Hi Guest! D7997 – appliance removal (not by dentist who placed appliance), includes removal of archbar The code listed above does not have a direct crosscode we are aware of, so 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 you can try one of the CPT codes below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures 40899 – Unlisted procedure, vestibule of mouth 41599 – Unlisted procedure, tongue, floor of mouth Hope this helps!
