Most Tennessee residents looking for health insurance end up choosing between two systems: TennCare (the state's Medicaid program) and the HealthCare.gov marketplace. They look similar from the outside — both have free or low-cost coverage, doctor networks, and prescription benefits — but the eligibility rules, networks, and out-of-pocket costs are dramatically different.
This guide is grounded in current CMS and KFF data for Tennessee. We update it whenever federal poverty guidelines change (typically January) or when Tennessee's Department of Insurance issues new bulletins.

The Short Answer
TennCare: How It Works in Tennessee
TennCare is jointly funded by the federal government and the State of Tennessee, administered by the state. It's the same federal program you've heard of as "Medicaid," just rebranded with a state-specific name (Tennessee's version is called TennCare).
Who qualifies in Tennessee:
- Pregnant women up to 200%+ FPL
- Children under 19 up to ~250% FPL (often rebranded under CHIP)
- Adults with disabilities receiving SSI
- Parents of dependent children at very low income limits (varies)
- Seniors with limited income who qualify for nursing-home care or HCBS waivers
- Note: Tennessee did not expand Medicaid to non-disabled adults under 138% FPL. Working adults without children typically don't qualify regardless of income.
What it costs: $0 monthly premium for most enrollees. Small copays (often $0–$8) for doctor visits and prescriptions. No deductible. No annual out-of-pocket maximum that you'll realistically hit.
Network: TennCare contracts with managed care organizations (MCOs) like Blue Cross Blue Shield of Tennessee that handle the day-to-day administration. Provider networks are typically robust in major metros (Nashville) and thinner in rural counties.
HealthCare.gov Marketplace Plans: How They Work
HealthCare.gov is Tennessee's federally-run health insurance marketplace under the Affordable Care Act. You pick a plan from one of 4 private carriers (Blue Cross Blue Shield of Tennessee, Cigna, Oscar, etc.) and the federal government pays a Premium Tax Credit directly to the insurer to lower your monthly bill.
Who qualifies: Anyone who isn't eligible for Medicare, employer coverage, or TennCare can buy a marketplace plan. Subsidies are available based on income — most Tennessee families earning between roughly $15,000 and $120,000 will qualify for some level of Premium Tax Credit.
What it costs: After subsidies, monthly premiums in Tennessee range from $0 (for very-low-income enrollees) to a few hundred dollars per month. Deductibles range from $0–$1,000 (Platinum/Gold) to $7,500+ (Bronze). The 2026 benchmark Silver plan in Nashville runs about $421/month before subsidies.
Network: Each carrier has its own network. Blue Cross Blue Shield of Tennessee typically offers the broadest network in Tennessee; smaller carriers offer narrower networks at lower premiums.

What if my income is right at the edge?
Because Tennessee didn't expand Medicaid, this "edge" is actually the coverage gap — too well-off for TennCare, too poor for marketplace PTC. Three options work: (1) increase projected annual income to over $15,060 (single) to qualify for marketplace PTC; even a part-time gig can do it; (2) look for non-income Medicaid pathways (pregnancy, disability, dependent child); (3) enroll in a short-term medical plan as a stopgap.
What if my income changes mid-year?
Income changes don't open TennCare eligibility for non-expansion-eligible adults. They do, however, change your marketplace subsidy size — log in to HealthCare.gov and report the change so your PTC adjusts before tax time.
Can I have both?
No. You're either Medicaid-eligible (and TennCare is your primary coverage) or you're not (and you use the marketplace). The exception: if a family member qualifies for TennCare (often kids, via CHIP) while parents enroll in marketplace plans, that's allowed and common.
How to Apply
For TennCare: Apply through the Tennessee Medicaid agency or via HealthCare.gov (which forwards your application to the state if you appear Medicaid-eligible). Application takes about 30 minutes online.
For HealthCare.gov: Apply at HealthCare.gov. Have last year's tax return, current pay stubs, and Social Security numbers for everyone in your household.
