Original Medicare vs. Medicare Advantage
Your path to Medicare begins with one choice: Original Medicare or Medicare Advantage.
Whether you should choose Original Medicare or Medicare Advantage depends on what you need from your health insurance. We’ll discuss each option in depth, weigh the pros and cons, and help you make an informed decision about your future in Medicare.
What’s the difference between Original Medicare and Medicare Advantage?
The biggest difference between Medicare and Medicare Advantage is the provider. The government provides original Medicare; private insurance companies provide Medicare Advantage. Both providers have different methods of administering health care.
What is Original Medicare and how does it work?
Original Medicare (sometimes called Traditional Medicare) is the government-provided option for health-care coverage for anyone 65 and older or people with qualifying disabilities. Original Medicare consists of two components: Part A and Part B.
Medicare Part A is colloquially called hospital insurance, although it covers more than just that. Part A covers hospitals and skilled nursing facilities as long as you’re admitted as an inpatient. Part A also covers hospice care. Most people get Part A for free if they (or their spouse) worked long enough and paid Medicare taxes—about 10 years total.
Medicare Part B is called medical insurance and covers just about everything else (with the notable exception of prescription drugs). Medicare Part B covers doctors, specialists, outpatient procedures, lab tests, durable medical equipment, and so on. Part B requires a monthly premium, which most people pay through a deduction on their Social Security payment.
Most people sign up for both Medicare Part A and Part B, although you don’t technically have to. You’ll never be forced to enroll in any part of Medicare you don’t want to. Just understand that if you decide later you want Part B, you’ll face some hefty late enrollment penalties.
Original Medicare: the à-la-carte approach
If you choose Original Medicare instead of Medicare Advantage, you can tailor your coverage in an à-la-carte fashion, adding up to two more components (each of which requires an additional monthly premium):
- Part D covers prescription drugs. Private insurance companies sell standalone Part D plans that you may add to your coverage.
- Medigap (or Medicare Supplement) plans lower your copayments, deductibles, and other Medicare costs. Private insurance companies sell Medigap plans as well. There are several plans to choose from with varying coverage amounts, and two Medigap plans—Plans K and L—provide the only means of getting an out-of-pocket limit within Original Medicare.
What is Medicare Advantage and how does it work?
Medicare Advantage (often called Medicare Part C) is the privatized version of Medicare, consisting of individual health plans managed and sold by private insurance companies. Medicare Advantage resembles employer-sponsored health plans with components like networks, preferred providers, and out-of-pocket limits.
Medicare Advantage plans may have different management methods, but most often you'll see two kinds:
- A Health Maintenance Organization (HMO), which covers care only within a local network—unless it’s an emergency.
- A Preferred Provider Organization (PPO), which covers doctors and services both in and out of a network—but anything outside the network may cost more.
Medicare Advantage: The bundled approach
Medicare Advantage plans bundle Medicare coverage into one comprehensive package, including at least Part A and Part B coverage. Most plans also include Part D prescription drug coverage as well. There are also additional benefits that you cannot get through Original Medicare.
Here are a few of the extra benefits you may see in a Medicare Advantage plan:
$0 premium Medicare Advantage plans: essential details
Companies may offer $0 Medicare Advantage plans—which can be fantastic—but don’t think those plans are free. If you sign up for Medicare Advantage, you’ll still pay a premium to Medicare for Part B (and Part A if you didn’t work long enough).
Why do you have to pay for a service you’re not using, you might ask? Because when you sign up for Medicare Advantage, the federal government reimburses your plan sponsor for taking you on as a liability. So you pay the Part B premium to Medicare, and the federal government sends that money (and then some) to your Medicare Advantage plan sponsor.
In essence, a $0 premium Medicare Advantage plan means you won’t be paying more than you would for Original Medicare. But these plans can still be cheaper overall—especially if they include Part D prescription drug coverage. A standalone Part D plan with Original Medicare always requires an additional premium. Plus, the additional benefits (referenced above) add significant value to a plan that doesn’t cost a penny more than Traditional Medicare.

Which is better: Original Medicare or Medicare Advantage?
After reading the comparisons, the pros, and the cons, you probably already have an idea which option may be best for you. But in case you need an extra nudge, here are some tips that can help you choose based on your lifestyle and budget.
Original Medicare is best for…
- Snowbirds, sunbirds, RVers, or people who frequently travel.
- People who want more customizable coverage.
- People who expect higher health care (but only if the base coverage is supplemented with a Medigap plan)
- Those who don’t mind paying extra for more coverage (Part D, Medigap, Dental insurance, etc.)
Original Medicare is usually the best choice for travelers. As long as you also have a Medigap policy, Original Medicare covers quite a bit of your costs and can turn higher medical bills into predictable monthly payments. And since Original Medicare allows you to add whatever Part D and Medigap plan you like, you can customize your coverage more than you can with Medicare Advantage.
However, all that customization doesn’t come cheap. Each component you add requires a monthly premium, which may be out of the budget for people on fixed incomes.
Medicare Advantage is best for…
- Those who want supplemental benefits
- People who prefer coverage similar to employer-sponsored plans
- People who like bundled coverage
- Anyone who doesn’t anticipate having high health needs
- Those on a budget
With Medicare Advantage, you can generally get more for less: more perks, coverage for services not included in Original Medicare (like dental, vision, hearing), out-of-pocket limit, and so on. It's an excellent option for people on a budget since there are so many $0 premium plans out there, which often include Part D prescription drug coverage—coverage you’d need to pay an additional premium for if you were in Original Medicare. And the number of benefits packed into plans nowadays is a huge perk.
However, Medicare Advantage isn’t for everyone. Since plans can change each year, enrollees need to stay on top of the changes so they can determine whether a switch might be necessary. Similarly, if you anticipate frequently using your health care coverage, you may end up spending more than you would on Original Medicare.
Whether you choose Medicare Advantage or Original Medicare, you’ll need to sign up for Original Medicare first, before you can change your coverage. If you haven’t done that yet, read how to enroll in Original Medicare.
