Our PCP offices add the Dx code for the routine procedure that the Provider is currently ordering for the patient. For example: Pt is here for her annual physical but she goes to ob/gyn for PAP. We add V76.2 to that DOS for the referral. Another example is a colonoscopy. We add V76.51 to the current DOS for the referral that will actually be performed in the future. Is this correct coding? If yes, why? If no, why? I think it is not because the service is not being performed on that DOS.
