Medicare Supplement Plan G vs Plan N Illinois: Which Medigap Plan Is Right for You in 2026?

You’ve done the research. You know Original Medicare leaves significant gaps. You’ve narrowed your options down to Medigap Plan G and Plan N. And now you’re stuck — because from the outside, these two plans look almost identical. That feeling of being close to the finish line but still uncertain is completely normal. Plan G and Plan N genuinely are the two most competitive Medigap options on the market, and the difference between them comes down to a few structural details that can mean a great deal depending on how you use your healthcare.

If you’ve landed on this page searching for a clear breakdown of Medicare Supplement Plan G vs Plan N in Illinois, you’re in the right place. This guide was built specifically to cut through the noise and give you a plain-English comparison grounded in how these plans actually function — not insurance company marketing copy.

This guide was written with the expertise of Таня Данілкович, a licensed independent insurance broker with more than 15 years of experience helping Illinois, Florida, and Ohio residents navigate Medicare decisions with confidence. Before founding TD Integrity Insurance Solutions, Tanya worked as a Medicaid, SSI, and SNAP coordinator — a background that gives her a rare, inside-out understanding of how government health programs actually function in the real world, not just how they’re described in brochures. As an independent broker, Tanya works exclusively for her clients, not for any insurance carrier.

In the sections that follow, you’ll find a complete breakdown of what each plan covers, how they compare on real costs in Illinois, what the 2026 planning landscape looks like, and a practical framework to help you think through which plan fits your life — without pressure and without jargon.

What Is a Medigap Plan — and Why Does It Matter for Illinois Residents?

Medicare Supplement insurance — more commonly called Medigap — is private insurance designed to fill the coverage gaps that Original Medicare (Parts A and B) leaves behind. And those gaps are substantial. Original Medicare alone exposes beneficiaries to the Part A hospital deductible (set at $1,676 in 2025) and a 20% Part B coinsurance on outpatient services, with no annual out-of-pocket cap to protect against catastrophic costs. A serious illness or extended hospital stay can generate out-of-pocket expenses that accumulate quickly and unpredictably.

Medigap plans are federally standardized, which is one of the most important facts for any Illinois beneficiary to understand. Every insurance carrier offering Plan G in Illinois must provide exactly the same benefits as every other carrier offering Plan G. The coverage is identical no matter which company issues the policy. However — and this is a critical distinction — premiums for the same plan letter can vary significantly from one carrier to another, based on factors including age, gender, tobacco use, zip code, and available household discounts. This is why searching for Medigap Plan G in Illinois without comparing multiple carriers can mean overpaying for identical coverage.

Illinois residents have access to multiple top-rated carriers for both Plan G and Plan N. When Illinois residents want to compare Medigap policies in Illinois across multiple carriers simultaneously, an independent broker can do this at no cost to the consumer — and do it far more efficiently than calling each company individually. Working with an independent broker is the most effective way to ensure you’re seeing the full picture.

While plan benefits are standardized, the right plan for each individual depends on health history, anticipated frequency of care, and financial comfort with cost-sharing. The rest of this guide will help you think those factors through clearly.

Medigap Plan G in Illinois — Full Coverage Breakdown

Since Plan F was phased out for new Medicare enrollees in 2020, Medigap Plan G has become the most comprehensive option available to beneficiaries newly enrolling in Medicare. It now occupies the top tier of the Medigap market, and for good reason — it covers nearly every significant gap Original Medicare leaves behind.

Here is what Medigap Plan G covers in plain English:

• Part A hospital coinsurance and costs — Covers inpatient hospital care, including up to an additional 365 days after Medicare benefits are exhausted
• Part A deductible — Covers the full $1,676 Part A deductible (2025), meaning no out-of-pocket cost for a covered hospital admission after the plan satisfies this amount
• Part A hospice care coinsurance or copayment — Covered in full
• Skilled nursing facility coinsurance (Days 21–100) — Covered in full; a meaningful benefit, given how quickly those daily costs accumulate during an extended recovery
• First three pints of blood — Covered
• Part B coinsurance and copayments — After the annual Part B deductible is met, Plan G covers the standard 20% Medicare coinsurance on outpatient services — meaning no additional cost-sharing on covered doctor visits, specialist visits, outpatient procedures, or lab work
• Part B excess charges — Covers up to 15% above the Medicare-approved amount when a provider does not accept Medicare assignment. This is a benefit Plan N does not provide — and it matters more than many people initially realize
• Foreign travel emergency — Covers 80% of emergency medical care outside the U.S., up to the plan’s lifetime limit, for the first 60 days of a trip after a $250 deductible

The one gap in Plan G: It does not cover the Part B deductible, which is $257 in 2025 and is adjusted annually by Medicare. That is the single out-of-pocket cost a Plan G beneficiary pays before outpatient benefits kick in for the year.

People who tend to align well with Plan G share a recognizable profile: they see doctors or specialists regularly, they may be managing one or more ongoing health conditions, they value knowing exactly what their healthcare will cost each month regardless of how often they need care, and they prefer the certainty of a higher monthly premium over unpredictable cost-sharing at the point of care. In the Illinois Medigap market, Plan G is available from multiple top-rated carriers, with national average monthly premiums ranging from approximately $140 to $236 depending on age, zip code, and carrier — though actual Illinois rates require a localized quote to be meaningful. Understanding when your Medigap Open Enrollment Period begins is equally important, as timing affects both your access to coverage and the premiums you’ll pay.

Medigap Plan N in Illinois — Full Coverage Breakdown

Plan N is not a lesser plan — that framing leads people in the wrong direction. It is a structurally different plan built for a different risk and savings profile. Plan N covers the majority of the same core benefits as Plan G, with two meaningful structural differences that determine whether it delivers real value or creates financial exposure, depending entirely on the individual.

Here is what Medigap Plan N covers:

• Part A hospital coinsurance and costs (up to an additional 365 days) — same as Plan G
• Part A deductible ($1,676 in 2025) — same as Plan G
• Part A hospice care coinsurance or copayment — same as Plan G
• Skilled nursing facility coinsurance (Days 21–100) — same as Plan G
• First three pints of blood — same as Plan G
• Part B coinsurance — covered, with structured copayments (explained below)
• Foreign travel emergency (80%, first 60 days, after $250 deductible) — same as Plan G

Key Difference #1 — Copayments: Under Plan N, the beneficiary pays a copayment of up to $20 for some office visits and up to $50 for emergency room visits that do not result in an inpatient hospital admission. These copays apply after the Part B deductible is satisfied. For someone who sees their doctor twice a year, those copays are a manageable trade-off. For someone visiting multiple specialists throughout the year, they accumulate in ways that deserve careful calculation before enrollment.

Key Difference #2 — Part B Excess Charges: This is the most misunderstood difference between these two plans, and it deserves a clear explanation. Some doctors and providers in Illinois do not accept Medicare assignment — meaning they have not agreed to limit their fees to the Medicare-approved amount. These providers are legally permitted to charge up to 15% more than the Medicare-approved rate. Under Plan G, those excess charges are covered in full. Under Plan N, the beneficiary is responsible for paying them out of pocket. Illinois does have certain balance billing protections at the state level that may limit some of this exposure in practice — but the specifics of how those protections interact with real-world billing scenarios are exactly the kind of detail an Illinois-licensed broker should walk through with you individually. That nuance should not be navigated from a blog post alone.

Plan N does not cover the Part B deductible ($257 in 2025) — the same gap that exists in Plan G.

People who tend to align well with Plan N are generally in good health, visit their primary care provider infrequently, have verified that all of their preferred providers accept Medicare assignment — which effectively eliminates excess charge exposure — and are comfortable with occasional small copayments in exchange for a lower monthly premium. When comparing Medigap Plan N cost in Illinois, national average monthly premiums range from approximately $121 to $219, generally lower than Plan G’s range — though actual Illinois rates vary meaningfully by carrier, age, and zip code. A localized quote is essential to understanding your real savings.

Medicare Supplement Plan G vs Plan N Illinois — The Direct Comparison

Now that both plans have been explained individually, here is the side-by-side view across the dimensions that matter most for Illinois beneficiaries.

The table tells you what the features are. Here is what they mean in practical terms.

Plan G costs more per month but nearly eliminates financial surprises at the point of care. Once the annual Part B deductible is satisfied, a Plan G beneficiary generally pays nothing additional for covered services — regardless of how many times they see a doctor, visit a specialist, or undergo an outpatient procedure. The monthly premium essentially pre-pays for comprehensive coverage.

Plan N costs less per month but introduces two layers of variable exposure: the copayments, which are predictable but recurring, and the excess charge risk, which is unpredictable and entirely dependent on which providers the beneficiary sees. For people whose providers accept Medicare assignment, the excess charge risk disappears. For people whose providers don’t, it’s a real financial variable that should not be dismissed.

The most useful concept for making this decision is the break-even calculation: the real question is not ‘which plan is cheaper per month?’ but ‘at what point does my utilization of Plan N’s copay structure erase the premium savings?’ For someone visiting the doctor 8–10 times per year, copays alone could begin to close the monthly savings gap. For someone visiting twice a year, the math may favor Plan N significantly. This break-even calculation is highly personal — it depends on health history, frequency of care, provider assignment status, and how the individual values certainty versus variable cost risk.

A personalized breakdown of Medicare Supplement Plan G vs Plan N in Illinois — using current carrier quotes and a real picture of your health situation — delivers far more actionable value than any national comparison table can. Beyond Plan G vs Plan N, it’s worth knowing that premiums for the same plan letter can vary by hundreds of dollars per year between carriers, which is exactly why the ability to compare Medigap policies in Illinois across multiple top-rated companies at once is one of the most valuable things an independent broker provides.

Illinois-Specific Considerations for Choosing the Best Medigap Plan in 2026

Many Illinois residents searching for this information are planning ahead — approaching their 65th birthday, newly enrolled in Medicare Part B, or re-evaluating whether their current Medigap coverage still makes sense as 2026 approaches. This section is specifically for those forward-planning beneficiaries.

2026 cost-sharing context: Medicare cost-sharing amounts are reviewed and updated annually. The Part A deductible is $1,676 and the Part B deductible is $257 for 2025 — both figures that directly affect the relative value of Plan G and Plan N. As these baseline costs shift, the math around which plan delivers more value shifts with them. Any comparison done using 2025 figures should be refreshed with verified 2026 amounts before making a final enrollment decision.

Carrier premium adjustments: Illinois carriers review and adjust Medigap premiums on an annual basis. A premium spread that made Plan N the clear cost winner in one year may be narrower — or wider — the following year depending on how each carrier adjusts its rates. This is a strong argument for working with a broker who can pull current-year carrier quotes rather than relying on figures from a prior enrollment cycle.

The guaranteed issue window — and why timing is everything: The Medigap Open Enrollment Period begins on the first day of the month a beneficiary is both 65 or older and enrolled in Medicare Part B. This window lasts six months. During this period, a carrier cannot deny coverage or charge higher premiums based on health history or pre-existing conditions. Once this window closes, switching Medigap plans in Illinois may require medical underwriting — meaning a carrier can evaluate your health history and potentially deny or surcharge coverage. Understanding how the Medigap Open Enrollment Period works before it begins is one of the most important steps a new Medicare beneficiary can take.

Illinois balance billing protections: Illinois has state-level regulations that limit certain balance billing practices, which may reduce — though not eliminate — the real-world financial exposure that comes with Plan N’s excess charge gap. Because these protections involve specific state statutes that are subject to change and apply differently depending on provider, service type, and circumstance, the appropriate way to understand how they apply to your situation is to speak directly with an Illinois-licensed broker.

When Illinois residents ask about the best Medigap plans in Illinois for 2026, the honest answer is that the ‘best’ plan is not a universal designation. It is an individualized answer shaped by current carrier pricing, anticipated healthcare usage, and each person’s financial priorities. Medicare rules, deductible amounts, carrier pricing, and state-level protections are all subject to annual adjustment — which is exactly why working with a licensed broker using current data is the most reliable path to a confident 2026 decision.

Real-World Scenarios — Seeing Yourself in the Decision

Numbers and features only tell part of the story. The way these two plans actually play out in people’s lives depends on how they use their healthcare. The following hypothetical scenarios are designed to help readers see themselves in the comparison. These are illustrative examples, not real client stories, and individual circumstances always vary.

Scenario A — The Case for Plan G: Consider a hypothetical 65-year-old Illinois woman who has recently enrolled in Medicare Part B. She manages Type 2 diabetes and sees both her primary care physician and an endocrinologist regularly — typically 8–10 medical appointments per year, with one or two specialist procedures annually. Under Plan N, her $20 office visit copays would accumulate noticeably across those visits. Additionally, one of her specialists does not accept Medicare assignment, creating potential excess charge exposure each time she is seen. For someone in a situation like this, Plan G’s higher monthly premium purchases something concrete: the knowledge that after the annual Part B deductible is met, no additional cost-sharing surprises will emerge regardless of how many times she needs care. People managing ongoing health conditions deserve predictability, and Plan G is structurally built to provide it.

Scenario B — The Case for Plan N: Consider a hypothetical relatively healthy 67-year-old Illinois man who sees his primary care doctor once a year for a wellness visit and once more when a minor concern arises. He has confirmed that all of his providers accept Medicare assignment, effectively eliminating excess charge exposure. For someone in this position, the $20 copay twice a year amounts to $40 annually — a manageable trade-off for a meaningfully lower monthly premium. Over the course of a year, his Plan N savings could exceed $300–$600 compared to Plan G, depending on carrier pricing. For healthy, low-utilization beneficiaries in Illinois whose providers accept Medicare assignment, Plan N’s structure may deliver genuine and measurable savings.

Scenario C — The Case for Getting a Broker Comparison First: Consider a hypothetical 64-year-old Illinois woman approaching Medicare enrollment for the first time. She is in reasonable health but has a family history of heart disease, is uncertain which specialists she may need going forward, and is unsure whether her current primary care physician accepts Medicare assignment. She has heard she should ‘just go with Plan G to be safe’ but doesn’t want to overpay unnecessarily. For someone in this position — uncertain about future utilization, within the guaranteed issue window, facing a multi-year financial commitment — the lowest-risk move is to sit down with a licensed independent broker who can run real carrier quotes for both plans, ask the right questions about her provider relationships and health history, and help her model the financial scenarios before she commits to anything.

Why Tanya Danilkovich Recommends Working with an Independent Broker for This Decision

There is an important distinction that many Medicare beneficiaries don’t learn until after they’ve already enrolled: the difference between a captive agent and an independent broker. A captive agent represents one insurance carrier — their job is to sell that company’s products, and their options are limited to what their employer offers. An independent broker like Tanya Danilkovich is not tied to any single carrier. She can compare Plan G and Plan N premiums across multiple top-rated Illinois carriers simultaneously, and her professional obligation is to the client — not the insurance company.

The practical implication of this distinction is significant. Two Illinois residents of the same age and zip code who both enroll in Medigap Plan G may end up paying very different monthly premiums simply because one worked with a captive agent and the other had access to a full market comparison. That premium difference compounds every month for years. An independent broker closes that gap by design.

Таня Данілкович has been a licensed independent insurance broker for more than 15 years, holding active licenses in Illinois, Florida, and Ohio. Before founding TD Integrity Insurance Solutions, she worked as a Medicaid, SSI, and SNAP coordinator — experience that gave her an insider’s understanding of how government health programs are actually administered, not merely described. That background is directly relevant to her Medicare clients. She has seen firsthand how gaps in coverage translate into real financial hardship for real people, and she approaches every client conversation through that lens — protecting them from exposure, not maximizing a carrier commission.

At TD Integrity Insurance Solutions, the philosophy is ‘Personalized guidance you can trust.’ That is not a marketing tagline. It is a description of how every single consultation is conducted — with real numbers, real carrier comparisons, and real attention to each individual’s health picture, financial priorities, and provider relationships.

One more point worth making clearly: working with a broker costs the client nothing. Broker compensation comes from the insurance carrier after a policy is issued. The beneficiary pays nothing for the broker’s time, expertise, or access to multi-carrier quotes. There is no financial barrier to getting professional help with this decision.

This is not about being sold a plan. It is about having a licensed professional with 15+ years of real-world experience run the numbers, ask the right questions, and help you arrive at a confident, informed decision — without pressure, without jargon, and at no cost to you.

Frequently Asked Questions About Medigap Plan G vs Plan N in Illinois

What Is the Difference Between Medicare Supplement Plan G and Plan N in Illinois?

When comparing Medicare Supplement Plan G vs Plan N in Illinois, both plans cover the same core Medicare gaps — including the Part A deductible, skilled nursing facility coinsurance, and foreign travel emergency care — but they differ in two important ways. Plan G covers Part B excess charges in full and requires no copayments for covered office or ER visits after the Part B deductible. Plan N does not cover excess charges and requires copays of up to $20 for office visits and up to $50 for ER visits that do not result in hospital admission. Plan N typically carries a lower monthly premium as a result.

Is Plan G or Plan N the Better Choice for Illinois Residents in 2026?

There is no single ‘better’ plan for all Illinois residents. The right choice depends on how often you use medical care, whether your providers accept Medicare assignment, and your comfort with monthly premium costs versus variable out-of-pocket exposure. When evaluating the best Medigap plans in Illinois for 2026, people with ongoing health conditions or frequent specialist visits often find that Plan G’s comprehensive structure aligns better with their needs. Healthier, low-utilization beneficiaries whose providers accept Medicare assignment may find Plan N delivers meaningful savings. A licensed broker can model both options using current 2026 carrier rates and your specific health picture.

How Much Does Medigap Plan N Cost in Illinois?

Medigap Plan N cost in Illinois varies based on the carrier, beneficiary age, zip code, gender, and tobacco use status. Nationally, Plan N monthly premiums average approximately $121 to $219 — generally lower than Plan G’s average range of $140 to $236. However, Illinois-specific rates require a localized quote to be meaningful. Two beneficiaries of the same age in different Illinois zip codes can face notably different premiums for the exact same plan. Working with an independent broker to pull current carrier quotes is the most accurate way to understand your actual cost.

Does Medigap Plan N Cover Part B Excess Charges in Illinois?

No. Medigap Plan N does not cover Part B excess charges. These charges occur when a provider does not accept Medicare assignment and bills up to 15% above the Medicare-approved rate. Under Medigap Plan G in Illinois, those excess charges are covered in full. Under Plan N, the beneficiary is responsible for them out of pocket. Illinois has certain balance billing protections that may limit some of this exposure in practice, but the specifics depend on the provider, the service, and current state regulations — which is why discussing this with an Illinois-licensed broker is essential before selecting Plan N.

Can I Switch from Plan N to Plan G in Illinois After I’ve Enrolled?

Switching from Plan N to Plan G in Illinois after your Medigap Open Enrollment Period has closed is possible in some circumstances, but it is not guaranteed. Outside of the six-month guaranteed issue window — which begins when you are 65 or older and first enrolled in Medicare Part B — insurance carriers in Illinois may require medical underwriting. This means your health history could be reviewed, and you could be charged higher premiums or denied coverage based on pre-existing conditions. This is one of the strongest reasons to evaluate both plans carefully before your initial enrollment window closes. Learn more about how the Medigap Open Enrollment Period works at Medicare.gov.

When Is the Best Time to Enroll in a Medigap Plan in Illinois?

The optimal time to enroll in a Medigap plan in Illinois is during your Medigap Open Enrollment Period — a six-month window that begins on the first day of the month you are both 65 or older and enrolled in Medicare Part B. During this window, you have guaranteed access to any Medigap plan offered in Illinois, regardless of health history or pre-existing conditions. Once this window closes, you may face medical underwriting requirements that limit your options or increase your costs. Planning ahead — ideally three to six months before turning 65 — gives you time to compare plans, run real carrier quotes, and make a confident decision without rushing.
