If you live in Tennessee and need health insurance, the Affordable Care Act (ACA) provides access to comprehensive coverage through the federal marketplace at HealthCare.gov. Nearly 643,000 Tennesseans enrolled in ACA marketplace plans in 2025, and the program continues to be a vital source of health coverage for individuals and families across the state. Whether you are self-employed, between jobs, or simply looking for affordable coverage, understanding Tennessee ACA benefits and coverage can help you find the right plan and save money on premiums and out-of-pocket costs.
Tennessee uses the federal marketplace rather than operating its own state exchange. Six private insurers offer plans across the state for 2026, though availability varies by region. This guide walks you through everything you need to know about enrolling, what benefits are covered, income limits for financial assistance, and how to get help.
Essential Health Benefits in Tennessee ACA Plans
All ACA marketplace plans in Tennessee must cover 10 categories of essential health benefits. This means every plan, regardless of the metal tier you choose (Bronze, Silver, Gold, or Platinum), includes the following:
- Ambulatory patient services (outpatient care you receive without being admitted to a hospital)
- Emergency services (emergency room visits)
- Hospitalization (inpatient care when you are admitted to a hospital)
- Maternity and newborn care (pregnancy, labor, delivery, and newborn baby care)
- Mental health and substance use disorder services (including behavioral health treatment and counseling)
- Prescription drugs
- Rehabilitative and habilitative services and devices (services and devices to help people with injuries, disabilities, or chronic conditions)
- Laboratory services (blood tests, screenings, and other lab work)
- Preventive and wellness services and chronic disease management (including vaccinations, screenings, and check-ups at no extra cost)
- Pediatric services (including dental and vision care for children)
Beyond these required benefits, many Tennessee marketplace plans also offer additional coverage for adult dental care, vision services, and other extras. Preventive care services like annual physicals, immunizations, and certain cancer screenings are covered at no cost to you when you see an in-network provider.
ACA Plan Metal Tiers Explained
Tennessee marketplace plans come in four metal tiers, each with a different balance between monthly premiums and out-of-pocket costs:
| Metal Tier | Actuarial Value | Monthly Premium | Out-of-Pocket Costs |
|---|---|---|---|
| Bronze | 60% | Lowest | Highest |
| Silver | 70% | Moderate | Moderate |
| Gold | 80% | Higher | Lower |
| Platinum | 90% | Highest | Lowest |
Silver plans are often the best value for Tennesseans who qualify for cost-sharing reductions (CSR). These reductions lower your deductibles, copays, and maximum out-of-pocket expenses, but they only apply to Silver-tier plans.
Income Limits and Financial Assistance for 2026
One of the biggest advantages of the ACA is financial help to make coverage affordable. In Tennessee, two types of assistance are available through the marketplace.
Premium Tax Credits
Premium tax credits lower your monthly insurance payment. For 2026, the enhanced subsidies that were in place from 2021 through 2025 have expired. The subsidy cliff has returned, meaning financial assistance is now available only to households with incomes between 100% and 400% of the federal poverty level (FPL).
Important for Tennessee: Because Tennessee has not expanded Medicaid, adults earning below 100% FPL who do not qualify for TennCare may fall into the "coverage gap," where they earn too little for marketplace subsidies but too much for traditional Medicaid. This affects an estimated 95,000 or more Tennesseans.
2026 Income Limits for ACA Premium Subsidies (48 Contiguous States)
| Household Size | 100% FPL (Minimum) | 400% FPL (Maximum) |
|---|---|---|
| 1 | $15,060 | $60,240 |
| 2 | $20,440 | $81,760 |
| 3 | $25,820 | $103,280 |
| 4 | $31,200 | $124,800 |
| 5 | $36,580 | $146,320 |
| 6 | $41,960 | $167,840 |
Income limits are based on 2025 federal poverty guidelines used for 2026 plan year eligibility.
Cost-Sharing Reductions
If your household income is at or below 250% FPL, you may also qualify for cost-sharing reductions when you choose a Silver plan. These reductions can significantly lower your deductible and out-of-pocket maximum:
| Income Level | Approximate Actuarial Value |
|---|---|
| 100% to 150% FPL | 94% (Silver plan enhanced) |
| 150% to 200% FPL | 87% (Silver plan enhanced) |
| 200% to 250% FPL | 73% (Silver plan enhanced) |
This means a Silver plan at the lowest income tier covers roughly 94% of your medical costs, compared to the standard 70%.
The Tennessee Coverage Gap
Tennessee has not expanded Medicaid under the ACA. The state operates TennCare, its traditional Medicaid program, which covers children, pregnant women, parents and caretakers with dependent children, and elderly or disabled individuals. However, non-disabled adults without dependent children are not eligible for TennCare regardless of how low their income is.
This creates a coverage gap. If you are a non-disabled adult without children and your income is below 100% FPL (about $15,060 per year for an individual), you likely do not qualify for either TennCare or ACA marketplace subsidies.
If you fall into this gap, some options to explore include:
- Community health centers that offer sliding-scale fees based on income
- Tennessee 211 (dial 2-1-1) for referrals to local free or low-cost health services
- Hospital charity care programs at many Tennessee hospitals
- CoverRx, a limited prescription assistance program for uninsured Tennesseans

How to Enroll in an ACA Plan in Tennessee
Follow these steps to sign up for marketplace coverage in Tennessee:
Step 1: Gather Your Information
Before you start, have the following ready:
- Social Security numbers for everyone in your household
- Employer and income information (pay stubs, W-2 forms, or tax returns)
- Current health insurance policy numbers (if applicable)
- Immigration documents (if not a U.S. citizen)
Step 2: Visit HealthCare.gov
Tennessee uses the federal marketplace. Go to HealthCare.gov to create an account or log in if you already have one.
Step 3: Complete Your Application
Answer questions about your household size, income, and current coverage. The system will determine if you qualify for premium tax credits, cost-sharing reductions, TennCare, or CoverKids (Tennessee's CHIP program for children).
Step 4: Compare Plans
Browse available plans in your area. Tennessee has six insurers offering marketplace plans for 2026, though options vary by county. Compare premiums, deductibles, provider networks, and covered medications.
Step 5: Select and Enroll
Choose the plan that best fits your needs and budget. Confirm your enrollment and pay your first monthly premium to activate coverage.
Step 6: Use Your Coverage
Once enrolled, you will receive your insurance card and can begin using your benefits. Schedule preventive care appointments and familiarize yourself with your plan's provider network.
Open Enrollment and Special Enrollment Periods
Open Enrollment for 2026 plans typically runs from November 1 through January 15. If you enroll by December 15, your coverage starts January 1. Enrollments made between December 16 and January 15 have coverage starting February 1.
Outside of open enrollment, you may qualify for a Special Enrollment Period (SEP) if you experience a qualifying life event such as:
- Losing existing health coverage (job loss, aging off a parent's plan)
- Getting married or divorced
- Having or adopting a child
- Moving to a new area with different plan options
- Changes in household income that affect eligibility
You generally have 60 days from the qualifying event to enroll through a Special Enrollment Period.

Six insurance companies offer marketplace plans in Tennessee for the 2026 plan year:
- Ambetter from TennCare Select (Celtic/Centene)
- BlueCross BlueShield of Tennessee
- Bright Health

Plan availability depends on where you live in Tennessee. Urban areas like Nashville, Memphis, Knoxville, and Chattanooga generally have more plan options, while rural counties may have fewer choices.
TennCare and CoverKids: Other Coverage Options
If your income is very low or you have children, you may qualify for state-funded health coverage rather than a marketplace plan.
TennCare (Tennessee Medicaid)
TennCare covers specific populations:
| Category | Income Limit |
|---|---|
| Infants (0 to 1) | 195% FPL |
| Children (1 to 5) | 142% FPL |
| Children (6 to 18) | 133% FPL |
| Pregnant women | 250% FPL |
| Parents/caretakers | 105% FPL |
Apply through TennCare Connect at 855-259-0701 or through HealthCare.gov. When you apply on the marketplace, the system will automatically check your TennCare eligibility.
CoverKids (CHIP)
CoverKids provides health coverage for uninsured children under 19 with family incomes up to 211% to 255% FPL. The program has no premiums, and copays are capped at 5% of annual household income.

Many Tennesseans who qualify for ACA subsidies or TennCare may also be eligible for additional assistance programs. These include:
- SNAP (food assistance) for households with income up to 130% FPL
- LIHEAP (energy bill assistance) for households with income up to 60% of state median income
- WIC (nutrition program) for pregnant women, new mothers, and children under 5
