High-Deductible Plan G

How Plan G Prices Are Set

Pricing Method How It Works
Community-rated Same price regardless of age
Issue-age-rated Based on your age when you buy
Attained-age-rated Rises as you get older

Plan G vs Plan F and Plan N

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 F also pays the Part B deductible but is only for people first eligible before January 1, 2020. Plan N costs less but adds copays and excess charges.

Medicare Plan G, Comparing Medicare Supplement Plan G to Other Medigap Plans

When to Buy

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.

Guaranteed issue: when your Medicare Advantage plan exits your area, you can generally purchase certain Medicare Supplement plans with no health questions asked, up until 63 days after that coverage ends.

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.

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.

All 10 Medigap Plans Compared

*Only people who became eligible for Medicare before January 1, 2020, can buy Plans C and F. **Plans K and L come with a yearly out-of-pocket limit that Medicare updates each year; once you hit it, the plan covers 100% of covered services for the remainder of the year. ***Plan N covers all Part B coinsurance apart from copays of up to $20 for certain office visits and up to $50 for ER visits that do not result in an inpatient admission. Massachusetts, Minnesota and Wisconsin use their own way of standardizing plans.

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.

After the Part B deductible, you pay little or nothing

✔

Plan N

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.

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

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.

Plan G covers every gap in Original Medicare except the Part B deductible, including the Part A deductible, hospital and skilled nursing coinsurance, Part B coinsurance and excess charges. It also covers 80% of foreign travel emergency care after a $250 deductible.

➤ What is the Part B deductible for 2027?

The 2026 Part B deductible is $283, and the Medicare Trustees project $292 for 2027. The official amount is announced in November. With Plan G, the Part B deductible is the main cost you pay yourself.

➤ What is the High-Deductible Plan G deductible for 2027?

The High-Deductible Plan G deductible is $3,050 for 2027, up from $2,950 in 2026, according to CMS. After you meet it, the plan pays like regular Plan G for the rest of the year, usually for a much lower premium.

➤ Is Plan G better than Plan F?

Plan G covers everything Plan F does except the Part B deductible. Plan F is only available to people first eligible for Medicare before January 1, 2020, so Plan G is the most complete plan for most new enrollees.

➤ Is Plan G the same with every insurer?

Yes. Plan G benefits are standardized, so every insurer’s Plan G covers the same things in your state. Prices, pricing methods and rate increases differ, so compare quotes for the same letter at your ZIP code.

➤ How are Plan G prices set?

Insurers use community rating, issue-age rating or attained-age rating. Community-rated plans charge the same regardless of age, issue-age plans are based on your age when you buy, and attained-age plans rise as you get older.

➤ Is Plan G or Plan N better?

Plan G has higher premiums but no copays and covers excess charges. Plan N costs less monthly, but you pay up to $20 for some office visits, up to $50 for some ER visits and any excess charges.

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

The best time is your six-month Medigap Open Enrollment Period, which starts the first month you are 65 or older and enrolled in Part B. During it, insurers cannot deny you or charge more for health conditions. Outside it, most states allow health questions unless you have a guaranteed issue right.

➤ Does a Medigap plan cover prescription drugs?

No. Medigap plans sold today do not include drug coverage, so pair your plan with a standalone Part D plan. For 2027, the Part D deductible can be up to $700, and the out-of-pocket cap on covered drugs is $2,400, according to CMS.
