This CPB is revised to state that an orthopantogram is medically necessary for evaluating persons for oral appliances for obstructive sleep apnea. This CPB is revised to state that X-rays of the temporomandibular joint and sella turcica have no proven value for evaluating persons with obstructive sleep apnea. This CPB is revised to allow custom-made and prefabricated oral appliances as first-line therapy for obstructive sleep apnea.
