The patient and representatives shall have the rights specified in those notices. Hearings held pursuant to this subsection shall be held as provided in Code Section 37-7-81.1, and the court holding the hearing may issue any order authorized by and subject to the limitations of that Code Section 37-7-81.1.

(b) If the patient is notified of the hearing as required under subsection (a) of this Code section and does not appear at or waive that hearing, absent a showing of good cause for not appearing, the court may issue an order commanding any peace officer to take such person into custody and deliver that person to an emergency receiving facility or the referring facility if there is a physician or psychologist available there, and this chapter shall thereafter apply to that patient as though the patient had been admitted to that facility pursuant to subsection (b) of Code Section 37-7-41.

(c) If the hearing is waived as provided in subsection (a) of this Code section, that hearing shall not be held but the court shall order the patient to obtain available outpatient treatment under the individualized treatment plan submitted with the petition for hearing.
