Hi Guest!

D6245 - pontic - porcelain/ceramic
D6740 - retainer crown - porcelain/ceramic
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 use the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures

Hope this helps!
