Ask Dr. Z

If my provider performs a fistulogram and angioplasty in the peripheral segment (venous anastamosis), then also obtains femoral access due to 100% occlusion of the innominate vein and performs angioplasty, am I correct in assigning 36902 without modidifer -52, 36012, and 37248? And what about if he does a complete fistulogram via AVF and finds patient to have total occlusion of subclavian, gains access through femoral, and performs angioplasty of subclavian? In these instances are we okay to report catheter placement with intervention code via remote access as well as 36901 or 36902 without modifier -52?
