Medigap vs Medicare Advantage in Montrose & Delta counties: a 2026 comparison
Two very different ways to build your Medicare coverage — compared in plain English, with 2026 numbers and their federal sources.
The bottom line
- Original Medicare + Medigap: higher monthly premium, very predictable costs, and any provider nationwide that accepts Medicare — no networks, no referrals.
- Medicare Advantage (Part C): lower (often $0) plan premium and bundled extras, in exchange for a provider network and pay-as-you-go cost sharing, capped at no more than $9,250 in-network in 2026.
- Your one-time 6-month Medigap Open Enrollment Period — starting when you're 65+ and have Part B — is when you can buy any Medigap policy without medical underwriting.
- In 2026, 55% of eligible Medicare beneficiaries nationwide are in Medicare Advantage (KFF) — but the right answer is personal, not popular.
If you live in Montrose, Delta, Olathe, Cedaredge, Paonia, or anywhere along the Uncompahgre and North Fork valleys, here is the short answer: Medigap pairs with Original Medicare to make your costs predictable and lets you see any doctor in the country who accepts Medicare, at a higher monthly premium. Medicare Advantage usually costs less per month and bundles extras, but you agree to a plan network and pay copays as you go, up to an annual limit. Neither is "right" for everyone — the honest answer depends on your doctors, your prescriptions, your travel habits, and your budget. Every number below is for plan year 2026 and linked to its source.
What's the real difference between Medigap and Medicare Advantage?
They solve the same problem — Original Medicare's unlimited cost sharing — in opposite ways.
A Medicare Supplement (Medigap) policy works alongside Original Medicare. Medicare pays its share first; the Medigap policy then pays most of your share of Medicare-approved costs. Because Original Medicare is the network, there is no network: any provider in the U.S. that accepts Medicare, no referrals. Medigap policies are standardized by letter (Plan G and Plan N are the most commonly chosen for people new to Medicare), and they don't include drug coverage — you add a separate Part D plan. See Medicare.gov's Medigap basics.
A Medicare Advantage (Part C) plan replaces how you receive your Medicare benefits: a private plan administers your Part A and B coverage, usually includes Part D drug coverage, and often adds dental, vision, or hearing extras. In exchange, you use the plan's provider network and pay its copays and coinsurance as you go — with an annual in-network out-of-pocket limit that federal rules cap at $9,250 in 2026.
How do they compare side by side?
| What matters | Original Medicare + Medigap | Medicare Advantage (Part C) |
|---|---|---|
| Monthly cost | Part B premium ($202.90 standard in 2026) + Medigap premium + Part D premium | Part B premium ($202.90) + plan premium (often low or $0) |
| Costs when you use care | Highly predictable — after the $283 Part B deductible, Plan G pays most Medicare-approved cost sharing | Copays/coinsurance per visit, capped at the plan's in-network limit (2026 average $5,421; legal maximum $9,250) |
| Doctors & hospitals | Any U.S. provider that accepts Medicare | Plan network (HMO/PPO); out-of-network care costs more or isn't covered |
| Referrals | Not required | Often required in HMO plans |
| Drug coverage | Separate Part D plan (2026 out-of-pocket cap: $2,100) | Usually built in (same $2,100 cap applies to covered drugs) |
| Extras (dental, vision, hearing) | Not included — bought separately if wanted | Frequently included, varies by plan and year |
| Travel & snowbirds | Coverage travels with you nationwide | Emergency care is covered anywhere, but routine care is network-based |
| Changing later | Outside protected windows, switching to Medigap can involve medical underwriting | Can change plans each AEP (Oct 15–Dec 7) or MA-OEP (Jan 1–Mar 31) |

Read those numbers the way an accountant would. The Medicare Advantage out-of-pocket limit is real protection, but it's a ceiling, not a bill — most enrollees spend far less, and a healthy year can cost very little beyond the Part B premium. Medigap flips the math: you pre-pay for certainty through a monthly premium, so a hard year (a joint replacement in Montrose, a cardiac stay in Grand Junction) doesn't change what you owe much at all. Neither approach saves money in every scenario, and no honest advisor will promise that one will.

Two local realities shape this choice on the Western Slope. First, distance: specialty care often means a drive — Montrose Regional Health, Delta Health, or up US-50 to Grand Junction — so whether a plan's network includes the specific hospital and specialists you'd actually use matters more here than in a big metro. Second, health profile: the conditions your neighbors manage are a preview of the care many households will shop for. Here's the CDC's county data (2023, model-based, age-adjusted prevalence among adults):

If you manage blood pressure or arthritis — as roughly a quarter of adults in both counties do — your decision hinges on specifics: is your cardiologist in-network? Is your medication on the formulary, and at what tier? A Medigap policy sidesteps the network question entirely; a Medicare Advantage plan answers it plan by plan, year by year. That's not a reason to avoid either — it's the checklist for choosing.
When can I enroll, and when can I switch?
Timing is where this decision has teeth. Your Medigap Open Enrollment Period is a one-time, 6-month window that starts the first month you're 65 or older and enrolled in Part B. During it, insurers must sell you any Medigap policy they offer, with no medical underwriting. After it closes, in most situations they may consider your health history — charge more, or decline — unless you qualify for a specific guaranteed-issue right.

Medicare Advantage and Part D run on a yearly calendar instead: the Annual Enrollment Period (October 15 – December 7) for joining, dropping, or switching plans effective January 1, and the Medicare Advantage Open Enrollment Period (January 1 – March 31) for one change if you're already in an MA plan. The practical takeaway: you can try Medicare Advantage and change plans annually with little friction — but the door back to Medigap may involve underwriting. The reverse trip is easy. That asymmetry is the single most under-explained fact in this decision.

How do I actually choose?
Skip the ideology and answer four questions:
- Doctors: list every provider you'd be unhappy to lose — including the specialist you see twice a year in Grand Junction or Montrose. Medigap keeps them all (if they take Medicare); for Medicare Advantage, check each one against the plan's directory.
- Drugs: list your prescriptions with dosages. Compare them against real Part D and MA formularies on Medicare Plan Compare — the $2,100 cap protects covered drugs, so coverage status is the whole game.
- Travel: months out of state each year? Grandkids across the country? Nationwide access tilts toward Medigap; staying local most of the year makes a network less costly to accept.
- Budget shape: would you rather pay more monthly for near-zero surprises, or less monthly with a defined worst case (your plan's out-of-pocket limit)? Neither answer is wrong. It's a temperament question as much as a math question.

Medigap vs Medicare Advantage questions, answered
Can I have both a Medigap policy and a Medicare Advantage plan?
No. It's illegal for anyone to sell you a Medigap policy while you're in a Medicare Advantage plan unless you're switching back to Original Medicare. You choose one path: Original Medicare plus Medigap (and usually a separate Part D drug plan), or a Medicare Advantage plan. See Medicare.gov's Medigap basics page.
Which usually costs more each month — Medigap or Medicare Advantage?
Medigap usually has the higher monthly premium, on top of the standard 2026 Part B premium of $202.90 that everyone pays. Many Medicare Advantage plans charge a low or $0 plan premium — but a $0 premium is not $0 cost, because you still pay the Part B premium plus the plan's copays and coinsurance as you use care, up to its out-of-pocket limit.
What protects me from big bills under each option in 2026?
With Medicare Advantage, plans must cap your in-network out-of-pocket costs at no more than $9,250 in 2026 (many set lower limits; the enrollment-weighted average is $5,421, per KFF). With Original Medicare plus Medigap, the supplement pays most Medicare-approved cost sharing after you meet the $283 Part B deductible, which is what makes costs predictable.
Can I switch from Medicare Advantage to Medigap later?
You can leave a Medicare Advantage plan during certain enrollment periods, but outside your one-time 6-month Medigap Open Enrollment Period, insurers in most situations can use medical underwriting — meaning they may charge more or decline coverage based on health history, unless you qualify for a guaranteed-issue right. That's why this decision deserves care the first time.
Does Medigap include prescription drug coverage?
No. Medigap policies sold today don't cover prescription drugs. If you choose Original Medicare plus Medigap, you'll generally want a separate Part D drug plan. In 2026, your out-of-pocket costs for covered Part D drugs are capped at $2,100 for the calendar year.
Is Bemis Insurance part of Medicare or the government?
No. Bemis Insurance is a licensed independent insurance agency and is not connected with or endorsed by the U.S. government or the federal Medicare program. For every option available to you, contact Medicare.gov, 1-800-MEDICARE, or Colorado's State Health Insurance Assistance Program (SHIP).
