Is it common practice to code D0120 with a restorative code as well? If so, must it be specifically stated in the clinical note that an exam was done? Can D0140 be used with restorative, extraction and palliative codes?
It is not common practice to code D0120 with treatment, this is used for 6 month check-up. You are to use D0140 or D0170 for exams with treatment as long as the documentation supports an exam at the same time.
