Ordinary medical is copays, deductibles, medical supplies, and the like.
The child support formula presumes that each child incurs a fixed amount on medical expenses each year. 1 child = $345; 2 children = $690, etc.
The payer of support pays an ordinary medical addition to basic support eqal to the payer's percentage income share of the children's ordinary medical, per month.
For example, father nets $60,000 per year. Mother nets $40,000 per year. Father's percent of total income for the child is 60%. If Father pays support, he pays mother 60% of the child(ren)'s ordinary medical amount, per month, to Mother as an addition to basic support.
The person who receives support is then responsible for all ordinary medical expenses up to the ordinary medical amount. So, in our example, if Child goes to the doctor, and $150 of the bill is not covered, Mother must pay the entire bill, because it is less than the ordinary medical amount in the order. Many parents make the mistake of paying ordinary medical expenses by percentage of income. But, where one party pays the other support with ordinary medical, that party does not pay an ordinary medical bill until the other party has surpassed expenses covering the annual ordinary medical amount.
The recipient of support does not have to account for ordinary medical amounts. If the ordinary medical amount is not spent in any given year, the support recipient keeps the extra.
If the child(ren) incur(s) medical expenses beyond the ordinary medical amount, the parents pay these expenses based on their respective percentage of income. This is extraordinary medical. Extraordinary medical expenses are split by the parents by percentage of income.
If extraordinary medical can be anticipated in advance (think orthodontics or known medical expenses), these can be added as part of monthly support.
It is up to the person who receives support to claim extraordinary medical expenses, if there are any. The support recipient must document the expenses beyond the ordinary medical amount.
