The Department shall make all rules and regulations and take such action as may be necessary or desirable for carrying out the provisions of this Code, to the end that its spirit and purpose may be achieved and the public aid programs administered efficiently throughout the State. However, the rules and regulations shall not provide that payment for services rendered to a specific recipient by (i) a person licensed under the Medical Practice Act of 1987, whether under a general or limited license, (ii) a person licensed or registered under other laws of this State to provide dental, optometric, or pediatric care, or (iii) a licensed clinical social worker may be authorized only when services are recommended for that recipient by a person licensed to practice medicine in all its branches.
Whenever a rule of the Department requires that an applicant or recipient verify information submitted to the Department, the rule, in order to make the public fully aware of what information is required for verification, shall specify the acceptable means of verification or shall list examples of acceptable means of verification.
The provisions of the Illinois Administrative Procedure Act are hereby expressly adopted and incorporated herein, and shall apply to all administrative rules and procedures of the Illinois Department under this Act, except that Section 5-35 of the Illinois Administrative Procedure Act relating to procedures for rule-making does not apply to the adoption of any rule required by federal law in connection with which the Illinois Department is precluded by law from exercising any discretion, and the requirements of the Administrative Procedure Act with respect to contested cases are not applicable to (1) hearings involving eligibility of applicants or recipients of public aid or (2) support hearings involving responsible relatives.
