D9239 - Intravenous moderate (conscious) sedation/anesthesia – first 15 minutes

99152
Moderate sedation services provided by the same physician or other qualified health care professional performing the diagnostic or therapeutic service that the sedation supports, requiring the presence of an independent trained observer to assist in the monitoring of the patient’s level of consciousness and physiological status; initial 15 minutes of intraservice time, patient age 5 years or older

and

99153
Moderate sedation services provided by the same physician or other qualified health care professional performing the diagnostic or therapeutic service that the sedation supports, requiring the presence of an independent trained observer to assist in the monitoring of the patient’s level of consciousness and physiological status; each additional 15 minutes intraservice time (list separately in addition to code for primary service)


D4265 - biologic materials to aid in soft and osseous tissue regeneration

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


Hope this helps!
