Michigan Child Support and Uninsured Medical Bills Explained

When a child needs braces, surgery, or other treatment, the bill can quickly become a fight between parents. In Michigan, the answer usually starts with the child support order—not with who is angrier, who paid first, or who thinks the expense was unnecessary.

Medical Expenses Are Part of Child Support

Michigan child support is not limited to the weekly or monthly base support number. Under MCSF 3.01, a monthly child support payment has multiple parts: base support under §3.02, adjusted for parenting time under §3.03; medical support obligations under §3.04 and health-care coverage and premium allocation under §3.05; and child-care expense obligations under §3.06.

That matters because medical reimbursement is usually not a separate side issue. Braces, surgery, counseling, prescriptions, co-pays, deductibles, and other uninsured medical bills may fall under the medical support portion of the child support order. The first place to look is the actual Uniform Child Support Order, not a text message argument between parents.

Ordinary Medical Expenses Come First

Each Uniform Child Support Order should identify an annual ordinary medical amount. That is the amount the support recipient must pay first before the parents divide additional uninsured medical expenses.

he reason is practical: ordinary medical support is already built into the support order. In other words, part of the support calculation assumes routine out-of-pocket medical costs will happen. For child support orders entered after January 1, 2025, using the 2025 Michigan Child Support Formula, MCSF-S 2.02(A) identifies the ordinary medical amount as $200 for one child, $400 for two children, and so on.

Do not assume the same number applies in every case. Older orders may use a different ordinary medical amount. The order controls.

Braces, Surgery, and Uninsured Medical Bills

Parents often frame this issue as “forcing parent to pay for braces” or “forcing parent to pay for surgery.” The better legal question is whether the expense is covered by the existing child support order and whether the requesting parent followed the reimbursement rules.

MCSF 3.04(A)(1) defines “medical” broadly. It includes treatments, services, equipment, medicines, preventative care, and similar goods or services associated with oral, visual, psychological, medical, and other related care, when provided or prescribed by health-care professionals for the children.

That definition matters for orthodontic treatment. Braces are oral care. A parent who refuses to contribute simply because the bill is expensive may have a problem if the order requires contribution to additional uninsured medical expenses and the procedural steps were followed.

The same concept can apply to surgery or other treatment, but the details matter. Insurance payments, denials, documentation, timing, and the language of the support order all matter.

Reimbursement Has Deadlines

Medical reimbursement is not automatic. MCL 552.511a(1) sets out requirements for a complaint seeking enforcement of a health-care expense.

The parent seeking reimbursement must show that the other parent is obligated to pay the child’s uninsured health-care expenses. A demand for payment of the uninsured portion must be made within 28 days after the insurer’s final payment or denial of coverage. Then, the other parent must fail to pay within 28 days after that demand.

Timing also matters when filing with the Friend of the Court. Under MCL 552.511a(1), the complaint must be submitted within the applicable statutory deadline, including one year after the expense was incurred, or six months after the insurer’s final payment or denial when the required insurance-claim steps were completed within two months after the expense was incurred. The statute also addresses default under a written agreement signed by both parents.

The practical point is simple: waiting can destroy an otherwise valid reimbursement claim.

Documentation Is Not Optional

he requesting parent should keep the bill, proof of payment, insurance explanation of benefits, denial documents, and the written demand sent to the other parent. The request should identify the child, the provider, the date of service, the amount charged, the amount insurance paid or denied, the uninsured balance, and the percentage or amount requested from the other parent.

SCAO forms FOC 13 and FOC 13a may provide organized ways to present the request and complaint. The form is not a substitute for evidence. The parent seeking payment still needs records.

Parenting Time, Child Support Review, and Medical Costs

Parenting time can affect child support because MCSF 3.01 and §3.03 recognize parenting-time adjustments in the base support calculation. Medical expenses are addressed separately under §3.04. That means a child support review may be appropriate when the broader order no longer matches the facts, but a reimbursement dispute is usually about enforcing the current order.

A parent should not confuse these issues. If the complaint is “the order is outdated,” that may call for a child support review. If the complaint is “the other parent did not pay their share of uninsured medical bills,” that may call for reimbursement enforcement.

Joint Legal Custody Can Complicate the Issue

Joint legal custody can create a separate dispute. One parent may argue, “I was not included in the decision, so I should not have to pay.” That argument may matter for custody or legal decision-making, but it does not automatically defeat medical reimbursement.

The safer approach is to communicate in writing before major treatment when possible. If parents with joint legal custody disagree about braces, surgery, or another significant medical decision, it may be necessary to ask the court to resolve the legal custody dispute before acting unilaterally.

That said, once the expense exists, the court may focus on the existing support order, MCSF 3.04(A), and whether the reimbursement process was followed.

What to do next

• Read the medical expense section of your Uniform Child Support Order.
• Identify the annual ordinary medical amount before demanding reimbursement.
• Keep bills, receipts, insurance documents, and written payment requests.
• Send reimbursement demands promptly and in writing.
• Consider a child support review if the overall order no longer fits the facts.
• Speak with a Michigan family law attorney before ignoring or refusing a medical reimbursement request.
