(a) In each Title IV-D case in which a medical support order requires that a child be enrolled in a health care program under Section 154.1826, the Title IV-D agency may administratively adjust the order as necessary on an annual basis to reflect changes in the amount of premium costs associated with the child's enrollment.
(b) The Title IV-D agency shall provide notice of the administrative adjustment to the obligor and the clerk of the court that rendered the order.
