“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.”

How the check works: a licensed agent checks Marshfield Clinic Health System, and any doctors you name, against every 2026 marketplace plan filed in your county, then sends you the plans that include them and the date it was checked. It costs nothing, and you only get a call if you ask for one.

  3. Your answer, usually the same day

Open Enrollment for 2027 runs November 1 to January 15: choose by December 15 for coverage from January 1. CareSource is leaving Ohio’s marketplace for 2027. If your plan is from CareSource, it ends December 31, and the plan that replaces it may not include Marshfield Clinic Health System. A licensed agent will check the 2027 plans for you before you choose.

Marshfield Clinic Health System runs 8 hospitals in Wisconsin, in Beaver Dam, Eau Claire, Ladysmith, Marshfield and 4 more. Whether a marketplace plan covers any one of them depends on the individual plan, not on the carrier's name, and it can change during the year. Here is what is actually knowable, and how to settle it for your own plan.

Insurance at Marshfield Clinic Health System: the short answer

These 6 insurers sell 2027 marketplace plans in the 8 counties it serves: Anthem Blue Cross and Blue Shield, Medica, Security Health Plan, Aspirus Health Plan, Dean Health Plan and Quartz.

That is not a list of plans Marshfield Clinic Health System accepts. Hospitals contract with individual plans, not whole insurers, so the same insurer can sell one plan that includes Marshfield Clinic Health System 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.

CMS star rating is the federal overall hospital quality rating, 1 to 5, from the same July 2026 CMS file. Small rural (critical access) hospitals often have too few reported measures to be rated.

Why no page can promise your plan covers Marshfield Clinic Health System

Hospital networks are set plan by plan and renegotiated during the year. Two plans from the same insurer, at similar prices, can differ on whether a hospital is in network. Nothing in the public CMS files records hospital contracts, so any page listing "insurers Marshfield Clinic Health System accepts" is describing one plan on one day, and not saying which.

What is knowable is the shape of the market: 6 insurers file 205 plans across the 8 counties below, and every plan filed in Clark County for 2027 is a restricted network — EPO, HMO, POS — so out-of-network care is limited: an EPO or an HMO pays only for emergencies, and a POS pays part of an out-of-network bill.

Three checks settle it for your own plan: the insurer’s own provider directory for the exact plan name, the hospital’s billing office (ask about the plan, not the carrier), and the date you checked, because the answer can change mid-year.

How many providers each insurer lists in Barron County

Every insurer selling marketplace plans has to publish its provider directory as a data file. The figures count the doctors, clinics and hospitals each one lists at an address in Barron County, across the 2026 plans it filed there. Medica lists the most, 1,353. Security Health Plan lists the fewest, 790.

InsurerProviders listed in Barron CountyPlans filed
Medica1,35312
Anthem Blue Cross and Blue Shield8819
Security Health Plan79016

From each insurer’s own CMS machine-readable provider directory, downloaded September 25, 2026. A bigger number is not a promise about Marshfield Clinic Health System. These files are self-reported, they go stale, and one insurer’s plans do not all use the same network — which is why a licensed agent checks the exact plan against Marshfield Clinic Health System by hand above.

Open Enrollment 2027

Molina is leaving Wisconsin's marketplace for 2027, and Open Enrollment runs 1 November 2026 to 15 January 2027. If your 2026 plan is from Molina, the plan that replaces it is a different plan with its own network. A licensed agent can check Marshfield Clinic Health System, and any doctors you name, against the plans filed in your county and send you the ones that include them, with the date it was checked.

Emergency care is treated differently

8 of these locations run an emergency room. Federal law requires marketplace plans to cover emergency care at in-network cost sharing even when the hospital is out of network, so an emergency visit is not the case to worry about. Planned surgery, imaging, maternity and specialist follow-up are where the network matters.
