Original Medicare vs Medicare Advantage
Freedom and predictability versus a cap and extras. And a door that can be hard to go back through.
Every person with Medicare chooses, at least by default, between two ways of getting coverage. Original Medicare is run by the federal government. Medicare Advantage plans are private plans approved by Medicare.
Both cover the same basic services. What differs is how you get care, how costs are structured, and how easy it is to change your mind later.
Side by side
| Original Medicare | Medicare Advantage | |
|---|---|---|
| Doctors and hospitals | Any provider in the US that accepts Medicare, no referrals needed | Usually a network; HMOs generally need referrals and in-network care |
| Out-of-pocket limit | None on its own | Required, up to $9,250 in-network in 2026 |
| Filling the gaps | Medigap, employer retiree coverage or Medicaid | Built into the plan's cost sharing; can't add Medigap |
| Drug coverage | Separate Part D plan | Usually included |
| Premiums | Part B, plus Part D and any Medigap premium | Part B, plus any premium the plan charges |
| Prior authorization | Rare (limited models in some states) | Common for many services |
| Extra benefits | None beyond Medicare's coverage | Some plans offer limited dental, vision, hearing or fitness |
| Travel within the US | Coverage works nationwide | Often limited to emergencies and urgent care outside the service area |
Who tends to prefer Original Medicare
People who want to choose any specialist or hospital without referrals, who spend time in more than one state, or who have or expect serious conditions often value Original Medicare's flexibility. Pairing it with a Medigap policy makes costs predictable: you pay higher premiums, but little when you use care.
Who tends to prefer Medicare Advantage
People comfortable using a network, who want a yearly out-of-pocket limit without paying a Medigap premium, or who value combined drug coverage and extra benefits in one plan often choose Medicare Advantage. Costs are lower when you're healthy and higher when you use a lot of care, up to the plan's limit.
The switching-back trap
You can leave Medicare Advantage for Original Medicare every year during Open Enrollment, or from January 1 to March 31. But buying a Medigap policy later is a different matter. Outside your one-time Medigap Open Enrollment Period and a few guaranteed issue situations, insurers in most states can ask health questions and turn you down.
If you try Medicare Advantage when you first get Medicare at 65, a federal trial right lets you return within 12 months and buy any Medigap policy. A few states go further and let you switch Medigap plans every year. Check your state's rules before you decide.
Questions to answer before you choose
- Are my doctors, hospitals and pharmacies in the plan's network, and do I care if that changes?
- How much would I pay in a bad year, not just a good one?
- Do I travel or live part of the year in another state?
- Could I pass medical underwriting for Medigap later if I change my mind?
- Are my drugs on the plan's formulary, and with what restrictions?
Common questions
Premiums are often lower, but total cost depends on how much care you use. In a year with a lot of care, you could pay up to the plan's out-of-pocket limit. With Original Medicare plus Medigap, you pay higher premiums and usually little else.
Yes, during Medicare Open Enrollment (October 15 to December 7) or the Medicare Advantage Open Enrollment Period (January 1 to March 31). Getting a Medigap policy afterward may require passing medical underwriting, depending on your situation and state.
They must cover all medically necessary services Original Medicare covers, except hospice, which Original Medicare still pays for. They can apply different rules, such as prior authorization and networks.
