What is Medicare Advantage?
Medicare Advantage is an alternative to traditional Medicare. It is also referred to as Medicare Part C and is provided by private insurers. These plans bundle together Medicare Part A (hospital insurance), Part B (medical insurance), and often Part D (prescription drug coverage), providing a comprehensive package. Most Medicare Advantage plans must cover all the services that Original Medicare covers, including inpatient and outpatient care, but they often come with additional benefits like dental, vision, and hearing coverage.
One of the key advantages of Medicare Advantage plans is the inclusion of prescription drug coverage, which means you don’t need to purchase a separate Part D plan. However, it’s important to note that these plans may have different ways of covering out-of-network care. Some plans might only cover in-network services, while others might cover a portion of out-of-network costs. Understanding these nuances can help you make an informed decision about whether Medicare Advantage is right for you.
What is Medigap?
Medigap, also known as Medicare Supplement Insurance, is designed to fill the coverage gaps left by Original Medicare. Unlike Medicare Advantage, Medigap works alongside Original Medicare, helping to cover out-of-pocket costs such as copayments, coinsurance, and deductibles. There are ten standardized types of Medigap plans available, each offering different levels of coverage, allowing beneficiaries to choose a plan that best fits their needs.
Enrollment in Medicare Part B is a requirement for purchasing a Medigap plan. Without being enrolled in Part B, you cannot obtain a Medigap policy. The best time to buy a Medigap plan is during the Medigap open enrollment period, which lasts six months starting when you are 65 or older and have Medicare Part B.
During this period, one insurance company must offer you a Medigap plan, regardless of your health status. This can be particularly beneficial for those with pre-existing conditions, as it ensures access to supplemental coverage without the risk of medical underwriting.
Comparing Costs: Premiums, Copays, and Coinsurance

When choosing between Medicare Advantage and Medigap, cost is a significant factor to consider. Both options have different cost structures, affecting your overall medical costs. Medicare Advantage plans often have lower upfront costs, with many plans offered at a $0 premium. However, it’s important to evaluate factors such as copayments, coinsurance, and hospitalization costs when considering a Medicare Advantage plan.
In contrast, most medigap plans typically come with higher monthly premiums but provide more comprehensive coverage for out-of-pocket costs and medigap premiums. Your budget and travel habits should play a crucial role in your decision-making process.
The following subsections will break down the costs associated with each type of plan, helping you understand the financial implications of your choice.
Monthly Premiums
Medicare Advantage and Medigap plans both require monthly premiums, but their pricing structures differ significantly. Medicare Advantage plans often feature lower monthly premiums compared to Medigap, with many plans offered at a $0 premium. This can make Medicare Advantage an attractive option for those looking to minimize their upfront costs.
On the other hand, purchasing a Medigap plan necessitates an additional monthly premium on top of the Medicare Part B premium. Medigap plans generally have higher monthly premiums, but this cost comes with the benefit of more predictable out-of-pocket expenses.
In summary, while Medicare Advantage plans may offer lower or even $0 premiums, Medigap plans require a separate monthly premium but provide more comprehensive coverage for out-of-pocket costs.
Out-of-Pocket Costs
When comparing Medicare Advantage and Medigap, it’s essential to consider the out-of-pocket costs associated with each plan. Medicare Advantage plans tend to have higher out-of-pocket costs, including copayments and coinsurance, compared to Medigap. This means that while the monthly premiums for Medicare Advantage may be lower, you could end up paying more in medical expenses as you receive care.
Medigap plans, on the other hand, cover many out-of-pocket costs such as inpatient hospital stay deductibles, copayments, and parts a and b coinsurance. They provide coverage for Part A coinsurance, hospital costs, and Part B coinsurance and copayments.
Overall, beneficiaries may encounter higher out-of-pocket costs with Medicare Advantage due to its copayment and coinsurance structure, compared to the protective coverage provided by Medigap.
Coverage Differences: Medical Services and Extra Benefits
The coverage provided by Medicare Advantage and Medigap plans differs significantly, particularly in terms of medical services and extra benefits. Understanding these differences is crucial for making an informed decision about your healthcare coverage. Medicare Advantage plans often provide broader coverage for medical services compared to Medigap plans, including additional benefits like dental, vision, and hearing coverage.
While Original Medicare covers basic medical services, it does not include dental care, vision care, or long-term care unless medically necessary. Medicare benefits and Medicare Advantage plans fill these gaps by offering a range of additional benefits.
The following subsections will explore the specific medical services and extra benefits provided by each type of plan.
Medical Services
Medicare Advantage plans must cover all services that Original Medicare covers, but they often include additional benefits like dental, vision, and hearing coverage. These plans also have varying out-of-pocket limits, providing beneficiaries with protection against high healthcare costs. Starting in 2025, there will be a cap of $2,000 on prescription drug costs for beneficiaries enrolled in Medicare Advantage plans.
In contrast, Medigap policies do not include prescription drug coverage, which must be obtained separately through a prescription drug plan (Part D). Medigap plans help pay for out-of-pocket costs not covered by Original Medicare, such as copayments and coinsurance, including prescription drugs.
There are ten standardized types of Medigap plans available, each offering different levels of coverage. Some plans, like Plans F and C, provided coverage for the Medicare Part B deductible if purchased before January 1, 2020.
Extra Benefits
Medicare Advantage plans often provide additional benefits beyond standard coverage, such as dental, vision, and hearing care. These extras are commonly included in Medicare Advantage plans, making them an attractive option for those seeking comprehensive healthcare coverage.
For example, many Medicare Advantage plans offer eye exams, hearing aids, and dental care as part of their extra benefits. These additional benefits provide enhanced health care options that are not available with Medigap plans.
Choosing a Medicare Advantage plan can therefore offer more extensive coverage for those seeking dental, vision, and hearing services.
Provider Networks: Access and Flexibility
One of the key differences between Medicare Advantage and Medigap is the provider network. Medicare Advantage plans typically have specific networks that limit provider choices, requiring beneficiaries to use in-network providers to minimize costs. This can impact your choice of healthcare providers and your overall flexibility in accessing care.
In contrast, Medigap plans do not involve any network restrictions, enabling beneficiaries to see any doctor or healthcare provider that accepts Medicare. This broader access can be particularly beneficial for those who travel frequently or prefer to have more flexibility in choosing their healthcare services.
In-Network vs. Out-of-Network

Medicare Advantage plans typically require beneficiaries to use in-network providers to minimize costs. This means that if you seek care outside of the plan’s network, you may face higher out-of-pocket costs or even lack coverage for certain out of network services. This network restriction can be a significant consideration, especially for those who value the freedom to choose their healthcare providers.
On the other hand, Medigap plans do not have any network restrictions, allowing beneficiaries to see any doctor or hospital that accepts Medicare. This provides greater flexibility and access to a broader range of healthcare providers. For individuals who prioritize having access to various healthcare providers without worrying about network limitations, Medigap is often the preferred choice.
