2026 rate changes by carrier

All six carriers raised rates for 2026, but by very different amounts. These are the final approved full-price rate changes, before any premium tax credit is applied:

Weighted statewide average: +37.5%. A carrier's rate change applies to its full lineup on average — individual plans within that carrier's portfolio can move by more or less than the figure shown. See our full plan-type comparison for what these tiers mean for your actual deductible and copays.

HMO vs. PPO: which matters more in Tennessee?

Most Tennessee ACA plans are HMOs (Health Maintenance Organizations), which require you to use an in-network primary care provider and get referrals for specialists, in exchange for lower premiums. PPOs (Preferred Provider Organizations) cost more but allow more flexibility to see out-of-network providers without a referral.

In large metro areas like Nashville, Memphis, and Knoxville, HMO networks are usually broad enough that the lower premium makes sense for most people. In more rural counties with fewer contracted providers, a PPO's flexibility can be worth the extra cost.

Regional carrier strength

Carrier presence in Tennessee varies by region. Blue Cross Blue Shield of Tennessee, headquartered in Chattanooga, has the broadest statewide reach and is active in all 95 counties. Cigna Healthcare has strong urban presence around its Nashville-area footprint, while Ambetter and Oscar Health tend to concentrate coverage around Middle and East Tennessee's larger metros. UnitedHealthcare and Alliant Health Plans round out the market with more selective county-by-county participation. This regional variation is exactly why the same plan name can mean a very different network depending on which Tennessee county you're shopping in.

How to actually compare two plans

Premium is only one piece of the comparison. Two plans with a similar monthly cost can have very different deductibles, copay structures, and out-of-pocket maximums, so it's worth lining up all three side by side rather than picking based on premium alone. It's also worth checking whether a plan uses a narrow network built around a specific hospital system, which can mean lower costs but fewer choices if you ever need to switch providers. See our Bronze vs. Silver vs. Gold vs. Platinum comparison for how metal tier changes that premium-vs-deductible tradeoff.

Checking your prescription coverage

Each carrier maintains its own drug formulary — the list of covered medications and what tier (and therefore what copay) they fall into. A medication covered cheaply on one carrier's formulary might sit on a much higher, more expensive tier with a different carrier, even at the same metal level. If you take regular prescriptions, checking the formulary before enrolling is one of the highest-value things you can do to avoid a surprise cost later.

On-exchange vs. off-exchange plans

Most carriers sell both "on-exchange" plans (available through HealthCare.gov, where premium tax credits can be applied) and "off-exchange" plans (bought directly from the carrier or through an agent outside the Marketplace). Off-exchange plans are never eligible for a premium tax credit, even if the plan itself looks identical to an on-exchange option, so unless you're certain you won't qualify for any subsidy, it's almost always worth starting your search on-exchange.

Matching a carrier to your health needs

Someone who's generally healthy and rarely visits a doctor may prioritize the lowest premium above all else, while someone managing an ongoing condition may find it worth paying more for a plan with a stronger specialist network or better prescription coverage for their specific medications. There's no single "best" carrier in Tennessee — the right one depends entirely on your own health situation, budget, and which providers you want to keep seeing.
