Medicare Advantage vs. Medigap: Which One Actually Fits You?

Once you're eligible for Medicare, you face a fork in the road: Medicare Advantage (Part C) or Original Medicare plus a Medigap (Supplement) policy. Both are good options. Neither is universally 'better.' The right call depends on your doctors, your budget, and how much you travel.
The short version
Medicare Advantage bundles everything (hospital, medical, usually drugs, often dental/vision/hearing) into one plan from a private insurer. Premiums are low or $0, but you're tied to a network and need referrals on some plans.
Medigap works with Original Medicare and pays the deductibles and coinsurance Medicare doesn't. Higher monthly premium, but you can see any doctor that accepts Medicare and there are no networks.
Choose Medicare Advantage if…
- You're comfortable with HMO/PPO networks
- You want extras like dental, vision, OTC, gym
- You prefer a low or $0 monthly premium
- You don't travel much outside your service area
Choose Medigap if…
- You travel often or split time between states
- You see specialists frequently or have complex conditions
- You want predictable out-of-pocket costs
- You don't mind paying a higher monthly premium for flexibility
The catch most people miss
In most states, switching from Advantage back to Medigap later in life is allowed — but you can be medically underwritten and even denied. If you're healthy at 65, Medigap is usually easier to get into now than five years later.
What to do next
Don't guess. Have a licensed agent run a side-by-side comparison using your actual doctors and prescriptions. It's the cheapest, fastest way to know — and it's free.
