One of my students had a question that I could not answer. Maybe somebody out there knows the answer.

A general dentist specializing in Oral Appliance Therapy takes impressions of the teeth for these appliances and then sends the immpressions to an outside lab for fabrication. These claims use to go to dental, but with the changes this last year now go to medical since they move bone, tissue and muscle.

Do they bill them the same as when they were sending the claims to dental or do they have to add a modifier since they only take the impression but do not fabricate the appliance?

Thanks for any help.
