Medicare Supplement Plan G vs Plan N: Cost Comparison

Choosing between Medicare Supplement Plan G and Plan N often comes down to a single question: do you want to pay more upfront in premiums for near-complete coverage, or save on monthly costs and accept a few copays when you see the doctor? Both plans are popular Medigap options that fill the gaps left by Original Medicare, but their cost structures differ in ways that can add up to hundreds or even thousands of dollars per year depending on your health and how often you use medical services. This Medicare Supplement Plan G vs Plan N cost comparison breaks down premiums, out-of-pocket expenses, and the fine print that carriers do not always highlight, so you can decide which plan aligns with your budget and healthcare needs.

What Plan G and Plan N Cover Beyond Original Medicare

Before comparing costs, it helps to understand what each plan actually pays. Both Plan G and Plan N are standardized by the federal government, meaning the core benefits are identical across every insurance carrier. The differences lie in how they handle certain charges, particularly the Part B deductible, excess charges, and office visit copays.

Plan G covers nearly everything that Original Medicare does not, with one exception: you must pay the Part B deductible yourself. In 2026, that deductible is $257 per year (subject to annual updates). After you meet it, Plan G pays 100% of covered hospital and medical costs, including Part B excess charges, which are amounts above what Medicare approves that some providers may bill. Plan G also covers foreign travel emergency care, skilled nursing facility coinsurance, and Part A hospice care coinsurance.

Plan N, by contrast, also requires you to pay the Part B deductible, but it introduces copayments for certain services. You will pay up to $20 for some office visits and up to $50 for emergency room visits (waived if you are admitted). Plan N does not cover Part B excess charges, meaning you could be responsible for the difference if a provider charges more than Medicare's approved amount. Like Plan G, Plan N covers foreign travel emergency care, skilled nursing facility coinsurance, and hospice care coinsurance.

The practical takeaway: Plan G offers more comprehensive financial protection, while Plan N shifts some routine costs to you in exchange for lower premiums. Understanding these coverage differences is the first step in the cost comparison.

Premium Pricing Methods: Community-Rated vs Issue-Age vs Attained-Age

The premium you pay for Plan G or Plan N depends not only on the plan letter but also on how the insurance carrier prices its policies. There are three main pricing methods, and they can significantly affect your long-term costs.

• Community-rated: Everyone in the same geographic area pays the same premium regardless of age. Insurers may still raise rates due to inflation or claims experience, but your age does not trigger increases.
• Issue-age-rated: Your premium is based on your age at the time you buy the policy. It may increase due to inflation, but not because you get older.
• Attained-age-rated: Your premium increases as you age, often in steps. This means the premium you pay at 65 will be lower than what you pay at 75, even if the insurer never raises rates for other reasons.

Attained-age plans often have the lowest starting premiums, which can be attractive to new enrollees. However, over a 20-year retirement, the cumulative cost may be higher than a community-rated or issue-age plan. When comparing Plan G vs Plan N costs, ask each carrier which pricing method they use and request a historical rate increase summary. A plan with a low introductory premium but a history of double-digit rate hikes could cost you far more in the long run.

It is also worth noting that some carriers offer household discounts if more than one person in the home enrolls, and some may offer discounts for paying annually rather than monthly. These small adjustments can tip the scales in a close cost comparison.

Side-by-Side Cost Comparison: Premiums and Out-of-Pocket

To make a meaningful Medicare Supplement Plan G vs Plan N cost comparison, you need to look at both the monthly premium and the potential out-of-pocket costs. The table below summarizes the key differences. Note that actual premiums vary by ZIP code, age, tobacco use, and carrier, so use these figures as a general guide.

As the table shows, Plan N generally has lower monthly premiums, often by $30 to $50 per month compared to Plan G. However, that savings can be eroded by copays and excess charges if you see specialists frequently or if you live in an area where excess charges are common. For example, if you visit the doctor 10 times per year, the $20 copays add up to $200 annually. Add the $257 deductible, and your out-of-pocket costs under Plan N could reach $457 or more before you factor in any excess charges. Under Plan G, your only out-of-pocket cost (beyond the premium) is the $257 deductible, assuming you see Medicare-participating providers.

To estimate your total annual cost, use this simple framework:

1. Multiply the monthly premium by 12 to get the annual premium.
2. Add the Part B deductible ($257 in 2026).
3. For Plan N, add estimated copays: $20 times the number of office visits, plus $50 for each ER visit (if not admitted).
4. For Plan N, add any potential excess charges (ask your providers if they accept Medicare assignment).
5. Compare the totals. If you are generally healthy and rarely see the doctor, Plan N may cost less overall. If you have chronic conditions or see specialists often, Plan G may be the better financial choice.

Keep in mind that the Part B deductible is set by Medicare and can change annually. Also, some carriers offer innovative benefits like gym memberships or telehealth services with certain plans, which can add value beyond the core coverage.

Part B Excess Charges and Copay Handling: The Hidden Cost Drivers

Part B excess charges are one of the most misunderstood aspects of Medigap cost comparisons. Medicare sets an approved amount for each service. Providers who accept Medicare assignment agree to charge no more than that amount. However, providers who do not accept assignment can charge up to 15% above the Medicare-approved amount. These extra charges are called excess charges.

Plan G covers 100% of Part B excess charges. Plan N does not cover them at all. If you see a provider who does not accept assignment, you could be billed the excess amount under Plan N. This is more common with certain specialists, such as some surgeons, psychiatrists, and podiatrists, or in certain geographic areas. If you have Plan N, it is wise to ask your doctors whether they accept Medicare assignment. If they do not, you may want to factor those potential charges into your cost comparison.

Copay handling is the other key difference. Plan N requires you to pay up to $20 for some office visits, including visits to specialists, and up to $50 for emergency room visits. These copays are set by the plan and apply each time you receive the service. Over a year, these copays can add up, especially if you have multiple chronic conditions requiring frequent monitoring. Plan G has no such copays, which simplifies budgeting: after the deductible, you essentially have no out-of-pocket costs for covered services.

For beneficiaries who value predictability, Plan G's lack of copays can be a significant advantage. For those who are comfortable with some variable costs, Plan N's lower premium may be worth the trade-off.

Which Plan Suits Different Healthcare Usage Patterns

The right choice between Plan G and Plan N often depends on your health status and how you use healthcare services. Here is how the two plans tend to fit different profiles.

Frequent specialists and high utilization: If you have chronic conditions such as diabetes, heart disease, or cancer, or if you see multiple specialists regularly, Plan G is often the more cost-effective option. The higher premium is offset by the absence of copays and coverage of excess charges. You will not have to think twice about scheduling an extra appointment or seeing a specialist who does not accept assignment. Over time, the savings on copays and excess charges can exceed the premium difference. In our guide on Medicare Supplement updates 2026, we explain how recent changes may affect plan costs and benefits, which can further inform your decision.

Low-utilization users: If you are generally healthy, rarely visit the doctor, and do not anticipate needing frequent specialist care, Plan N can save you money. The lower monthly premium puts more cash in your pocket each month, and you only pay copays when you actually use services. Even with a few office visits per year, the total annual cost may still be lower than Plan G. However, you should consider the risk of unexpected health issues: if you suddenly need extensive care, the copays and potential excess charges could add up quickly. Some people choose Plan N when they are healthy and later switch to Plan G during a Medigap open enrollment period, but switching may require medical underwriting in most states after the initial window.

Budget-conscious but risk-averse: Some beneficiaries prefer the predictability of Plan G even if it costs a bit more each month. Knowing that you will not face copays or excess charges can provide peace of mind, especially if you have a family history of health issues or simply prefer to avoid surprise bills.

It is also worth considering your travel habits. Both plans offer foreign travel emergency coverage, but if you travel frequently within the U.S. and see different providers, Plan G's excess charge coverage can be beneficial.

Rate Increase History by Carrier and How to Compare Quotes

One of the most overlooked factors in the Medicare Supplement Plan G vs Plan N cost comparison is the carrier's rate increase history. Two carriers may offer similar premiums today, but one may have a pattern of larger or more frequent increases. Over a 10- or 20-year retirement, these differences can be substantial.

When comparing quotes, ask each carrier or your agent for the following information:

• The pricing method used (community-rated, issue-age, or attained-age).
• The average annual rate increase over the past 5 to 10 years, if available.
• Any recent or pending rate filings in your state.
• Whether the carrier offers household discounts or other premium reductions.

You can also check with your state's department of insurance to see rate filings. Some states publish historical rate increases by carrier and plan. This information can help you avoid a carrier that has been aggressively raising rates.

To compare quotes effectively, work with a licensed insurance agent who can pull quotes from multiple carriers in your area.
