Hi Guest!

D6056 - prefabricated abutment - includes modification and placement
D6058 - abutment supported porcelain/ceramic crown
D6245 - pontic - porcelain/ceramic

There are not direct crosscodes for crowns and abutments, 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

There are no standard modifiers to use for this billing scenario.

Hope this helps!
