Hi Guest!

D6010 - surgical placement of implant body: endosteal implant
can be cross coded to:
21248 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); partial (3 or less)


D6104 - bone graft at time of implant placement
Can be cross coded to:
21215 - Graft, bone; mandible (includes obtaining graft)
**use modifier -52 for reduced services when bone is not obtained from patient


D9222 – deep sedation/general anesthesia – first 15 minutes
and
D9223 – deep sedation/general anesthesia – each additional 15 minutes
can be crosscoded to:
00170 - Anesthesia for intraoral procedures, including biopsy; not otherwise specified

D9999 - unspecified adjunctive procedure, by report (Exparel Injection)
can be crosscoded to:
S0020 - Injection, bupivacaine hydrochloride, 30 ml


D9610 - therapeutic parenteral drug, single administration
can be cross coded to:
96374 - Therapeutic, prophylactic, or diagnostic injection (specify substance or drug); intravenous push, single or initial substance/drug


D4266 - guided tissue regeneration - resorbable barrier, per site
D7240 - Removal of impacted tooth - completely bony

As for guided tissue regeneration & extractions, they do not have direct crosscodes 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 codes below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures


Hope this helps!
