Except in cases of medical emergency or court-ordered admissions, a person shall be admitted to a state mental health institute for treatment of a substance-related disorder only after a preliminary intake and assessment by a department-licensed treatment facility or a hospital providing care or treatment for persons with substance-related disorders licensed under chapter 135B and accredited by the joint commission on the accreditation of health care organizations, the commission on accreditation of rehabilitation facilities, the American osteopathic association, or another recognized organization approved by the board, or by a designee of a department-licensed treatment facility or a hospital other than a state mental health institute, which confirms that the admission is appropriate to the person’s substance-related disorder service needs. A county board of supervisors may seek an admission of a patient to a state mental health institute who has not been confirmed for appropriate admission and the county shall be responsible for one hundred percent of the cost of treatment and services of the patient.
