Medicare Supplement Guide for 2026: The Ultimate Guide to Protecting Your Nest Egg
Medicare is a powerful healthcare system, but it was never designed to be “free.”
If you rely solely on Original Medicare (Part A and Part B), you are exposing yourself to uncapped financial risk. Unlike most private insurance you had through an employer, Original Medicare has no maximum out-of-pocket limit.
If you have a $100,000 heart surgery, Medicare generally pays 80%, and you are responsible for the remaining 20%. That is a $20,000 bill—payable immediately.
This is where Medicare Supplement Insurance (Medigap) becomes your financial firewall.
For 2026, the stakes are higher. Medical inflation has driven up deductibles and copays, making the “gaps” in Medicare wider than before. Choosing the right Medigap plan is no longer just about health; it’s about asset protection.
At Trusted SR Solutions, we believe an educated client is a protected client. This guide covers what you need to know to choose the right Medigap plan for 2026, avoid overpaying, and help secure your financial future.
What Is Medicare Supplement (Medigap) Insurance?
Medicare Supplement insurance is a private policy designed to help pay the bills that Medicare leaves behind.
It works in tandem with your “Red, White, and Blue” card:
Primary payer: Original Medicare pays its share of approved health costs (usually 80% for Part B services after you meet the deductible).
Secondary payer: Your Medigap plan pays its share of remaining costs (the 20% coinsurance, and some or all deductibles and copays, depending on the plan).
The result: With a strong Medigap plan, you can have major surgery, weeks of cancer treatments, or frequent specialist visits and pay $0 or a very small deductible for Medicare-approved services.
The 3 “Freedom” Rules of Medigap
Unlike Medicare Advantage plans, which restrict you to local networks, Medigap offers broad healthcare freedom:
Nationwide access: You can see any doctor or hospital in the United States that accepts Medicare. If a provider takes Medicare, they must also take your standardized Medigap plan.
No referrals: You typically do not need a referral from a primary care doctor to see a specialist.
Guaranteed renewable: As long as you pay your premiums, the insurance company generally cannot cancel your policy or change your benefits because of your health status or claims history.
The “Big Three” Costs Medigap Helps Cover in 2026
To understand the value of these plans, you must understand the major costs they can help eliminate or reduce.
1. The Part A Hospital Deductible ($1,736)
In 2026, the Part A inpatient hospital deductible for a benefit period is $1,736.
Crucial detail: This is not an annual deductible. It is a per-benefit-period deductible. If you are hospitalized in January, you pay $1,736. If you go back in August and it is a new benefit period (generally 60+ days after discharge), you pay $1,736 again.
Medigap coverage: Most popular Medigap plans (including Plan G and Plan N) pay 100% of this Part A deductible.
2.The Part B Coinsurance (The Unlimited 20%)
This is the most dangerous gap. Medicare Part B pays 80% of approved outpatient bills (surgeries, chemotherapy, dialysis, doctor visits, durable medical equipment) after you meet the deductible.
Crucial detail: There is no built-in cap on your 20%.
20% of a $5,000 bill is manageable.
20% of a $200,000 chemotherapy regimen can be financially devastating.
Medigap coverage: Medigap plans that include Part B coinsurance benefits (such as Plans G and N) generally pay 100% of this 20% coinsurance for covered services.
3. The Part B Deductible ($283)
For 2026, the annual Part B deductible is $283. You must pay the first $283 of Part B-covered services each year before Medicare starts paying its share.
Medigap coverage:
Only “grandfathered” plans (Plan F and Plan C) cover this deductible.
Most new enrollees (first eligible for Medicare on or after January 1, 2020) pay this amount out of pocket once per year.
The Plans: Plan G vs. Plan N (The 2026 Showdown)
There are many Medigap lettered plans (A, B, D, K, L, M), but in most states today the market is dominated by two clear winners for people new to Medicare: Plan G and Plan N.
Understanding the difference between these two is the key to finding the right balance between monthly premiums and coverage.
Option 1: Plan G — The “Peace of Mind” Standard
Who it’s for: People who want very comprehensive coverage and dislike surprise medical bills.
Plan G is widely seen as the “gold standard” Medigap plan for those first eligible for Medicare after 2020.
What it covers:
The Part A deductible and most Part A coinsurance and hospital costs.
Part B coinsurance (the 20%) for covered services.
Skilled nursing facility coinsurance, blood, and foreign travel emergency (up to plan limits).
Part B excess charges, in states where they are allowed.
What you pay:
Your monthly Plan G premium.
The annual Part B deductible of $283.
After that, you typically pay $0 for the rest of the year for Medicare-approved services, as long as they are covered by Medicare and Medigap.
Why it’s popular: It largely eliminates the stress of copays and surprise bills. Whether you see the doctor once or 50 times, your exposure is usually limited to the annual Part B deductible plus your premium.
Option 2: Plan N — The “Value” Contender
Who it’s for: Healthy, budget-conscious beneficiaries who do not mind small copays in exchange for lower monthly premiums.
Plan N premiums are often lower than Plan G premiums in the same area, with typical savings in the mid-teens to around 20%, though exact differences vary by carrier and ZIP code.
The copays (after the $283 deductible in 2026):
Up to $20 for some office visits.
Up to $50 for emergency room visits (waived if you are admitted).
The excess charge risk:
Plan N does not cover Part B excess charges.
In states that allow excess charges, certain providers who do not accept Medicare assignment can bill you up to 15% above the Medicare-approved amount.
Trade-off: You accept a little “pay-as-you-go” cost sharing and the potential for excess charges in exchange for a lower monthly premium.
What Are Part B Excess Charges? (Crucial for Plan N Buyers)
Doctors and other providers who accept Medicare can participate in two ways:
Accept assignment: They agree to accept the Medicare-approved amount as payment in full. They cannot bill you above that amount.
Do not accept assignment: They can legally charge you up to 15% more than the Medicare-approved amount in most states. This extra 15% is called a Part B excess charge.
How Medigap plans treat excess charges:
Plan G: Covers 100% of Part B excess charges in states where these charges are permitted.
Plan N: Does not cover excess charges. If your doctor does not accept assignment and adds this charge, you pay it out of pocket.
Expert tip: Excess charges are not very common nationally and are banned in some states, but they can show up with certain specialists or branded clinics. If you choose Plan N, making a habit of asking, “Do you accept Medicare assignment?” is wise.
Why Can’t I Get Plan F? (The MACRA Law)
If you talk to neighbors who have been on Medicare for years, they may rave about Plan F, which covered virtually all Medicare-approved out-of-pocket costs, including the Part B deductible.
However, under the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015, Plans F and C are closed to newly eligible Medicare beneficiaries as of January 1, 2020.
If you first became eligible for Medicare before January 1, 2020, you may still be able to buy Plan F or keep it if you already have it.
If you became eligible for Medicare on or after January 1, 2020, you cannot buy Plan F or Plan C.
Good news: Plan G provides nearly the same coverage as Plan F. The main difference is that you pay the small Part B deductible yourself each year, and premiums for Plan G are often lower than for comparable Plan F policies.
How Medigap Pricing Works: Avoid “Teaser Rates”
Not all Medigap prices are created equal. Insurance companies use three main methods to price their policies, and the method can impact how much you pay over time.
1. Community-Rated (Best Long-Term Stability)
Everyone enrolled with the carrier in that area pays the same base premium, regardless of age.
Your premium does not increase just because you get older (though it can increase due to inflation, claims experience, or other factors).
2. Issue-Age-Rated (Great for Younger Seniors)
Your premium is based on your age when you first buy the policy.
If you buy at 65, you pay the 65-year-old rate going forward, with future increases generally tied to inflation or other non-age factors, not to your aging.
3. Attained-Age-Rated (Most Common / Most Volatile)
Your premium is based on your current age.
It typically goes up every year as you get older, in addition to any general rate increases.
Warning: A plan that looks cheap at 65 can become expensive at 80 if it is heavily age-rated. A key part of our role is reviewing long-term rate history, not just today’s price.
Three Insider Ways to Save Money on Medigap
1. The Household Discount (HHD)
Many carriers offer a Household Discount (often in the 5%–12% range) if:
You and your spouse or household member both enroll with the same company, or
You live with another adult and meet the carrier’s specific rules, even if they are not on a Medigap policy.
Example:
On a $150 monthly premium, a 12% discount saves $18/month, or $216/year per person. Over 10 years, that is more than $4,000 in potential savings for a couple.
2. Comparing “Book Rates” vs. Introductory Offers
Some carriers lead with very low “teaser” or “introductory” rates and then apply large increases after the first year.
We focus on:
Carriers with stable, moderate annual increases (for example, in the low single digits when possible),
Versus carriers with a history of sharp 8%–10%+ jumps.
3. Using State-Specific “Birthday” and “Anniversary” Rules
Several states offer special rules that let you change Medigap policies with relaxed or no medical underwriting during certain windows.
These options can help you shop for lower rates periodically while keeping your health screening risk low or zero.
The Medical Underwriting Trap: Why You Must Act Early
The most critical timing rule with Medigap is your Open Enrollment Period (OEP) for Medigap.
This is a 6-month window that starts the month you are both 65 or older and enrolled in Medicare Part B.
During this OEP, you can buy any Medigap plan sold in your state from any company, regardless of your health.
After OEP, you may have to go through medical underwriting.
Common mistake:
Many people start on a Medicare Advantage plan thinking they can switch later.
Reality:
If your health worsens, it may be harder or impossible to pass underwriting for a new Medigap plan.
Medigap vs. Medicare Advantage: Key Differences
Medicare Supplement offers broad provider access and predictable costs.
Medicare Advantage relies on networks, copays, and annual plan changes.
