Turning 65 marks a significant milestone, bringing with it the opportunity to enroll in Medicare, the federal health insurance program. For most, this means a choice between two primary pathways to coverage: Medicare Advantage (Part C) or Original Medicare supplemented by a Medigap policy. This decision is one of the most crucial you’ll make for your health and financial future, as it impacts everything from your monthly costs to your choice of doctors and hospitals.
At EIMA Health Insurance, we understand the complexity and weight of this choice. With our corporate office in Dallas, TX, and a dedicated team serving Texans as well as residents in New Jersey, Kentucky, Maryland, and Virginia, we are committed to providing clear, unbiased guidance. While the core rules of Medicare are federal, the plans and their costs vary significantly from state to state. We are here to help you navigate these state-specific nuances to find the plan that aligns perfectly with your lifestyle and healthcare needs.
Understanding the Two Pathways
Before diving into the details, it’s essential to understand the fundamental difference between these two options.
- Medicare Advantage (Part C): This is an all-in-one alternative to Original Medicare. You enroll in a plan offered by a private company that has been approved by Medicare. These plans bundle your Part A (hospital) and Part B (medical) coverage, and most include Part D (prescription drug coverage). Many Medicare Advantage plans also offer extra benefits not covered by Original Medicare, such as routine dental, vision, and hearing care, as well as gym memberships.
- Medigap (Medicare Supplement Insurance): This is supplemental coverage you purchase from a private company to work alongside your Original Medicare (Part A and Part B). A Medigap policy helps pay for the “gaps” in Original Medicare—the out-of-pocket costs like copayments, coinsurance, and deductibles. You must have Original Medicare to purchase a Medigap policy, and you will also need to buy a separate Part D plan for prescription drugs.
You cannot have both a Medicare Advantage plan and a Medigap policy at the same time.
A Deeper Dive: Key Differences to Consider
Choosing between these two pathways involves weighing several key factors: cost, flexibility, and coverage.
1. Cost and Financial Predictability
This is often the most significant factor for many seniors.
- Medicare Advantage: These plans are known for their low monthly premiums, with many “zero-premium” plans available, especially in highly populated areas like Dallas, TX, or Northern Virginia. However, this doesn’t mean you pay nothing. You will have a copayment or coinsurance for almost every service you receive (e.g., a $20 copay for a doctor’s visit, a $250 copay for a hospital stay). The good news is that all Medicare Advantage plans have an annual out-of-pocket maximum (OOMP). Once you hit that limit, the plan covers 100% of your Medicare-covered services for the rest of the year, providing a predictable ceiling on your spending.
- Medigap: Medigap policies have a higher monthly premium, which you pay in addition to your Part B premium. While these premiums can be substantial (average premiums for popular plans like Plan F and Plan G in Texas can range from $180 to $300+ per month), the trade-off is that you have very few, if any, out-of-pocket costs for covered services. A Medigap policy essentially buys you peace of mind, as it covers most or all of your deductibles and copayments, making your financial responsibility highly predictable.
2. Provider Network and Flexibility
Your freedom to choose a doctor or hospital is a major differentiator.
- Medicare Advantage: Most MA plans operate with a provider network (HMO or PPO). With an HMO, you must stay within the network for all non-emergency care and may need a referral to see a specialist. With a PPO, you have more flexibility to see out-of-network providers, but at a higher cost. This can be a concern for those who travel frequently or want to see a specific specialist who may not be in their plan’s network.
- Medigap: If you have Original Medicare and a Medigap policy, you can see any doctor, hospital, or provider in the United States that accepts Medicare. No referrals are needed to see a specialist, and you can travel and receive care without worrying about network restrictions. This is a huge advantage for people who travel or have a winter home in another state.
3. Extra Benefits and Services
This is where Medicare Advantage plans often shine.
- Medicare Advantage: As part of their bundled approach, MA plans often include benefits that Original Medicare and Medigap do not, such as:
- Routine dental, vision, and hearing exams and coverage
- Health and wellness programs (e.g., gym memberships)
- Prescription drug coverage (Part D)
- Medigap: Medigap policies are standardized and only cover the gaps in Original Medicare. They do not cover extra benefits. You will need to purchase a separate Part D plan for prescription drug coverage.
Statistics and Trends: A State-by-State Look
Enrollment in these plans varies significantly by state, often reflecting regional preferences and the number of plans available.
- Texas: As of 2024, Texas had a high percentage of Medicare beneficiaries enrolled in Medicare Advantage plans. The state’s large, urban populations (like in the DFW Metroplex) are a perfect market for the competitive MA plans, many of which offer low or $0 premiums.
- Virginia: MA enrollment in Virginia is also substantial and growing, as more plans become available with appealing extra benefits.
- Kentucky & Maryland: Both of these states have seen a higher-than-average enrollment in Medicare Advantage in recent years, with a significant portion of beneficiaries choosing these plans for their bundled benefits and low premiums.
- New Jersey: Medigap enrollment in New Jersey is higher than the national average, suggesting a strong preference for the flexibility and broad provider access that comes with a Medigap policy.

Frequently Asked Questions
What is the Medicare Initial Enrollment Period, and why is it so important?
The Initial Enrollment Period (IEP) is a 7-month window that begins three months before you turn 65, includes the month you turn 65, and ends three months after. This is the best time to enroll in Medicare Part A and B. It is also the only time you are guaranteed the right to buy any Medigap policy sold in your state without a health-based underwriting check. If you miss this window and try to buy a Medigap plan later, you may be denied coverage or charged higher premiums based on pre-existing conditions.
Can I switch between Medicare Advantage and Medigap?
Yes, you can switch, but with a major caveat. You can switch between plans during the annual Medicare Open Enrollment Period (October 15 to December 7). However, if you are switching from a Medicare Advantage plan to Original Medicare with a Medigap policy, you may not have a “guaranteed issue right” to buy a Medigap plan. This means a Medigap insurer can review your health history and deny you coverage. This is a crucial point that should be discussed with a licensed agent before making any changes.
What if I have a Medicare Advantage plan and want to see a doctor outside of my network?
It depends on your plan type. If you have an HMO plan, non-emergency care outside the network will not be covered at all. If you have a PPO plan, you can see out-of-network providers, but you will pay a higher coinsurance or copay.
Is it true that all Medigap plans are the same?
Yes. Medigap policies are standardized by the government. A Plan G from one insurance company will offer the exact same coverage as a Plan G from another company. The only difference will be the monthly premium and the level of customer service. This standardization makes it easy to shop for the lowest premium for the plan you want.
Let EIMA Health Insurance Be Your Guide
The choice between Medicare Advantage and a Medigap policy is highly personal and depends on your health, lifestyle, and financial situation. There is no single “best” option. A Medicare Advantage plan with a low premium and extra benefits might be perfect for a healthy person who is budget-conscious and wants everything bundled into one plan. A Medigap policy might be the better choice for someone with chronic health conditions who values the freedom to see any doctor and wants minimal out-of-pocket costs.
