When you first enroll in Medicare, one of the biggest decisions is how you want to receive your coverage. Many people compare Medicare Supplement insurance, also called Medigap, with Medicare Advantage, also called Part C.
These choices can both help with health care costs, but they work in very different ways. The best fit often depends on your budget, doctors, prescriptions, travel habits, and comfort level with out-of-pocket costs.
Understanding the basic differences before you enroll can help you make a more confident decision.
What is Medicare Supplement insurance?
Medicare Supplement insurance is private insurance that works alongside Original Medicare, which includes Part A for hospital care and Part B for medical care.
Original Medicare pays its share of covered services first. Your Medicare Supplement plan may then help pay some or all of Medicare’s remaining approved costs, such as deductibles, copayments, and coinsurance. The exact benefits depend on the plan letter you choose and the rules in your state.
For example, many people consider Plan G because it can help with most Medicare-approved out-of-pocket costs after you meet the annual Part B deductible. Not everyone needs the same plan, however.
Medicare Supplement plans generally let you see any doctor or hospital in the United States that accepts Medicare. In most cases, you do not need referrals to see specialists.
What is Medicare Advantage?
Medicare Advantage is another way to receive your Medicare benefits. Instead of getting Part A and Part B directly through Original Medicare, you enroll in a private insurance plan approved to provide Medicare coverage.
Medicare Advantage plans must cover all medically necessary Part A and Part B services that Original Medicare covers, except hospice care, which is generally still covered by Original Medicare. Many plans may also include prescription drug coverage, dental, vision, hearing, fitness benefits, or other extras.
Most Medicare Advantage plans use provider networks. Depending on the plan type, you may need to use certain doctors, hospitals, pharmacies, or specialists to receive the lowest costs. Some plans require referrals for specialist care, while others may not.
How do Medicare Supplement and Medicare Advantage differ?
You generally choose one path or the other. You cannot use a Medicare Supplement plan to pay the cost-sharing of a Medicare Advantage plan.
- Medicare Supplement: You keep Original Medicare and add a separate Medigap policy.
- Medicare Advantage: You receive your Part A and Part B benefits through a private plan.
- Doctor choice: Medicare Supplement plans generally offer broad access to Medicare-participating providers nationwide. Medicare Advantage plans often use local or regional provider networks.
- Prescription drugs: Medicare Supplement plans usually do not include Part D drug coverage, so you may want to enroll in a separate Part D plan. Many Medicare Advantage plans include drug coverage.
- Out-of-pocket structure: Medicare Supplement plans can make many covered medical costs more predictable. Medicare Advantage plans have annual limits on Part A and Part B out-of-pocket costs, but you may pay copayments or coinsurance as you use services.
- Extra benefits: Medicare Advantage plans may offer benefits not usually covered by Original Medicare, such as routine dental, vision, or hearing services. Benefits and limits vary by plan and area.
Which choice gives you more freedom to choose doctors?
For many people, Medicare Supplement coverage offers more flexibility. With Original Medicare and a Medicare Supplement plan, you can generally see any provider nationwide who accepts Medicare. This may be especially important if you travel often, live in more than one state during the year, or want the option to see specialists at major medical centers.
Medicare Advantage plans can also be a good choice for people who are comfortable using a provider network. An HMO may focus on in-network care except in emergencies, while a PPO may offer some out-of-network coverage at a higher cost. Network rules can vary by plan, so it is wise to check whether your doctors and hospitals participate before enrolling.
How do costs work with each option?
With a Medicare Supplement plan, you generally continue paying your Part B premium plus a separate monthly premium for the supplement policy. You may also pay a separate premium for a Part D prescription drug plan. In return, your share of approved medical costs may be easier to anticipate, depending on the Medigap plan you select.
With Medicare Advantage, you still pay your Part B premium. Some plans may have an additional plan premium, while others may not. You can also have copayments, coinsurance, deductibles, and pharmacy costs when you receive care. Each plan has its own rules and annual out-of-pocket maximum for covered Part A and Part B services.
It is helpful to look beyond the monthly premium alone. Consider how often you visit doctors, whether you expect procedures or therapy, which medications you take, and how you would feel about paying costs as you use care.
When can you enroll in a Medicare Supplement plan?
Your best time to buy a Medicare Supplement policy is often your Medigap Open Enrollment Period. This six-month period begins when you are at least 65 and enrolled in Part B. During this window, insurance companies generally cannot deny you a policy or charge more because of health conditions, subject to state rules.
After that period, you may be able to apply for a Medicare Supplement plan, but medical underwriting may apply in many states. That means the insurance company can review your health history and may decide whether to accept your application. Certain guaranteed-issue situations can provide protections when you lose qualifying coverage.
Medicare Advantage has different enrollment periods. Your Initial Enrollment Period, the Annual Enrollment Period in the fall, and certain Special Enrollment Periods may allow you to join or change plans.
How do you decide between Medicare Supplement and Medicare Advantage?
Neither option is automatically right for everyone. Medicare Supplement coverage may appeal to you if broad provider access and more predictable costs matter most. Medicare Advantage may appeal to you if you prefer an all-in-one plan, value added benefits, and are comfortable following a plan’s network and cost-sharing rules.
Before deciding, consider these questions:
- Do you want to keep seeing specific doctors or use particular hospitals?
- Do you travel outside your local area often?
- Would you prefer a lower monthly premium or fewer costs when you receive care?
- Do you need prescription drug coverage?
- Are dental, vision, or hearing benefits important to you?
- Could you manage unexpected copayments if you need frequent care?
