(305 ILCS 5/10-23) Sec. 10-23. Employer obligations. If a parent is required by a court or administrative order for support to provide coverage for a child's health care expenses and if that coverage is available to the parent through an employer who does business in this State, the employer must do all of the following upon receipt of a copy of the order of support or order for withholding:

(1) The employer shall, upon the parent's request, permit the parent to include in that coverage a child who is otherwise eligible for that coverage, without regard to any enrollment season restrictions that might otherwise be applicable as to the time period within which the child may be added to that coverage.

(2) If the parent has health care coverage through the employer but fails to apply for coverage of the child, the employer shall include the child in the parent's coverage upon application by the child's other parent or the Illinois Department.

(3) The employer may not eliminate any child from the parent's health care coverage unless the employee is no longer employed by the employer and no longer covered under the employer's group health plan or unless the employer is provided with satisfactory written evidence of either of the following:

(A) The court or administrative order is no longer in effect.

(B) The child is or will be included in a comparable health care plan obtained by the parent under such order that is currently in effect or will take effect no later than the date the prior coverage is terminated. The employer may eliminate a child from a parent's health care coverage if the employer has eliminated dependent health care coverage for all of its employees.
