Medicare covers a lot, but not everything. You’ll face significant out-of-pocket costs for deductibles, copayments, and services Original Medicare doesn’t pay for.
Medigap coverage is offered to Medicare beneficiaries by private insurance companies to fill these gaps. At Dave Silver Insurance, we help beneficiaries understand their options and find the right plan for their situation.
What Medigap Actually Covers and Why It Matters
Original Medicare leaves you exposed to substantial costs that many beneficiaries underestimate. In 2026, the Part B deductible is $283 before Medicare pays anything. After that, you’ll owe 20% coinsurance on most services, and there’s no annual cap on what you can spend out of pocket.
A single hospitalization or extended illness can quickly drain your savings. According to data from the Medicare Current Beneficiary Survey in 2023, 13% of traditional Medicare beneficiaries had no supplemental coverage at all, leaving them vulnerable to unexpected medical bills.
Medigap insurance fills these gaps by covering deductibles, copayments, and coinsurance that Original Medicare doesn’t pay. Private insurers sell these standardized plans so that Plan G offers the same core benefits regardless of which company issues it. This standardization means you can compare plans based purely on price and optional features rather than worrying about different benefit structures from different insurers.
Why Plan G Dominates for New Enrollees
If you turned 65 after January 1, 2020, you cannot buy Plan F or Plan C, the historically most comprehensive options. Plan G has become the practical choice for new beneficiaries because it covers everything except the Part B deductible. Since most people spend far more than that deductible amount on healthcare annually, this gap is manageable compared to the protection you gain. According to enrollment trends tracked by the Centers for Medicare and Medicaid Services, Plan G enrollment grew from 2.3 million beneficiaries in 2018 to 4.5 million by 2021.
Plan N represents another solid option if you want lower premiums; it covers most costs but requires small copayments for certain office visits and emergency room visits. The trade-off is straightforward: you pay less monthly but accept modest out-of-pocket costs when you receive care.
Three Critical Mistakes to Avoid
Many people wrongly assume Medigap covers prescription drugs, hospital stays abroad, or works alongside Medicare Advantage plans. It does none of these. You need a separate Part D plan for medications. Foreign travel coverage exists only on certain Medigap plans and typically covers 80% of emergency care up to plan limits.
You cannot hold both Medigap and Medicare Advantage simultaneously; you must choose one path or the other.
Waiting too long to enroll creates serious problems. The six-month Open Enrollment Period after you turn 65 and enroll in Part B offers guaranteed issue protection, meaning insurers cannot deny you coverage or charge more based on health conditions. Miss this window, and you face medical underwriting that can result in higher premiums or outright rejection.
Ignoring annual plan reviews costs you money. Medigap premiums and plan availability change yearly, and what made sense last year might not be your best option today. Your circumstances shift, new plans enter the market, and existing plans adjust their rates. Reviewing your coverage annually helps you stay aligned with your actual healthcare needs and budget.
How to Move Forward With Confidence
Understanding what Medigap covers is only half the battle. The next step involves comparing the specific plans available in your area and determining which one matches your health profile and financial situation. Each plan type offers different combinations of coverage, and your choice depends on factors like how much you travel internationally, whether you prefer lower premiums or lower out-of-pocket costs, and which insurers operate in your state.
Comparing Medigap Plans to Find Your Best Option
Plan Types and Coverage Levels
The 10 standardized Medigap plans available today split into two categories: comprehensive coverage with higher premiums, and limited coverage with lower monthly costs. Plans A, B, D, G, M, and N represent the most commonly offered options, though Plans K and L exist for beneficiaries who prefer lower premiums in exchange for annual out-of-pocket spending limits. Plan G covers nearly everything except the Part B deductible of $283 in 2026, making it the de facto standard for new enrollees. Plan N costs less monthly but requires you to pay $20 copays for some office visits and up to $50 for emergency room visits that don’t result in admission.
The difference between Plan G and Plan N typically amounts to $30 to $60 per month in premiums, but Plan N could cost you more annually if you visit doctors frequently or use the emergency room. According to the Medicare Current Beneficiary Survey, beneficiaries with Medigap tend to have higher incomes and education levels, suggesting they prioritize predictable healthcare costs over premium minimization. Plan G enrollment data from the Centers for Medicare and Medicaid Services shows it captured 4.5 million beneficiaries by 2021, up from 2.3 million in 2018, confirming its status as the market leader for new-to-Medicare buyers.
Lower-Premium Options With Spending Caps
Plans K and L include annual out-of-pocket limits of $8,000 and $4,000 respectively in 2026, after which the plan covers 100 percent of remaining covered services. These plans appeal to people confident they won’t exceed the spending cap and want the lowest possible monthly payment. High-deductible versions of Plans F and G exist in some states, requiring you to pay $2,950 out of pocket before coverage begins, but these versions cost substantially less monthly if you rarely use healthcare.
How to Compare Plans Across Insurers
Medicare Plan Finder on Medicare.gov allows you to enter your ZIP code and see which plans each carrier offers locally. This tool shows you monthly premiums side by side, but it doesn’t display the actual copays or coinsurance amounts, so you must cross-reference the official benefit comparison chart on Medicare.gov to understand what you’ll actually pay at the doctor’s office. Request written quotes directly from at least three insurers in your state because premium differences for identical plans can reach $50 to $100 monthly depending on the company and your age.
Some insurers use community rating, charging everyone the same regardless of age, while others use attained-age rating, increasing your premium annually as you get older. State insurance departments provide comparative premium information for your area, and some states like New York regulate Medigap pricing more strictly than federal law requires.
Calculate Your True Annual Cost
Calculate your total annual cost by multiplying the monthly premium by 12 and adding estimated out-of-pocket expenses based on your current medications and doctor visits; this reveals whether Plan G’s higher premium actually saves you money compared to Plan N. Many beneficiaries focus only on the monthly premium and ignore potential out-of-pocket costs, then face surprise bills when they need care. Try to estimate your healthcare usage realistically rather than assuming you’ll stay healthy and rarely visit doctors.
The next step involves understanding when you can enroll in Medigap and what happens if you miss the critical enrollment windows that protect you from medical underwriting and premium penalties.
When to Enroll and Where to Buy Medigap
Your Golden Window: The Open Enrollment Period
The six-month Open Enrollment Period after you turn 65 and enroll in Part B offers protection you cannot get any other time. During this period, insurers must sell you any Medigap plan they offer without medical underwriting, regardless of pre-existing conditions, and they cannot charge higher premiums based on your health status. This protection expires the moment the window closes. Miss it, and you face medical underwriting that can result in denial of coverage or premiums 25% to 50% higher than you would have paid during enrollment. The Centers for Medicare and Medicaid Services tracks these enrollment windows strictly, and insurers follow federal rules precisely. If you turn 65 in March, your Open Enrollment Period runs from March through August. Mark this on your calendar and act within these months because the financial consequences of waiting are substantial and permanent.
Three Ways to Purchase Medigap Coverage
You have three paths to purchase Medigap: direct from an insurance company website, through a licensed insurance agent, or through a broker representing multiple carriers. Buying direct from an insurer’s website works if you know exactly which company and plan you want, but most people benefit from working with a licensed agent who can compare multiple carriers simultaneously and explain plan differences without bias. Agents must be licensed in your state to sell Medigap, so verify this before sharing personal information.
Request written quotes from at least three different insurers because the same plan from different companies can cost $40 to $100 monthly apart depending on their rating methodology and local market.
Understanding Premium Rating Methods
Some insurers use community rating where everyone pays the same price regardless of age, while others use attained-age rating where your premium increases annually as you grow older. Your state insurance department website lists approved Medigap carriers and often publishes comparative premium tables showing what different plans cost from each insurer in your ZIP code. Availability varies dramatically by location; not every plan is sold everywhere, and some states like Massachusetts, Minnesota, and Wisconsin use their own plan designs instead of the federal standardized plans. Enter your ZIP code into Medicare Plan Finder on Medicare.gov to see which specific plans each carrier offers in your area and their monthly premiums. This tool shows pricing but requires you to cross-reference the official benefit chart to understand actual copayments and coinsurance amounts.
Special Circumstances That Protect Your Enrollment Rights
If you have employer or union health coverage, verify whether that coverage qualifies as credible coverage before assuming you need Medigap, because losing employer coverage triggers guaranteed issue rights outside the standard Open Enrollment Period. Special circumstances like moving to a new state or losing other credible coverage also create guaranteed issue windows lasting 63 days, giving you protection even if you miss your initial six-month period. These exceptions exist to prevent people from facing permanent penalties when life circumstances change beyond their control.
Final Thoughts
Choosing the right Medigap plan requires you to make three core decisions: which plan type matches your healthcare needs, when to enroll to avoid penalties, and which insurer offers the best value in your area. Plan G dominates for new beneficiaries because it covers nearly everything except the Part B deductible, while Plan N appeals to people who prioritize lower monthly premiums over predictable out-of-pocket costs. Your choice depends on realistic estimates of your annual healthcare usage, not assumptions about staying healthy.
The six-month Open Enrollment Period after you turn 65 and enroll in Part B protects you from medical underwriting and permanent premium increases that can cost thousands of dollars over time. Start your search by entering your ZIP code into Medicare Plan Finder to see which plans each carrier offers locally and their monthly premiums. Request written quotes from at least three insurers because identical plans vary by $40 to $100 monthly depending on the company and rating method.
