The Illinois Department may provide by rule for certification to the Comptroller of amounts spent on child medical care. The purpose of the certification shall be to intercept, to the extent necessary to reimburse the Illinois Department for its costs, State income tax refunds and other payments due to any noncustodial parent who (i) is required by court or administrative order to provide insurance or other coverage of the cost of health care services for a child eligible for medical assistance under this Code and (ii) has received payment from a third party for the costs of those services but has not used the payments to reimburse either the other parent or the guardian of the child or the provider of the services.
The rule shall provide for notice to the person and an opportunity to be heard. A final administrative decision rendered by the Illinois Department under this Section may be reviewed only under the Administrative Review Law.
