(1) The director shall adopt and may amend and repeal rules for acceptance of persons into the substance use disorder treatment program, considering available treatment resources and facilities, for the purpose of early and effective treatment of persons with substance use disorders and persons under the influence of drugs. In establishing the rules, the following standards must guide the director:
(a) If possible a patient shall be treated on a voluntary rather than an involuntary basis.
(b) A patient shall be initially assigned or transferred to outpatient treatment, unless or until he or she is found to require residential treatment.
(c) A person may not be denied treatment solely because he or she has withdrawn from treatment against medical advice on a prior occasion or because he or she has relapsed after earlier treatment.
(d) An individualized treatment plan shall be prepared and maintained on a current basis for each patient.
(e) Provision shall be made for a continuum of coordinated treatment services, so that a person who leaves a facility or leaves a form of treatment will have available and utilize other appropriate treatment.
