(a) Each individualized service plan for available outpatient treatment shall be reviewed at regular intervals to determine the patient's progress toward the stated goals and objectives of the plan and to determine whether the plan should be modified because of the patient's present condition. These reviews should be based upon relevant progress notes in the patient's clinical record and upon other related information; and input from the patient should be obtained and utilized where feasible.

(b) Any time a patient is found by the physician or psychologist in charge of the patient's outpatient treatment no longer to be a mentally ill person requiring involuntary treatment, that physician or psychologist shall discharge the patient from further compliance with the treatment.

(c) Notice of the discharge under subsection (b) of this Code section shall be given to the patient and his representatives; to the court which originally ordered such involuntary treatment; and, if the patient was under criminal charges of which the facility received written notification, by certified mail or statutory overnight delivery to the law enforcement agency originally having custody of the patient.
