The child's parent or guardian is liable to the Maryland Department of Health for all payments made on behalf of the child by this Program. The child's parent or guardian shall take any steps necessary to secure health benefits available for the child from a public or private benefit program. Upon notification to the provider that the child has insurance or other coverage for services covered by this chapter, the provider shall seek payment from that source. If payment is made to a provider by both the Program and other insurance or other source, the provider shall refund the Program, within 60 days of receipt, the amount paid by the Program or the insurance or other source, whichever is less. The provider shall reimburse the Program for any overpayments.
