Medigap vs. Medicare Advantage: Which May Fit You Best?
What Colorado Medicare beneficiaries need to know about provider choice, costs,
drug coverage, and how these two Medicare paths really work
drug coverage, and how these two Medicare paths really work
One of the biggest Medicare decisions is whether to choose Original Medicare with a Medigap plan or a Medicare Advantage plan.
Both options can provide strong coverage, but they do not work the same way. The right fit depends on what matters most to you, including doctor choice, monthly premium, out-of-pocket exposure, travel habits, and how comfortable you are working within a plan network.
At National Benefits Consultants, we help Colorado Medicare beneficiaries understand the real differences between Medigap and Medicare Advantage so they can make more confident decisions.

The short version
A Medigap plan works with Original Medicare and helps pay certain out-of-pocket costs like deductibles, copayments, and coinsurance. Original Medicare lets you use any doctor or hospital in the U.S. that takes Medicare. Medigap is separate insurance sold by private companies.
A Medicare Advantage plan is another way to get your Medicare benefits through a private company approved by Medicare. These plans cover everything Original Medicare covers, but may have different costs, rules, networks, referrals, and prior-authorization requirements. Many also include prescription drug coverage.

How Medigap works
Medigap is extra insurance you buy to go with Original Medicare Part A and Part B. Its purpose is to help pay your share of out-of-pocket costs in Original Medicare. You generally must have Part A and Part B to buy a Medigap policy, and as long as you keep paying the premium, the policy is generally guaranteed renewable.
Medigap generally does not include:
Medigap generally does not include:
- prescription drug coverage
- routine dental
- routine vision
- hearing aids
- long-term care
How Medicare Advantage works
Medicare Advantage is a private-plan alternative to Original Medicare. These plans must cover all medically necessary services that Original Medicare covers, but they can set their own cost-sharing and use plan rules like:
- provider networks
- referrals
- prior authorization
- different out-of-pocket costs
- prescription drug coverage
- dental, vision, or hearing benefits
- other extra benefits not covered by Original Medicare
Key differences between Medigap and Medicare Advantage
1. Provider choice
With Original Medicare plus Medigap, you can generally see any doctor or hospital in the U.S. that accepts Medicare.
With Medicare Advantage, plans may require you to use doctors, hospitals, and suppliers in the plan’s network for non-emergency care, depending on the plan type.
2. Monthly premiums
With Medigap, you usually pay:
3. Out-of-pocket structure
With Medigap, monthly premiums are often higher, but out-of-pocket medical costs can be more predictable because the plan helps cover Medicare cost-sharing.
With Medicare Advantage, monthly premiums may be lower, but you may pay more as you use services through copays, coinsurance, and plan cost-sharing. Medicare Advantage plans do have an annual out-of-pocket maximum for covered Part A and Part B services, while Original Medicare by itself does not.
4. Drug coverage Medigap
Does not generally include prescription drug coverage, so you usually need separate Part D.
Medicare Advantage plans often include prescription drug coverage, though not every plan does.
5. Rules and flexibility Medigap
With Original Medicare is usually simpler from a provider-access standpoint because you are using Original Medicare’s national framework.
Medicare Advantage plans can change costs, provider networks, and plan rules from year to year, so annual review matters.

2. Monthly premiums
With Medigap, you usually pay:
- your Part B premium
- a separate Medigap premium
- usually a separate Part D premium if you want drug coverage
3. Out-of-pocket structure
With Medigap, monthly premiums are often higher, but out-of-pocket medical costs can be more predictable because the plan helps cover Medicare cost-sharing.

When Medigap may appeal more
Medigap may be a better fit for people who:
- want broader provider choice
- travel often in the U.S.
- prefer more predictable medical cost-sharing
- are comfortable paying higher monthly premiums for that tradeoff
- want the flexibility of Original Medicare access nationwide
When Medicare Advantage may appeal more
Medicare Advantage may appeal more to people who:
- want a lower monthly premium structure
- like having medical and drug coverage bundled in one plan
- are comfortable with plan networks and utilization rules
- want extra benefits like dental, vision, or hearing that Original Medicare does not cover
Timing matters with Medigap
Your federal Medigap Open Enrollment Period lasts 6 months and starts the first month you have Part B and are 65 or older. During that period, you can buy any Medigap policy sold in your state, even if you have health problems. After that window, you may not have the same protections unless you qualify for a guaranteed-issue right or state-specific rule.
That means a Medicare beneficiary who skips Medigap at the start may have fewer options later.

Questions to ask before choosing
1. Do I want the broadest doctor access possible?
If yes, Original Medicare plus Medigap may be more attractive.
2. Am I comfortable using a network?
If not, Medicare Advantage may feel restrictive depending on the plan.
3. Do I want one bundled plan with drug coverage?
That may push you toward Medicare Advantage, since many plans include drug coverage.
4. Am I still in my Medigap Open Enrollment window?
If yes, that is an important opportunity because you may be able to buy Medigap without medical underwriting.
5. Am I focused more on lower monthly premium or lower medical cost uncertainty?
This is often the real tradeoff between the two paths. This is an inference based on how Medicare and Medigap structure premiums and cost-sharing.
