Ask Dr. Z

How would I code the below scenario? Please help!! "Initially, we had trouble negotiating the right coronary artery into the fistula due to the 180-degree turn; however, once we were able to accomplish the AV loop, we were able to take the Neuro catheter all the way into the mid segment of the fistula. Once we had accomplished this, we removed the AV loop and then advanced the 9 mm microvascular plug. We then deployed the 9 mm microvascular plug successfully and performed an additional angiography conforming that the microvascular plug was in position prior to its release."
