(d) Nothing in this Act shall be construed to require any private professional practice, whether by an individual practitioner, by a partnership, or by a duly incorporated professional service corporation, that provides outpatient treatment for substance use disorders to be licensed under this Act, provided that the treatment is rendered personally by the professional in his own name and the professional is authorized by individual professional licensure or registration from the Department of Financial and Professional Regulation to provide substance use disorder treatment unsupervised. This exemption shall not apply to such private professional practice that provides or holds itself out, as defined in Section 1-10, as providing substance use disorder outpatient treatment. This exemption shall also not apply to licensable intervention services, research, or residential treatment services as defined in this Act or by rule. Notwithstanding any other provisions of this subsection to the contrary, persons licensed to practice medicine in all of its branches in Illinois shall not require licensure under this Act unless their private professional practice provides and holds itself out, as defined in Section 1-10, as providing substance use disorder outpatient treatment.
