Medicare Advantage vs. Medicare Supplement vs. ACA Marketplace
The single most common question we get, answered honestly and side by side — no sales pitch, just how each option actually works.
Quick Comparison
How they stack up
| Medicare Advantage | Medicare Supplement (Medigap) | ACA Marketplace | |
|---|---|---|---|
| Who it's for | Medicare-eligible (65+ or disability) | Medicare-eligible (65+ or disability) | Under 65, no employer coverage |
| Typical monthly premium | Often $0–$50 (still pay Part B) | $110–$200+ (varies by plan letter & county) | Varies widely — often reduced sharply by subsidies |
| Provider network | HMO or PPO network required | Any provider nationwide accepting Medicare | Marketplace plan's network (varies by insurer) |
| Referrals needed | Often, for HMO plans | Never | Depends on plan type (HMO/PPO) |
| Extra benefits | Often dental, vision, hearing, gym | None built in — add separately | Varies by metal tier and insurer |
| Annual out-of-pocket max | Yes — every plan sets an in-network limit (amount varies by plan) | No cap needed — Medigap covers nearly all cost-sharing | Yes — varies by plan and metal tier |
| Nationwide coverage | No — network-restricted | Yes — any Medicare provider, any state | No — state/insurer-specific network |
| Cost predictability | Variable — depends on how much care you use | Very high — same premium regardless of usage | Variable — depends on plan and subsidy |

A Closer Look
What each option is actually best at
Medicare Advantage
Best if you want bundled extras and a lower premium
Medicare Supplement (Medigap)
Best if predictability and provider freedom matter most
ACA Marketplace
Best if you're under 65 without employer coverage
Quick Guidance
A rough starting point
If you're under 65 and don't have employer coverage — the ACA Marketplace is your option; Medicare isn't available to you yet.
If you're 65+, travel often, or want to keep seeing specific specialists without network restrictions — Medigap is usually the stronger fit.
If you're 65+, healthy, budget-conscious, and comfortable with a managed network — Medicare Advantage's bundled benefits often deliver strong value.
If you live in rural Wyoming or a county with thin Advantage networks — Medigap's nationwide access tends to matter more than it does in denser Utah metro areas.
Common Questions
Questions people ask before deciding
Can I have Medicare Advantage and Medigap at the same time?
No. You choose one path or the other. Medicare Advantage replaces Original Medicare for most of your care, while Medigap works alongside it. You can't legally be sold a Medigap policy while enrolled in a Medicare Advantage plan.
Is ACA Marketplace insurance the same as Medicare?
No. Medicare is a federal program primarily for people 65+ or with qualifying disabilities. The ACA Marketplace serves people under 65 without employer coverage. Once you're Medicare-eligible, Marketplace subsidies generally end.
Which is cheaper: Medicare Advantage or Medigap?
It depends on how much care you use. Advantage often has a lower premium but variable cost-sharing up to an annual cap. Medigap has a higher premium but very predictable, often near-zero, costs after the Part B deductible.
Can I switch from Medicare Advantage back to Medigap later?
You can return to Original Medicare, but re-enrolling in Medigap outside your initial guaranteed-issue window may require medical underwriting in most states, including Wyoming and Utah — an insurer can deny coverage or charge more.
Do I need help deciding between these options?
Most people do — the right answer depends on your specific doctors, prescriptions, budget, and county. An independent advisor can walk through your actual numbers at no cost, since advisors are paid by carriers, not by you.
