"Of note, the CPT description is interpreted as requiring an image of the target vessel, but not necessarily an image of the needle in the vessel as it is entering. It is believed that obtaining an image of the needle as it is entering the vessel poses unacceptable risks to the patient as it would require the solo operator to take his or her attention away from the procedure in order to obtain an image. It is recommended that permanent recording of the selected vessel or of the needle entering the vessel when this is feasible and safe, while using a procedure note to document the procedure was performed with concurrent real-time visualization. While a still image of the target vessel prior to successful cannulation is acceptable, a post-procedural still image of the catheter in the vessel, once the line is secure, is preferable."
