Medigap Plan G Cost 2026: What You Will Pay

If you are turning 65 or already on Medicare, you have probably heard that Original Medicare (Part A and Part B) covers a lot but not everything. There are deductibles, coinsurance, and copayments that can add up quickly. That is where a Medigap policy comes in. Medigap Plan G is one of the most popular supplemental insurance plans because it covers nearly all of those out-of-pocket gaps. But the big question for many people is: what will Medigap Plan G cost in 2026? Understanding the pricing landscape now can help you budget, compare insurers, and lock in a rate before any major changes take effect.

In this article, we break down the components that drive Plan G premiums, what to expect in 2026, how to compare quotes, and strategies to keep your costs manageable. Whether you are enrolling for the first time or considering switching plans, this guide gives you the facts you need to make an informed decision.

What Medigap Plan G Covers in 2026

Medigap Plan G is standardized by the federal government, which means the basic benefits are the same no matter which insurance company you buy it from. In 2026, Plan G will cover: Part A hospital coinsurance and hospital costs up to an additional 365 days after Medicare benefits are exhausted, Part A deductible, Part A hospice care coinsurance or copayment, Part B coinsurance or copayment (generally 20% of the Medicare-approved amount), blood (first three pints), and Part B excess charges (the extra 15% some doctors can charge above Medicare’s approved amount). The only major out-of-pocket cost not covered by Plan G is the Part B deductible, which is $257 in 2026.

Because Plan G covers Part B excess charges, it offers more comprehensive protection than Plan N, which does not. Many beneficiaries choose Plan G for its predictability: once you pay the monthly premium and the Part B deductible, you have virtually no other cost-sharing for the rest of the year. This makes Plan G a strong option for those who want maximum coverage and minimal surprise bills.

Key Factors That Influence Medigap Plan G Cost in 2026

While the coverage is standardized, the premium you pay for Plan G can vary widely depending on several factors. Insurance companies use different pricing methods, and understanding them can save you hundreds of dollars a year.

Attained-Age vs. Issue-Age vs. Community-Rated Pricing

Most Medigap policies use one of three rating methods:

• Attained-age rating: Your premium is based on your current age and increases as you get older. This often starts with lower premiums but can lead to significant increases over time.
• Issue-age rating: Your premium is based on your age at the time of purchase. It will not increase because you get older, though it can still rise due to inflation or other factors.
• Community-rated (no-age) pricing: Everyone in a given area pays the same premium regardless of age. These plans tend to have stable premiums but may start higher for younger enrollees.

In 2026, many insurers are expected to continue using attained-age rating for Plan G. If you are in your late 60s or early 70s, an issue-age or community-rated plan might offer more predictable long-term costs. When comparing quotes, ask each insurer which rating method they use and request projected premiums for the next five to ten years.

Geographic Location and Regional Variations

Your zip code plays a major role in determining your Medigap Plan G cost in 2026. Premiums vary by state, county, and even city due to differences in healthcare costs, state regulations, and insurer competition. For example, a Plan G policy in a high-cost metropolitan area like New York City or Los Angeles may cost twice as much as the same plan in a rural area in the Midwest. Some states, such as Massachusetts, Minnesota, and Wisconsin, have their own Medigap standardization rules, which can affect pricing. Always compare plans from multiple insurers in your specific area to find the best rate.

Discounts and Underwriting Factors

Many insurers offer discounts that can lower your premium. Common discounts include household discounts (if you and your spouse both buy a policy from the same company), annual pay discounts (paying the full year upfront instead of monthly), and electronic funds transfer discounts. Additionally, if you are enrolling during your Medigap Open Enrollment Period (the six-month window that starts when you are 65 and enrolled in Part B), you cannot be denied coverage or charged more due to pre-existing conditions. If you apply outside this window, insurers can use medical underwriting, which may result in higher rates or denial. Locking in a policy during open enrollment is one of the best ways to secure a lower cost.

Average Medigap Plan G Cost in 2026: National Estimates

Based on 2025 pricing trends and projected inflation, the national average monthly premium for Medigap Plan G in 2026 is expected to range from $120 to $220 per month. However, some high-cost areas may see premiums of $300 or more, while low-cost regions could have policies as low as $90 per month. These estimates assume a 65-year-old nonsmoker in good health. If you smoke, have certain health conditions, or are older at enrollment, expect higher rates.

It is important to remember that premiums can increase each year due to medical inflation, insurer rate adjustments, and changes in Medicare costs. While the Part B deductible for 2026 is set at $257, the Part A deductible (covered by Plan G) is $1,732 per benefit period. Plan G covers that deductible, which is a significant savings for anyone hospitalized. Over the course of a year, paying a $150 monthly premium for Plan G plus the $257 Part B deductible totals $2,057, which is often less than what you would pay in coinsurance without supplemental coverage.

How to Compare Plan G Quotes for 2026

Because Medigap Plan G is standardized, comparing quotes is straightforward in theory, but the premiums can vary by hundreds of dollars between companies. Here is a step-by-step approach to finding the best rate for 2026.

First, gather your basic information: your date of birth, zip code, smoking status, and any current health conditions. Second, request quotes from at least three to five reputable insurers. You can do this through an independent broker, an online comparison tool, or directly on insurer websites. Third, compare not only the monthly premium but also the rating method, discount opportunities, and the company’s financial strength rating (look for A or A+ ratings from AM Best). Fourth, read the fine print on rate increase history. Some companies have a reputation for larger or more frequent premium hikes. Finally, consider the insurer’s customer service record and claims processing speed. A slightly higher premium with a top-rated company may be worth it for peace of mind.

When comparing, remember that the cheapest plan today may not be the cheapest in five years. A plan with a low introductory rate using attained-age pricing could become expensive as you age. Conversely, a community-rated plan with a slightly higher initial premium might save you money over the long term.

Strategies to Lower Your Medigap Plan G Cost in 2026

Even if you are on a fixed income, there are several legitimate ways to reduce what you pay for Plan G without sacrificing coverage.

• Enroll during your open enrollment period. This is the single most important step. You cannot be turned down or charged more for pre-existing conditions, and you lock in the lowest possible rate for your age and location.
• Take advantage of household discounts. If your spouse is also enrolling in a Medigap plan, ask about a multi-policy discount. Some insurers offer 5% to 10% off each premium.
• Pay annually. Many companies offer a discount of 5% to 8% if you pay the full year’s premium upfront rather than monthly.
• Consider a high-deductible Plan G. In some states, a high-deductible version of Plan G is available. It has a lower monthly premium but requires you to pay a deductible (around $2,800 in 2026) before coverage kicks in. This can be a good option if you are generally healthy and want to avoid high monthly costs.
• Shop around periodically. While you generally cannot switch Medigap plans without underwriting after your open enrollment period, some states allow you to change plans during certain windows. If your premiums have increased significantly, compare rates and see if you qualify for a lower-cost policy.

One often overlooked method is working with an independent broker who can compare plans from multiple carriers. Brokers are paid by the insurance company, not by you, and they can help you identify discounts and rating methods that fit your situation. They can also explain the nuances of each plan and help you avoid costly mistakes.

Will Medigap Plan G Cost More in 2026 Than 2025?

Historically, Medigap premiums have increased each year, and 2026 is expected to follow that trend. The Centers for Medicare & Medicaid Services (CMS) projects that overall healthcare costs will rise by 3% to 5% annually. Most insurers adjust their Medigap rates accordingly. However, the increase is not uniform. Some companies may raise rates by only 2%, while others may increase by 8% or more. This is why it is crucial to review your policy’s rate increase history before enrolling. If you are already on a Plan G, you may receive a notice of a premium increase for 2026. You can accept the increase, or if you are within a guaranteed issue period (such as if your current insurer is leaving the market), you can switch to a different company without underwriting.

Frequently Asked Questions About Medigap Plan G Cost in 2026

Is the Medigap Plan G premium tax-deductible?

Yes, in some cases. If you itemize deductions on your federal tax return, you can deduct medical expenses that exceed 7.5% of your adjusted gross income. Medigap premiums count as a medical expense. However, if you are self-employed, you may be able to deduct the cost directly as a health insurance deduction. Consult a tax professional for your specific situation.

Can I switch from Plan G to a cheaper plan later?

You can switch at any time, but unless you qualify for a guaranteed issue right (such as moving out of your plan’s service area or losing your current coverage), you will have to go through medical underwriting. If you have developed health conditions since enrolling, you may be denied or charged higher rates. It is generally better to choose a plan you can afford long-term from the start.

Does Medigap Plan G cover prescription drugs?

No. Medigap policies sold to new enrollees after January 1, 2006, are not allowed to cover prescription drugs. You will need a separate Medicare Part D plan for drug coverage. Some insurers offer a bundled plan that includes both a Medigap policy and a Part D plan, but they are separate contracts.

What is the difference between Plan G and Plan N in 2026?

Plan G covers Part B excess charges and has no copayments for doctor visits or emergency room visits. Plan N does not cover excess charges and requires a $20 copay for some doctor visits and a $50 copay for emergency room visits (if not admitted). Plan N typically has a lower monthly premium than Plan G. For a detailed cost comparison, see our article on Understanding Medigap Plan N Benefits: Cost Comparison by Providers.

How do I find the cheapest Medigap Plan G in my area for 2026?

Start by using online comparison tools that allow you to enter your zip code and age. Compare at least five insurers. Look for companies that use issue-age or community-rated pricing if you want stable premiums. Also, check if the insurer offers any discounts. If you need personalized assistance, call 833-203-6742 to speak with a licensed agent who can help you find the best rate.
