N.M. Admin. Code § 8.50.109.15
The support order should include a set amount and specify that the amount is designated for cash medical support as outlined in Section 40-4C-3 NMSA 1978. This amount should be in addition to and not in lieu of the non-custodial parent's obligation to pay a percentage of unreimbursed medical expenses. Either the custodial party or the non-custodial parent may request the court to order the provision of cash medical support. The IV-D agency will enforce a provision for cash medical support established or modified by any party so long as the support order designates a specific dollar amount to be paid in regular, equal installments (i.e., monthly, bi-weekly, weekly). If the order does not designate a specific dollar amount for medical support purposes, the IV-D agency is not required to collect the money.
