THE HONEST COMPARISON
Medicare Advantage vs. Medicare Supplement: Which Path Is Right for You?
You’ve done the reading. Now you need to actually choose — and that choice matters more than most financial decisions you’ll make in retirement.
Neither path is universally better. The right answer depends on five specific things: your doctors, your prescriptions, your budget, your health, and how you use care. This page walks you through a real decision framework — plus the one thing almost nobody warns you about before you choose.
We’re Boo Insurance Services, an independent Medicare brokerage in Utah. We’re not tied to any insurance company — which means we have no reason to push you toward one path over the other. Our help comparing both options is completely free.

ONE SENTENCE EACH
Two Completely Different Structures
Medicare Advantage (Part C)
Replaces how you receive Original Medicare. A private plan delivers your hospital and medical coverage — through its own network, its own rules, usually with drug coverage and extras bundled in.
Medicare Supplement (Medigap)
Keeps Original Medicare as your primary coverage and pays the gaps it leaves behind — the deductibles and that uncapped 20% coinsurance — so you pay little or nothing at the point of care.
You cannot have both at the same time. They are two completely different structures — not variations of the same thing. Choosing one means not choosing the other.
SIDE BY SIDE
Where the Real Differences Show Up
| Medicare Advantage | Medigap + Original Medicare | |
|---|---|---|
| Monthly premium | Often $0 + Part B ($202.90) | ~$100–150+ + Part B |
| Provider access | Network only (HMO or PPO) | Any Medicare provider nationwide |
| Drug coverage | Usually bundled in | Add separate Part D plan |
| Dental / vision / hearing | Often included | Not included |
| Prior authorization | Common | Rare |
| Annual OOP cap | $9,250 max in-network | $283/yr with Plan G |
| Travel / out-of-area | Limited to service area | Nationwide, any Medicare provider |
| Best year cost | Low — $0 premium + light copays | Medigap premium regardless of use |
| Hard year cost | Up to $9,250 in-network | As little as $283 (Plan G) |
Table reflects general plan structures. Actual costs vary by plan, carrier, and county. Verify your specific plan details before enrolling.
THE COMPARISON MOST PEOPLE SKIP
Healthy Year vs. Hard Year — The Cost Reality
Which path is actually cheaper depends entirely on what kind of year you’re having.
Healthy year: Advantage wins
$0 premium + light copays vs paying a Medigap premium every month for coverage you barely touched. Advantage can save several hundred dollars in a low-use year.
Hard year: Medigap wins
Hospital + surgery + specialists stack toward Advantage's $9,250 cap. Medigap Plan G: $283 deductible, then $0 regardless of how much care you need.
| Healthy Year (light use) | Hard Year (hospital + surgery) | |
|---|---|---|
| Medicare Advantage ($0 plan) | ~$240–480 in copays + Part B = ~$2,675–2,916/yr total | Copays + coinsurance can reach $4,000–9,250 depending on plan |
| Medigap Plan G (~$130/mo) | $283 deductible + $1,560 Medigap premiums + Part B = ~$4,278/yr | $283 Part B deductible, then $0 regardless of care needed |
| Difference | Advantage saves ~$1,000–1,600 | Medigap saves ~$3,700–8,967 |
Illustrative scenarios using current-year figures. Actual Advantage costs vary by plan design, county, and services used. Always review the plan's Summary of Benefits before enrolling.
The honest framing: you’re not choosing which plan is cheaper. You’re choosing which financial risk you’re more comfortable carrying — the premium risk (you pay it whether healthy or sick) or the utilization risk (you pay more when something serious happens).
THE FRAMEWORK
The 5 Questions That Decide This
- Are your current doctors in a Medicare Advantage network? Medigap works with any Medicare-accepting provider. Advantage limits you to in-network — always verify before enrolling. This is the most common regret.
- Are your prescriptions covered — at what cost? With Advantage, check the plan formulary. With Medigap, check your standalone Part D plan. Non-negotiable for either path.
- How much care do you typically use? Healthy + light use → Advantage likely saves money most years. Chronic conditions + multiple specialists → Medigap's predictable cost floor becomes the better hedge.
- Do you travel or value nationwide provider access? Advantage is tied to a local service area. Medigap is nationwide — same coverage at home, in St. George, or visiting family out of state.
- How do you feel about referrals and prior authorization? HMO Advantage plans can require both. Medigap almost never does. If approval delays would frustrate you: lean Medigap.
THE THING NOBODY WARNS YOU ABOUT
The Switching Trap: Easy In, Hard Back.
Medigap → Advantage: Easy
Any Annual Enrollment Period — no health questions. Advantage plans cannot underwrite you. The door is always open.
Advantage → Medigap: Hard
Usually requires medical underwriting. The carrier reviews your health and can charge more or decline you outright. The people most motivated to switch are most likely to be refused.
⏳ The 12-month trial right: if you joined Medicare Advantage when first eligible at 65, federal law gives you 12 months to switch back to Medigap with no underwriting. After month 12, that door closes.
Your choice at 65 isn’t just which plan is best this year — it’s which path you want to be on. One direction of travel is significantly easier than the other. For full detail on Medigap underwriting and Utah’s birthday rule, read our Medicare Supplement guide.
MAKING IT ACTIONABLE
Choose Based on What Matters Most to You
Choose Medicare Advantage if...
- Your doctors and hospital are all in the plan's network
- You want $0 premiums and are comfortable with copays when you use care
- You value dental, vision, hearing, and fitness benefits bundled in
- You're generally healthy — light on medical visits
- You stay mostly in your local service area
- You're comfortable with networks and occasional prior authorization
Choose Medigap if...
- You see multiple specialists or have ongoing health conditions
- Provider freedom matters — any doctor, anywhere, no network
- You want maximum cost predictability: pay premium, know your exposure
- You travel frequently or split time between Utah and another state
- Prior authorization would frustrate or delay the care you need
- You're a military retiree with TRICARE For Life
Neither list is absolute. These are starting points — your specific doctors, prescriptions, and plan options in your area are what actually decide.
BEFORE YOU FINALIZE
A Third Strategy Worth Knowing About
Before you make your final decision, there’s a coverage approach many Utah residents have never heard of — and it changes the math on Medicare Advantage in ways the TV ads never mention.
Some people pair a low-premium Medicare Advantage plan with a hospital indemnity policy. A hospital indemnity plan pays a fixed cash benefit during the exact events that drive most Medicare Advantage out-of-pocket spending — a hospital stay, skilled nursing care, ambulance transport. That combination can substantially offset the big-ticket costs of a Medicare Advantage plan for a fraction of what a Medigap premium would cost each month.
It doesn’t remove Advantage’s network rules or prior authorization requirements. But for the right person, it can close much of the cost exposure gap between the two paths — at a meaningfully lower total monthly cost than Medigap.
Hospital indemnity is not Medicare coverage. Benefits are fixed cash amounts per qualifying event, not reimbursement for actual costs. A conversation with a licensed broker is the best way to compare total costs across all three approaches.
STAR RATINGS
What About Medicare Advantage Star Ratings?
Medicare rates every Advantage plan 1–5 stars based on quality of care and service. In Utah, SelectHealth has historically received strong ratings (including 5-star years). Newer national carriers entering the market may carry lower ratings initially. Higher-rated plans sometimes carry more restrictions; lower-rated plans may have looser networks.
Star ratings measure quality and service — not whether the plan’s network includes your specific doctors. That remains the first check. CMS publishes ratings at medicare.gov/plan-compare — run your actual doctors and prescriptions through the tool before enrolling.
COMMON QUESTIONS
Frequently Asked Questions
No. They’re mutually exclusive — you choose one path or the other. Medigap supplements Original Medicare; Medicare Advantage replaces it. Having both simultaneously is not allowed.
Neither is universally better. Advantage typically costs less in healthy years; Medigap typically costs less in high-care years. The right choice depends on your doctors, prescriptions, travel habits, health, and risk tolerance. Use the five questions in this guide as your framework.
You can, but it usually requires passing medical underwriting — the carrier reviews your health and can decline coverage. The exception: if you’re in your first 12 months on Advantage (having just turned 65), you have a guaranteed right to switch to Medigap without underwriting. After that, standard rules apply.
If you have TRICARE For Life (TFL) and both Medicare Part A and Part B, TFL acts as your Medigap — covering your cost-sharing and prescriptions. TFL coordinates seamlessly with Original Medicare but does NOT coordinate with Medicare Advantage the same way. Staying on Original Medicare is almost always the right call. See the full TRICARE section in our Turning 65 guide.
It can be — the key is whether your doctors and specialists are in-network and whether the plan’s formulary covers your medications at manageable cost. For high ongoing medical usage, Medigap’s predictable cost floor often makes more financial sense, but it depends on your specific plan options and actual utilization.
Emergencies are always covered anywhere. Routine care outside your plan’s service area is generally limited. If you split time between Utah and another state, or travel frequently, Medigap’s nationwide coverage is a significant practical advantage.
Insurance companies receive a monthly payment from Medicare for each Advantage enrollee — which funds both the benefits and the marketing. Heavy advertising doesn’t mean a plan is better. An independent broker has no financial incentive tied to which path you choose and can compare options across all carriers on both sides.
