Standard Plan G and high-deductible Plan G are the same Medigap plan. They cover the same benefits, pay the same claims, and come from the same insurers. The only difference is timing: with standard Plan G, the policy starts paying almost immediately; with the high-deductible version, you pay up to $3,050 of Medicare-covered costs yourself in 2027 before the policy pays anything.

That single difference makes the choice a maths problem, not a loyalty test. The high-deductible version charges a much lower monthly premium, so in a healthy year it wins by a wide margin. In a year with a hospital stay or a run of specialist visits, the standard plan can win instead. The right question is not “which plan is better?” but “how much care do I expect to use, and where is my break-even point?”

This guide runs that maths with real, labelled figures, explains what counts toward the $3,050 deductible, and flags the one trap that catches people who choose the cheaper premium first and want to switch later. If you are still deciding whether Medigap is right for you at all, start with our hub guide, Medigap explained, which covers what Medigap pays, what it leaves out, and why it requires Original Medicare Part A and Part B.

The short answer

High-deductible Plan G saves you money when your annual Medicare cost-sharing stays below your break-even point, and standard Plan G saves you money when it goes above it. Using illustrative 2026 Los Angeles figures from the California Department of Insurance — a standard Plan G premium of $2,245 a year against $525 for the high-deductible version — the break-even point sits at roughly $2,000 of Medicare cost-sharing in the year. Below that, the high-deductible version wins; above it, standard Plan G wins. Your own break-even point depends on the two premiums quoted for you, so run the same sum with your own quotes before deciding. Both versions cover the same benefits once the deductible is met, including Part B excess charges, and both leave you paying the annual Part B deductible yourself.

Same plan, different deductible

Medigap plans are standardized by federal law: the same lettered plan carries the same core benefits regardless of which insurer sells it. Plan G is the most comprehensive Medigap plan available to people new to Medicare, and the high-deductible version is Plan G with one rule attached. That is the whole difference, and it is worth stating plainly because the two policies are often sold as if they were different kinds of cover. They are not.

The comparison with Plan N is a different trade-off — lower premiums in exchange for copays and no excess-charge cover — and we cover it in full in Medigap Plan G vs Plan N: which is better for you in 2027? If you are choosing between G and N rather than between two versions of G, read that guide instead.

How the $3,050 deductible actually works

The Centers for Medicare & Medicaid Services (CMS) sets the high-deductible amount each year. For 2027 it is $3,050, up from $2,950 in 2026 — a $100 rise that follows a 3.40% increase in the Consumer Price Index for All Urban Consumers (CPI-U). CMS announced the 2027 amount in October 2026, and it applies to the high-deductible versions of Plans F, G and J alike. We covered the announcement in detail in Medigap 2027 changes: high-deductible Plan G rises to $3,050.

Here is what that $3,050 means in practice:

  • It is an annual out-of-pocket amount, excluding premiums. CMS describes it as the annual out-of-pocket expenses, excluding premiums, that you must pay before the policy begins paying benefits. Your monthly premiums do not count toward it.
  • It counts Medicare-covered costs. The costs that count are the deductibles, coinsurance and copayments Medicare leaves you with — the Part A hospital deductible, the 20% Part B coinsurance, skilled nursing facility coinsurance, and similar charges.
  • The Part B deductible counts toward it. This is the detail people most often miss. Plan G never pays the Part B deductible — that is the one gap it leaves open — but the amount you pay toward that deductible counts toward the $3,050. In 2026 the Part B deductible is $283, so $283 of the high deductible is already used up once you have paid it.
  • Once you hit $3,050, the policy pays like standard Plan G. For the rest of the calendar year, the high-deductible version pays 100% of covered costs, exactly as standard Plan G does. There is no second deductible and no coinsurance after that point.
  • It resets every January 1. The count starts again each calendar year. A December hospital stay and a January follow-up fall in different deductible years.

One more point worth knowing: the high-deductible amount is the same in every state. CMS sets one national figure, so the $3,050 applies whether you live in Florida, Ohio or California. What varies by state and insurer is the premium — and that variation is exactly what decides whether the high-deductible version is worth it for you.

The break-even maths: three worked examples

Premiums vary so widely by insurer, age, ZIP code and pricing method that no national “typical premium” is worth quoting as fact. So instead of inventing one, this section uses real published figures as an illustrative example — and labels them as such, so you can repeat the same sum with your own quotes.

The example uses the California Department of Insurance’s 2026 Medicare supplement rate guide for Los Angeles, for a 65-year-old non-tobacco user: standard Plan G from $2,245 a year and high-deductible Plan G from $525 a year. These are the lowest prices listed for each version in that guide, from different insurers, so treat them as an illustration of the maths rather than a quote you can buy. Your own figures will differ — but the method is the same everywhere.

Step 1: work out the premium saving. $2,245 − $525 = $1,720 a year saved by choosing the high-deductible version.

Step 2: work out the extra cost-sharing you could face. With standard Plan G you pay only the Part B deductible, $283 in 2026. With the high-deductible version you can pay up to $2,950 in 2026 (the 2026 deductible). The most extra cost-sharing you can face is $2,950 − $283 = $2,667.

Step 3: find the break-even point. You come out ahead on the high-deductible version whenever your extra cost-sharing is less than your premium saving — that is, whenever your total Medicare cost-sharing for the year is below $283 + $1,720 = $2,003. Above $2,003, standard Plan G wins.

Here is what that looks like in three plausible years:

YearYour Medicare cost-sharingStandard Plan G totalHigh-deductible Plan G totalWinner
A healthy year: a few doctor visits, no hospital stay$300$2,245 + $283 = $2,528$525 + $300 = $825High-deductible, saves $1,703
An average year: tests, a specialist, a short procedure$1,500$2,528$525 + $1,500 = $2,025High-deductible, saves $503
A bad year: hospital stay, surgery, rehab$2,950 (deductible met)$2,528$525 + $2,950 = $3,475Standard, saves $947

Two things stand out. First, the high-deductible version wins in the first two scenarios by a wide margin — and most years look like the first two. Second, even in the worst case, the most you can lose by choosing it is bounded: in this example, $947 in a year where you hit the full deductible. That is the real shape of the decision — a likely saving of hundreds or thousands against a capped worst-case loss of under $1,000.

Run the same three steps with the two quotes you actually receive. If the premium gap in your area is small — say $600 a year — your break-even point drops to about $883 of cost-sharing, and standard Plan G becomes the better bet for far more people. If the gap is large, the high-deductible version wins for almost everyone except the heaviest users of care.

How 2027 changes the maths

Two 2027 figures matter here, and they are in different states of readiness:

  • The high-deductible amount is final: $3,050. CMS published it in October 2026, so you can plan on it. It is $100 higher than 2026, which moves the break-even point up by roughly $100 — a small shift, not a reason to change your answer.
  • The 2027 Part B deductible is not yet announced. CMS had not published the 2027 Part B premium or deductible as of early November 2026; the Trustees Report projects a premium of about $209.50 a month, but that is a projection, not a final figure. The worked examples above therefore use the confirmed 2026 Part B deductible of $283. When CMS announces the 2027 figure, the break-even sum moves by the same amount — if the deductible rises, both versions cost a little more, and the high-deductible version’s break-even point rises with it.

One more 2027 point: the Part D out-of-pocket cap rises to $2,400 and the Part D deductible to $700, both already final. That matters because Medigap does not cover prescription drugs — you need a separate Part D plan — and drug costs sit outside the maths in this article entirely. If you have not checked your Part D plan for 2027, read Medicare Part D premiums could jump 50% in 2027 if you keep the same plan before December 7.

Who the high-deductible version suits — and who should stay standard

The maths points in a clear direction, but the decision is not only maths. These are the patterns that tend to fit each version:

High-deductible Plan G usually fits if you:

  • Are in good health and use little care beyond preventive visits and routine check-ups — the scenario where the premium saving is nearly pure profit.
  • Have savings you could comfortably use to cover up to $3,050 in a bad year without stress. The worst case is capped, but only if you can actually pay it.
  • Are comfortable with a larger bill in a bad year in exchange for a much smaller bill in most years, and you will not lose sleep over the uncertainty.
  • Are buying at 65, when premiums are at their lowest and the gap between the two versions is usually at its widest.

Standard Plan G usually fits if you:

  • Already see specialists regularly, manage a chronic condition, or expect a procedure, surgery or hospital stay in the coming year. Your cost-sharing is likely to pass the break-even point.
  • Want predictable costs above all else. Standard Plan G means your only real medical bill each year is the Part B deductible plus your premium — there are no surprise cost-sharing bills.
  • Would struggle to pay up to $3,050 out of pocket in a bad year. A plan that only saves money when you stay healthy is a poor fit if a bad year would cause real financial strain.
  • Value the simplicity of never thinking about deductibles, coinsurance or bills after the Part B deductible is met.

Neither choice is a mistake in itself. The mistake is choosing on premium alone without running the break-even sum, or choosing the high-deductible version without a plan for the $3,050.

The switching trap: choosing cheap now can cost later

This is the part of the decision that deserves the most attention, because it is the one you cannot undo cheaply.

Medigap’s one-time 6-month open enrollment window — the period beginning the first day of the month you are both 65 or older and enrolled in Part B — is the only time insurers must sell you any policy they offer without asking about your health. Outside that window, and without a guaranteed-issue right, insurers in most states may use medical underwriting when you apply to switch plans: they can review your health history, decline you, charge you more, or impose a waiting period for pre-existing conditions.

That means if you choose high-deductible Plan G at 65, stay healthy for a few years, then develop a condition and want the certainty of standard Plan G, you may not be able to switch — or you may be charged far more than the standard premium you would have paid all along. Some states soften this with birthday or anniversary rules that let you switch without underwriting each year, but most do not.

Before you choose, read when can you switch Medigap plans without underwriting? It explains the three doors that let you switch, the state rules, and why December 7 is a different deadline — the annual Medicare Open Enrollment period that ends December 7 governs Medicare Advantage and Part D changes, not Medigap switching. Confusing the two windows is one of the most common Medigap mistakes, and it is an expensive one: missing your 6-month window does not get fixed by waiting for December.

If you are inside your 6-month window right now, you have the most freedom you will ever have. Use it to choose the version you can live with for years, not just the cheapest premium this year.

How to compare quotes in your ZIP code

  1. Get both quotes from the same insurers. Ask each insurer for standard Plan G and high-deductible Plan G at your age and ZIP code, so the premium gap is real and comparable. Comparing one insurer’s standard G with another’s high-deductible G mixes two variables at once.
  2. Run the three-step break-even sum. Premium saving, minus the Part B deductible, is your break-even point. Compare it honestly with what you spent on Medicare cost-sharing in the last two or three years.
  3. Check the pricing method. Insurers price Medigap by attained age, issue age or community rating, and the method affects how premiums rise as you get older. Ask how the premium has changed over the past five years for each version.
  4. Ask your state’s SHIP program. Your State Health Insurance Assistance Program gives free, unbiased help comparing Medigap quotes in your area, and it has no policy to sell you. Find yours through Medicare.gov or your state insurance department.
  5. Check the insurer, not just the price. The benefits are standardized, so the cheapest quote is not automatically the best buy — claims service and financial strength matter, and they are the things you cannot see in a premium table.
  6. Decide before your 6-month window closes. If you are in that window, the decision you make now is the one you can make without health questions. Do the comparison properly, then choose — and keep a note of the quotes and the break-even point you calculated, so you can revisit the decision next year with real numbers.

Frequently asked questions

What is the high-deductible Plan G deductible for 2027?

The high-deductible amount for Medigap Plans F, G and J in 2027 is $3,050, set by the Centers for Medicare & Medicaid Services in October 2026. It is the annual out-of-pocket amount, excluding premiums, that you pay in Medicare-covered costs before the policy begins paying benefits. In 2026 the amount is $2,950, so the 2027 figure is a $100 increase driven by a 3.40% rise in the Consumer Price Index for All Urban Consumers.

Is high-deductible Plan G available to me?

High-deductible Plan G is available to people who are new to Medicare on or after January 1, 2020, according to CMS. You also need to be enrolled in Original Medicare Part A and Part B, as with any Medigap policy, and you cannot buy a Medigap policy while you are enrolled in a Medicare Advantage plan. If you became eligible for Medicare before 2020, high-deductible Plan F may be the equivalent option open to you, subject to the same $3,050 deductible in 2027.

Does the Part B deductible count toward the $3,050?

Yes, the Part B deductible you pay counts toward the high-deductible amount, even though Plan G itself never pays any part of the Part B deductible. In 2026 the Part B deductible is $283, so paying it uses up $283 of the high deductible. The same applies to other Medicare-covered costs you pay, including the Part A hospital deductible and 20% Part B coinsurance. CMS describes the $3,050 as annual out-of-pocket expenses, excluding premiums, that you must pay before the policy begins paying benefits.

Which is better if I am healthy — standard Plan G or high-deductible Plan G?

If you are healthy and use little care, high-deductible Plan G usually costs less over the year, because the premium saving is larger than the small amount of cost-sharing you pay. In the illustrative example in this guide, a healthy year with $300 of cost-sharing cost $825 in total with the high-deductible version against $2,528 with standard Plan G. The trade-off is that a bad year can cost more, so the choice also depends on whether you have savings to cover up to $3,050 and whether you could switch later, which may require underwriting.

Can I switch from high-deductible Plan G to standard Plan G later?

You can apply to switch at any time, but outside your one-time 6-month Medigap Open Enrollment Period — and without a federal guaranteed-issue right or a state switching rule — insurers in most states may use medical underwriting, which means they can decline your application or charge you more because of your health. A few states have birthday or anniversary rules that allow switching without underwriting. Check your state’s rules and read our guide to switching without underwriting before you assume a later switch will be available.

Does high-deductible Plan G cover Part B excess charges?

Yes, once you have met the $3,050 deductible, high-deductible Plan G covers Part B excess charges in full, exactly as standard Plan G does. Excess charges are the amounts some doctors who do not accept Medicare assignment may charge above the Medicare-approved amount, up to 15% more. This is one of the features that separates Plan G from Plan N, which does not cover excess charges at all, and it applies to both versions of Plan G after the deductible is met.
