Iowa Code § 225.27
The state psychiatric hospital may, at any time, discharge any patient as recovered, as improved, or as not likely to be benefited by further treatment. If the patient being so discharged was involuntarily hospitalized, the hospital shall notify the committing judge or court of the discharge as required by section 229.14 or section 229.16, as applicable. Upon receiving the notification, the court shall issue an order confirming the patient's discharge from the hospital or from care and custody, as the case may be, and shall terminate the proceedings pursuant to which the order was issued. The court or judge shall, if necessary, appoint a person to accompany the discharged patient from the state psychiatric hospital to such place as the hospital or the court may designate, or authorize the hospital to appoint such attendant.
