Provider sees a patient and bills the appropriate e/m code. This same patient is admitted within 30 days and when I look for documentation of the admit code(same doctor), I find the office visit note, only stamped with "no interval changes in physical condition" and signed by the provider. I am being told this is legal and appropriate to bill both using the same note. If indeed, this is true please cite a reference cuz it doesn't seem correct. Thanks.
