Which Insurers Are Leaving Tennessee’s Marketplace in 2027?

Published September 1, 2026 · Daniel Griffin, Licensed Independent Advisor · NPN #22052447

Cigna stops selling individual marketplace plans in Tennessee on January 1, 2027. Tennessee is one of the eleven states in that announcement, and it is one of the more consequential ones — Cigna sold in 65 of Tennessee’s 95 counties.

The good news first, because it is real: Tennessee is not losing access. The bad news is that access and choice are different things, and in most of the state this exit costs you the second one.

Who Is Left in Tennessee

Tennessee went into 2026 with six marketplace carriers. Three of them — Ambetter of Tennessee, UnitedHealthcare and BlueCross BlueShield of Tennessee — sell in all 95 counties. Those three are staying. That is why nobody in Tennessee will be left without a marketplace option in 2027.

But the two carriers beyond that trio are thin on the ground. Oscar reaches fewer than half of Tennessee’s counties and Alliant reaches about a tenth of them. So once Cigna is gone, a large share of the state is choosing among three carriers rather than four or five — and in the rural counties Oscar and Alliant never entered, three is the whole list.

If you live in Nashville, Memphis, Knoxville or Chattanooga you will still have a real comparison to make. If you live between them, this exit narrows your field more than the statewide carrier count suggests.

The Risk Here Is Your Network, Not Your Access

Because three carriers cover the entire state, Tennessee will not see the scramble that states losing their only regional insurer are facing. What Tennessee will see is a network reshuffle across two-thirds of its counties at once.

A Cigna network and a BlueCross network are not the same network. When a plan that covered 65 counties disappears, the specialists, hospitals and drug formularies that came with it disappear with it — for everyone who had it, in the same month.

What Happens Automatically, and Why It Catches People

Your Cigna plan runs through December 31, 2026. You are not dropped mid-year. At open enrollment the exchange will try to move you automatically into a plan from a remaining carrier.

That auto-enrollment matches on metal tier and price. It does not match on your doctors or your prescriptions. People who let it happen routinely find out in February that the specialist they have seen for years is out of network — and by then the window to change has closed.

In a state where one carrier is handing off two-thirds of the counties simultaneously, that is not a rare edge case. Treat this open enrollment as an active decision, not a renewal.

Tennessee Squeezes You From Both Ends

Two things are true in Tennessee that are not true everywhere, and together they matter more than the carrier count.

Tennessee has not expanded Medicaid. Adults earning below the federal poverty level can fall into a coverage gap — too much income for TennCare, too little for premium tax credits, which do not begin until 100% of poverty. If your income is near that line, estimating it accurately is the single highest-value thing you can do before you shop.

And above the line, the credit now ends abruptly. The enhanced subsidy schedule expired on December 31, 2025. Above 400% of the federal poverty level — about $62,600 for one person — the credit does not shrink, it stops. There is no taper.

So Tennessee residents can be too poor for a credit and too well-paid for one, and the distance between those two positions is smaller than most people assume. Check where you fall against the cliff →

What To Do in Tennessee

1. Confirm your carrier is actually Cigna. It is on your ID card, and it is not always the name you remember signing up with.
2. Write down your doctors and prescriptions first, then check them against the carriers still selling in your county — not the other way round.
3. Check what is actually offered where you live. Tennessee’s remaining carriers are not evenly distributed, and your county is what decides your list.
4. Re-run your subsidy on your 2027 income, not your 2025 one.
5. Do not auto-renew. With Cigna gone, last year’s equivalent plan may not exist in your county at all.

If You Are Above the Subsidy Line, This Is a Different Decision

Most advice about a carrier leaving quietly assumes a premium tax credit is absorbing the replacement cost. If your household is above 400% of poverty, nothing is absorbing it.

Marketplace plans charge everyone your age the same price regardless of health, because insurers there are not permitted to ask. That protection is the entire point of the marketplace — and if you are healthy and receiving no credit, you are paying for it and getting nothing back. A medically underwritten plan sold outside the exchange asks health questions and prices on the answers, and for a healthy household it often comes in lower.

If anyone in your household has a meaningful health history, stay on the marketplace. Guaranteed issue is worth exactly what it costs you. But if you are healthy, above the line, and losing your Cigna plan anyway, this is the year to price both markets rather than one. How the two markets compare →
