Dental Coding Reminder

Blue Cross Blue Shield of North Dakota (BCBSND) has identified a pattern of dentists billing Current Procedural Terminology (CPT©) code 21085 (Impression and custom preparation; oral surgical splint) incorrectly for Temporomandibular Joint (TMJ) Dysfunction splints. CPT© 21085 may only be used when the provider designs and prepares the prosthesis for creation of an oral surgical split. Dental providers are encouraged to submit claims using the Dental Procedure and Nomenclature (CDT©) code D7880 (Occlusal orthotic device, by report) when providing TMJ Dysfunction splits to BCBSND members.
