Ask Dr. Z

Can do we code an ultrasound duplex venous with an AV fistulogram intervention? For the following example I'm thinking: 93971, 76937, and 36902. Is this correct?

"Ultrasound examination of the left upper extremity and intravenous fistula from the arterial anastomosis through the peripheral venous outflow demonstrated wide patency of the till anastomosis, juxta Esmarch segment, cannulation segment, and peripheral venous outflow. Prone images were saved. Using ultrasound guidance, needle was advanced antegrade into the cannulation segment. Sheath was used to perform outflow angiography through the central veins, which demonstrated multifocal stenosis within the cephalic arch. Angioplasty balloon was advanced, and prolonged balloon angioplasty of the cephalic arch was performed. Postplasty angiography demonstrated significant resolution of multifocal stenosis. Real-time concurrent ultrasound was used to visualize needle trajectory and a permanent image was stored in the medical record."
