Tennessee law mandates that every child support order include provisions for health insurance coverage when available at reasonable cost. Under Tenn. Code Ann. § 36-5-101(h), courts must order one or both parents to provide health insurance if the premium cost does not exceed 5% of the providing parent's gross income. This requirement applies to all divorce, separation, and paternity cases involving minor children. The Tennessee Child Support Guidelines, codified in Rule 1240-02-04, establish how health insurance costs are calculated and divided between parents using the Income Shares model.

What Does Medical Support Mean in Tennessee Child Support Orders
Tennessee courts define medical support as three distinct components: health insurance premiums, uninsured medical expenses, and cash medical support. Under Tenn. Comp. R. & Regs. 1240-02-04-.04, the parent ordered to provide insurance must maintain coverage that includes medical, dental, and vision benefits when available at reasonable cost. The 5% affordability threshold means a parent earning $60,000 annually would be required to provide coverage only if premiums cost $3,000 or less per year ($250 per month). If employer-sponsored insurance exceeds this threshold, the court may order parents to obtain marketplace coverage or enroll the child in TennCare, Tennessee's Medicaid program.
Medical support extends beyond insurance premiums to include all uninsured medical expenses. These out-of-pocket costs encompass co-payments, deductibles, orthodontia, dental treatment, asthma medications, physical therapy, vision care, mental health counseling, and treatment for any acute or chronic medical condition. Tennessee's Income Shares model calculates each parent's share of these expenses proportionally based on their percentage of combined adjusted gross income.
How Tennessee Calculates Health Insurance Costs in Child Support
Tennessee uses the Income Shares model, which bases child support on the combined gross income of both parents. Under Tenn. Code Ann. § 36-5-101, the court first determines each parent's adjusted gross income, combines these figures, and consults the Child Support Schedule to establish the Basic Child Support Obligation (BCSO). Health insurance premiums are then added as an additional expense, separate from the BCSO, and divided proportionally between parents.
The calculation follows a specific formula established in Rule 1240-02-04-.04. First, the court identifies the actual monthly cost of the child's health insurance premium, including medical, dental, and vision coverage. This amount is added to the BCSO to create the Adjusted Support Obligation (ASO). Each parent's share equals their percentage of combined income. For example, if one parent earns $50,000 and the other earns $30,000, their combined income is $80,000. The first parent's income percentage is 62.5% ($50,000 ÷ $80,000), and the second parent's percentage is 37.5%. These percentages determine how the insurance cost is divided.
Example Health Insurance Calculation
| Income Component | Parent A | Parent B |
|---|---|---|
| Gross Monthly Income | $4,167 | $2,500 |
| Income Percentage | 62.5% | 37.5% |
| Basic Child Support (1 child) | $836 | $501 |
| Child's Health Insurance Premium | — | $350/month |
| Insurance Credit to Parent B | — | ($350) |
| Parent A's Share of Insurance | $219 | — |
| Parent B's Share of Insurance | — | $131 |
In this example, Parent B provides the health insurance at $350 per month. Parent A owes 62.5% of that cost ($219), which is added to their support obligation. Parent B receives credit for paying the full premium and is only responsible for their 37.5% share ($131).
The 5% Affordability Rule for Health Insurance Child Support Tennessee
Tennessee establishes a clear affordability standard for health insurance obligations in child support orders. Under Tenn. Comp. R. & Regs. 1240-02-04-.02, health insurance is considered reasonable if the premium does not exceed 5% of the providing parent's gross income. This threshold applies specifically to the cost of adding the child to an existing policy, not the total family premium.
The 5% cap serves as protection against excessive financial burden on the providing parent. A parent with gross annual income of $40,000 would have a maximum insurance obligation of $2,000 per year ($167 per month). If the employer-sponsored health insurance premium for adding a child exceeds this amount, the court may explore alternatives such as the other parent's employer coverage, marketplace insurance, or TennCare enrollment.
When dental and vision coverage would push the total premium above 5% of gross income, Tennessee law requires only medical insurance. The court cannot mandate vision or dental coverage if adding these benefits exceeds the affordability threshold. However, if both medical and dental/vision coverage combined remain under 5%, all coverage types must be included in the support order.
Uninsured Medical Expenses Division in Tennessee
Tennessee child support orders address uninsured medical expenses through a two-tier system. Under Tenn. Comp. R. & Regs. 1240-02-04-.04, the custodial parent typically pays the first $250 per year per child in uninsured medical expenses before the proportional sharing requirement applies. This threshold covers routine co-payments, standard prescription costs, and minor medical expenses.
Once uninsured expenses exceed $250 per child annually, both parents share the remaining costs according to their income percentages. If Parent A earns 65% of combined income and Parent B earns 35%, they split all uninsured expenses above the threshold in that same ratio. This applies to non-covered services including:
- Health insurance co-payments and deductibles
- Orthodontic treatment costs
- Mental health counseling and therapy sessions
- Vision care including eyeglasses and contacts
- Physical therapy and rehabilitation services
- Prescription medications not covered by insurance
- Emergency room co-payments
- Specialist visit fees
Tennessee distinguishes between recurring and non-recurring uninsured expenses. Predictable, ongoing costs such as monthly allergy medication or weekly therapy sessions are calculated and added to the monthly child support amount. Non-recurring expenses, such as unexpected emergency room visits or one-time orthodontic payments, are allocated between parents as they occur based on income percentages.
National Medical Support Notice (NMSN) in Tennessee
When a parent fails to enroll a child in available employer-sponsored health insurance, Tennessee courts use the National Medical Support Notice to enforce compliance. Under federal regulations at 42 U.S.C. § 651 and Tennessee's Title IV-D enforcement provisions in Tenn. Code Ann. § 36-5-501, the child support agency can issue an NMSN directly to the obligated parent's employer.
The NMSN operates as a two-part legal document. Part A goes to the employer, requiring them to confirm whether the employee has health insurance available and whether dependent coverage is offered. The employer must respond within 20 business days. Part B goes to the plan administrator, instructing them to enroll the child in available coverage. The employer must begin coverage within 10 days after the NMSN becomes effective.
Employers face significant consequences for failing to comply with a National Medical Support Notice. Under Tennessee law, an employer who willfully refuses to enroll a child becomes liable for any medical costs that insurance would have covered. Courts may also hold non-compliant employers in contempt, subjecting them to fines and penalties. The enrollment occurs regardless of the employee's cooperation—employers must enroll children in coverage even if the obligated parent refuses to complete enrollment paperwork.
When TennCare Covers Children in Divorce Cases
TennCare, Tennessee's Medicaid program, provides an alternative when private health insurance is unavailable or unaffordable. Children under age 19 with family income at or below 211% of the Federal Poverty Level may qualify for TennCare coverage. For 2026, this income threshold is approximately $55,000 annually for a family of three.
Tennessee courts may order TennCare enrollment when neither parent has affordable employer-sponsored insurance, marketplace premiums exceed 5% of both parents' income, or the child has special medical needs that TennCare covers more comprehensively. Under Tenn. Code Ann. § 36-5-101(h), the court retains authority to order parents to apply for TennCare when private insurance options do not meet the child's healthcare needs.
When a child receives TennCare benefits, Tennessee may seek reimbursement from the non-custodial parent through the child support system. The state can include cash medical support payments in the support order, requiring the obligated parent to contribute toward the child's healthcare costs even though TennCare provides coverage. This cash medical support helps offset the state's expenditure on the child's medical care.
Modifying Child Support Orders for Health Insurance Changes in Tennessee
Tennessee allows modification of child support orders when health insurance circumstances change substantially. Under Tenn. Comp. R. & Regs. 1240-02-04-.05, a parent may petition for modification based on a significant variance of 15% or more between the current order and the amount calculated under current guidelines. However, healthcare needs provide an explicit exception: the court may modify support based solely on the necessity of providing for the child's healthcare, regardless of whether the variance reaches 15%.
Changes that typically warrant modification include loss of employer-sponsored health insurance, significant premium increases exceeding the 5% affordability threshold, a child developing chronic health conditions requiring additional coverage, one parent gaining access to more affordable insurance options, or changes in a child's special healthcare needs.
The modification process requires filing a Petition to Modify with the court that issued the original order. Tennessee courts process modification requests within 90-120 days in most cases, though contested modifications may require hearings and take longer. Both parents must submit updated financial information, including current income documentation and health insurance cost verification.
Modification Timeline and Requirements
| Step | Timeframe | Requirements |
|---|---|---|
| File Petition | Day 1 | Current income docs, insurance quotes |
| Service on Other Parent | 30 days | Formal service required |
| Response Period | 30 days after service | Other parent may contest |
| Mediation (if contested) | 30-60 days | Required before hearing |
| Court Hearing | 30-90 days | If parties cannot agree |
| Order Entry | 7-14 days after hearing | Effective date specified |
Enforcement of Health Insurance Child Support Orders in Tennessee
Tennessee provides multiple enforcement mechanisms when a parent fails to maintain court-ordered health insurance. The Tennessee Department of Human Services Child Support Services division can intercept tax refunds, suspend driver's licenses, report to credit bureaus, and pursue contempt of court charges against non-compliant parents.
Wage withholding serves as the primary enforcement tool. Under Tenn. Code Ann. § 36-5-101, Tennessee caps wage withholding at 50% of disposable income after deducting FICA taxes, federal withholding, and the child's health insurance premium. This limit ensures obligated parents retain sufficient income for basic living expenses while meeting their support obligations.
When a parent loses health insurance coverage and fails to notify the court or obtain replacement coverage, the other parent may file a motion for contempt. Courts may order the non-compliant parent to pay all medical expenses incurred during the coverage gap, reimburse the other parent for obtaining alternative coverage, pay attorney's fees associated with enforcement, and face potential jail time for willful violation of court orders.
Tennessee Divorce Filing Fees and Court Costs 2026
Tennessee divorce filing fees vary by county and case type. As of January 2026, the statutory base fee is $125 for cases without minor children and $200 for cases with minor children under Tenn. Code Ann. § 8-21-401. However, additional county litigation taxes and service fees increase actual costs.
Filing Fees by Major County (January 2026)
| County | Without Children | With Children |
|---|---|---|
| Davidson (Nashville) | $184.50-$226.50 | $259.50-$301.50 |
| Shelby (Memphis) | $306.50 | $381.50 |
| Knox (Knoxville) | $195-$240 | $270-$315 |
| Hamilton (Chattanooga) | $190-$235 | $265-$310 |
Individuals unable to afford filing fees may request a fee waiver by submitting the Uniform Civil Affidavit of Indigency under Tennessee Supreme Court Rule 29. Applicants earning at or below 125% of the federal poverty level ($19,506 annually for a single person in 2026) are presumed eligible for fee waivers. Courts review waiver requests individually and may grant full or partial fee relief based on financial circumstances.
Frequently Asked Questions About Health Insurance Child Support Tennessee
Is health insurance required in Tennessee child support orders?
Yes, Tennessee law mandates health insurance provisions in all child support orders when coverage is available at reasonable cost. Under Tenn. Code Ann. § 36-5-101(h), courts must order one or both parents to provide health insurance if the premium costs 5% or less of the providing parent's gross income. Both Title IV-D cases enforced through child support services and private divorce cases require medical support provisions.
What happens if neither parent has affordable health insurance in Tennessee?
When neither parent has affordable employer-sponsored insurance, Tennessee courts may order parents to obtain marketplace coverage, apply for TennCare (if income-eligible), or include cash medical support in the child support order. Children under 19 with family income at or below 211% of the Federal Poverty Level (approximately $55,000 for a family of three in 2026) may qualify for TennCare coverage. The court retains discretion to order the most practical healthcare solution based on the parents' circumstances.
How are uninsured medical expenses divided in Tennessee?
The custodial parent typically pays the first $250 per year per child in uninsured medical expenses. Beyond this threshold, both parents share costs proportionally based on their income percentages. If Parent A earns 60% of combined income, they pay 60% of uninsured expenses above $250. Qualifying expenses include co-payments, deductibles, orthodontia, mental health counseling, vision care, and prescription medications not covered by insurance.
Can I modify child support if health insurance costs change significantly?
Yes, health insurance changes provide specific grounds for child support modification in Tennessee. Under Tenn. Comp. R. & Regs. 1240-02-04-.05, the necessity of providing for a child's healthcare needs justifies modification regardless of whether the standard 15% significant variance exists. Common qualifying changes include loss of employer coverage, premium increases exceeding 5% of income, or a child developing new healthcare needs.
What is the National Medical Support Notice and how does it work in Tennessee?
The National Medical Support Notice (NMSN) is a federal enforcement tool that orders employers to enroll children in available health insurance. Tennessee child support agencies issue NMSNs directly to employers when parents fail to maintain court-ordered coverage. Employers must respond within 20 business days and begin coverage within 10 days after the notice becomes effective. Employers who refuse to comply become liable for medical expenses the insurance would have covered.
How does Tennessee calculate the health insurance portion of child support?
Tennessee adds health insurance costs to the Basic Child Support Obligation as an additional expense. The actual monthly premium for the child's coverage is determined, then divided between parents based on their income percentages. If one parent pays the premium, they receive credit in the support calculation, while the other parent's share is added to their support obligation. The Income Shares model ensures costs are distributed proportionally to each parent's ability to pay.
What counts as reasonable cost for health insurance in Tennessee child support?
Tennessee defines reasonable cost as health insurance premiums not exceeding 5% of the providing parent's gross income. For a parent earning $50,000 annually, the maximum reasonable insurance cost would be $2,500 per year ($208 monthly). This calculation considers only the cost of adding the child to coverage, not the total family premium. If dental and vision coverage would push costs above 5%, only medical insurance is required.
Can my employer refuse to add my child to health insurance after divorce?
No, employers cannot refuse to enroll a child when a valid court order or National Medical Support Notice requires coverage. Under federal ERISA regulations and Tennessee law, employers must treat a qualified medical support order the same as an enrollment event. Employers who willfully refuse enrollment face liability for medical expenses and potential contempt of court charges. The child's enrollment occurs regardless of whether the employee cooperates with paperwork.
How long does Tennessee require parents to maintain health insurance for children?
Tennessee child support obligations, including health insurance requirements, generally continue until the child reaches age 18 or graduates from high school, whichever occurs later, but not beyond age 19. Courts may extend medical support obligations for children with disabilities or special needs. The divorce decree or child support order specifies the exact duration based on the child's circumstances and any agreements between parents.
What happens if my ex-spouse cancels the child's health insurance?
If a parent cancels court-ordered health insurance without obtaining replacement coverage, they may face contempt of court charges, liability for all medical expenses incurred during the coverage gap, and wage withholding for premium costs if the other parent obtains coverage. Tennessee enforcement options include tax refund interception, license suspension, and credit bureau reporting. Document the cancellation and file a motion for contempt promptly to protect your child's healthcare access.
