Hundreds of thousands of Tennesseans lack health coverage, a number that reflects in part the state’s decision not to expand Medicaid under the Affordable Care Act, according to estimates from the Kaiser Family Foundation. Finding affordable health insurance in Tennessee means navigating a Marketplace that varies significantly by region, with some rural counties offering just one or two carriers. Still, premium tax credits and the state’s CoverKids program provide meaningful help for many residents.
This guide breaks down Tennessee’s Marketplace landscape, typical costs, plan options, and enrollment steps so you can make a well-informed decision. Because prices, carriers, and subsidy rules change from year to year, confirm the current details at HealthCare.gov before you enroll. For broader context on how state and federal policies shape insurance access, see our healthcare policy guide.
Tennessee’s Health Insurance Marketplace
Tennessee relies on the federal Health Insurance Marketplace at HealthCare.gov for individual and family plan enrollment. The state does not operate its own exchange. Residents in Nashville, Memphis, Knoxville, and Chattanooga typically have more carrier choices than those in rural East or West Tennessee. Free help is available by phone through the Marketplace call center at 1-800-318-2596.
Carriers on the Tennessee Marketplace have included BlueCross BlueShield of Tennessee, Cigna Healthcare, Oscar Health, Ambetter, and others, with participation varying by county and changing over time. BlueCross BlueShield of Tennessee has historically been the most widely available carrier. Because insurer participation shifts each year, check HealthCare.gov to confirm which carriers and plans serve your county for the current plan year.
Competition among insurers has improved in many areas in recent years, which has helped moderate premium increases. However, plan networks vary considerably. Some of the lowest-premium options use narrow networks that restrict your choice of hospitals and specialists, so checking provider directories before enrolling is essential.
Plan Types and Metal Tiers Available
Marketplace plans in Tennessee follow the standard ACA metal tier structure. Each tier reflects how costs are split between you and the insurer, on average.
- Bronze: Lowest premiums, highest out-of-pocket costs. The insurer covers roughly 60% of average expenses, and deductibles are often high.
- Silver: Moderate premiums with roughly 70% cost coverage. Silver plans are the gateway to cost-sharing reductions for lower-income enrollees.
- Gold: Higher premiums but lower deductibles and copays. The insurer covers about 80% of costs.
- Platinum: Highest premiums, lowest out-of-pocket expenses, covering approximately 90% of costs (not offered in every area).
Catastrophic plans remain available for those under 30 or with a hardship or affordability exemption, offering very low premiums paired with high deductibles.
Average Premiums and Costs
Premiums vary by age, county, plan, and tobacco use, and they change every year, so treat any figure as an estimate and confirm current pricing at HealthCare.gov. Historically, benchmark Silver premiums for a 40-year-old in Tennessee have run in the mid-hundreds of dollars per month before subsidies, with Bronze plans lower and Gold plans higher. After premium tax credits, many enrollees pay substantially less, and lower-income enrollees in metro areas have often found subsidized Silver plans for a modest monthly amount.
Deductibles in Tennessee generally track national averages, with Bronze plans carrying the highest deductibles and Silver plans somewhat lower, especially when cost-sharing reductions apply. For 2026, the federal out-of-pocket maximum for Marketplace plans is $10,600 for an individual and $21,200 for a family, according to HealthCare.gov. This cap limits what you pay for covered, in-network essential health benefits in a year; individual plans may set lower limits.
TennCare and the Medicaid Coverage Gap
Tennessee has not expanded Medicaid under the ACA. The state’s Medicaid program, TennCare, covers specific categories of low-income residents: children, pregnant women, parents or caretakers with very low incomes, seniors, and individuals with disabilities. Childless adults generally do not qualify regardless of income. TennCare operates under a long-standing federal waiver, and its financing and rules have been the subject of ongoing policy debate, including block-grant-style arrangements.
This creates what is known as the coverage gap. Adults earning below 100% of the federal poverty level often earn too much for TennCare but too little to qualify for Marketplace subsidies, which generally begin at 100% of the poverty level. An estimated tens of thousands of Tennesseans fall into this gap. If you are among them, community health centers and hospital charity care programs may be your primary options for affordable care.
Several legislative proposals have attempted to address this issue over the years, but as of 2026 Tennessee has not adopted full Medicaid expansion. Check TennCare directly for the most current eligibility rules, as these can change.
CoverKids: Tennessee’s CHIP Program
CoverKids is Tennessee’s Children’s Health Insurance Program (CHIP), providing coverage for children and pregnant women in families that earn too much for standard TennCare but cannot easily afford private coverage. Children in families with household incomes up to roughly 250% of the federal poverty level may qualify; verify the current income limit with the state, as thresholds are updated periodically.
CoverKids provides comprehensive benefits including doctor visits, immunizations, dental care, vision services, hospital stays, mental health treatment, and prescription medications. Costs to families are low, and enrollment is open year-round. Applications can be submitted through TennCare’s CoverKids page or by phone; processing times vary.
Subsidies and Financial Assistance
Premium tax credits are available to Tennessee residents purchasing Marketplace plans who meet income and eligibility rules, generally starting at 100% of the federal poverty level. In recent years, enhanced subsidies also capped premiums at 8.5% of household income for many enrollees above 400% of the poverty level and lowered costs across the board.
Important 2026 note: those enhanced subsidies were scheduled to expire at the end of 2025. Whether they are extended depends on federal legislation. If they lapse, some enrollees — particularly those just above 400% of the poverty level — could see notably higher net premiums, and the income cliff at 400% could return. Because this directly affects what you pay, check your personalized estimate at HealthCare.gov during enrollment rather than relying on last year’s figures.
Cost-sharing reductions further lower out-of-pocket costs for Silver plan enrollees earning between 100% and 250% of the poverty level, reducing deductibles, copays, and maximum out-of-pocket limits without raising your premium. Federal poverty guidelines are updated annually, so use the HealthCare.gov subsidy calculator for current, income-specific estimates.

How to Enroll in Health Insurance in Tennessee
Open Enrollment for federal Marketplace coverage has generally run from November 1 through January 15, with plans selected by mid-December starting January 1 and later selections starting the following month. Exact dates can change, so confirm the window for the upcoming plan year at HealthCare.gov.
To enroll, visit HealthCare.gov and create or log into your account. You will need documentation such as Social Security numbers for household members, income verification (W-2s, pay stubs, or tax returns), and current insurance information if applicable.
Special Enrollment Periods allow enrollment outside the standard window if you experience qualifying events:
- Loss of employer-sponsored or government coverage
- Marriage, divorce, or legal separation
- Birth or adoption of a child
- Permanent move to a new coverage area
- Certain changes in income or immigration status
Tennessee has a network of certified navigators and insurance agents who offer free enrollment assistance. Organizations connected with the Tennessee Department of Health and community health centers across the state can help you apply and compare plans.
Employer-Sponsored and Short-Term Plans
Most insured Tennesseans get coverage through an employer. If your employer offers a plan that meets minimum value and affordability standards under ACA rules (the affordability percentage is set by the IRS and adjusted annually), you generally will not qualify for Marketplace subsidies. Check the current threshold when weighing your options.
Short-term health insurance is sometimes available in Tennessee, but federal rules on the maximum duration of these plans have changed in recent years, so availability and terms vary. These plans skip many ACA protections — they can deny coverage for pre-existing conditions and exclude essential health benefits like maternity care or mental health treatment. Premiums are lower, but the coverage is thinner and can leave large gaps. Understanding the different types of health insurance helps clarify whether a short-term plan fits your situation, and for most people a subsidized Marketplace plan offers far stronger protection.
Frequently Asked Questions
Has Tennessee expanded Medicaid?
No. Tennessee has not expanded Medicaid under the ACA. TennCare covers children, pregnant women, certain parents, seniors, and people with disabilities, but childless adults generally do not qualify. This leaves a coverage gap for some low-income residents.
How much does health insurance cost in Tennessee?
Costs vary by county, age, plan, and income, and they change each year. Before subsidies, benchmark Silver premiums have typically run in the mid-hundreds of dollars per month for a 40-year-old; with premium tax credits, many enrollees pay much less. Use HealthCare.gov for a personalized estimate.
What is CoverKids in Tennessee?
CoverKids is Tennessee’s CHIP program, providing health coverage for eligible children and pregnant women in families with incomes up to about 250% of the federal poverty level. It covers medical, dental, vision, and mental health services at low or no cost, and enrollment is year-round.
Can I buy health insurance outside of open enrollment in Tennessee?
Marketplace coverage is available outside Open Enrollment only if you qualify for a Special Enrollment Period due to a life event such as losing coverage, getting married, having a baby, or moving. TennCare and CoverKids accept applications year-round.
Which insurance companies offer Marketplace plans in Tennessee?
BlueCross BlueShield of Tennessee has been the most widely available carrier, with others such as Cigna, Oscar Health, and Ambetter offered in various counties. Availability changes annually and by location, and metro areas typically have more options. Confirm current carriers at HealthCare.gov.
Please verify before you enroll: This article is general educational information, not insurance, legal, or tax advice. Plan availability, premiums, subsidy rules (including whether enhanced premium tax credits continue for 2026), out-of-pocket limits, and eligibility thresholds change from year to year. Confirm your specific options, costs, and eligibility at HealthCare.gov or with a licensed broker or certified navigator, and check TennCare and CoverKids details with the State of Tennessee before making decisions.
The Bottom Line
Navigating health insurance in Tennessee takes more effort than in states with expanded Medicaid or state-run exchanges, but affordable options exist for most residents. Premium tax credits make Marketplace plans accessible for many households, and CoverKids fills a critical gap for families with children. If your income falls into the coverage gap, community health centers and hospital financial assistance programs may provide a safety net.
Compare plans carefully during Open Enrollment, paying attention not just to premiums but to deductibles, provider networks, and prescription drug coverage. A plan that saves a little each month but excludes your doctors or medications may end up costing far more over the course of a year — and always confirm current costs and subsidy rules at HealthCare.gov.
