Child Support and Medical Expenses: Who Pays for Health Insurance in 2025?

Child Support and Medical Expenses: An Overview

Medical expenses are one of the most important and frequently disputed components of child support. Healthcare costs in the United States continue to rise, and ensuring that children have adequate medical coverage is a top priority for family courts in every state.

When a court establishes a child support order, it typically addresses three separate medical-related obligations: health insurance coverage, routine medical costs included in the base support amount, and extraordinary or unreimbursed medical expenses that must be shared separately.

Understanding how these three components work together is essential for both parents. The parent receiving support needs to know what medical costs are covered by the base amount and what can be requested separately. The parent paying support needs to understand their obligations for insurance premiums and out-of-pocket costs beyond the monthly payment.

This article provides a comprehensive guide to how medical expenses are handled in child support cases, including insurance requirements, cost-sharing formulas, and practical strategies for managing healthcare costs between two households.

Health Insurance Requirements in Child Support

Federal law requires that all child support orders include a provision for health insurance coverage for the child. Under the Affordable Care Act, children can remain on a parent's employer-sponsored health plan until age 26, and courts routinely order one or both parents to maintain coverage.

The general rules for health insurance in child support cases are as follows:

1. Priority to employer-sponsored coverage: If either parent has access to affordable employer-sponsored health insurance, the court will typically order that parent to enroll the child. "Affordable" generally means the cost does not exceed a certain percentage of the parent's income, though the specific threshold varies by state.
2. Cost is factored into support: The cost of the child's health insurance premium is usually factored into the child support calculation. In Income Shares states, the premium is added to the basic support obligation and allocated between the parents based on their income shares.
3. Both parents may be ordered to provide coverage: If both parents have access to employer plans, the court may order the parent with the better or more affordable coverage to provide primary insurance, with the other parent's plan serving as secondary coverage.
4. Private insurance alternatives: If neither parent has employer coverage, the court may order the parents to obtain private insurance through the ACA marketplace or other sources and share the cost proportionally.

If a parent is ordered to provide health insurance and fails to do so, the court can enforce the order through wage garnishment, contempt proceedings, or other enforcement mechanisms. The parent may also be held responsible for any medical costs the child incurred while uninsured.

Unreimbursed Medical Expenses: How They Work

Basic child support is intended to cover routine healthcare costs such as occasional doctor visits and standard medications. However, most child support orders also address unreimbursed medical expenses, which are the costs that insurance does not cover.

Common unreimbursed medical expenses include:

• Copayments: The fixed amount paid for each office visit, specialist visit, or prescription
• Deductibles: The annual amount the insured must pay before insurance begins covering costs
• Coinsurance: The percentage of costs the insured pays after meeting the deductible
• Prescription medications: Costs for drugs not fully covered by insurance
• Dental care: Cleanings, fillings, extractions, and orthodontic work
• Vision care: Eye exams, glasses, and contact lenses
• Mental health services: Therapy, counseling, and psychiatric care
• Physical, occupational, or speech therapy: Rehabilitative services not fully covered by insurance

Most child support orders specify that unreimbursed medical expenses above a certain threshold are to be shared between the parents proportionally. Some orders set a minimum amount that must be exceeded before sharing kicks in, while others require sharing of all unreimbursed amounts regardless of the size.

How Medical Expenses Are Divided Between Parents

The most common method for dividing medical expenses is proportional sharing based on each parent's share of the combined income. This is how it works in practice:

In this example, if the child has $2,000 in unreimbursed medical expenses during the year, Parent A would be responsible for $1,200 and Parent B would owe $800.

The process typically works as follows:

1. One parent pays the medical bill at the time of service.
2. That parent submits the claim to insurance and receives the explanation of benefits showing the unreimbursed amount.
3. The parent who paid sends a copy of the bill and the EOB to the other parent with a request for their proportional share.
4. The other parent reimburses their share within a specified time period, usually 30 days.

Most court orders specify the timeline for reimbursement and the documentation required. Failure to pay a share of medical expenses can be enforced the same way as failure to pay base child support.

Dental, Vision, and Mental Health Coverage

Health insurance plans often treat dental, vision, and mental health as separate categories with their own coverage limits and costs. Courts generally include these as part of the overall medical expense obligation.

Dental care: Routine cleanings and exams are usually considered part of the basic support obligation, but major dental work such as fillings, crowns, root canals, and orthodontics are treated as unreimbursed medical expenses. Orthodontics, particularly braces, is one of the most commonly disputed dental expenses in child support cases. Courts usually order both parents to share the cost unless one parent objects on the basis that the treatment is cosmetic rather than medically necessary.

Vision care: Eye exams, prescription glasses, and contact lenses are typically treated as shared medical expenses. The cost of vision insurance premiums, if purchased separately, may also be allocated between the parents.

Mental health: Therapy sessions, psychological evaluations, and psychiatric medications are treated as medical expenses. Courts are increasingly recognizing the importance of mental health care for children and are generally willing to order parents to share these costs. This includes individual therapy, family therapy, and in some cases, specialized treatment for conditions such as ADHD, anxiety, or depression.

Extraordinary Medical Expenses

Some medical situations involve costs far beyond routine care. Courts refer to these as extraordinary medical expenses and handle them through a separate sharing arrangement. Examples include:

• Emergency room visits and hospital stays
• Surgical procedures and post-operative care
• Ongoing treatment for chronic conditions such as diabetes, asthma, or cancer
• Specialized equipment such as wheelchairs, hearing aids, or prosthetics
• Home healthcare or nursing services
• Residential treatment programs for behavioral or substance abuse issues

Courts typically require both parents to share extraordinary medical expenses regardless of the basic support amount. In some states, extraordinary expenses can be grounds for modifying an existing child support order if the costs are substantial and ongoing.

Parents facing extraordinary medical expenses should notify the other parent and the court as soon as possible. Delaying communication about major medical costs can complicate the reimbursement process and create additional conflict.

State-by-State Differences

While the general principles are consistent across states, the specifics of how medical expenses are handled vary. Here are some notable differences:

Some states set a threshold amount that unreimbursed expenses must exceed before they are shared. For instance, a state might require that unreimbursed expenses exceed $250 per year per child before proportional sharing is triggered. Below that amount, the custodial parent is expected to absorb the cost as part of routine child-rearing expenses covered by the base support.

Other states require sharing of all unreimbursed amounts, no matter how small. Check your specific state's guidelines or consult with a family law attorney to understand the rules in your jurisdiction.

Practical Tips for Managing Medical Expenses

Disputes over medical expenses are among the most common sources of conflict between divorced or separated parents. The following practices can help reduce disagreements:

1. Keep detailed records: Save all medical bills, insurance explanations of benefits, receipts, and reimbursement requests. Maintain a dedicated folder or digital file for each child's medical expenses.
2. Communicate promptly: Send copies of medical bills to the other parent as soon as you receive them. Most court orders require notification within 30 days. Delayed requests for reimbursement are more likely to be disputed.
3. Agree on a process: If possible, establish a written agreement with the other parent about how medical expenses will be handled, including who will pay at the time of service, how reimbursement requests will be submitted, and the timeline for payment.
4. Use a shared expense tracking tool: Several apps and online tools are designed to help co-parents track and split expenses. Using one can reduce miscommunication and provide a clear record.
5. Get court approval for major expenses: Before committing to a major medical expense such as orthodontic treatment or elective surgery, discuss it with the other parent. If you cannot agree, seek court guidance before incurring the cost to avoid disputes about whether it was necessary.
6. Understand your insurance coverage: Know what your insurance plan covers and what it does not. Submit claims promptly and track the status. Unreimbursed amounts cannot be shared until the insurance company has processed the claim.
7. Do not withhold medical care: Even if the other parent refuses to pay their share, do not deny the child necessary medical treatment. Instead, proceed with the care and pursue reimbursement through the court if needed.
