Medicare Advantage and Medicare Supplement plans are two different ways to build on Original Medicare, and choosing between them is one of the most important Medicare decisions you will make. Medicare Advantage combines your Medicare benefits into one private plan, often with lower monthly premiums but provider-network rules. Medicare Supplement plans work alongside Original Medicare to help cover out-of-pocket costs while offering broader provider flexibility.
At Cilella Insurance, we compare both options at no cost so you can choose with confidence. Based in Morgantown, West Virginia, and serving clients across 14 licensed states, we help you look beyond the advertisements and focus on the coverage, doctors, medications, and budget that matter to you.
What Is Medicare Advantage (Part C)?
Medicare Advantage, also called Part C, is an alternative way to receive your Medicare Part A and Part B benefits. Instead of getting those benefits directly through Original Medicare, you receive them through a private insurance company approved by Medicare.
Most Medicare Advantage plans include prescription drug coverage, known as Part D. Many also include added benefits that Original Medicare does not typically cover, such as routine dental, vision, hearing, fitness programs, transportation, or over-the-counter allowances. Benefits vary by plan and county.
Medicare Advantage plans often have low monthly premiums, including some plans with a $0 plan premium. However, you must continue paying your Medicare Part B premium. You will also generally pay copays, coinsurance, or deductibles when you receive care.
Most plans use a provider network. An HMO may require you to use in-network doctors and hospitals for non-emergency care, while a PPO may allow out-of-network care at a higher cost. Some services may require prior authorization before the plan will cover them.
What Is a Medicare Supplement (Medigap) Plan?
Medicare Supplement plans, often called Medigap plans, work alongside Original Medicare. You keep Original Medicare for your Part A hospital coverage and Part B medical coverage, then add a private Medigap policy to help pay certain out-of-pocket costs that Original Medicare leaves behind.
Depending on the plan letter you choose, a Medicare Supplement policy may help with Medicare deductibles, coinsurance, copayments, and other covered cost-sharing. You generally pay a separate monthly premium for your Medigap policy in addition to your Part B premium.
Medigap plans sold today do not include prescription drug coverage. If you choose Original Medicare plus a Medicare Supplement, you will usually want to enroll in a separate Part D prescription drug plan as well.
One major advantage is provider flexibility. With Original Medicare and a Medicare Supplement, you can generally see any doctor or visit any hospital nationwide that accepts Medicare. You do not need to stay within a local Medicare Advantage network for non-emergency care.
The Core Difference: Cost vs. Flexibility
The simplest way to think about this decision is that Medicare Advantage often emphasizes lower monthly premiums and added benefits, while Medicare Supplement coverage often emphasizes predictable medical costs and broader provider access.
Neither choice is automatically better. The right plan depends on what matters most to you.
Medicare Advantage may offer:
- Lower monthly plan premiums in many areas.
- Prescription drug coverage bundled into most plans.
- Extra benefits such as dental, vision, hearing, and fitness programs.
- A yearly maximum out-of-pocket limit for covered Medicare services.
- Potentially lower upfront cost when you do not need frequent medical care.
Medicare Supplement may offer:
- Broad access to doctors and hospitals that accept Medicare nationwide.
- Less concern about local provider networks for routine care.
- Lower or more predictable out-of-pocket costs for Medicare-covered services, depending on the policy.
- Fewer referral requirements and less plan-based prior authorization for Original Medicare-covered care.
- Portability for people who travel often or split time between states.
With Medicare Advantage, your monthly cost may be lower, but your share of costs can increase when you use care. With Medigap, you may pay more each month, but you may have fewer unexpected medical bills for Medicare-covered services.
When Medicare Advantage Makes Sense
Medicare Advantage can be a strong fit for someone who wants an all-in-one plan, values extra benefits, and is comfortable using a provider network. It may also appeal to people who want to keep monthly premiums as low as possible.
You may want to consider Medicare Advantage if you:
- Live in an area with a strong local provider network.
- Are comfortable confirming network status before receiving non-emergency care.
- Want prescription drug coverage included in one plan.
- Value benefits such as dental, vision, hearing, transportation, or fitness programs.
- Prefer a plan with a defined annual maximum out-of-pocket amount for covered services.
- Do not travel frequently or receive routine care in multiple states.
For clients in the Morgantown area, we encourage a careful review of the specific plan network before enrolling. If you want to continue using providers connected with WVU Medicine or Mon Health, it is important to verify that your doctors, specialists, and preferred hospitals participate in the exact Medicare Advantage plan you are considering. Network participation can change, and one carrier’s plan may not have the same network as another plan offered in the same county.
We also review your prescriptions. A Medicare Advantage plan may include Part D coverage, but drug formularies, pharmacy networks, deductibles, and copays differ from plan to plan. The right plan for your neighbor may not be the right plan for you.
When a Medicare Supplement Makes More Sense
A Medicare Supplement plan may be a better fit for someone who values provider choice, travels frequently, sees multiple specialists, or wants more predictable medical costs. It can also make sense for people who do not want their coverage tied to a local provider network.
You may want to consider Medigap if you:
- Want the freedom to see Medicare-accepting providers across the country.
- Travel regularly, spend time in another state, or have family elsewhere.
- Use specialists or hospitals outside your immediate area.
- Prefer fewer provider-network concerns for Medicare-covered care.
- Are comfortable paying a separate premium for Medigap and a separate Part D drug plan.
- Want to reduce the uncertainty of deductibles and coinsurance under Original Medicare.
Medigap is especially important to evaluate when you first become eligible for Medicare Part B. Your federal Medigap Open Enrollment Period begins when you are both 65 or older and enrolled in Part B, and it lasts six months. During that time, you generally have strong protections to buy a Medigap policy without medical underwriting.
After that period, changing to a Medicare Supplement policy may be more difficult or more expensive, depending on your health, state rules, carrier availability, and whether you qualify for a guaranteed-issue right. That does not mean you should automatically choose Medigap—but it does mean you should understand the long-term implications before choosing Medicare Advantage.
Can You Switch Between the Two?
You can make certain Medicare coverage changes during Medicare Annual Enrollment, which runs from October 15 through December 7 each year. During that period, you can generally move from Medicare Advantage back to Original Medicare or switch to another Medicare Advantage plan. Changes generally take effect January 1.
However, returning to Original Medicare does not automatically guarantee that you can buy a Medicare Supplement plan without underwriting. In many cases, you may need to answer health questions unless you are within your original Medigap Open Enrollment Period or qualify for a specific guaranteed-issue right.
There are exceptions. For example, some people who joined Medicare Advantage for the first time when they were eligible may have a limited trial right to return to Original Medicare and buy certain Medigap coverage. Certain moves, plan terminations, and other situations may also create guaranteed-issue rights.
This is why we encourage clients not to make a Medicare change based solely on a television commercial, a mailer, or a low premium. Before leaving Medigap for Medicare Advantage—or leaving Medicare Advantage for Original Medicare—we look at the full picture and discuss what coverage you can realistically obtain.
Plan Availability in West Virginia, Pennsylvania, Ohio, and Maryland
Medicare plan availability is local. Medicare Advantage plans are generally offered by county, which means options available in Monongalia County may be different from the plans available in nearby Pennsylvania or Ohio counties. Premiums, provider networks, drug formularies, dental benefits, and maximum out-of-pocket amounts can all vary by location.
Medicare Supplement plans are also priced and offered differently by state and carrier. The benefits of standardized Medigap plan letters are generally consistent, but premiums can vary substantially between insurers and locations. Comparing the same plan letter from multiple carriers can be worthwhile.
For clients in West Virginia, Pennsylvania, Ohio, and the other states where we are licensed, we review the specific plans available at your home address. If you live outside our licensed service area, we recommend working with a properly licensed professional in your state before enrolling.
How Cilella Insurance Helps You Compare
At Cilella Insurance, we do not believe Medicare decisions should be one-size-fits-all. We start by asking about your doctors, prescriptions, travel habits, health needs, preferred hospitals, budget, and comfort level with provider networks.
Then we help you compare Medicare Advantage and Medicare Supplement coverage in plain language. We explain the premium, deductibles, copays, prescription coverage, network considerations, and enrollment rules so you can make an informed decision.
We can also discuss whether Hospital Indemnity plans
may provide an additional financial cushion for someone with Medicare Advantage hospital copays. That conversation is separate from choosing your core Medicare coverage, but it can be valuable when reviewing your full protection plan.
Start with our Medicare overview, then let us help you narrow the choices based on your personal situation.
FAQ
Can I have Medicare Advantage and a Medicare Supplement plan at the same time?
No. Medicare Supplement policies are designed to work with Original Medicare, not Medicare Advantage. It is generally illegal for someone to sell you a Medigap policy if you are enrolled in Medicare Advantage.
Does Medicare Advantage include prescription drug coverage?
Most Medicare Advantage plans include Part D prescription drug coverage, but not every plan does. Always confirm whether drug coverage is included and review your medications against the plan’s formulary.
Does Medicare Supplement cover prescription drugs?
No. Medigap policies sold today do not include prescription drug coverage. Most people who choose Original Medicare and Medigap also enroll in a separate Part D plan.
Which option is less expensive?
It depends on how you define cost. Medicare Advantage may have a lower monthly premium, while Medigap may have a higher monthly premium but lower out-of-pocket costs when you receive Medicare-covered care. We help compare both monthly and potential medical costs.
Can I keep my doctor with Medicare Advantage?
Possibly, but you must verify that your doctor and hospital are in the specific plan’s network. Do not assume a provider is covered simply because they accept Medicare or participate in another plan from the same carrier.
