My auditor stated that the 90792 has to be coded down to the code range 99202-99205 if the documentation does not support 90792 because the patient is a new patient. Is this correct?90792 is not subject to the 3 year rule as for example the 99211-99215 are. The diagnostic interview exam is done when the provider first sees a patient, but may also be utilized again for a new episode of illness, or for re-admission as an inpatient due to underlying complications.
