Enforcement of orders for health care.

A. All Title IV-D agency cases shall include a provision for the health care coverage of each child. In the case in which a medical support obligor parent provides such coverage and changes employment and the new employer provides such coverage, the state Title IV-D agency shall transfer notice of the provision to the employer, which notice shall operate to enroll each child in the medical support obligor's health plan unless the medical support obligor successfully contests the notice. B. For purposes of this section, "medical support obligor" means a person owing a duty to provide health support, or against whom a proceeding for the enforcement of such a duty of support is commenced or for registration of a support order that includes provisions for such support for each minor child.
