Hi Guest! D9940 D9940 has been deleted from the coding system, replaced with the following 3 codes: D9944 occlusal guard – hard appliance, full arch D9945 occlusal guard – soft appliance, full arch D9946 occlusal guard – hard appliance, partial arch If this code is being use to bill medical insurance for appliances being used to treat temporomandibular joint disorders, most practices we work with will code that as D7880, which stands for: occlusal orthotic device, by report Since this code has “by report” in the description, they can explain in the narrative report what the appliance is/does. Now, you will every so often run into a medical insurer that will not process any code starting with a “D” – most do these days, but not all. In those cases, you end up using the closed CPT code that is “by report” or “miscellaneous”. The top options seem to be: 21299 – Unlisted craniofacial and maxillofacial procedure E1399 – Durable medical equipment, miscellaneous D2740 – crown – porcelain/ceramic substrate D2750 – crown – porcelain fused to high noble metal There are not a direct crosscodes we are aware of for these procedures, so you can either use the “D” code on the pre-authorization request/medical claim (many insurers these days will process “D” codes when they are medically necessary services), or you can use the CPT code below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures Hope this helps!
