High Deductible Medicare Supplement Plan G

For years, High Deductible Plan G was a niche recommendation, something I mentioned almost as an afterthought.

Today it's one of the first plans I bring up with healthy Medicare beneficiaries.

That shift didn't happen because the plan changed. It happened because the market around it did — more on that below.

High Deductible Plan G pays for the exact same things as standard Plan G, just not until you've paid the annual deductible yourself first.

Instead of a higher premium to avoid nearly all Medicare-approved out-of-pocket costs, you pay a much lower premium.

In exchange, you accept the possibility of covering up to $2,950 (the 2026 deductible) in a year you need more care.

Quick Answer

If you're generally healthy and have $2,950 you could access without stress, High Deductible Plan G is one of the better values in Medicare Supplement insurance.

That's especially true if you'd rather keep an extra $100–$150 a month in your pocket than pay for coverage you may not need.

If a surprise bill like that would genuinely worry you, standard Plan G is probably worth the higher premium.

There's no wrong answer here — just a better fit for your situation.

Why My Advice About This Plan Has Changed

Five or six years ago, I rarely recommended High Deductible Plan G.

The premium gap between it and standard Plan G just wasn't large enough to justify taking on a $2,950 deductible.

Paying a bit more each month for the predictability of standard Plan G made sense for most people.

That's changed.

Medigap carriers raised Plan G and Plan N premiums throughout 2025 and into 2026.

High Deductible Plan G stayed one of the few options that kept its lower pricing intact.

Today it's common to see High Deductible Plan G priced around $50–$70 a month, while standard Plan G runs $170–$220 a month.

The exact numbers depend on your state and carrier.

That changes the math.

Instead of asking "is the deductible too high?" I tell clients to compare the annual Plan G premium against the annual HDG premium plus the full deductible.

Those two numbers are often closer than people expect — sometimes even in a genuinely bad medical year.

Standard Plan GHigh Deductible Plan G
Monthly premium$195$60
Annual premium$2,340$720
Max deductible exposure$2,950
Worst-case annual total$2,340$3,670

Even in the worst possible year — the full deductible, met completely — High Deductible Plan G comes out around $1,330 more than standard Plan G that year.

Most years look nothing like the worst case.

The real question isn't "could this cost more?" It's "how many years in a row do I expect to have my worst medical year?"

If you want to run your own numbers, our Medigap cost calculator can help you compare premiums side by side.

It isn't only about the math, either.

A lot of my clients are on a fixed income, and a $150-a-month difference matters to them even when they're perfectly comfortable with the coverage trade-off.

Keeping catastrophic protection while lowering the guaranteed monthly bill is the appeal.

The old thinking was that High Deductible Plan G only made sense for people in excellent health. I think that's an outdated way of looking at it now.

One of the bigger frustrations I have with the Medicare Supplement market is how few deductible options actually exist.

In the under-65 insurance world, you can typically choose from a range of deductibles, and your premium adjusts accordingly.

A higher deductible buys you a lower premium, and you pick the level that fits you.

Medicare Supplement doesn't work that way. Right now it's really just standard Plan G or the one High Deductible option — nothing in between.

I'd genuinely like to see deductible tiers below $2,950 too, so people have more ways to trade a bit of premium for a bit of shared cost, instead of an all-or-nothing jump.

One question I get often: "Will High Deductible Plan G's premium climb just as fast as Plan G's?"

Historically, it's tended to rise more slowly, since carriers take on less claims risk when policyholders share more of the routine cost.

That said, no Medigap premium is guaranteed to stay low.

Rate increases depend on your carrier, your state, and whether your plan uses attained-age or issue-age pricing — future increases are never certain on any plan.

What I Think Is Happening Industry-Wide

Carriers are leaning harder into plans where beneficiaries share more of the upfront cost.

When policyholders cover more of the small, routine claims themselves, insurers pay out less overall, which tends to keep premiums lower over time than first-dollar coverage.

I think we're entering a new era in Medicare Supplement.

Taking on more shared cost, the way High Deductible Plan G does, gives people real relief on the monthly premium side that the market hasn't offered much of before.

I don't expect standard Plan G to go away, but I do think High Deductible Plan G is a much more attractive option than it was just a few years ago.

How High Deductible Plan G Actually Works

High Deductible Plan G pays for the exact same things as standard Plan G — Part A and B coinsurance, copays, and Part B excess charges.

The difference is that it doesn't pay them until you've paid the annual deductible yourself first.

For 2026, that deductible is $2,950.

Once you've paid that amount toward Medicare-covered cost-sharing, the plan switches on and pays exactly like standard Plan G for the rest of the year.

What You Still Get Before You Reach the Deductible

  • Original Medicare still pays its share
  • Preventive services covered by Medicare remain covered
  • Your deductible accumulates gradually throughout the year
  • You're never responsible for the entire bill — only Medicare's share until the deductible is met

The deductible doesn't mean you're uninsured. It simply changes who pays Medicare's portion until you've reached the annual limit.

What Actually Counts Toward the Deductible

Counts

  • Part A deductible
  • Part B coinsurance
  • Part B excess charges
  • Skilled nursing coinsurance

Doesn't Count

  • Dental and vision costs
  • Prescription drug costs
  • Services Original Medicare doesn't cover

How the Deductible Actually Accumulates

People often picture the deductible as one lump bill. In reality, it builds up gradually as claims come in over the year. Here's what that can look like:

  • January: Primary care visit — a small amount applied
  • March: MRI — more added toward the deductible
  • June: Outpatient surgery — deductible is now mostly met
  • September: Hospital stay — deductible is fully met
  • From that point forward, High Deductible Plan G pays like standard Plan G for the rest of the year

Who This Plan Is Really For

Reaching the deductible isn't inevitable.

It depends entirely on how much care you actually use in a given year.

One thing I've noticed over the years: I've had far more clients tell me they wish they'd looked at High Deductible Plan G sooner than clients tell me they regretted choosing it.

Usually a Good Fit

  • Generally healthy, mostly annual check-ups and routine care
  • Has $2,950 set aside they could use without financial stress
  • Would rather keep $100+ a month than pay for coverage they may not use

Usually a Better Fit for Plan G

  • Managing multiple chronic conditions with frequent visits
  • A surprise bill of a few thousand dollars would cause real stress
  • Tight monthly budget with little to no emergency savings

Why Some People Love HDG — and Others Don't

One thing I've learned after more than 15 years of helping people through this decision: choosing a Medicare Supplement plan isn't only about the numbers.

It's also about what actually lets you sleep at night.

I have clients who love High Deductible Plan G.

They enjoy keeping $100 or more a month, they understand exactly how the deductible works, and they're fine paying more out of pocket in an occasional heavier year.

I also have plenty of clients who choose standard Plan G, even after we've walked through the math together.

Some simply don't want to think about deductibles, track medical bills, or deal with claims paperwork.

They'd rather pay a higher monthly premium and know that once Medicare approves a service, they're done worrying about it.

That's a completely reasonable trade to make.

Neither choice is wrong. One isn't smarter than the other.

They're just different ways of managing the same risk.

The Point of This Guide

My goal isn't to talk everyone into High Deductible Plan G.

It's to make sure people actually understand it before deciding against it.

Plenty of people dismiss it because they believe they have no coverage until they've spent $2,950 out of pocket.

That's not how it works — Original Medicare pays its share from the very first covered service.

Once that clicks, some clients still choose standard Plan G because they value simplicity and predictable costs.

Others realize High Deductible Plan G offers better value than they thought and decide the savings are worth a limited amount of added risk.

Both are good decisions, because they're informed ones.

How Often Do People Reach the Deductible?

One of the biggest misconceptions about High Deductible Plan G is that you'll probably pay the full deductible every year.

That's not how Medicare spending actually works for most people.

MedPAC's data consistently shows that Medicare spending is heavily concentrated among a small share of beneficiaries.

In recent years, the costliest 5% of beneficiaries have accounted for well over 40% of all Medicare fee-for-service spending, while the least costly half of beneficiaries account for only about 4%.

That's a wide gap.

It means a small share of beneficiaries in an expensive medical year drive most of the spending, while the majority use routine, low-cost care most years.

In practical terms, most people don't generate enough Medicare cost-sharing in a typical year to come close to the deductible.

It mainly comes into play in years with a hospitalization, surgery, cancer treatment, or another major medical event.

Think of It Like Insurance

You're not buying High Deductible Plan G because you expect to hit the deductible every year.

You're buying it because it limits your financial risk in the years you do.

If you stay relatively healthy, you keep the premium savings.

If you have a major medical year, you may pay the deductible — but once it's met, the plan works just like standard Plan G for the rest of the year.

Instead of guessing, here's what three different levels of healthcare use typically look like on HDG, including the premium.

Low use
~$1,000/yr
Total
Moderate use
~$1,260/yr
Total
High use
~$3,300/yr
Total
ScenarioWhat It Looks LikeEst. Annual Total (Premium + Costs)
Low useAnnual physical, maybe one minor visit~$1,000
Moderate useMonthly primary care, quarterly specialist, routine labs~$1,260
High useChronic conditions, a hospital stay, frequent specialist care~$3,300 (deductible met)

The moderate-use client still comes out ahead of a standard Plan G premium alone.

Even the high-use client — someone managing diabetes and heart disease — landed only a few hundred dollars above what standard Plan G would have cost.

That was in a year that included a hospital stay.

The gap narrows in a bad year, but it rarely flips dramatically against you.

What Specific Claims Actually Look Like

It also helps to see how individual claims interact with the deductible, not just annual totals.

EventBefore Deductible Is MetAfter Deductible Is Met
Routine colonoscopyYou owe the Medicare coinsurance amountHDG pays it, just like standard Plan G
Knee replacementYou owe Medicare's coinsurance for the surgery and facility feesHDG picks up the coinsurance from that point on
Five-day hospital stayYou owe the applicable Part A coinsuranceHDG covers it like standard Plan G would
Cancer treatmentYou owe coinsurance as treatment continuesHDG covers your share for the rest of the year

In every case, Original Medicare is paying its share the entire time.

The deductible only determines how long you're covering the remaining coinsurance yourself before High Deductible Plan G takes over.

Common Misconceptions

Imagine you need a $100,000 surgery next month.

A lot of people assume they're on the hook for the whole bill because they haven't met the deductible yet.

That's not what happens.

Original Medicare pays its share immediately, exactly like it does for every Medicare beneficiary — that part never changes.

The only thing High Deductible Plan G affects is who covers the remaining Medicare cost-sharing — the coinsurance, copays, and excess charges — until you've reached $2,950.

Before that point, you're responsible for that portion. You're never uninsured.

I tell clients to think of it this way: for roughly $600–$800 a year in premium, you're putting a $2,950 ceiling on what Original Medicare could otherwise leave you owing.

Once it clicks that way, the plan tends to make a lot more sense.

Myth: I have no coverage until I hit $2,950. Reality: Original Medicare pays its share from day one — the deductible only affects who covers your remaining cost-sharing.
Myth: The deductible is one large bill all at once. Reality: It accumulates gradually as Medicare-covered expenses come in through the year.
Myth: Only perfectly healthy people should consider HDG. Reality: Your finances and comfort with risk matter just as much as your health history.

Why Someone Might Choose HDG Over Medicare Advantage

A lot of shoppers are really deciding between High Deductible Plan G and a Medicare Advantage plan.

Both advertise a lower monthly cost than standard Plan G.

They work very differently, though.

High Deductible Plan G pairs with Original Medicare, so you can see any provider nationwide who accepts Medicare, with no network to worry about and no referrals needed.

Medicare Advantage plans typically use a network, may require referrals or prior authorization, and can limit your options if you travel or split time between states.

High Deductible Plan G's benefits are also standardized by law, so coverage works the same regardless of which insurer you choose.

Medicare Advantage benefits and cost-sharing vary plan to plan and can change from year to year.

Neither is universally better.

If nationwide access and provider flexibility matter most to you, High Deductible Plan G is usually the stronger fit.

If a $0 premium and extra benefits like dental or vision matter more, Medicare Advantage may be worth a closer look.

Five Questions I Ask Every Client

1Could you pay the deductible tomorrow without stress?

Not because I expect you to — I want to know whether a bad medical year would create real financial pressure.

2How often do you actually use healthcare?

Some retirees see one doctor a year. Others see six specialists a month. Same age, very different recommendation.

3Are you buying peace of mind, or saving money?

That's really the heart of the HDG vs. Plan G decision.

4Would an extra $120 a month bother you more than an occasional bill?

Some people hate fixed costs. Others hate surprises. Your answer usually tells me which plan fits.

5Are you okay if switching later requires underwriting?

This one gets overlooked — more on it below.

The Biggest Mistakes I See

These are the ones specific to High Deductible Plan G.

For a broader list, see our guide to Medigap shopping mistakes to avoid.

Comparing monthly premiums instead of annual costs. A $100/month difference is $1,200 a year — that's most of the deductible right there.
Assuming you can switch back to Plan G anytime. Outside your initial enrollment window, most insurers require medical underwriting.
Thinking the deductible is due all at once. It accrues gradually as Medicare-covered expenses come in over the year.
Choosing HDG purely because it's cheapest. It's a good value for the right person — not automatically the right choice for everyone.

Best High Deductible Plan G Companies

Benefits are standardized across every insurer offering HDG, so the deciding factor is really who's most competitive in your area.

We've had good experience with both Cigna and Mutual of Omaha — both financially strong with a long history in the Medigap market.

For a fuller rundown, see our review of the best Plan G companies.

Can You Switch to Standard Plan G Later?

Yes, but it isn't guaranteed.

During your initial enrollment period, you have guaranteed-issue rights.

That means you can buy any Medigap policy without underwriting.

After that window closes, most insurers require medical underwriting to switch.

Clients in good health are often approved. Clients who've developed a chronic condition since enrolling may be denied or charged more.

A Pattern I've Noticed

I expected more clients to eventually switch back to standard Plan G. Very few actually do.

The ones who are happiest with HDG years later are almost always the ones who understood the trade-off going in — not the ones who treated it as a temporary discount.

My Advice After 15+ Years

The clients happiest with High Deductible Plan G years later aren't necessarily the healthiest ones.

They're the ones who understood the trade-off before they enrolled.

If you're generally healthy, financially comfortable covering the deductible, and would rather keep $1,000–$1,500 a year in your pocket, I think HDG deserves serious consideration.

If a rough medical year and a few thousand dollars in out-of-pocket costs would genuinely stress you out, I'd steer you toward standard Plan G instead.

It costs more every month, but you're paying for predictability.

The goal isn't the cheapest plan on paper.

It's the plan you'll still feel good about after your first unexpected hospital visit.
