High-Deductible Plan G Cost

Reviewed by Russell Noga, Licensed Medicare Insurance Broker (all 50 states) — Last updated October 8, 2026

High-Deductible Plan G usually has a much lower premium than regular Plan G, but you pay up to $3,050 in covered costs in 2027 before it pays.

Your worst-case yearly cost on HDG is the premium plus $3,050. Compare that with regular Plan G’s premium plus the Part B deductible.

When to Buy

Watch for: outside your six-month Medigap Open Enrollment Period or a guaranteed issue right, most states let insurers ask health questions and decline you or charge more.

Guaranteed issue: if your Medicare Advantage plan leaves your area, you generally can buy certain Medicare Supplement plans without health questions, until 63 days after your coverage ends.

Help Paying Medicare Costs

If your income and savings are limited, two programs can cut your Medicare costs sharply:

Medicare Savings Programs

✔

Run by your state Medicaid office

✔

Can pay your Part B premium, and sometimes 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

✔

People in a Medicare Savings Program qualify automatically

Those who are eligible for Medicare along with full Medicaid might also have the option of enrolling in a Dual Special Needs Plan. Learn more about help for low-income Part D beneficiaries.

What Original Medicare Leaves You to Pay

A Medicare Supplement plan is built to cover the gaps in Original Medicare. These are the costs it can pick up:

Original Medicare Gap What It Means for You Covered By
Part A deductible A deductible for each hospital benefit period, not once a year. It was $1,736 in 2026. Plans B, C, D, F, G and N in full; K, L and M in part
Part A hospital coinsurance Daily charges after day 60 of a hospital stay, rising after day 90 All 10 plans, plus 365 extra hospital days
Part B deductible A yearly deductible before Part B pays. It was $283 in 2026. Only Plans C and F
Part B coinsurance Usually 20% of the approved amount, with no yearly cap All plans (K and L in part, N with copays)
Part B excess charges Up to 15% above the approved amount from doctors who do not take assignment Plans F and G
Skilled nursing coinsurance Daily charges from day 21 to day 100 of a covered stay Plans C, D, F, G, M and N (K and L in part)
Emergency care abroad Original Medicare generally does not cover care outside the U.S. Plans C, D, F, G, M and N, up to plan limits

No cap without a supplement: Original Medicare has no out-of-pocket maximum. Without a Medigap plan or other coverage, there is no limit to the 20% you can owe on Part B services.

Frequently Asked Questions

➤ What is the HDG deductible for 2027?

The High-Deductible Plan G deductible for 2027 is $3,050, up from $2,950 in 2026. You pay covered Medicare costs up to that amount first, and then the plan covers the rest the same way standard Plan G does.

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

Aim for 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 decline your High-Deductible Plan G application or raise your price because of health conditions.

➤ Do Medigap plans cover prescription drugs?

No, High-Deductible Plan G does not cover prescriptions. Pair it with a standalone Part D plan, where the 2027 deductible can reach $700 and out-of-pocket drug costs are capped at $2,400 for the year. Skipping Part D when first eligible can also lead to a late enrollment penalty later on.

➤ How much can High-Deductible Plan G save compared with Plan G?

HDG premiums are typically lower than standard Plan G, but the savings vary by insurer, age and ZIP code. Get quotes for both and compare the yearly premium difference with the $3,050 deductible you might pay in a bad year.

➤ What is the worst-case yearly cost of High-Deductible Plan G?

Your worst case is roughly the annual premium plus the $3,050 deductible for 2027. Once you reach the deductible, the plan pays like standard Plan G, so your remaining covered Medicare costs are generally paid.

➤ Who is High-Deductible Plan G a good fit for?

It often suits people in good health who rarely use medical care and want lower monthly premiums. Those who expect frequent care, or prefer predictable bills, may find standard Plan G more comfortable. Setting aside savings to cover the deductible can make this approach far less stressful.

➤ Does the Part B deductible count toward the HDG deductible?

Yes, the Part B deductible counts toward the High-Deductible Plan G deductible. Out-of-pocket costs for services the plan would cover add up toward the $3,050 annual threshold in 2027. Premiums you pay for the policy itself do not count toward that deductible.

➤ Can I switch from High-Deductible Plan G to regular Plan G later?

You can apply, but outside open enrollment or a guaranteed issue right, insurers in most states may ask health questions and can decline you. Check your state’s rules before planning a future switch. Because approval is not guaranteed later, choose the deductible level you can live with long term.

➤ Is there a High-Deductible Plan F too?

Yes, but High-Deductible Plan F is only for people first eligible for Medicare before January 1, 2020. It shares the same $3,050 deductible for 2027, while everyone else who wants a high-deductible option looks at HDG.
