the policy and state.
Your premium trajectory matters just as much as today’s quote.
Your Doctor List May Decide the Winner
Before enrolling in Medicare Advantage, make a list of your:
Primary-care doctor
Cardiologist
Oncologist
Orthopedic specialist
Hospital
Specialty medical center
and other important providers.
Then verify participation directly with:
the plan
and preferably:
the provider.
Networks can change.
A $0-premium plan isn’t a bargain if it significantly restricts access to the doctors you want.
Your Prescription List May Decide It Too
Do the same thing with medications.
Write down:
Drug name
Dosage
Frequency
Preferred pharmacy.
Then compare your estimated annual drug costs.
For someone taking expensive prescriptions, medication coverage can outweigh a seemingly attractive medical premium.
Compare Total Annual Cost—Not Monthly Premium
This is the calculation that matters.
Medicare Advantage
Estimate:
Part B premium
Medicare Advantage premium
Medical copays/coinsurance
Prescription costs
Dental/vision costs not covered
=
Estimated Annual Cost
Original Medicare + Medigap
Estimate:
Part B premium
Medigap premium
Part D premium
Part D drug costs
Dental/vision costs
Remaining Medicare cost-sharing
=
Estimated Annual Cost
Compare both under:
Healthy year
Moderate healthcare year
and:
High healthcare-use year.
That provides a much more realistic comparison than looking only at premiums.
When Medicare Advantage May Save More
Medicare Advantage may be financially attractive when you:
- Want a low monthly premium.
- Are comfortable with provider networks.
- Primarily receive care locally.
- Have doctors participating in the plan.
- Want integrated Part D coverage.
- Value included supplemental benefits.
- Are comfortable with copays and variable expenses.
- Have reviewed the plan’s maximum out-of-pocket exposure.
When Medigap May Save More
Original Medicare plus Medigap may be attractive when you:
- Use healthcare frequently.
- Want predictable Medicare-covered costs.
- See multiple specialists.
- Travel frequently within the United States.
- Want broad access to Medicare-participating providers.
- Don’t want to depend heavily on a local provider network.
- Are comfortable paying a higher monthly premium.
- Want some foreign-travel emergency coverage available under certain Medigap plans.
What Medicare Advantage May Do Better
For many beneficiaries:
Lower monthly premiums
Bundled prescription coverage
Dental benefits
Vision benefits
Hearing benefits
Convenient plan structure
and:
Annual out-of-pocket protection.
Those are meaningful advantages.
What Medigap May Do Better
Depending on the standardized plan:
Reduced Original Medicare cost-sharing
Predictable medical expenses
Nationwide provider access
No restrictive Medicare Advantage provider network
and:
Potential foreign-travel emergency benefits.
Those are meaningful advantages too.

Frequently Asked Questions
Is Medicare Advantage cheaper than Medigap?
It can be. Medicare Advantage plans may have lower or even $0 additional premiums, while Medigap requires a separate premium. However, Medicare Advantage members can face copays and other cost-sharing as they use healthcare. The cheapest option depends on total annual costs, not premium alone.
Is Medicare Supplement the same as Medicare Advantage?
No. Medicare Advantage is another way to receive Medicare benefits. Medigap supplements Original Medicare by helping pay certain out-of-pocket costs.
Can I have Medicare Advantage and Medigap simultaneously?
You can’t use Medigap to pay Medicare Advantage copayments, deductibles or premiums. Medigap is designed to work with Original Medicare.
What is the Medicare Part B premium in 2026?
The standard Medicare Part B premium is $202.90 per month in 2026, although higher-income beneficiaries can pay more.
What is the Part B deductible in 2026?
The annual Medicare Part B deductible is $283 in 2026.
Does Medigap include prescription drugs?
Modern Medigap policies don’t include prescription-drug coverage. Beneficiaries who want drug coverage can generally enroll in a separate Medicare Part D plan.
Does Medicare Advantage include prescription coverage?
Most Medicare Advantage plans include Medicare Part D prescription-drug coverage.
Can I see any doctor with Medigap?
Medigap works with Original Medicare, which generally allows you to see any doctor or hospital in the United States that accepts Medicare.
Does Medigap cover dental and vision?
Generally, Medigap doesn’t cover routine dental, vision, hearing aids or eyeglasses.
Can I buy Medigap later if I choose Medicare Advantage first?
Possibly, but don’t assume you’ll always have guaranteed access. Outside certain protected situations, medical underwriting may apply after your Medigap Open Enrollment Period.
Final Verdict: Which Saves You More?
There is no universal winner.
Medicare Advantage may save more if:
You’re relatively healthy, want low monthly premiums, are comfortable with a local provider network and value bundled prescription, dental, vision or hearing benefits.
Medigap may save more if:
You frequently use healthcare, want broad provider access, travel around the United States or prefer paying higher predictable premiums in exchange for reducing certain Original Medicare cost-sharing.
The key mistake is comparing:
Medicare Advantage premium
against:
Medigap premium
and stopping there.
Instead compare:
Total yearly premiums + medical costs + drug costs + maximum financial exposure + provider access.
For many retirees, the “cheapest” Medicare option isn’t necessarily the plan with the smallest monthly premium.
It’s the option that provides the best balance between predictable costs, healthcare access and financial protection over the years ahead.
