Standard Medicare Supplement Plan G generally costs more in monthly premiums but begins providing its Plan G benefits without requiring you to first satisfy the separate High-Deductible Plan G annual deductible. High-Deductible Plan G generally offers a lower monthly premium, but you must pay Medicare-covered out-of-pocket costs up to its annual deductible before the Medigap policy begins paying.

For 2026, that High-Deductible Plan G deductible is $2,950. CMS adjusts the amount annually, so shoppers considering coverage for 2027 should verify the official 2027 amount once CMS publishes it.

So which is better?

It depends on whether you value lower monthly premiums or greater predictability when you use healthcare.

This isn’t simply a question of which policy has the cheaper premium.

The better comparison is:

How much am I saving in premiums—and how much additional financial responsibility am I accepting to get those savings?

That’s what we’ll break down.

First: What Does Standard Plan G Cover?

Medigap works alongside Original Medicare.

Original Medicare pays its share first, and your Medigap policy helps cover certain remaining Medicare-approved costs according to the standardized benefits of your policy.

Standard Plan G covers:

• Part A coinsurance and additional hospital costs
• Part B coinsurance
• First 3 pints of blood
• Part A hospice coinsurance/copayments
• Skilled nursing facility coinsurance
• Part A deductible
• Part B excess charges
• 80% of qualifying foreign travel emergency costs, subject to plan limits

One major item Plan G does not cover for people newly eligible for Medicare after 2019 is the Medicare Part B deductible.

The 2026 Part B deductible is $283.

You can see the standardized benefits directly in .

What Is High-Deductible Plan G?

High-Deductible Plan G—often shortened to HDG—provides the Plan G benefit structure, but there’s an important condition:

You must first satisfy the high annual deductible before the Medigap policy begins paying benefits.

CMS states that for 2026, the deductible is:

$2,950

The deductible represents annual out-of-pocket expenses, excluding premiums, that the beneficiary must pay before the high-deductible Medigap policy begins paying.

That’s what makes the premium cheaper.

You’re accepting more of the initial financial risk.

---

Standard Plan G vs HDG: Think of It as a Trade-Off

Here’s the easiest way to understand the choice.

Standard Plan G

Pay more each month.

In exchange:

Transfer more of your Medicare cost-sharing risk to the insurance company sooner.

---

High-Deductible Plan G

Pay less each month.

In exchange:

Keep more of the initial Medicare cost-sharing risk yourself.

Neither approach is automatically better.

They’re different ways of financing healthcare risk.

---

The Number That Matters Isn’t Just the Premium

Suppose you’re comparing:

Standard Plan G

$_____ per month

versus

High-Deductible Plan G

$_____ per month

Don’t stop there.

Calculate:

Annual Premium

Monthly premium × 12

Then calculate:

Annual Premium Difference

Standard Plan G annual premium − HDG annual premium

Now compare that savings with the amount of additional out-of-pocket exposure you’re accepting.

Use this worksheet:

	Standard Plan G	High-Deductible G
Monthly premium	$_____	$_____
Annual premium	$_____	$_____
HDG deductible	N/A	$2,950*
Part B deductible	Applicable	Counts toward HDG deductible
Premium difference		$_____
Potential healthcare spending before policy pays	Lower	Higher

*$2,950 is the official 2026 HDG deductible. Verify the 2027 amount once CMS publishes it.

---

Here’s a Better Way to Ask Whether HDG Is Worth It

Don’t ask:

“How much cheaper is High-Deductible Plan G?”

Ask:

“How much premium am I saving per year for accepting the additional deductible exposure?”

That’s a much more useful question.

---

Example: Comparing the Premium Savings

Let’s use hypothetical numbers strictly for illustration.

Suppose:

Standard Plan G = $200/month

High-Deductible Plan G = $80/month

The difference is:

$120/month

or:

$1,440 per year

Now you’re making a much clearer decision.

You’re potentially saving $1,440 in annual premiums in exchange for accepting substantially more initial out-of-pocket responsibility under HDG.

But this doesn’t automatically mean HDG is better—or worse.

Your actual outcome depends on how much Medicare-covered care you use.

---

Scenario 1: You Have a Low-Use Healthcare Year

Imagine you have:

• A few routine doctor visits
• Limited testing
• No hospitalization
• No major outpatient procedure
• Relatively little Medicare cost sharing

With Standard Plan G, you’re paying the higher premium regardless of how much care you use.

With HDG, you may save substantially on premiums while never reaching the high deductible.

In that type of year:

HDG may produce lower total spending.

But that’s a possibility—not a guarantee.

---

Scenario 2: You Have a High-Use Healthcare Year

Now imagine:

• Hospitalization
• Multiple specialist visits
• Outpatient procedures
• Physical therapy
• Diagnostic testing
• Other Medicare-covered services

With HDG, your Medicare cost sharing accumulates toward the high deductible before the Medigap policy starts paying.

With Standard Plan G, the policy begins covering its standardized Plan G benefits without requiring you to satisfy that separate $2,950 HDG deductible.

In a high-use year, the financial advantage of the lower HDG premium can narrow.

That’s why:

Premium alone doesn’t answer the question.

---

A Simple Break-Even Framework

Here’s one of the most useful ways to compare the two.

Let’s call:

S = Annual Standard Plan G premium

H = Annual HDG premium

D = High-Deductible Plan G deductible

Then:

Annual premium savings from HDG:

S − H

Compare that number with the additional out-of-pocket costs you could reasonably face under HDG.

For example:

Annual HDG Premium Savings	What It Means
$600	You’re saving $600/year to accept substantially more initial cost responsibility
$1,200	You’re saving $1,200/year
$1,800	You’re saving $1,800/year
$2,400	You’re saving $2,400/year

The bigger the premium difference, the more interesting HDG can become.

But this still isn’t a perfect mathematical break-even because your actual Medicare cost sharing depends on the healthcare services you receive.

---

The $2,950 Deductible Is Not Necessarily a Bill You Automatically Pay

This is an important distinction.

Some shoppers hear:

“HDG has a $2,950 deductible.”

and imagine receiving a $2,950 bill every January.

That’s not how it works.

The deductible represents applicable Medicare-covered out-of-pocket expenses that accumulate during the year before the Medigap policy begins paying.

If your Medicare cost sharing never reaches $2,950 in 2026, you don’t simply write the insurer a check for the difference.

CMS describes the deductible as annual out-of-pocket expenses that must be paid before the high-deductible policy begins paying.

That distinction makes HDG much easier to understand.

---

What Counts Toward the High-Deductible Plan G Deductible?

Generally, the Medicare-covered deductibles, coinsurance and copayments that the Medigap policy would otherwise cover count toward satisfying the high deductible.

Medicare explains that with high-deductible Plans F and G, you pay Medicare-covered costs—including applicable deductibles, copayments and coinsurance—up to the high-deductible amount before the Medigap policy begins paying.

For exact claims or unusual situations, verify how the insurer will credit the expense.

---

What Doesn’t the HDG Deductible Mean?

It doesn’t mean:

❌ Your monthly Medigap premiums count toward the deductible.

CMS explicitly identifies the deductible as out-of-pocket expenses excluding premiums.

It also doesn’t turn Plan G into Medicare Advantage.

You’re still using:

Original Medicare + Medigap

That distinction matters.

---

What About the Medicare Part B Deductible?

Standard Plan G does not cover the Part B deductible.

For 2026, Medicare’s Part B deductible is:

$283

according to .

With Standard Plan G, you remain responsible for that deductible.

With HDG, Medicare indicates that Medicare-covered deductibles and cost sharing you pay count toward satisfying the high-deductible requirement.

---

Which Person Might Prefer Standard Plan G?

Standard Plan G may appeal more to someone who says:

“I don’t want to worry as much about medical bills throughout the year.”

Potential reasons include:

✓ You prefer predictable healthcare budgeting

You’d rather pay more each month and reduce uncertainty when receiving Medicare-covered services.

✓ You use healthcare frequently

Multiple specialists, testing, procedures or other regular Medicare services may make predictable cost sharing more attractive.

✓ You don’t want to maintain a large medical reserve

Even if HDG could save money over time, you may simply prefer not to risk needing to cover a significant amount of cost sharing during a high-use year.

✓ Simplicity matters

Some beneficiaries like the straightforward nature of Standard Plan G.

You pay the premium.

You pay the Part B deductible.

Then Plan G covers its standardized benefits.

---

Who Might Prefer High-Deductible Plan G?

HDG may appeal more to someone who says:

“I’d rather keep my monthly premium lower and accept more financial responsibility if I actually need care.”

Potential reasons include:

✓ You’re comfortable with a higher deductible

You have enough savings to cover the potential cost sharing.

✓ Lower monthly fixed expenses matter

Reducing recurring premiums is a priority.

✓ You’re comfortable self-insuring part of the risk

You understand that the lower premium comes from retaining more initial financial responsibility.

✓ You want catastrophic-style Medigap protection

You may prefer paying routine Medicare cost sharing yourself while retaining Plan G protection after satisfying the high deductible.

---

The Emergency-Fund Question

This might be the most practical test for HDG.

Ask:

“If I had a high-use healthcare year, could I comfortably handle the deductible without creating financial stress?”

If the answer is:

“Absolutely.”

HDG may deserve serious consideration.

If the answer is:

“That would be difficult.”

Then the lower premium may not compensate for the budgeting uncertainty.

Insurance isn’t only about expected value.

It’s also about risk tolerance.

---

Compare 5 Years, Not Just Year One

This is another useful exercise.

Don’t evaluate:

$200 vs $80

and stop.

Instead, ask:

What could I pay in premiums over several years?

How might premiums increase?

How comfortable am I with the HDG deductible increasing over time?

What happens if I have several low-use years?

What happens if I have one major healthcare year?

Medicare notes that Medigap premiums can vary widely based on insurer, policy and location, and premium amounts can increase over time.

Review when comparing policies.

---

Don’t Forget the Insurance Company

Standardized Plan G benefits are standardized.

But that doesn’t mean every Plan G policy has the same price.

Medicare explains that the benefits within the same standardized Medigap plan letter are the same regardless of the insurance company selling it, while premiums can vary substantially between insurers.

So you shouldn’t only compare:

Plan G vs HDG

You may need to compare:

Carrier A Plan G

Carrier B Plan G

Carrier C Plan G

Carrier A HDG

Carrier B HDG

and so on.

Our [Compare Medicare Supplement Plans] resources can help you evaluate those differences.

---

Don’t Confuse Medigap Open Enrollment With Medicare Open Enrollment

This is particularly important because we’re discussing Plan G during the fall Medicare shopping season.

October 15–December 7 is not a universal annual Medigap Open Enrollment Period.

Your federal Medigap Open Enrollment Period generally lasts six months beginning when you’re 65 or older and enrolled in Medicare Part B.

During that period, insurers generally can’t deny you a Medigap policy based on pre-existing health problems.

After that period ends, you may face medical underwriting unless you have a guaranteed-issue right or other protection.

Medicare explicitly notes that your Medigap Open Enrollment Period is a one-time enrollment period and doesn’t repeat annually like Medicare Open Enrollment.

Read our [Medigap Open Enrollment Guide] before assuming you can switch between Standard Plan G and HDG whenever you want.

You can also review .

---

Don’t Assume You Can Switch Back Later

Suppose you choose HDG today.

Three years later, your healthcare needs change and you decide:

“I’ll just switch to Standard Plan G.”

That may not be as simple as it sounds.

Outside your Medigap Open Enrollment Period or another protected enrollment right, an insurer may use medical underwriting, and you may not be able to purchase the policy you want—or it may cost more.

That makes the long-term fit important.

Don’t choose HDG assuming Standard Plan G will always be available to you later without underwriting.

---

Plan G vs High-Deductible G: A Practical Scorecard

If This Sounds Like You…	Plan G	HDG
I prioritize predictable costs	★★★	★
I prioritize lower premiums	★	★★★
I have savings for unexpected medical costs	★★	★★★
I dislike large deductibles	★★★	★
I’m comfortable self-funding routine cost sharing	★	★★★
I want less exposure when I use care	★★★	★
I understand and can budget for the HDG structure	★★	★★★

This isn’t a recommendation or a scoring formula.

It’s simply a way to identify which trade-offs matter most to you.

Plan G vs HDG: Your Comparison Worksheet

Before choosing, fill this out:

Question	Standard G	HDG
Monthly premium	$_____	$_____
Annual premium	$_____	$_____
Annual premium difference	—	$_____
High deductible	N/A	$_____
Part B deductible	$_____	Included toward HDG accumulation
Comfortable with worst-case budgeting?	✓/✗	✓/✗
Current healthcare usage	_____	_____
Five-year premium outlook considered?	✓/✗	✓/✗
Underwriting implications considered?	✓/✗	✓/✗

Then ask yourself:

“Is the annual premium savings large enough for me to accept the additional financial exposure?”

That’s the question this comparison should ultimately answer.

---

Remember: Medigap Doesn’t Cover Everything

Neither Standard Plan G nor High-Deductible Plan G generally provides routine:

• Dental
• Vision
• Hearing aids
• Long-term care
• Outpatient prescription drug coverage

Medicare confirms that Medigap generally doesn’t cover those services, and Medigap policies sold after 2005 don’t include prescription drug coverage.

If you need outpatient prescription coverage, you can separately evaluate Medicare Part D.

See for more information.

---

So, Is High-Deductible Plan G Worth It?

It can be—but the lower premium alone doesn’t tell you.

High-Deductible Plan G can make sense for someone who:

✓ Wants lower fixed monthly costs

✓ Understands the deductible structure

✓ Has adequate savings

✓ Is comfortable retaining more initial healthcare risk

✓ Receives enough premium savings to justify that trade-off

Standard Plan G can make sense for someone who:

✓ Values predictability

✓ Wants less cost sharing when receiving Medicare-covered services

✓ Prefers paying more through premiums rather than assuming a larger deductible

✓ Doesn’t want to maintain as much cash specifically for medical cost sharing

Neither is automatically the winner.

The premium tells you what you pay to own the policy.

The deductible tells you how much risk you’re retaining.

You need to compare both.

Frequently Asked Questions

What is the difference between Plan G and High-Deductible Plan G?

Both use the Plan G benefit structure, but High-Deductible Plan G requires you to pay applicable Medicare-covered out-of-pocket costs up to an annual deductible before the Medigap policy begins paying. Standard Plan G doesn’t have that separate high deductible.

What is the High-Deductible Plan G deductible in 2026?

The official High-Deductible Plan G deductible for 2026 is $2,950. CMS adjusts the amount annually.

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

CMS has not yet published the official 2027 amount as of this article’s September 2026 publication date. Check the latest CMS announcement before purchasing 2027 coverage.

Is High-Deductible Plan G cheaper than Standard Plan G?

HDG generally has lower premiums, but actual premiums vary by insurer, location and individual rating factors. The lower premium comes with greater initial out-of-pocket responsibility.

Does Standard Plan G cover the Medicare Part B deductible?

No. Plan G doesn’t cover the Part B deductible. The 2026 Medicare Part B deductible is $283.

Do Plan G and High-Deductible Plan G include prescription drug coverage?

No. Modern Medigap policies don’t include outpatient prescription drug coverage. Beneficiaries who want prescription coverage can consider a separate Medicare Part D plan.

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

Possibly, but don’t assume you’ll automatically be able to switch. Outside your Medigap Open Enrollment Period or another guaranteed-issue situation, medical underwriting may apply depending on your circumstances and state protections.

Can Medicare Plan Assistance compare Plan G and HDG premiums for me?

Yes. Medicare Plan Assistance can help you compare available Medigap options and understand the premium-versus-deductible trade-off. Call (561) 808-9410.
