What Original Medicare Leaves You to Pay

Original Medicare leaves gaps, and a Medicare Supplement plan is designed to fill them. It can pay these costs:

Original Medicare Gap What It Means for You Covered By
Part A deductible Applied each hospital benefit period instead of annually. The 2026 amount was $1,736. Plans B, C, D, F, G and N fully; K, L and M partially
Part A hospital coinsurance Daily charges after day 60 of a hospital stay, which climb after day 90 All 10 plans, plus 365 extra hospital days
Part B deductible An annual deductible owed before Part B pays. In 2026, $283. Only Plans C and F
Part B coinsurance Typically 20% of the approved amount, with no annual cap All plans (K and L in part, N with copays)
Part B excess charges As much as 15% over the approved amount from doctors who do not accept assignment Plans F and G
Skilled nursing coinsurance Daily charges for days 21 through 100 of a covered stay Plans C, D, F, G, M and N (K and L in part)
Emergency care abroad Care outside the U.S. is generally not covered by Original Medicare. Plans C, D, F, G, M and N, up to plan limits

No limit unless you add a supplement: Original Medicare does not have an out-of-pocket maximum. If you lack a Medigap plan or other coverage, the 20% you may owe on Part B services has no ceiling.

Massachusetts, Minnesota and Wisconsin use their own way of standardizing plans.

Plan G vs N vs HDG

Plan What You Pay Best For
Plan G The Part B deductible; once it’s met, Medicare-approved costs are covered Most complete coverage for new enrollees
Plan N Part B deductible, Part B excess charges, and copays of up to $20 for some office visits and up to $50 for some ER visits Lower premium, accepts small copays
High-Deductible Plan G A yearly deductible, then coverage like Plan G Healthy people who want the lowest premium

Plan letter determines Medigap benefits, which are standardized. Prices differ by insurer, age, ZIP code and tobacco use.

Plan G, Plan N and High-Deductible Plan G

Most people new to Medicare choose one of these three. Plan G covers every gap except the Part B deductible. Plan N trades a lower premium for copays of up to $20 for some office visits and up to $50 for ER visits that do not lead to admission, and it does not cover Part B excess charges. High-Deductible Plan G has a $3,050 deductible for 2027, up from $2,950, then covers like Plan G. See Plan G vs Plan N.

Plan G

✔

After the Part B deductible, you pay little or nothing

✔

Covers Part B excess charges

✔

Highest premium of the three

Plan N

✔

You pay the Part B deductible plus small copays

✔

Does not cover Part B excess charges

✔

Usually a lower premium than Plan G

High-Deductible G

✔

Before coverage begins, you pay up to $3,050 in 2027

✔

Then covers like Plan G

✔

Lowest premium

Why Plan G Remains a Top Choice for Seniors

How Medigap Prices Are Set

Your Age

Many insurers charge more as you get older.

Your ZIP Code

Prices vary by state and area.

Tobacco Use

Tobacco users usually pay more.

Discounts

Household or other discounts, which vary by insurer and state.

Pricing Method How the Premium Is Set Over Time
Community-rated All people in an area pay one premium, whatever their age Does not go up as you age, but may go up for inflation and other reasons
Issue-age-rated Based on your age when you buy Does not go up as you age, but may go up for other reasons
Attained-age-rated Based on your current age Rises as you age, on top of other increases

Which method applies depends on the insurer and the state. Before buying, find out how a policy is priced, not only what it costs now.

When You Can Buy

Key Takeaway

Your Medigap Open Enrollment Period lasts six months and begins the first month you are both 65 or older and enrolled in Part B. During this period, an insurer cannot turn you down or charge you more based on your health.

Be aware: once your six-month Medigap Open Enrollment Period has passed, and without a guaranteed issue right, insurers in most states may ask health questions and turn you down or charge you more.

In certain situations, federal law also grants guaranteed issue rights, generally within 63 days of other coverage ending:

You May Have a Right to Buy If

✔

Your Medicare Advantage plan exits your area or stops serving Medicare

✔

You enrolled in Medicare Advantage when you first became eligible at 65 and want to go back within the first year

✔

You left a Medigap policy to try Medicare Advantage for the first time and want to go back within a year

✔

Employer or union coverage that pays after Medicare stops

✔

Your Medigap insurer goes bankrupt or deceives you

Your state may give you extra rights: in New York and Connecticut you can enroll in Medigap at any time of year with no health questions, while states like California and Oregon offer an annual window to move to a plan that is equal or lesser.

What Medigap Does Not Cover

Not Covered by Medigap

✔

Prescription drugs: add a standalone Part D plan

✔

Routine dental care, hearing aids, and eye exams for glasses

✔

Long-term custodial care, whether in a nursing home or at home

✔

Private-duty nursing

In 2027, a standalone Part D plan can have a deductible of no more than $700 and an out-of-pocket cap of $2,400. Buy it with Medigap to avoid a late enrollment penalty that lasts for life.

Medigap vs Medicare Advantage

Medicare Advantage Original Medicare + Medigap
Monthly premium Often low or $0 (2027 average $12, CMS) Higher; varies by plan letter, age and ZIP
Doctors Usually a network Any provider in the U.S. that accepts Medicare
Costs when you get care Copays and coinsurance up to a yearly maximum Low and predictable; on Plan G, little or nothing once the Part B deductible is met
Drug coverage Usually included Add a separate Part D plan
Dental, vision, hearing Many plans may include some coverage Not included
Changing later Every year during Annual Enrollment Health questions in most states once your Medigap Open Enrollment Period ends

How to Buy

Step by Step

1

Choose your plan letter. Plan G, Plan N and High-Deductible Plan G are the ones most people compare.

2

Ask Aflac for a quote on that letter. Then get quotes for the same letter from other insurers.

3

Find out the pricing method and rate history. How a premium changes over the years matters as much as what you pay now.

4

Pick the right time to buy. If possible, purchase during a guaranteed issue window or your Medigap Open Enrollment Period.

5

Add a Part D plan. Medigap does not cover drugs.

For married couples: spouses each need their own policy, and some insurers give a household discount.

Turning 65 in 2027

When you turn 65 in 2027, you get a seven-month Initial Enrollment Period: the three months before your birthday month, the birthday month itself and the three months that follow. If you sign up in the first three months, coverage begins on the first day of your birthday month.

Turning 65 Checklist

✔

Enroll in Part A and Part B, unless you have qualifying employer coverage and decide to postpone Part B

✔

Choose between Medicare Advantage and Original Medicare plus Medigap

✔

Enroll in a drug plan, or a Medicare Advantage plan that includes drugs, to avoid a late Part D penalty

✔

If you go with Medigap, purchase during your six-month Medigap Open Enrollment Period

Help Paying Medicare Costs

When your income and savings are limited, two programs can greatly lower your Medicare costs:

Medicare Savings Programs

✔

Run by your state Medicaid office

✔

May cover your Part B premium, and in some cases deductibles and coinsurance

✔

Income and asset limits vary by state

Extra Help (Part D)

✔

Run by Social Security

✔

Lowers Part D premiums, deductibles and copays

✔

Those enrolled in a Medicare Savings Program qualify automatically

If you qualify for both Medicare and full Medicaid, you may also be able to join a Dual Special Needs Plan. See help for low-income Part D beneficiaries.

Plans K and L: Lower Premiums With a Cost Cap

Rather than paying all of most costs, Plans K and L pay a portion: Plan K covers 50% and Plan L covers 75% of most cost sharing, leaving the remainder to you. In return for their lower premiums, both carry an annual out-of-pocket limit set by Medicare each year. After you hit that limit, the plan covers 100% of covered services for the remainder of the year.

These plans may fit people who want catastrophic protection for a lower premium and can manage some costs along the way. Check whether your insurer sells Plan K or L in your state.

Plans C and F for Earlier Enrollees

Only Plans C and F cover the Part B deductible. Since January 1, 2020, they have not been sold to people newly eligible for Medicare. If you became eligible for Medicare before that date, even without enrolling, you may still be able to purchase Plan C or F, including a High-Deductible Plan F that has the same $3,050 deductible for 2027.

For most people eligible to buy either, set the yearly premium gap between Plan F and Plan G against the Part B deductible. If the extra cost of Plan F exceeds what it saves you on the deductible, Plan G is the better value.

Medigap Under 65

If disability or end-stage renal disease gives you Medicare before 65, federal law does not make insurers sell you a Medigap policy, though many states require it. Prices for those under 65 can run much higher, and plan options may be limited. At 65, you get a fresh six-month Medigap Open Enrollment Period, during which you can buy any plan sold in your state at the same prices others your age pay.

Medigap When You Travel

Within the U.S., a Medigap plan goes wherever you go, since it works with any provider that accepts Medicare. Abroad, Original Medicare generally pays nothing, but Plans C, D, F, G, M and N pay 80% of emergency care outside the U.S. after a $250 annual deductible, up to a $50,000 lifetime limit.

Rate Increases and Switching Insurers Later

Once you buy Medigap, its benefits never change, but its premiums can. Insurers submit rate increases to state regulators, frequently once a year. Since the same plan letter has the same benefits everywhere, moving to a cheaper insurer can cut costs while your coverage stays the same.

The drawback is underwriting. Outside your Medigap Open Enrollment Period or a guaranteed issue situation, most states allow the new insurer to ask health questions and turn you down. Do not cancel your current policy until the new one has been approved and is in force.

How Medigap Claims Work

Usually you won’t ever file a Medigap claim. Your doctor sends the bill to Medicare, Medicare pays its portion, and the claim passes automatically to your Medigap insurer, which then pays its portion. A Medicare Summary Notice and an explanation of benefits show you what each one paid.

Medigap and Part D Together

Medigap plans sold now don’t include prescription coverage, so you should add a Part D plan as well. It doesn’t need to come from your Medigap insurer. Pick it based on your drugs and pharmacy in Medicare Plan Finder and look it over each fall. If you put off drug coverage with no other creditable coverage, the late penalty adds 1% of the national base beneficiary premium, $41.33 for 2027, for each month you were without it.

Excess Charges and Medicare Assignment

When a doctor “accepts assignment,” they agree to accept Medicare’s approved amount as payment in full. Doctors who don’t accept assignment may charge as much as 15% more, known as a Part B excess charge. Excess charges are covered by Plans F and G; Plan N and most other plans do not cover them.

Because most doctors accept assignment and some states restrict or ban excess charges, the risk is small for many people. Before deciding whether to pay for excess charge coverage, ask your doctors if they accept assignment.

Your Medigap Open Enrollment Period in Detail

You get a six-month Medigap Open Enrollment Period beginning in the first month you are both 65 or older and enrolled in Part B. It occurs only once and can’t be restarted. During this period, insurers have to sell you any Medigap plan they offer in your state at the same price healthy people pay.

If you work past 65, keep employer coverage and postpone Part B, your Medigap Open Enrollment Period does not begin until you sign up for Part B. Signing up for Part B early when you do not need it starts the clock and can waste this protection.

Frequently Asked Questions

➤ Does Aflac sell Plan G?

Yes, in states where its Medigap plans are approved. Availability varies by state, so check whether Aflac offers Plan G at your ZIP code before comparing its quote with those from other insurers selling the same standardized plan.

➤ Is Aflac Plan G the same as other Plan G?

Yes. Plan G benefits are standardized, so Aflac’s Plan G covers the same things as Plan G from any other insurer in most states. The differences are price, pricing method, rate increase history and customer service, which makes comparing quotes the key step.

➤ When is the best time to buy a Medigap plan?

The best time is your six-month Medigap Open Enrollment Period, starting the first month you are 65 or older and enrolled in Part B. During that window an insurer cannot deny you or charge more because of health conditions, while outside it most states allow health questions.

➤ Do Medigap plans cover prescription drugs?

No. Medigap plans, including Plan G, do not cover prescription drugs, so you need to pair your policy with a separate Part D plan. For 2027 the maximum Part D deductible is $700 and the out-of-pocket cap is $2,400.

➤ What does Aflac Plan G not cover?

Plan G does not cover the Part B deductible, which is $283 in 2026 and projected at $292 for 2027. Like other Medigap plans, it also does not cover routine dental, routine vision, hearing aids or prescription drugs, so plan for those costs separately.

➤ Is there a high-deductible version of Plan G?

Yes. High-Deductible Plan G is a standardized option with a 2027 deductible of $3,050, up from $2,950 in 2026. Whether Aflac sells it in your state varies, so ask for a quote on both the standard and high-deductible versions.

➤ How is Aflac Plan G priced?

It depends on the state. Medigap insurers use community-rated, issue-age-rated or attained-age-rated pricing, and the method affects how premiums change as you age, so ask Aflac which method applies where you live and compare quotes for your ZIP code.

➤ Does Aflac Plan G cover travel outside the U.S.?

Yes, for emergencies. Plan G pays 80% of emergency care abroad after a $250 deductible, up to a $50,000 lifetime limit. This is the standard Medigap foreign travel emergency benefit, and routine care outside the country is not covered.
