Hi guest! D7270 – tooth reimplantation and/or stabilization of accidentally evulsed or displaced tooth D2331 – resin-based composite – two surfaces, anterior D2950 – core buildup, including any pins when required D2740 – crown – porcelain/ceramic substrate None of the codes listed above 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 the CPT code below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures Hope this helps, have a great day!
