3. No insurer may impose any requirements on a state agency, which has been assigned the rights of an individual eligible for medical assistance under chapter 208 and covered for health benefits from the insurer, that are different from requirements applicable to an agent or assignee of any other individual so covered.
4. All insurers shall in any case in which a child has health coverage through the insurer of a noncustodial parent:
(1) Provide such information to the custodial parent or legal guardian as may be necessary for the child to obtain benefits through such coverage;
(2) Permit the custodial parent or legal guardian, or provider, with the custodial parent's approval, to submit claims for covered services without the approval of the noncustodial parent; and
(3) Make payment on claims submitted in accordance with subdivision (2) of this subsection directly to the parent, the provider, or the MO HealthNet division.

However, claims for current or past due child support shall take priority over claims by the MO HealthNet division.
6. The remedies for the collection and enforcement of medical support established in this section are in addition to and not in substitution for other remedies provided by law and apply without regard to when the order was entered.
