If you’re new to Medicare in 2026, one of the biggest decisions you’ll make is how to fill the gaps that Original Medicare (Parts A and B) leaves behind. Original Medicare alone doesn’t cover everything, so most people choose one of two paths: a Medigap (Medicare Supplement) policy or a Medicare Advantage (Part C) plan. They work very differently, and the right choice depends on your health, budget, and how you like to get care. Here’s a plain-English comparison to help you decide.
The two paths at a glance
Think of it as a fork in the road. With Medigap, you keep Original Medicare and add a supplement that pays most of your out-of-pocket costs; you’ll also add a separate Part D drug plan. With Medicare Advantage, a private insurer bundles your Parts A, B, and usually D into one plan, often with extra perks — but you agree to use the plan’s network and rules. You can’t use both at the same time, so it’s one or the other.
Medicare Advantage (Part C): all-in-one convenience
Medicare Advantage plans are offered by private insurers and combine your hospital, medical, and drug coverage into a single plan. Many include extras Original Medicare doesn’t, like dental, vision, hearing, and gym memberships.
The upsides: premiums are often low (sometimes $0 beyond your Part B premium), everything is bundled together, and there’s a yearly cap on what you’ll pay out of pocket. In 2026, that in-network out-of-pocket maximum can be no higher than $9,250, and many plans set it lower.
The trade-offs: you’re limited to the plan’s provider network (HMO or PPO), you often need referrals and prior authorizations, and your copays add up as you use care. If you travel a lot or want to see specialists outside your area, the network can feel restrictive.
Medigap (Medicare Supplement): freedom and predictability
A Medigap policy works alongside Original Medicare. Instead of a network, you can see any doctor or hospital in the country that accepts Medicare — no referrals needed. The supplement then pays most or all of the deductibles and coinsurance Original Medicare leaves for you.
The upsides: maximum freedom to choose your doctors, very predictable costs (you pay a monthly premium and little else at the point of care), and great coverage for people who travel or want to keep specialists at any Medicare-accepting facility.
The trade-offs: monthly premiums are higher than most Advantage plans, and Medigap doesn’t include drug coverage or extras like dental and vision — you’ll add a separate Part D plan and pay for those extras on your own.
Side-by-side comparison
- Monthly premium: Medicare Advantage is usually lower; Medigap is usually higher.
- Costs when you get care: Advantage has copays that add up; Medigap is very predictable with little to pay at the doctor.
- Choice of doctors: Advantage limits you to a network; Medigap lets you use any provider that accepts Medicare nationwide.
- Referrals & prior authorization: common with Advantage; generally not required with Medigap.
- Drug coverage: usually built into Advantage; a separate Part D plan with Medigap.
- Extras (dental, vision, hearing): often included with Advantage; not included with Medigap.
- Yearly out-of-pocket cap: Advantage has one (no more than $9,250 in-network in 2026); Medigap has no cap but keeps your costs low and steady.
Which one is right for you?
There’s no single best answer — it depends on what matters most to you. Medicare Advantage tends to fit people who want a low monthly premium, like having everything bundled with extras, are comfortable using a network, and don’t mind copays as they go. Medigap tends to fit people who want the freedom to see any doctor, value predictable costs, travel often, or have ongoing health conditions where steady, comprehensive coverage brings peace of mind.
Timing matters more than most people realize
Here’s something important for anyone new to Medicare: when you first enroll at 65, you get a one-time Medigap Open Enrollment window (6 months, starting when your Part B begins) where you can buy any Medigap policy with guaranteed acceptance — no health questions, no denials. After that window closes, insurers can review your health and even turn you down. Medicare Advantage doesn’t have that health-screening barrier, but switching later isn’t always as simple as it sounds. Getting this decision right the first time can save you money and stress for years.
