Hi Tameka! D4266 – guided tissue regeneration – resorbable barrier, per site can be cross coded to: 41870 – Periodontal mucosal grafting D6010 – surgical placement of implant body: endosteal implant can be cross coded to: 21248 – Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); partial(3or less) 21249 – Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); complete (4 or more) D6058 – abutment supported porcelain/ceramic crown D2740 – crown – porcelain/ceramic substrate D6057 – custom fabricated abutment – includes placement The codes listed above do not have direct crosscodes 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 Hope this helps!
