I found an answer
After much searching and plodding through Medicaids billing instructions I found the answer to my question and thought I would share it since no one else seemed to know.
In the Physician Services section of the billing instructions, there is a section that states:
One pre-operative E&M procedure by a physician for a dental client prior to performing dental surgery in an outpatient setting. You must bill using dental diagnosis codes 520.1–525.9 as the primary diagnosis when billing E&M codes for pre-op services for dental surgery, along with the appropriate pre op diagnosis codes V72.81–V72.84) as the secondary diagnosis.
