“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 Williamson Medical Center, 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.

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 Williamson Medical Center. A licensed agent will check the 2027 plans for you before you choose.
Williamson Medical Center is in Franklin, Tennessee. Whether a marketplace plan covers it 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 Williamson Medical Center: the short answer
These 4 insurers sell 2027 marketplace plans in Williamson County: Ambetter of Tennessee, BlueCross BlueShield of Tennessee, Oscar Insurance Company and UnitedHealthcare.
That is not a list of plans Williamson Medical Center accepts. Hospitals contract with individual plans, not whole insurers, so the same insurer can sell one plan that includes Williamson Medical Center and another that doesn’t. The answer that counts is a check of your exact plan, dated. Get my free hospital check ↑

Where Williamson Medical Center is
One facility, taken from the CMS Hospital General Information file, updated 22 July 2026. Listing a hospital is not a statement about which plans contract with it — that is decided plan by plan.
| Hospital | City | County | Emergency room | CMS star rating | Type | Ownership |
|---|---|---|---|---|---|---|
| Williamson Medical Center | Franklin | Williamson County | Yes | 5 of 5 | Acute care | Government |
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 Williamson Medical Center
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 Williamson Medical Center accepts" is describing one plan on one day, and not saying which.
What is knowable is the shape of the market: 4 insurers file 68 plans across Williamson County, and every plan filed in Williamson County for 2027 is a restricted network — EPO — so out-of-network care is generally limited to emergencies.
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 Williamson 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 Williamson County, across the 2026 plans it filed there. Oscar Insurance Company lists the most, 5,456. UnitedHealthcare lists the fewest, 2,070.
| Insurer | Providers listed in Williamson County | Plans filed |
|---|---|---|
| Oscar Insurance Company | 5,456 | 15 |
| BlueCross BlueShield of Tennessee | 4,842 | 12 |
| Cigna Healthcare (leaving this marketplace for 2027) | 4,805 | 10 |
| Ambetter of Tennessee | 2,462 | 16 |
| UnitedHealthcare | 2,070 | 12 |
From each insurer’s own CMS machine-readable provider directory, downloaded September 25, 2026. A bigger number is not a promise about Williamson Medical Center. 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 Williamson Medical Center by hand above.
Open Enrollment 2027
Cigna is leaving Tennessee's marketplace for 2027, and Open Enrollment runs 1 November 2026 to 15 January 2027. If your 2026 plan is from Cigna, the plan that replaces it is a different plan with its own network. A licensed agent can check Williamson Medical Center, 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
1 of these location 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.
