Understanding Medigap: Filling the Gaps in Original Medicare
Medicare Supplement Insurance, commonly known as Medigap, is a form of private insurance that helps cover certain health care costs not paid by Original Medicare. These gaps can include deductibles, copayments, and coinsurance, which can add up quickly for those who need regular care or face serious health conditions. Because Original Medicare doesnât cover everything, many beneficiaries find themselves responsible for significant out-of-pocket expenses unless they have additional coverage.
Medigap steps in to relieve these financial pressures, but it’s important to know what it does not cover. Medigap plans do not provide prescription drug coverage, dental, vision, or hearing care. For drugs, youâll need a separate Part D planâlearn more about this in our guide to What is Medicare Part D?.
Another distinction to remember is the difference between Medigap and Medicare Advantage. Medigap works as a supplement to Original Medicare, helping pay what Medicare does not. Medicare Advantage, on the other hand, is an alternative to Original Medicare that bundles coverage (often including drug, dental, and vision) into one plan but usually with network restrictions. Medigap focuses strictly on filling the cost-sharing gaps in Parts A and B, not switching your Medicare coverage altogether.
Standardized Medicare Supplement Plans: What Are Your Options?
Most states offer ten standardized Medigap plans, labeled A through N. While the plansâ benefits are standardizedâmeaning a Plan G from one insurer offers identical coverage to anotherâs Plan Gâthere are notable exceptions in Massachusetts, Minnesota, and Wisconsin, where plans are customized.
Here is an unordered list of whatâs important to know about these standard plans:
- Plans are named A, B, C, D, F, G, K, L, M, and N.
- Each plan offers the same basic benefits no matter the insurer.
- Premiums vary by insurance company and location, but benefits do not.
- Some benefits, like foreign travel emergency coverage, are included only in certain plans.
State-specific choices mean you may encounter different options depending on where you live. However, the core advantages of Medigap consistencyâpredictable benefits and easy comparisonâremain strong across most of the country. Always verify whatâs available in your state before deciding.
Deep Dive into Popular Medigap Plans: Features and Benefits
Three Medigap plansâF, G, and Nâstand out for their popularity and the unique ways they address Medicareâs coverage gaps. Letâs look at how each one works, particularly in 2025:
Plan F: Comprehensive Coverage for Pre-2020 Enrollees
Plan F eliminates almost all out-of-pocket costs for covered Medicare services, making it extremely attractive for those who qualified before January 1, 2020. This plan covers the Part B deductible, coinsurance, excess charges, and more. If you became eligible after that date, Plan F is not available, but you may have other solid options.
Plan G: The Top Choice for New Enrollees
Plan G is the most comprehensive Medigap plan available to most new beneficiaries. It covers everything Plan F does except the annual Part B deductible. For 2025, this deductible remains small compared to the potential savings on coinsurance and copayments that Plan G enables. Many people find Plan G offers excellent value, especially if maximizing financial predictability is a priority.
Plan N: Cost-Saving with Some Copayments
Plan N appeals to healthier seniors or those who want lower premiums. While it covers most of the same benefits as Plan G, it requires copayments for office visits (up to $20) and emergency room visits (up to $50), and it doesnât cover Part B excess charges. This tradeoff can result in noticeably lower monthly premiums.
High Deductible Plans F and G: The $2,870 Deductible in 2025
For those comfortable with a larger upfront deductible in return for lower premiums, High Deductible Plan G (and F, for those eligible) might be a solid choice. In 2025, the annual deductible is $2,870, meaning coverage starts only after you have spent this amount out-of-pocket. For people in good health, these plans provide significant savings if expensive claims are unlikely.
Out-of-Pocket Limits in Plans K and L
Unlike other Medigap plans, K and L come with annual out-of-pocket limitsâ$7,220 (K) and $3,610 (L) in 2025. After you reach these limits, the plan covers 100% of remaining costs for covered services within the year. This feature can provide valuable peace of mind for beneficiaries who want a ceiling on annual expenses while accepting more cost-sharing upfront.
Recent Changes and Updates Impacting Medigap Enrollment and Coverage (2024â2025)
Plan F and Plan C Availability
As of 2020, Medigap Plans F and C are not available to people newly eligible for Medicare. These plans are still available to those who qualified before January 1, 2020, providing a comprehensive option for long-time Medicare beneficiaries. Everyone else will want to consider plans like G, N, or other choices.
Updated Deductible Amounts and Out-of-Pocket Limits for 2025
For 2025, the High Deductible Plan F and Plan G require a $2,870 deductible before coverage begins. Plans K and L have their annual spending limits set at $7,220 and $3,610, respectively. These changes are essential when comparing expected costs for 2025 and should influence your decision-making.
Standardization and Premium Variation
Even as these plans remain standardized, premiums can vary widely between insurers, geographies, and age brackets. Make sure you compare thoroughly, focusing on both current costs and the likelihood of premium increases in future years.
State-Level Updates to Watch For
States may make their own adjustments to Medigap rulesâespecially Massachusetts, Minnesota, and Wisconsinâso itâs a good idea to review local provisions each year. Your state insurance department or Medicare office can provide up-to-date details.
Choosing Plans in 2025 and Beyond
With new plan restrictions and annual updates, itâs essential to revisit your plan options every year or when your health circumstances change. Consider checking your eligibility and whether new choices could provide better value or security as your needs evolve.
Cost Factors: Premiums, Deductibles, and Additional Expenses to Consider
Evaluating Medigap isnât just about monthly premiumsâitâs about understanding all potential costs and how they can impact your budget over time.
- Plan Type: More comprehensive plans (like G and pre-2020 F) generally have the highest premiums.
- Location: Premiums can vary greatly between states and even counties.
- Age & Insurer: Some insurers use attained-age, issue-age, or community rating to set prices. This impacts how your premium changes over the years.
- Deductibles: Plans with high deductibles have lower premiums but higher upfront costs before coverage kicks in.
- Out-of-Pocket Costs: Even with Medigap, you might face other expenses, like the Part B deductible (unless you have Plan F and were eligible pre-2020), copayments, or costs for services not covered by Medicare/Medigap.
For reference, the typical premium for Plan G is about $150 per month in 2025, but local rates may be higher or lower. Budgeting for the full range of expensesâincluding possible rate increasesâis vital for long-term financial security.
When comparing costs, think about total expenses versus benefits. A higher premium plan may save you money if you use frequent medical services, while a lower cost plan may be a better fit if you expect low health care utilization. For payment convenience, you might consider using options like Medicare Easy Pay to ensure continuous, hassle-free coverage.
Enrollment Strategies to Maximize Benefits and Minimize Costs
The timing of your Medigap enrollment can dramatically impact your options and your wallet. Hereâs how to make the most of your opportunities:
Medigap Open Enrollment Period
The best time to buy Medigap is during your six-month Medigap Open Enrollment Period, which starts the month you are both 65 or older and enrolled in Part B. During this window, you have guaranteed issue rights, which means insurance companies can’t deny coverage or charge higher premiums due to your health status.
Enrolling Outside the Open Enrollment Period
If you wait past this period, insurers may require medical underwriting. This can result in higher premiums or denial of coverage if you have health issues. To understand the importance of Medicare Part Bâs role, visit What Is Medicare Part B?.
Switching Medigap Plans
Switching Medigap plans after youâre enrolled is possible, but may also require underwriting unless you qualify for special state protections or guaranteed issue scenarios (like losing other coverage). Before deciding, check your eligibility for these rights in your state.
Tips for Timing Your Purchase
Plan carefully based on your Medicare Part B start date, health status, and budget. Shopping during your Open Enrollment Period is almost always your best bet. If you need help or want to talk directly with experts, see our resources on the phone number for Medicare or other support lines.
Addressing Coverage Limitations: What Medigap Does Not Cover
Medigap plans, while filling many gaps, still leave important services uncovered. These include:
- Prescription drugs: You must enroll in a separate Part D plan.
- Routine dental, vision, and hearing care: Usually need to purchase standalone plans or seek out Medicare Advantage if these are priorities.
- Foreign travel emergency: Only available on certain plans (F, G, N), and only up to 80% of approved costs with a lifetime limit.
To meet these needs, consider bundling Medigap with standalone policies for dental or vision, and absolutely remember to add prescription drug coverage via a Part D plan. You can always find more information about supplementing your Medigap plan by speaking to a Connex Medicare advisor.
Real-Life Scenarios: Case Studies Illustrating Medigap Plan Choices
Case Study 1: Retiree with Chronic Conditions Chooses Plan G
John is a retiree with diabetes and a heart condition, so he anticipates regular outpatient visits, tests, and procedures. By enrolling in Plan G, he pays about $150 monthly and the Medicare Part B deductible, but enjoys almost complete coverage for all other Medicare-approved services. The predictability of expenses helps him budget and avoid surprise bills.
Case Study 2: Healthy Individual Opts for Plan N to Save on Premiums
Susan is 68 and in excellent health, with rare doctor visits. She chooses Plan N because its lower monthly premium fits her budget, and sheâs comfortable with the occasional $20 copayment for a doctor visit. Over the year, her total costs remain low, reflecting her limited use of health services.
Case Study 3: Pre-2020 Enrollee Leverages Plan F
Mary became eligible for Medicare in 2019 and signed up for Plan F. She never pays a bill for covered servicesâno copays, coinsurance, or deductibles. This has simplified her financial planning and provided great peace of mind, particularly as her medical needs have grown over time.
These real-world examples illustrate how different Medigap choices suit varying health profiles and risk tolerances.

Frequently Asked Questions About Medicare Supplement Plans
What are the main differences between Medigap Plan F and Plan G?
Plan F covers everything that Plan G does, but it also pays the Medicare Part B deductible. Due to 2020 rule changes, only people who became eligible for Medicare before that year can enroll in Plan F. Plan G is nearly identical, minus coverage for the Part B deductible, making it the top option for new enrollees.
How do I choose the right Medigap plan for my needs?
Start with your health care needs and budget. If you expect frequent visits and want maximum predictability, look at Plan G (or F, if eligible). If you prefer lower premiums and can afford some copayments, Plan N may be right for you. Consider your risk tolerance, future needs, and compare plans carefully.
Are there any additional costs associated with Medigap plans?
Yes, you may still have to pay your Medicare Part B premium, potential Part B deductible (if not covered by your plan), and copayments or excess charges with some plans. Medigap plans also do not cover prescription drugs, dental, vision, or hearing services.
Can I switch Medigap plans after enrollment?
You can apply to switch plans at any time, but after your Medigap Open Enrollment Period insurers may require health underwriting. Some states offer extra switching rights, so always check your local rules before making changes.
What are the most popular Medigap plans and why?
Plan G is most popular for new enrollees because it covers nearly all costs except the modest Part B deductible. Plan F remains popular for those eligible before 2020 due to its full coverage appeal. Plan N is increasingly chosen by healthy individuals seeking lower premiums and minimal cost-sharing.
