Medigap 2027 Changes: High-Deductible Plan G Rises to $3,050

Medicare Supplement Insurance beneficiaries have several new numbers to know for 2027.

The Centers for Medicare & Medicaid Services (CMS) has set the 2027 high-deductible amount for Medigap Plans F, G and J at $3,050.

CMS also finalized new annual out-of-pocket limits for Medigap Plans K and L:

Plan K: $8,360

Plan L: $4,180

All three 2027 amounts take effect on January 1, 2027.

The changes do not mean every Medigap policy will cost more by the same amount. CMS sets these specific federal deductible and out-of-pocket thresholds, while private insurance companies set Medigap premiums. Premiums can vary by insurer, location, plan and pricing method.

Here is what is changing in 2027, how high-deductible Plan G works, and what beneficiaries should compare before choosing or changing Medicare Supplement coverage.

Medigap 2027 Changes at a Glance

Medigap cost	2026	2027	Increase
High-deductible Plan G	$2,950	$3,050	+$100
High-deductible Plan F	$2,950	$3,050	+$100
High-deductible Plan J	$2,950	$3,050	+$100
Plan K out-of-pocket limit	$8,000	$8,360	+$360
Plan L out-of-pocket limit	$4,000	$4,180	+$180

CMS announced the new high-deductible amount and Plan K/L limits on October 2, 2026.

What Is the High-Deductible Medigap Plan G Deductible for 2027?

The annual high-deductible amount for Medigap Plan G will be:

$3,050 in 2027

The 2026 amount is:

$2,950

That means the deductible increases by:

$3,050 − $2,950 = $100

Percentage increase:

$100 ÷ $2,950 × 100 ≈ 3.39%

CMS says the high-deductible amount for Plans F, G and J is adjusted annually using the Consumer Price Index for All Urban Consumers, or CPI-U. For the 2027 calculation, CMS used a 3.40% applicable CPI-U increase and rounded the resulting deductible to the nearest $10.

The official CMS announcement describes the $3,050 amount as the annual out-of-pocket expenses, excluding premiums, that a beneficiary must pay before a high-deductible Medigap policy begins paying benefits.

How Does High-Deductible Plan G Work?

High-deductible Plan G is a version of standardized Medigap Plan G.

Instead of the Medigap policy immediately paying its normal share of covered Medicare cost sharing, the beneficiary first pays Medicare-covered expenses that count toward the high-deductible requirement.

For 2027, that requirement is:

$3,050

Medicare explains that the high-deductible amount can include Medicare-covered costs such as applicable deductibles, coinsurance and copayments. After the annual high-deductible requirement is satisfied, the policy begins paying according to the standardized benefits of the plan.

The trade-off is straightforward:

High-deductible Plan G may have a lower monthly premium, but the beneficiary accepts more potential out-of-pocket spending before the Medigap policy starts paying.

Whether that trade-off makes sense depends on the premium difference, expected medical use and the beneficiary’s ability to handle an unexpected medical bill.

High-Deductible Plan G vs. Regular Plan G

Regular Plan G and high-deductible Plan G share the same underlying standardized Plan G benefit structure, but they begin paying differently.

Regular Plan G

Standard Plan G covers most of the Medicare cost-sharing categories assigned to Plan G under the federal standardized benefit design.

It does not cover the Medicare Part B deductible for people who are subject to the post-2020 federal restriction on first-dollar coverage.

High-Deductible Plan G

High-deductible Plan G requires the beneficiary to meet the annual high-deductible threshold before the policy begins paying its normal Plan G benefits.

For 2027, that threshold is:

$3,050

This is why readers should be careful with the phrase “Plan G deductible.” The $3,050 amount specifically applies to the high-deductible version of Plan G. It is not a new $3,050 deductible imposed on every regular Plan G policy.

Does the $3,050 High Deductible Include Premiums?

No.

CMS specifically states that the high-deductible amount represents annual out-of-pocket expenses excluding premiums that a beneficiary pays before the high-deductible Medigap policy begins paying benefits.

That means the monthly Medigap premium is separate from the $3,050 threshold.

A beneficiary comparing high-deductible Plan G with standard Plan G should therefore consider both the annual premium difference and the additional out-of-pocket exposure created by the high deductible.

Who Can Buy High-Deductible Plan G?

CMS says high-deductible Plan G is available to people who are new to Medicare on or after January 1, 2020, subject to availability and Medigap enrollment rules.

For this federal rule, CMS identifies people new to Medicare as those who turn 65 on or after January 1, 2020, or first become eligible for Medicare due to age, disability or end-stage renal disease on or after that date.

Actual policy availability still depends on the insurers selling Medigap coverage in a person’s state or area.

Can Everyone Buy Medigap Plan F in 2027?

No.

Federal law restricts the sale of Medigap Plans C and F to certain beneficiaries because those plans can cover the Medicare Part B deductible.

CMS says the high-deductible version of Plan F is only available to people who were not considered new to Medicare on or after January 1, 2020.

People who were eligible for Medicare before that cutoff may still be able to buy Plan F if an insurer offers it and they meet applicable enrollment requirements.

People who already have Plan F are not required to drop it simply because newer beneficiaries cannot generally buy it.

What About Medigap Plan J?

Plan J appears in the CMS high-deductible announcement because older Plan J policies can still exist.

However, CMS notes that Plan J could no longer be sold after June 1, 2010.

The new $3,050 high-deductible amount therefore matters only to people who still hold an applicable older high-deductible Plan J policy. It is not a new Plan J option available for purchase in 2027.

What Is the Medigap Plan K Out-of-Pocket Limit for 2027?

The annual Medigap Plan K out-of-pocket limit will be:

$8,360 in 2027

The 2026 limit is:

$8,000

Increase:

$8,360 − $8,000 = $360

Percentage increase:

$360 ÷ $8,000 × 100 = 4.5%

Plan K generally pays 50% of several covered cost-sharing categories under the standardized Medigap benefit design.

What Is the Medigap Plan L Out-of-Pocket Limit for 2027?

The annual Medigap Plan L out-of-pocket limit will be:

$4,180 in 2027

The 2026 limit is:

$4,000

Increase:

$4,180 − $4,000 = $180

Percentage increase:

$180 ÷ $4,000 × 100 = 4.5%

Plan L generally pays 75% of several standardized cost-sharing categories where Plan K pays 50%.

What Happens After You Reach the Plan K or Plan L Out-of-Pocket Limit?

Plans K and L have annual out-of-pocket limits built into their standardized benefit designs.

Medicare explains that after a beneficiary reaches the plan’s yearly out-of-pocket limit and the annual Medicare Part B deductible, Plan K or Plan L pays 100% of covered services for the rest of the calendar year.

For 2027, the Medigap plan-specific limits are:

Plan K: $8,360

Plan L: $4,180

The Medicare Part B deductible is a separate Medicare amount and should not be confused with the Plan K or Plan L out-of-pocket limit.

Plan K vs. Plan L in 2027

Feature	Plan K	Plan L
Typical share of several standardized cost-sharing benefits	50%	75%
2027 out-of-pocket limit	$8,360	$4,180
Premium	Varies	Varies

There is no single national Plan K or Plan L premium.

Consumers should compare actual quotes available in their area.

Are Medigap Premiums Going Up in 2027?

There is no single nationwide Medigap premium for 2027.

The new $3,050 high-deductible threshold and the Plan K/L limits do not determine what every insurer will charge each month.

Medigap premiums can vary based on the insurance company, plan letter, where the beneficiary lives, how the insurer prices its policies and other factors allowed under federal and state rules.

That means two companies can charge very different premiums for the same standardized Plan G benefit package.

How Are Medigap Plans Standardized?

In most states, Medigap policies are standardized and identified by plan letters.

Medicare lists standardized plan types including:

A, B, C, D, F, G, K, L, M and N

The standardized benefits for the same plan letter are generally the same regardless of which insurance company sells the policy.

The premium can be different.

Massachusetts, Minnesota and Wisconsin use different Medigap standardization systems.

What Does Medigap Usually Not Cover?

Medigap generally does not cover long-term custodial care, routine vision care, dental care, hearing aids, eyeglasses, private-duty nursing or prescription drugs in modern Medigap policies.

People using Original Medicare with a newer Medigap policy generally need separate Medicare Part D coverage if they want prescription drug insurance.

Medigap Is Not the Same as Medicare Advantage

Medigap is supplemental insurance used with Original Medicare.

Medicare Advantage is an alternative way to receive Medicare Part A and Part B benefits through a private Medicare-approved plan.

A Medigap policy generally cannot be used to pay Medicare Advantage cost sharing.

Someone considering a switch between Medicare Advantage and Original Medicare with Medigap should pay close attention to Medigap eligibility before dropping existing coverage.

Be Careful Before Dropping a Medigap Policy

Beneficiaries do not always have an unlimited federal right to buy any Medigap policy whenever they want.

Outside the six-month Medigap Open Enrollment Period and specific guaranteed-issue situations, a person may have fewer policy choices, may have to pay more, or may be denied a policy based on medical underwriting where allowed.

State law can provide additional consumer protections.

When Is the Best Time to Buy Medigap?

For most people age 65 or older, the six-month Medigap Open Enrollment Period starts the first day of the month they are both age 65 or older and enrolled in Medicare Part B.

During this protected period, insurers generally cannot use medical underwriting to deny the applicant a Medigap policy or charge a different price because of health problems.

Does the October 15–December 7 Medicare Open Enrollment Period Apply to Medigap?

Not in the same way.

The annual October 15–December 7 Medicare Open Enrollment Period primarily applies to Medicare Advantage and Medicare prescription drug plan changes.

It is not a nationwide annual Medigap open-enrollment period guaranteeing every beneficiary the right to switch Medicare Supplement policies without underwriting.

Medigap has separate enrollment and guaranteed-issue rules.

High-Deductible Plan G Example for 2027

Suppose a high-deductible Plan G policy saves $100 per month compared with a regular Plan G quote.

Annual premium savings:

$100 × 12 = $1,200

But that does not automatically make high-deductible Plan G $1,200 cheaper overall.

The beneficiary is accepting additional potential Medicare-covered out-of-pocket spending before the policy begins paying.

A better comparison is:

Annual premium savings vs. potential additional out-of-pocket costs before the $3,050 deductible

Actual premium differences vary by insurer and location.

How Medigap Fits Into a 2027 Retirement Budget

A beneficiary using Original Medicare with Medigap may have several separate health-care costs, including the Medicare Part B premium, monthly Medigap premium, separate Part D premium, applicable deductibles and expenses Medicare and Medigap do not cover.
