TennCare, Tennessee's Medicaid program, covers roughly 1.4 million Tennesseans including children, pregnant women, disabled adults, and low-income parents. Losing TennCare in 2026 is a particularly stressful event because Tennessee is one of the 10 states that has not expanded Medicaid under the ACA, which means most adults below 100% FPL who lose TennCare fall into a coverage gap. The ACA Marketplace is designed for people earning between 100% and 400% FPL in 2026, which is roughly $15,960 to $63,840 per year for a single adult. Adults under 100% FPL in Tennessee who do not qualify for TennCare and cannot afford Marketplace coverage face a serious coverage gap that advocates have lobbied the state to address since 2014. Understanding exactly where your income falls against the 2026 FPL thresholds is the first step after losing TennCare, because it determines whether you go to the Marketplace, back to TennCare, or need to pursue one of the safety-net options described in this guide.
Six concrete steps follow in this guide: how to use your 90-day qualifying life event SEP window, appeal a TennCare termination, and choose between the Marketplace and re-enrollment. Tennessee's TennCare program uses stricter income limits than Medicaid expansion states: parents qualify up to approximately 100% of the Federal Poverty Level, pregnant women up to 250% FPL, and TennCare Kids covers children under 19 with age-tiered income limits. The One Big Beautiful Bill Act signed July 4, 2025 introduced new work requirements and stricter redetermination schedules affecting TennCare enrollees in 2026. A TennCare termination based on a paperwork error or disputed income can be appealed while you simultaneously apply for Marketplace coverage at healthcare.gov to prevent a coverage gap. The ACA Marketplace Open Enrollment Period for 2027 coverage begins November 1, 2026, so the 90-day SEP is the only enrollment window available to most Tennesseans who lose TennCare mid-year.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most costly mistakes Tennessee residents make after losing TennCare in 2026:
- Assuming the Marketplace 60-day SEP applies. Loss of Medicaid or CHIP (including TennCare) gives you 90 days to enroll in a Marketplace plan at healthcare.gov, not the standard 60 days that applies to most other qualifying life events.
- Not filing an appeal. TennCare terminations based on data-match errors or documents that were submitted but not logged are common in 2026 with stricter OBBBA verification rules. Always appeal within 30 days if the reason seems wrong or based on outdated information.
- Waiting for the appeal to resolve before applying for Marketplace coverage. Appeals take weeks or months. Apply for a Marketplace SEP the same day you file the appeal. If the appeal succeeds, you can cancel the Marketplace plan.
- Thinking children lose TennCare automatically when adults do. TennCare Kids eligibility is evaluated separately, with income limits that vary by child's age, and many children qualify even when adults in the same household lose TennCare. Apply for children through tenncare.tn.gov regardless of adult eligibility.
- Enrolling in a short-term health plan to fill the gap. Short-term plans sold in Tennessee are not ACA-compliant, typically exclude pre-existing conditions, and do not count as creditable coverage. An ACA Marketplace Silver plan with subsidies is almost always a better option for people with income between 100% and 400% FPL.
- Not using a free navigator. Tennessee has federally certified Marketplace navigators who can walk you through the healthcare.gov application at no cost, help calculate your projected 2026 income for subsidy purposes, and assist with TennCare appeals. Contact Tennessee Primary Care Association at (615) 726-3688 or find your local navigator at localhelp.healthcare.gov.
Tennessee Non-Expansion: Why Losing TennCare Is Different from Other States
Tennessee is one of 10 states that has not expanded Medicaid under the ACA as of 2026. That policy choice has two major consequences for people who lose TennCare. First, most working-age adults without dependent children cannot qualify for TennCare at all, regardless of income, so re-enrollment is not an option for them. Second, adults under 100% FPL in Tennessee who do not meet TennCare's categorical requirements fall into a coverage gap: they earn too little for ACA Marketplace subsidies (which start at 100% FPL) and too much, or wrong category, for TennCare. The 10 non-expansion states are Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming. In expansion states, Medicaid covers adults up to 138% FPL at $22,025 for a single person in 2026. TennCare's limits for parents are approximately 100% FPL, about $21,640 for a household of two in 2026. This gap affects approximately 140,000 Tennesseans according to KFF 2026 estimates, and losing TennCare can land a low-income adult directly in it.
Tennesseans who do qualify for TennCare re-enrollment can apply year-round through tenncare.tn.gov or their local Department of Human Services office. Categories with the most room for re-qualification after a termination include pregnant women (up to 250% FPL, and coverage continues through 12 months postpartum under federal rules), children under 19 through TennCare Kids (age-tiered income limits), disabled adults meeting SSI criteria, and parents with minor children in households at or below 100% FPL. For everyone else, the ACA Marketplace is the primary path. The 2026 ACA Marketplace OEP for 2027 coverage runs November 1, 2026 through January 15, 2027, making the 90-day SEP after TennCare loss the only available enrollment window for most people losing coverage mid-year.
TennCare Income Limits and Eligibility Categories for 2026
TennCare uses Modified Adjusted Gross Income (MAGI) for most eligibility determinations in 2026. Tennessee's eligibility rules create four distinct groups. Parents and caretaker relatives with dependent children qualify up to approximately 100% of the Federal Poverty Level, which is about $21,640 per year for a household of two in 2026. Pregnant women qualify up to 250% FPL, approximately $54,100 for a household of two, and coverage continues through 12 months postpartum under the American Rescue Plan Act provision now made permanent. Children under 19 qualify through TennCare Kids, with income limits that vary by age. Adults on SSI or receiving Social Security Disability Insurance who qualify for Medicare may receive both Medicare and TennCare as dual-eligible beneficiaries. Non-disabled adults without dependent children do not qualify for TennCare under any income level, unlike Medicaid expansion states where adults qualify up to 138% FPL.
TennCare Eligibility Income Limits by Category, Tennessee 2026| Eligibility category | Income limit (approx. % FPL) | Annual income limit (2026) |
|---|
| Children under 19 (TennCare Kids) | 133-195% FPL (varies by age) | Varies by age and household size |
| Pregnant women | 250% FPL | $54,100 (household of 2) |
| Parents/caretaker relatives | ~100% FPL | $21,640 (household of 2) |
| SSI recipients / Disabled adults | Federal SSI criteria | SSI income rules apply |
| Non-disabled adults without children | Not eligible | No income limit: categorically excluded |
Tennessee has not expanded Medicaid under the ACA. These limits reflect TennCare's categorical eligibility rules as of 2026 per tenncare.tn.gov. Pregnant women coverage extends 12 months postpartum. TennCare Kids income limits vary by child's age (195% FPL under age 1, 142% FPL ages 1-6, 133% FPL ages 6-19). FPL values based on 2026 HHS Poverty Guidelines.

ACA Marketplace Coverage After Losing TennCare in Tennessee 2026
Losing TennCare qualifies as a qualifying life event that triggers a 90-day Special Enrollment Period for ACA Marketplace plans at healthcare.gov. Tennessee uses the federal Marketplace, not a state-based exchange, so all TennCare-to-Marketplace transitions go through healthcare.gov. The 2026 subsidy structure matters significantly for people who lose TennCare: enhanced premium tax credits from the American Rescue Plan Act expired January 1, 2026, returning the 400% FPL subsidy cliff. People with incomes between 100% and 400% FPL ($15,960 to $63,840 single person in 2026) still qualify for standard ACA premium tax credits under the Affordable Care Act. People above 400% FPL receive no subsidy in 2026 and pay full premium, which averages $500 to $800 per month for a 40-year-old in Tennessee.
Silver plans on the Tennessee Marketplace deserve special attention for people transitioning from TennCare in 2026. Tennesseans with incomes between 100% and 250% FPL (up to approximately $39,900 single, $82,500 family of four in 2026) qualify for cost-sharing reductions on Silver plans, which can dramatically reduce the deductible from the standard $3,000 to as low as $150, and reduce the out-of-pocket maximum from $10,600 to under $3,000. The 1095-A tax form, which Marketplace enrollees receive each January, is used to reconcile premium tax credits on your federal tax return. Enroll at healthcare.gov during your 90-day SEP, select your plan, pay your first premium, and upload your TennCare termination letter as proof of the qualifying event.
Documents Needed to Enroll in the Marketplace After Losing TennCare
Three sets of documents drive the TennCare-to-Marketplace application. First, your TennCare termination letter: this is your proof of the qualifying life event (loss of coverage) that opens the 90-day SEP window. Upload it to healthcare.gov within 30 days of selecting a plan. Second, proof of 2026 income: healthcare.gov uses projected annual Modified Adjusted Gross Income for the current year, not last year's income. Recent pay stubs, an employer letter, or a self-employed income estimate covering the rest of 2026 work well. Third, Social Security numbers for everyone applying. TennCare loss-to-Marketplace transitions do not require Section 9831 HIPAA creditable coverage certificates because Medicaid loss itself is the qualifying event under 45 CFR 155.420. Current Tennessee address and ZIP code are required because plan availability and premiums differ by county.
Frequently Asked Questions
How long do I have to enroll in an ACA Marketplace plan after losing TennCare?
You have 90 days from the date your TennCare coverage ended to enroll in an ACA Marketplace plan through the Loss of Minimum Essential Coverage Special Enrollment Period. This is longer than the standard 60-day SEP that applies to most other qualifying life events. Log in to healthcare.gov, select 'I lost qualifying health coverage,' choose Medicaid or CHIP as the type of coverage lost, and enter your TennCare termination date. Your 90-day clock starts from that termination date, not from when you received the notice.
Why is TennCare in Tennessee different from Medicaid in other states?
Tennessee is one of 10 states that has not expanded Medicaid under the ACA as of 2026. In 40 expansion states plus DC, adults qualify for Medicaid up to 138% FPL, which is $22,025 for a single person in 2026. TennCare covers a much narrower group: parents and caretakers up to approximately 100% FPL, pregnant women up to 250% FPL, children under 19 through TennCare Kids with age-tiered income limits, and disabled adults. Non-disabled adults without children do not qualify for TennCare at any income level. This means losing TennCare in Tennessee carries different risks than losing Medicaid in an expansion state.
Can I re-qualify for TennCare after losing it?
Possibly, depending on your category. Parents with dependent children can re-apply year-round if their income is at or below approximately 100% FPL ($21,640 for a household of two in 2026). Pregnant women can re-apply up to 250% FPL. Children under 19 can re-apply for TennCare Kids at any time, with income limits that vary by age. Non-disabled adults without dependent children are categorically excluded from TennCare. Apply through tenncare.tn.gov or your local Department of Human Services office. If your termination was based on a paperwork error or outdated income information, file an appeal within 30 days of the notice date.
What if my income is under 100% FPL and I cannot re-qualify for TennCare?
Tennessee adults with income under 100% FPL who do not meet TennCare categorical requirements fall into the Medicaid coverage gap. ACA Marketplace subsidies start at 100% FPL, so these individuals are not eligible for subsidized Marketplace coverage either. Options include: emergency Medicaid for qualifying medical emergencies, community health centers that provide sliding-scale care regardless of insurance (find locations at findahealthcenter.hrsa.gov), and assistance from legal aid organizations like the Tennessee Justice Center at (615) 255-0331 who may help identify overlooked eligibility.
What is the TennCare appeal process and how long do I have?
Tennessee allows 30 days from the date of the termination notice to request a TennCare fair hearing. Call TennCare Member Services at 1-800-342-3145 or submit a written request to the Tennessee Division of TennCare. If you request the hearing before your coverage end date, you may receive continuation of benefits during the appeal process. Appeals based on procedural errors (state did not process documents you submitted on time) or disputed income calculations have the best success rates. A free legal aid attorney from Tennessee Justice Center or Legal Aid Society of Middle Tennessee can help with the appeal at no cost.
Do my children lose TennCare if I do?
Not necessarily. TennCare Kids eligibility for children under 19 is evaluated separately from adult TennCare eligibility and uses age-tiered income limits (195% FPL for infants under 1, 142% FPL for ages 1-6, 133% FPL for ages 6-19 per tenncare.tn.gov). Even if you as an adult no longer qualify for TennCare, your children may still be eligible. Apply for TennCare Kids through tenncare.tn.gov or your local Department of Human Services office year-round. Enrollment is not tied to the adult enrollment timeline and has no deadline.
Does the 2026 ACA subsidy cliff affect me if I am switching from TennCare to the Marketplace?
Yes, if your income is above 400% FPL ($63,840 for a single person, $132,000 for a family of four in 2026). The enhanced premium tax credits from the American Rescue Plan Act expired January 1, 2026, so people above 400% FPL receive no ACA premium tax credit and pay full premium, typically $500 to $900 per month for a 40-year-old in Tennessee. If your income is between 100% and 400% FPL, standard ACA premium tax credits still apply and Silver plans remain affordable, especially with cost-sharing reductions for incomes under 250% FPL.
What documents do I need to prove I lost TennCare when applying at healthcare.gov?
Your TennCare termination letter or written notice from the Tennessee Division of TennCare is the primary proof of qualifying life event. Upload it to healthcare.gov within 30 days of selecting a plan. You will also need Social Security numbers for all applicants, your current Tennessee ZIP code, and proof of projected 2026 household income (recent pay stubs or a letter from your employer). For TennCare Kids applications, birth certificates for children are required. Free navigator assistance is available at localhelp.healthcare.gov if you need help assembling documents.
