S.C. Code § 44-52-160
If a person who was involuntarily committed violates the conditions of his release including a failure to adhere to an outpatient treatment program as ordered by the court, the court may, upon a written affidavit of the head of the treatment facility or the director of a treatment program under whose supervision the person was released, and upon notice to the person and his counsel, order a supplemental hearing and further order inpatient treatment. The probate court issuing the order shall maintain jurisdiction over the person for the purpose of supplemental proceedings.
If a person who violates the conditions of his release is in such a condition that he poses a substantial risk of physical harm to himself or others, the court may, upon a written affidavit of the head of the treatment facility or the director of a treatment program under whose supervision the person was released, order the patient to be returned to the treatment facility from which he was released pending the conduct of a supplemental hearing which must be held within seventy-two hours from the time of admission to the facility.
Any person with respect to whom further involuntary inpatient treatment is ordered as a result of the supplemental hearing, may be recommitted for a period of treatment not to exceed sixty days.
