We need guidance on the below scenario. Our doctor evaluates patient at first visit, second visit the NP follows treatment plan with same dx (bills incident to), then a psychologist treats patient with a new dx, then the NP follows up with patient after psychologist and adds the new dx code given by the psychologist. Can the first doctor add an addendum onto the psychologist note stating that she has reviewed the treatment plan? Would that allow the NP to bill incident to with the new diagnosis that the psychologist has given because the first doctor reviewed and did an addendum to the doctor psychologist note? Or can the doctor do a separate note stating that she has reviewed the psychologist note and agrees/decides on the new dx code as a revised plan of treatment? Any advice would be helpful.

Thank you in advance.
