Hi Guest! D7251 – Coronectomy – intentional partial tooth removal There is not a direct crosscode for coronectomy we are aware of, so typically you can either bill the “D” code on the medical claim (many insurers these days will process “D” codes when they are medically necessary services), or use the CPT code 41899 (Unlisted procedure, dentoalveolar structures) with a narrative description. If you use 41899, you can use the ZZ qualifier to provide a short description of what procedure the code is being used to represent. The JP qualifier to indicates the tooth numbers. So for example, if it was tooth number 1 & 16, it would read: JP1 18 The ZZ qualifier indicates you will be providing a short description, like this: ZZ coronectomy Hope this helps!
