Moving to Tennessee is a qualifying life event that triggers a 60-day SEP for ACA Marketplace enrollment. The SEP clock starts the day you establish residency in Tennessee, not the day you sell your old home or sign a new lease. Two important Tennessee-specific facts shape your options: first, Tennessee is one of the 10 states that has not expanded Medicaid under the ACA as of 2026, meaning TennCare has strict eligibility rules that exclude most low-to-moderate-income adults who are not pregnant, disabled, or children. Second, Tennessee does not operate a state-based exchange, so every new resident enrolls through the federal Marketplace at healthcare.gov. The move SEP requires that you had qualifying health coverage immediately before the move or that you are newly gaining access to plans in a new service area. If you were uninsured before moving to Tennessee, you may not qualify for the move-based SEP, but you could still qualify during ACA Open Enrollment in November 2026.
Tennessee's non-expansion status creates a coverage gap for adults with incomes below 100% FPL who do not qualify for TennCare. Federal Marketplace subsidies start at 100% FPL, so adults below that threshold fall into a gap where they are too poor for Marketplace subsidies but do not qualify for TennCare unless they meet the narrow categorical requirements. For most Tennessee movers, the decision is a three-way choice: (1) a subsidized ACA Marketplace plan through healthcare.gov for those with income between 100% and 400% FPL in 2026, (2) TennCare if you meet the categorical and income requirements, or (3) COBRA continuation from your previous employer if you left a job. This guide covers all three paths, the 60-day window, the documents required to trigger the move SEP, and what happens if you miss the deadline.
7 Steps to Get Coverage
Common Mistakes That Cost People Thousands
The most costly mistakes Tennessee movers make when switching health insurance:
- Assuming your old state Medicaid transfers to Tennessee. Medicaid does not transfer between states. You must apply for TennCare separately, and most adults in Tennessee do not qualify given the state's non-expansion status.
- Missing the 60-day SEP window by treating the move date as the day you signed a lease rather than the day you actually established residency. Healthcare.gov asks for the move date you can document with a utility bill or lease.
- Enrolling in COBRA without comparing subsidized Marketplace plans first. Most people moving to Tennessee qualify for significant premium tax credits that make a Silver Marketplace plan far cheaper than COBRA.
- Using last year's income to estimate 2026 subsidies. ACA subsidies are based on projected current-year household income. A recent job change means you should use only projected 2026 earnings going forward.
- Forgetting to check CoverKids CHIP for children. Tennessee's CoverKids CHIP program covers children up to 250% FPL year-round at little or no cost, even if parents do not qualify for TennCare.
- Not updating your address in healthcare.gov before the 60-day SEP expires. Your old state plan may stop covering Tennessee providers. Enroll in a Tennessee plan and cancel the prior-state plan to avoid paying two premiums.
TennCare vs ACA Marketplace vs COBRA: Choosing the Right Path in 2026
Tennessee movers face a three-way decision that turns almost entirely on household income. TennCare (Tennessee's Medicaid program) is free but narrow: as of 2026, Tennessee has not expanded Medicaid under the ACA, so TennCare covers pregnant women, children under 19 (through CoverKids), aged adults (65+) qualifying for SSI, and disabled adults meeting strict federal SSI criteria. Working-age adults without disabilities and without dependent children typically cannot get TennCare in 2026, regardless of how low their income is. The ACA Marketplace fills that gap for adults with incomes at or above 100% FPL, which is $15,960 for a single person in 2026. Premium tax credits reduce monthly costs substantially: at 200% FPL ($31,920 for a single person), a benchmark Silver plan costs roughly $67 per month after the premium tax credit per KFF's 2026 Marketplace Subsidy Calculator. COBRA preserves your prior plan but at 102% of the full premium, typically $600 to $1,800 per month for an individual.
Adults with income below 100% FPL who do not meet TennCare's categorical requirements fall into Tennessee's coverage gap. Federal Marketplace subsidies (premium tax credits) begin at 100% FPL, so adults earning below that threshold receive no subsidy and face full unsubsidized Marketplace premiums, which typically run $400 to $700 per month for a single adult in 2026. The coverage gap affects an estimated 100,000+ Tennessee adults as of 2026. Short-term health plans are available in Tennessee without the ACA's essential health benefit requirements, but they lack prescription coverage, mental health parity, and no preexisting condition protections. Short-term plans do not qualify as minimum essential coverage and do not satisfy the qualifying life event prior-coverage requirement for a future move-based SEP. The decision matrix is: TennCare first (free, if categorical requirements met); ACA Marketplace with subsidies second (for income 100% to 400% FPL); COBRA only if network continuity is critical.
Documents Needed to Trigger the Tennessee Move SEP
Healthcare.gov requires documentation that you actually moved to Tennessee and that you had qualifying health coverage immediately before the move (or meet the new-access exception). Tennessee residency documentation accepted includes a signed Tennessee lease or mortgage closing statement, a Tennessee utility bill (gas, electric, water) dated within 30 days of your move date, a Tennessee car registration or driver's license, or a letter from a Tennessee employer confirming your start date. The prior coverage requirement means healthcare.gov will also ask for a HIPAA certificate of creditable coverage, a prior plan ID card dated before the move, or an employer letter confirming you had coverage on the last day of work. Submitting both sets of documents at the time of application prevents delays. If you are moving from a state Medicaid program, the Medicaid termination letter serves as proof of prior coverage and may also trigger a separate 90-day loss-of-Medicaid SEP in Tennessee.
TennCare Income Limits and CoverKids CHIP Thresholds in 2026
TennCare income and eligibility rules in 2026 depend on your category. Pregnant women qualify at incomes up to 195% FPL (appróximately $31,122 for a household of 1, $42,639 for a household of 2 when adding the unborn child). Children under 19 qualify for CoverKids CHIP at incomes up to 250% FPL (appróximately $40,050 for a single-child household in 2026). Aged and disabled adults qualifying for SSI receive TennCare automatically alongside their SSI determination. All other working-age adults without a qualifying categorical factor, including most adults who recently moved to Tennessee, do not qualify for TennCare in 2026. ACA Marketplace subsidies fill the gap for those with incomes between 100% FPL and 400% FPL. The 400% FPL ACA subsidy cliff returned for 2026 after the enhanced premium tax credits from the American Rescue Plan Act expired on January 1, 2026, so adults earning above 400% FPL pay full unsubsidized premiums in Tennessee.

TennCare (Tennessee Medicaid) does not cover working-age adults without categorical eligibility (pregnancy, disability, SSI status, or foster care). Adults below 100% FPL who do not qualify for TennCare face Tennessee's coverage gap. The 400% FPL subsidy cliff is back for 2026.

What Happens If You Miss the 60-Day Tennessee Move SEP
Missing the 60-day move-based SEP means your next opportunity to enroll in an ACA Marketplace plan in Tennessee is the next Open Enrollment Period, which opens November 1, 2026 for 2027 coverage. Between the SEP expiration and November 1, 2026, you have no subsidized Marketplace option unless another qualifying life event occurs, such as losing COBRA coverage, getting married, having a child, or experiencing a loss of income that makes you eligible for TennCare. TennCare enrollment is year-round for those who qualify categorically, so if you are pregnant, a child under 19, or meet SSI criteria, you can apply at any time. COBRA remains available for the 60-day election period from when your prior employer coverage ended, separate from the move-based SEP window. The most common mistake is assuming that moving automatically extends your COBRA election window; COBRA and the Marketplace SEP run concurrently, not sequentially.
Frequently Asked Questions
How long do I have to get health insurance after moving to Tennessee?
Moving to Tennessee triggers a 60-day Special Enrollment Period (SEP) to enroll in an ACA Marketplace plan through healthcare.gov. The 60-day clock starts on the day you establish Tennessee residency. For example, if you move on June 13, 2026, your SEP window runs through August 11, 2026. Miss that deadline and you must wait until the next ACA Open Enrollment Period starting November 1, 2026. TennCare and CoverKids CHIP are available year-round for those who qualify categorically. You must have had qualifying health coverage immediately before the move to use the move-based SEP.
Does Tennessee have Medicaid expansion? Will I qualify for TennCare after moving?
No. Tennessee is one of the 10 states that has not expanded Medicaid under the ACA as of 2026. TennCare covers pregnant women (up to 195% FPL), children under 19 through CoverKids CHIP (up to 250% FPL), and SSI-eligible aged or disabled adults. Most working-age adults who move to Tennessee without a pregnancy, disability, or dependent children will not qualify for TennCare, regardless of income level. Adults earning below 100% FPL who do not qualify for TennCare fall into Tennessee's coverage gap: too poor for subsidized Marketplace plans, but not eligible for TennCare.
What documents do I need to prove I moved to Tennessee for the SEP?
Healthcare.gov requires two types of documentation for the move-based SEP: proof of Tennessee residency and proof you had qualifying coverage before the move. Tennessee residency proof includes a signed lease or mortgage statement, a utility bill dated within 30 days, or a Tennessee driver's license. Prior coverage proof includes a HIPAA certificate of creditable coverage, a prior plan ID card, or an employer letter confirming coverage dates. Submit both documents when you apply to avoid delays. If you moved from a state Medicaid program, your Medicaid termination letter counts as prior coverage proof.
What is CoverKids and does my child qualify after moving to Tennessee?
CoverKids is Tennessee's CHIP (Children's Health Insurance Program) for uninsured children under 19 and pregnant women. Income limits are up to 250% FPL, which equals roughly $39,900 for a single-child household or $82,500 for a family of 4 in 2026. CoverKids enrollment is year-round with no waiting period. Coverage includes doctor visits, prescriptions, dental, and vision. Premiums range from $0 to $35 per child per month. Apply through InsureKidsNow.gov or healthcare.gov. Even if you do not qualify for TennCare yourself, your children may qualify for CoverKids.
Can I keep my old state's Medicaid after moving to Tennessee?
No. Medicaid eligibility is state-specific and does not transfer between states. When you establish Tennessee residency, your prior state's Medicaid coverage ends. You must apply separately for TennCare through the Tennessee Department of Human Services. If your prior state Medicaid is terminated due to the move, that termination letter serves as proof of prior qualifying coverage for the 60-day loss-of-Medicaid SEP, which gives you 90 days to enroll in a Tennessee Marketplace plan. The move-based SEP and the loss-of-Medicaid SEP can overlap, giving you up to 90 days in some cases.
Is COBRA worth it after moving to Tennessee?
Rarely. COBRA continues your prior employer plan at 102% of the full premium, which typically runs $600 to $1,800 per month for an individual and $1,400 to $2,800 per month for a family in 2026. Most people who moved to Tennessee and qualify for ACA subsidies will find a subsidized Silver Marketplace plan significantly cheaper. COBRA makes sense only if you have ongoing treatment with a specific specialist not in any Tennessee Marketplace network, or if you have already met a large deductible for 2026 and want to maintain that for the rest of the year. The COBRA election window is 60 days from when prior employer coverage ended.
What if I was uninsured before moving to Tennessee? Can I still get coverage?
The move-based 60-day SEP requires that you had qualifying health coverage immediately before the move. If you were uninsured, you may not qualify for the move SEP at healthcare.gov. Your main options are: (1) TennCare if you qualify categorically (pregnancy, disability, child under 19); (2) CoverKids CHIP for children; or (3) wait for ACA Open Enrollment starting November 1, 2026. If you are below 100% FPL and do not qualify for TennCare, you fall into Tennessee's coverage gap. Some Tennessee counties have community health centers offering sliding-scale care regardless of insurance status.
How do I enroll in a Tennessee health plan through healthcare.gov?
Go to healthcare.gov and log into your existing account or create a new one. Select 'Report a life change' and choose 'I moved to a new state or area.' Enter your Tennessee ZIP code and move date. Healthcare.gov will screen you for TennCare and CoverKids eligibility first. If you do not qualify for TennCare, you will see available Tennessee Marketplace plans sorted by premium. Use your projected 2026 household income (not last year's income) to calculate your premium tax credit. Compare Silver, Bronze, and Gold plans by premium, deductible, and network before enrolling. Your 1095-A form for 2026 will arrive in January 2027 for tax reconciliation.
