Navigating the world of Medicare can be complex, especially when it comes to understanding supplemental coverage options. At Dave Silver Insurance, we often encounter questions about Medigap insurance and its role in healthcare.
Let’s explore the Medigap insurance definition and how it can fill the gaps in your Medicare coverage. This guide will help you make informed decisions about your healthcare future.
What Is Medigap Insurance?
Defining Medigap Insurance
Medigap insurance, also known as Medicare Supplement Insurance, fills the “gaps” in Original Medicare coverage. It provides financial protection against out-of-pocket costs that can accumulate quickly for Medicare beneficiaries.
The Medicare Coverage Bridge
Original Medicare (Part A for hospital insurance and Part B for medical insurance) covers a significant portion of healthcare costs. However, it leaves beneficiaries responsible for deductibles, copayments, and coinsurance. Medigap is a separate policy sold by private insurance companies that works alongside Original Medicare to reduce or eliminate these expenses.
Medigap vs. Original Medicare
Unlike Original Medicare, Medigap policies are standardized across most states, offering predictable coverage regardless of location. There are currently ten standardized plans (labeled A through N), each providing a different level of coverage. This standardization allows consumers to compare policies across different insurance providers easily.
While Original Medicare is government-administered, private insurance companies offer Medigap policies. The benefits are standardized, but premiums can vary significantly between insurers. A 2023 report by the American Association for Medicare Supplement Insurance found that the average monthly premium for Medigap Plan G (one of the most popular options) was $164. However, this ranged from $140 in Washington D.C. to $236 in New York.
How Medigap Supplements Medicare
Medigap’s primary function is to cover costs that would otherwise be the beneficiary’s responsibility. For instance, most Medigap plans cover the Medicare Part A deductible. Some plans also cover the Part B deductible, although this option is no longer available for new Medicare beneficiaries as of 2020.
Medigap doesn’t replace Original Medicare; it works in tandem with it. Medicare pays its share of approved costs first, and then the Medigap policy pays its share. This coordination often results in significantly reduced (or even eliminated) out-of-pocket costs for beneficiaries.
Medigap Adoption Rates
The Kaiser Family Foundation reports that in 2022, 12.5 million Medicare beneficiaries (about 42% of those with traditional Medicare) had a Medigap policy. This high adoption rate underscores the value many find in this supplemental coverage.

Understanding the nuances of Medigap insurance allows you to make an informed decision about whether this type of coverage aligns with your healthcare needs and financial situation. As we move forward, let’s explore the various types of Medigap plans available and how they differ in coverage and benefits.
Medigap Plans Explained
The Alphabet Soup of Medigap Plans
Medigap insurance offers a range of standardized plans, each designed to cover different aspects of Medicare’s out-of-pocket costs. These plans, labeled A through N, provide varying levels of coverage to suit different needs and budgets.
The Centers for Medicare & Medicaid Services (CMS) has standardized Medigap plans across most states. In Massachusetts, Minnesota, and Wisconsin, Medigap policies are standardized in a different way.
Currently, ten standardized Medigap plans exist: A, B, C, D, F, G, K, L, M, and N. Each plan covers a different set of benefits, with some offering more comprehensive coverage than others. It’s important to note that as of January 1, 2020, Plans C and F are no longer available to newly eligible Medicare beneficiaries.
Popular Medigap Plans and Their Coverage
Recent data from the American Association for Medicare Supplement Insurance reveals that Plan G has become the most popular Medigap plan, comprising 39% of policyholders in 2023. Plan G covers all out-of-pocket costs except for the Medicare Part B deductible.
The second most popular plan is Plan F (accounting for 36% of policyholders). However, Plan F is only available to beneficiaries who were eligible for Medicare before 2020. Plan F offers the most comprehensive coverage, including the Part B deductible.

Plan N has also gained popularity, offering lower premiums in exchange for some cost-sharing. With Plan N, beneficiaries pay up to $20 for some office visits and up to $50 for emergency room visits that don’t result in inpatient admission.
Comparing Medigap Plan Benefits
When comparing Medigap plans, consider your healthcare needs and budget. Here are some key differences:
- Part A Deductible: All plans except A cover this deductible.
- Part B Excess Charges: Only Plans F and G cover these charges.
- Foreign Travel Emergency: Plans C, D, F, G, M, and N cover 80% of foreign travel emergency costs (up to plan limits).
- Out-of-Pocket Limits: Only Plans K and L have out-of-pocket limits ($6,940 and $3,470 respectively in 2023).
The Kaiser Family Foundation reports that the average monthly premium for Medigap policyholders in 2023 was $217 (equating to $2,604 annually). However, these premiums can vary significantly based on factors such as age, location, and the specific plan chosen.
Choosing the Right Medigap Plan
Selecting the appropriate Medigap plan requires careful consideration of your health needs and financial situation. It’s essential to weigh the benefits of each plan against its cost. While a plan with higher premiums might offer more comprehensive coverage, a plan with lower premiums could be more suitable if you have fewer health concerns.
Consider your current health status, anticipated medical needs, and budget when evaluating Medigap plans. It’s also wise to review your choice periodically, as your health needs may change over time.
As we move forward, let’s explore the eligibility requirements and enrollment periods for Medigap insurance, which play a significant role in securing the best coverage for your needs.
Who Can Get Medigap Insurance
Eligibility Basics
Medigap insurance eligibility hinges on enrollment in both Medicare Part A and Part B. This requirement forms the foundation of qualification. In 2022, 12.5 million, or four in 10 (42%) people in traditional Medicare had a Medigap policy.

Age plays a significant role in Medigap eligibility. Most people become eligible at 65, but some states offer Medigap policies to those under 65 with disabilities or specific diseases. These options can be limited and potentially more expensive.
The Open Enrollment Period
The Medigap Open Enrollment Period presents the best opportunity to enroll in a Medigap policy. This six-month window starts on the first day of the month you turn 65 or older and enroll in Medicare Part B. During this period, you have guaranteed issue rights, which means insurance companies must sell you a Medigap policy without underwriting or health screening.
The National Association of Insurance Commissioners emphasizes this period’s importance, as it provides the most options at the best prices. Failure to enroll during this window can result in higher premiums or even denial of coverage based on health status.
Enrollment Outside the Open Period
If you miss your Open Enrollment Period, you can still apply for Medigap, but the process becomes more challenging. Insurance companies can use medical underwriting to decide whether to accept your application and how much to charge you. This can lead to higher premiums or even denial of coverage based on pre-existing conditions.
Some states have implemented additional protections. For example, New York and Connecticut have continuous open enrollment, allowing residents to purchase Medigap policies year-round without underwriting. It’s important to check your state’s specific rules and regulations.
Special Circumstances
In certain situations, you might have guaranteed issue rights outside of your Open Enrollment Period. These include losing coverage from a Medicare Advantage plan or employer-sponsored insurance. The Medicare Rights Center advises beneficiaries to keep documentation of their coverage history, as this can prove vital when applying for Medigap outside the standard enrollment period.
Expert Guidance
Understanding these eligibility and enrollment rules proves vital for securing the right Medigap coverage at the right time. Whether you approach 65 or consider a change in your Medicare coverage, plan ahead and explore your options thoroughly. Consulting with a knowledgeable insurance professional (such as those at Dave Silver Insurance) can help you navigate these complex decisions and ensure you get the coverage you need when you need it.
