I recently joined a family practice / Urgent Care who sends out all of our X-Ray films to an outside radiologist for a second opinion. For the initial X-Ray, we bill it normally, both technical and professional components. For the second opinion, we are billing it under the same physician number, the day after the service date, with a modifier 26. These are paid by most carriers, denied by some. My question is: Is this procedure correct? Thank you in advance.
