Except for the enumerated exceptions (focal dystonia, hemifacial spasm, orofacial dyskinesia, blepharospasm, severe writer's cramp, laryngeal spasm, dysphonia), the record must state that traditional methods of treatment have been tried and proven unsuccessful.

Focal dystonia, hemifacial spasm, orofacial dyskinesia, blepharospasm, severe writer's cramp, laryngeal spasm, and dysphonia are recognized indications for which prior failure of traditional therapies is not required to document medical necessity.
