Uncovered medical expenses are costs for a child's medical, dental, vision, orthodontic, therapy, prescription, or other health-related needs that are not paid by insurance. The Arizona Child Support Guidelines provide for sharing these expenses between the parents in proportion to their incomes.

The decree should specify what counts as an uncovered medical expense, what notice the paying parent must receive, how reimbursement requests are made, and what the deadline is for submission and payment. There are very specific details and timing for how to document, request and pay these expenses.

Ordinary uncovered medical expenses below a certain threshold are sometimes absorbed by each parent during their own parenting time.
