Hi Guest!

D4268 - surgical revision procedure, per tooth
In Aetna's policy titled "Oral Surgery Dental in Nature", the CPT crosscode for D4268 is:
41874 - Alveoloplasty, each quadrant (specify)


D6245 - pontic - porcelain/ceramic
D6740 - retainer crown - porcelain/ceramic
D2950 - core buildup, including any pins when required

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!
