The department has developed a schedule of services that it will provide overall. When you look at the schedule's extensive list, you see that about 40% of the services require pre-approval. The department has predetermined that if a dentist prescribes or requires to give a patient a particular service, then 40% of those services would require pre-approval.
What the department has demonstrated is that in the claims they pay for, only 4% of the claims have actually come back, having received or required a pre-approval.
