What Is Medical Expense Splitting?

Medical expense splitting is a method used by divorced or separated parents to divide their children's healthcare costs fairly. Each parent contributes to medical expenses in proportion to their income and custody time. This approach ensures that the financial burden of healthcare is shared equitably based on each parent's ability to pay.

Medical expense splitting typically covers health insurance premiums, deductibles, copayments, prescription costs, dental and vision care, orthodontia, therapy, and other uninsured medical costs. Courts often require parents to share these expenses in proportion to their incomes, with custody time adjustments for day-to-day medical costs incurred during parenting time.

Medical Expense Split Formula

Total Medical Costs = Insurance Premium + Deductible + Out-of-Pocket Max + Uninsured Costs

Income Ratio = Parent Income / Combined Income

Expense Share = Total Medical Costs × Income Ratio

Custody-Adjusted Share = Expense Share × (Custody % / Total Custody)
