Medicare Advantage vs. Original Medicare: Which is best for you? offers tips and infographic for comparing coverage during Medicare open enrollment, which ends Dec. 7

November 15, 2023

Minneapolis – With Medicare open enrollment underway, it’s helpful for consumers to understand the difference between Original Medicare and Medicare Advantage. Today, offered tips and a new infographic to help people compare coverage and possibly save money.

Medicare open enrollment – also known as the annual election period – ends Dec. 7. During the open enrollment period, millions of Medicare enrollees can:

  • Switch from Original Medicare to Medicare Advantage, or vice versa.
  • Switch from one Medicare Advantage plan to another.
  • Make changes to their Medicare Part D prescription drug plans (Part D). This includes dropping or enrolling in stand-alone Medicare Part D prescription drug plans.

“As beneficiaries compare different Medicare plans, they may be confused by the differences or overwhelmed by all the options,” said Louise Norris, a health policy analyst for “But that shouldn’t stop them from doing the research. Comparing plans during Medicare open enrollment really can help consumers save money.”

“It’s hard to overemphasize how many Americans are potentially impacted by open enrollment season,” Norris added.

“Of approximately 60 million eligible Medicare beneficiaries, 51% are enrolled in Medicare Advantage plans in 2023 – a significant jump from the 19% enrolled in 2007, according to KFF,” Norris said.

Here are a few things to consider when deciding between Original Medicare versus Medicare Advantage, or pairing Original Medicare with a Medigap or Part D plan.

Premiums are part of the equation

In most areas, there are “zero-premium” Medicare Advantage plans available. However, enrollees who buy these plans still must pay the Medicare Part B premium, which is $174.70 a month for most enrollees in 2024.

People who opt for Original Medicare with supplemental coverage – assuming they don’t have supplemental coverage from Medicaid or an employer-sponsored plan — will pay a Medigap and/or Part D premium in addition to the Part B premium.

The average premium for a stand-alone Part D plan in 2024 is projected by KFF to be $48/month based on current enrollment, but expected to be less than that once enrollees finalize their plan selections for 2024. And as is always the case, premiums vary widely from one plan to another.

“Zero-premium Medicare Advantage plans can be attractive for some people,” Norris said. “But while Original Medicare paired with Medigap coverage may come with a higher monthly premium, the supplemental coverage could substantially lower out-of-pocket costs, and the Original Medicare and Medigap combination will allow access to a larger number of medical providers.”

Out-of-pocket costs vary significantly

With most Medicare Advantage plans, beneficiaries will pay a deductible, coinsurance and/or copays, and the out-of-pocket maximum can be as high as $8,850 in 2024 for services covered under Medicare Parts A and B. Also, people with Medicare Advantage plans will have additional out-of-pocket costs for prescription drugs. Most Medicare Advantage plans do cover prescription drugs, but the out-of-pocket costs are not applied to the regular medical out-of-pocket limit.

If people pair Original Medicare with Medigap, there are plans available that pay nearly first-dollar coverage for all Original Medicare-covered services, leaving enrollees with potentially very little in out-of-pocket costs other than the cost of medications under Medicare Part D. The most comprehensive Medigap plans tend to be among the more expensive options. Less-expensive options leave enrollees with varying amounts of out-of-pocket costs for services that are covered by Original Medicare.

Medicare Advantage plans may have extra benefits, limitations

When exploring plans, also consider the provider network, extra benefits and how care will be covered if you travel:

  • Provider network: Original Medicare has a broader provider network with nationwide coverage. Medicare Advantage plans each have their own network, which are generally more limited in terms of providers and geographic coverage area.
  • Travel: If you plan to travel, consider that Original Medicare doesn’t cover medical expenses incurred in foreign countries, except for a few rare circumstances. Some Medigap plans provide some coverage of medical expenses for enrollees traveling internationally. With Medicare Advantage, health coverage during domestic and foreign travel varies from plan to plan. Medicare Advantage plans offer nationwide emergency room
  • Prescription drug costs: Most Medicare Advantage plans include Medicare Part D drug coverage, but if you’re considering a Medicare Advantage plan, it’s a good idea to confirm and make sure. Each Medicare Advantage plan will also have its own preferred drug list and benefit design, which determines how much you pay for your prescriptions. If you stick with Original Medicare, you will need to purchase a stand-alone Part D plan if you want prescription drug coverage. These plans are offered by private carriers, and the cost and benefits will vary from one plan to another.
  • Extra benefits: Medicare Advantage plans often offer extra benefits – which may include, for example dental, vision, hearing aids, and gym memberships – that are not offered by Original Medicare.

“Plan details can change from year to year,” Norris said. “Even if you’re satisfied with your existing coverage, it’s worth comparing plans since plan details can change from year to year.”
