305 ILCS 5/5-2.2
A parent or other person having custody of the child or a spouse who fails or refuses to comply with the requirements of Title XIX of the federal Social Security Act, and the regulations duly promulgated thereunder, regarding establishment and enforcement of the child or spousal support obligation shall be ineligible for medical assistance and shall remain ineligible for medical assistance for as long as the failure or refusal persists.
In addition to any other definition of failure or refusal to comply with the requirements of Title XIX of the federal Social Security Act, in the case of failure to attend court hearings, the parent or other person can show cooperation by attending a court hearing or, if a court hearing cannot be scheduled within 30 days following the court hearing that was missed, by signing a statement that the parent or other person is now willing to cooperate in the child support enforcement process and will appear at any later scheduled court date. The parent or other person can show cooperation by signing such a statement only once. If failure to attend the court hearing or other failure to cooperate results in the case being dismissed, such a statement may be signed after 2 months.
No denial or termination of medical assistance pursuant to this Section shall commence during pregnancy of the parent or other person having custody of the child or for 30 days after the termination of such pregnancy. The termination of medical assistance may commence thereafter if the Illinois Department determines that the failure or refusal to comply with this Section persists. Postponement of denial or termination of medical assistance during pregnancy under this paragraph shall be effective only to the extent it does not conflict with federal law or regulation.
