Hi guest!

D6740 - retainer crown - porcelain/ceramic
D6245 - pontic - porcelain/ceramic
D3310 - endodontic therapy, anterior tooth (excluding final restoration)
D2954 - prefabricated post and core in addition to crown
D7140 - extraction, erupted tooth or exposed root (elevation and/or forceps removal)

The codes listed above do 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 the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures

Hope this helps, have a great day!
