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 \u2014 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.<\/p>\n
If you’ve landed on this page searching for a clear breakdown of Medicare Supplement Plan G vs Plan N in Illinois<\/strong>, 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 \u2014 not insurance company marketing copy.<\/p>\n This guide was written with the expertise of \u0422\u0430\u043d\u044f \u0414\u0430\u043d\u0438\u043b\u043a\u043e\u0432\u0438\u0447<\/strong>, 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 \u2014 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.<\/p>\n 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 \u2014 without pressure and without jargon.<\/p>\n Medicare Supplement insurance \u2014 more commonly called Medigap \u2014 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.<\/p>\n Medigap plans are federally standardized<\/strong>, 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 \u2014 and this is a critical distinction \u2014 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<\/a> without comparing multiple carriers can mean overpaying for identical coverage.<\/p>\n 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<\/strong> across multiple carriers simultaneously, an independent broker can do this at no cost to the consumer \u2014 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.<\/p>\n 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.<\/p>\n Since Plan F was phased out for new Medicare enrollees in 2020, Medigap Plan G<\/strong> 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 \u2014 it covers nearly every significant gap Original Medicare leaves behind.<\/p>\n Here is what Medigap Plan G covers in plain English:<\/p>\n The one gap in Plan G:<\/strong> 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.<\/p>\n 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 \u2014 though actual Illinois rates require a localized quote to be meaningful. Understanding when your Medigap Open Enrollment Period begins<\/a> is equally important, as timing affects both your access to coverage and the premiums you’ll pay.<\/p>\n Plan N is not a lesser plan \u2014 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.<\/p>\n Here is what Medigap Plan N covers:<\/p>\n Key Difference #1 \u2014 Copayments:<\/strong> 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.<\/p>\n Key Difference #2 \u2014 Part B Excess Charges:<\/strong> 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 \u2014 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 \u2014 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.<\/p>\n Plan N does not cover<\/strong> the Part B deductible ($257 in 2025) \u2014 the same gap that exists in Plan G.<\/p>\n 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 \u2014 which effectively eliminates excess charge exposure \u2014 and are comfortable with occasional small copayments in exchange for a lower monthly premium. When comparing Medigap Plan N cost in Illinois<\/strong>, national average monthly premiums range from approximately $121 to $219, generally lower than Plan G’s range \u2014 though actual Illinois rates vary meaningfully by carrier, age, and zip code. A localized quote is essential to understanding your real savings.<\/p>\n Now that both plans have been explained individually, here is the side-by-side view across the dimensions that matter most for Illinois beneficiaries.<\/p>\nWhat Is a Medigap Plan \u2014 and Why Does It Matter for Illinois Residents?<\/h2>\n
