Hi, Medical insurance will not recognize or convert D0470 for diagnostic cast/study model prior to orthognathic surgery, even though their medical policy states that diagnostic cast/study models are medically necessary for this purpose, and they requested and received the casts/models to approve payment for the surgery. The cast was only for a study model for the surgery to correct mandibular hyperplasia. No splint was fabricated to put into the mouth. Can you help with a medical code for D0470? Thanks!
