I have an op report in which the physician was going to perform a AV fistula repair for poorly functioning fistula. Physician felt that the stenosis could be bypasssed, but found that the vein was heavily scarred and the fistula could not be salvaged, he therefore, closed the wound and attention was turned to the basilic vein in the forearm. Being that there were two separate incisions, in which I am billing for, my question what modifier would be appropriate? I code for a ASC. Looking at modifier 74, but uncertain ?

Thank you
