Our physicians offer a walk-in flu clinic that is open to the public. A flu injection is given to a person that is not a patient of record. A record is created at the time of the injection. A couple of weeks later the patient presents with a sore throat. Should the sore throat visit be coded as an new patient or established patient visit? I understand an E & M is a face to face visit with the physician. The injection was not face to face but the adminstration code was billed to the insurance company with his name on the claim. I am looking for documentation to support the correct answer.
