Hi Guest!

D9243 - Intravenous moderate (conscious) sedation/analgesia – each 15 minute increment
can be crosscoded to:

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

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)


As for the diagnosis code(s), that will depend on the reason the patient was receiving the services. For example, if the tooth was knocked out from an accident, you may consider:

K08.412 - Partial loss of teeth due to trauma, class II
K08.413 - Partial loss of teeth due to trauma, class III
K08.414 - Partial loss of teeth due to trauma, class IV
K08.419 - Partial loss of teeth due to trauma, unspecified class

And then you would also choose a code to describe the accident, for example:
W01.0XXA - Fall on same level from slipping, tripping and stumbling without subsequent striking against object, initial encounter
W01.198A - Fall on same level from slipping, tripping and stumbling with subsequent striking against other object, initial encounter


If the implant was being placed for another reason, if you provide some additional details I can offer you some coding options.

Hope this helps!
