Hi Guest! Great question. Dental coding & billing is not our forte here like medical coding & billing is! On the medical side, the surgical guide is often considered included in the reimbursement for the implant when it is a covered expense, but if billed separately: D6190 – radiographic/surgical implant index, by report This code 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 use the CPT code below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures
