My understanding is most carriers would want 00170 but other carrier want the D code to process, so would have watch for denials and how many units they allow for D9223 if they do want that code:
CPT 00170 Anesthesia for intraoral procedures, including biopsy; not otherwise specified
The typical primary diagnosis is:
K02.9
Dental caries, unspecified
It imperative to have access to the patient past medical history to list diagnoses why they need to be placed under general anesthesia versus being able to be done in a dentist office, For example, here would be common reasons general anesthesia would be needed for dental procedure:
F79
Unspecified intellectual disabilities
F84.0
Autistic disorder
F91.9
Conduct disorder, unspecified
E66.01
Morbid (severe) obesity due to excess calories
I50.9
Heart failure, unspecified
