Hi I am trying to figure out this whole DOTD/CDL Physical. Currently we are using a 99214 with a diagnosis of Z02.89. Our doctor is certified to give DOTD/CDL physicals; we are unsure about whether or not we are to bill the insurance for this or if we can say we don't bill for this and them pay the fee upfront. Any information on this would be VERY much appreciated! We are a small new practice.
