To the extent funds are appropriated by the legislature for such purpose, in all adoption subsidy agreements executed after September 1, 2001, involving a child in the custody of the Department of Children and Family Services, the state shall agree to provide acutely medically necessary in-hospital mental health treatment for that child until he reaches the age of majority, provided that the child is not eligible for, or has otherwise exhausted benefits under Medicaid, LaCHIP, or any contract of health and accident insurance or any health benefit plan. The burden of providing the appropriate documentation of the child's eligibility for medical benefits under this statute shall be upon the adoptive parents.
