“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 Ascension Saint Thomas, 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.
- Your ZIP code
- Who to check — Ascension Saint Thomas is filled in
- 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. Cigna is leaving Tennessee’s marketplace for 2027. If your plan is from Cigna, it ends December 31, and the plan that replaces it may not include Ascension Saint Thomas. A licensed agent will check the 2027 plans for you before you choose.
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.
Insurance at Ascension Saint Thomas: the short answer
These 5 insurers sell 2026 marketplace plans in the 6 counties it serves: Ambetter of Tennessee, BlueCross BlueShield of Tennessee, Cigna Healthcare (leaving after 2026), Oscar Insurance Company and UnitedHealthcare.
That is not a list of plans Ascension Saint Thomas accepts. Hospitals contract with individual plans, not whole insurers, so the same insurer can sell one plan that includes Ascension Saint Thomas and another that doesn’t. The answer that counts is a check of your exact plan, dated. Get my free hospital check ↑

Where Ascension Saint Thomas operates
Ascension Saint Thomas serves Nashville, Murfreesboro, Centerville, Sparta, Waverly, McMinnville in Tennessee. These are the carriers filing marketplace plans in those markets for 2026, taken from the CMS landscape file:

What is actually filed near Ascension Saint Thomas
Plan supply and price vary county by county, and that variation is exactly what a price-sorted plan list hides:
| County | Market | Plans filed | PPO | Benchmark Silver, age 40 | Family of 4, per month |
|---|---|---|---|---|---|
| Davidson County | Nashville | 65 | No | $752 | $2,406 |

Every plan filed in Davidson County for 2026 is an EPO — a restricted network. There is no PPO to fall back on, so if Ascension Saint Thomas 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.

How many providers each insurer lists near Ascension Saint Thomas
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 each county below, across the 2026 plans it filed there. A dash means the insurer does not sell in that county.
| Insurer | Davidson County | Hickman County | Humphreys County | Rutherford County |
|---|---|---|---|---|
| Oscar Insurance Company | 14,300 | 232 | 380 | 4,572 |
| Cigna Healthcare (leaving this marketplace for 2027) | 12,466 | — | — | 4,751 |
| BlueCross BlueShield of Tennessee | 11,573 | 150 | 171 | 3,726 |
| Ambetter of Tennessee | 5,207 | 122 | 173 | 2,377 |
| UnitedHealthcare | 4,638 | 109 | 108 | 2,054 |
From each insurer’s own CMS machine-readable provider directory, downloaded September 25, 2026. A bigger number is not a promise about Ascension Saint Thomas. 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 Ascension Saint Thomas by hand above.
Self-employed and need Ascension Saint Thomas 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 Ascension Saint Thomas is in the specific plan you buy is entirely on you. You are buying in the individual market, and in Davidson County there is no PPO on the marketplace at all. Every on-exchange plan is a restricted network, so there is no out-of-network benefit to absorb a mistake. If Ascension Saint Thomas 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 Davidson County runs $752 a month, and a four-person household $2,406 — about $28,870 a year with no credit against it.
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 Ascension Saint Thomas 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.
Want cheaper coverage? Want better coverage? Not happy with what you have now? Same next step for all three — send your ZIP and the doctors you need covered, and a licensed agent will check Ascension Saint Thomas against every plan filed in your county.
The Ascension Saint Thomas hospitals in Tennessee
7 facilities, from the CMS Hospital General Information file (updated 22 July 2026). Listing them is not a statement about which plans contract with them — that is decided plan by plan.

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 Ascension Saint Thomas can be contracted with one and not the other. A page telling you “Ascension Saint Thomas 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 Ascension Saint Thomas 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.
