The honest answer is that it depends on the individual plan rather than the carrier, and it can change during the year. Here is what is actually knowable, and how to settle it for your own plan in about ten minutes.
Free hospital check
Is Gundersen in the plan you’re looking at? I’ll check for you.
Enter your ZIP code. I’ll check Gundersen, and any doctors you name, against every 2026 marketplace plan filed in your county, then send you the plans that include them and the date I checked. It costs nothing, and I only call if you ask me to.
- Your ZIP code
- Who to check — Gundersen is filled in
- My answer, usually the same day
Open Enrollment for 2027 opens November 1. Molina is leaving Wisconsin’s marketplace for 2027. If your plan is from Molina, it ends December 31, and the plan that replaces it may not include Gundersen. I’ll check the 2027 plans for you before you choose.

“I run my own business and my time is valuable. Daniel handled everything — compared the private options, explained what I was actually getting, and had me covered fast. Way better experience than trying to navigate it myself.”
Insurance at Gundersen: the short answer
These 5 insurers sell 2026 marketplace plans in the 4 counties it serves: Anthem Blue Cross and Blue Shield, Medica, Quartz, Security Health Plan and Dean Health Plan.
That is not a list of plans Gundersen accepts. Hospitals contract with individual plans, not whole insurers, so the same insurer can sell one plan that includes Gundersen and another that doesn’t. The answer that counts is a check of your exact plan, dated. Get my free hospital check ↑
Searching for MetLife, Delta Dental or Renaissance? Those are dental insurers: dental plans cover teeth, not hospital care. If you want dental coverage too, see dental insurance for individuals.
Where Gundersen operates
Gundersen Health System is based in La Crosse, Wisconsin and serves a tri-state area reaching into southeastern Minnesota and northeastern Iowa. These are the carriers filing marketplace plans in that market for 2026, taken from the CMS landscape file:
| Market | Carriers filing | Counties with a PPO |
|---|---|---|
| La Crosse, Wisconsin | 3 | 0 of 4 |
No PPO is sold on the marketplace in any of these counties. Every plan is an HMO, EPO or POS — so if Gundersen is not in the network attached to the plan you buy, you pay most or all of the bill: an HMO or EPO pays nothing out of network except in an emergency, and a POS plan pays only part of an out-of-network bill, at a higher cost. That makes the network question decisive rather than a detail.
What is actually filed near Gundersen
Plan supply and price vary county by county, and that variation is the part a price-sorted plan list hides:
| County | Plans filed | PPO | Benchmark Silver, age 40 | Family of 4, per month |
|---|---|---|---|---|
| La Crosse County | 37 | No | $638.42 | $2,041 |
| Trempealeau County | 44 | No | $638.42 | $2,041 |
| Vernon County | 46 | No | $657.86 | $2,103 |
| Monroe County | 37 | No | $698.51 | $2,233 |
Every plan filed in these counties for 2026 is a restricted network — HMO, EPO or POS. There is no PPO to fall back on, so if Gundersen is outside the network attached to the plan you buy, there is no out-of-network benefit. Which plan you pick decides whether your hospital is covered.

PY2026 CMS filed data. Benchmark Silver is for a 40-year-old; the family figure is a four-person household before any premium tax credit. Your own premium depends on age, household, tobacco use and the credit you qualify for. Verify at enrollment.
How many providers each insurer lists near Gundersen
Every insurer selling marketplace plans has to publish its provider directory as a data file. I counted the doctors, clinics and hospitals each one lists at an address in each county below, across the 2026 plans it filed there. A dash means the insurer does not sell in that county.
| Insurer | La Crosse County | Trempealeau County | Vernon County | Monroe County |
|---|---|---|---|---|
| Anthem Blue Cross and Blue Shield | 1,839 | — | 264 | 528 |
| Medica | 1,474 | 780 | 193 | 605 |
| Quartz | 1,173 | 169 | 240 | 311 |
| Security Health Plan | — | 376 | — | — |
| Dean Health Plan | — | — | not counted | — |
Dean Health Plan: its directory file refused the download.
From each insurer’s own CMS machine-readable provider directory, downloaded September 25, 2026. A bigger number is not a promise about Gundersen. These files are self-reported, they go stale, and one insurer’s plans do not all use the same network — which is why I check the exact plan against Gundersen by hand above.
Self-employed and need Gundersen covered?
Yes, but the buying problem is different. A self-employed or 1099 household has no employer plan to fall back on and no HR department to check the network, so confirming that Gundersen is in the specific plan you buy is entirely on you. You are buying in the individual market, and in La Crosse County and Vernon County there is no PPO on the marketplace at all. Every on-exchange plan is a restricted network, so there is little out-of-network benefit to absorb a mistake: an EPO or HMO pays nothing out of network except in an emergency, and a POS plan pays only part of an out-of-network bill, at a higher cost. If Gundersen sits outside the network attached to the plan you pick, that is simply the year you have bought.
The numbers above the table are what that looks like here. Benchmark Silver for a 40-year-old in La Crosse County runs $638 a month, and a four-person household $2,041 — about $24,494 a year with no credit against it. In Vernon County it is $658, so which side of a county line you live on changes the number by $233 a year.
The second problem is that your income is a guess. Premium tax credits are calculated on what you project to earn next year — a number a 1099 earner, contractor or commission-paid household genuinely does not know in November. Above 400% of the federal poverty level there is no cap on repaying an advance credit, so a strong December can cost more than it earned. If your income moves, update the estimate on your exchange during the year rather than setting it once.
The mechanics of both — how the credit reconciles, and how to claim the self-employed premium deduction so an S-corp does not lose it — are the same wherever you live, so they live in one place rather than being repeated here: the self-employed premium deduction and subsidy reconciliation →
Two things decide your year here: whether Gundersen is in the network of the specific plan you buy, and whether your income estimate holds. Getting the first wrong costs you access to the hospital; getting the second wrong costs you a bill in April.

The tri-state catch
Gundersen’s service area crosses three states. Marketplace plans do not. A plan is sold, priced and networked by the county you live in, so if you live in Minnesota or Iowa and drive to La Crosse for care, the question is not whether Gundersen is in your carrier’s networks generally — it is whether the plan you bought in your home county treats a Wisconsin facility as in-network.
That is the most common way people here get caught. A plan can price well and cover a hospital forty minutes away while treating the system you actually use as out-of-network, purely because it sits over a state line. If you cross a border for care, say so out loud when you compare plans.
One practical note when you search a directory: Gundersen has been through organisational changes in recent years, and directories do not always update branding at the same pace. If a search returns nothing, try the parent or successor entity name before concluding the facility is not covered.
Why nobody can give you a straight list
A carrier is not a network. The same insurer sells a broad-network plan and a narrow one side by side in the same county, and Gundersen can be contracted with one and not the other. A page telling you “Gundersen accepts Carrier X” is describing one plan on one date, and usually states neither.
Contracts are renegotiated mid-year too. A system and an insurer can part company in March, and patients usually find out from a letter afterwards. That is why the only answer worth having is one dated to when it was checked.
How to settle it for your plan
- Get the exact plan name and network name from your marketplace listing, not just the carrier.
- Search that network in the carrier’s own provider directory, set to the correct plan year.
- Call Gundersen billing and read them the plan name. They will tell you whether they are contracted. This is the step that actually decides it.
- Check your individual physicians separately — anaesthesia, radiology and pathology are frequently contracted apart from the hospital.
- Note the date and who confirmed it.
