Would appreciate any input for the following which was performed to assess a non functioning saphenofemoral AV fistula. The femoral artery was puntcured and a sheath placed, femoral arteriogram was done which showed SFA was cacified but the anastomosis was patent, fistula was patent but there was an area of tight stenosis just beyond the loop of the fistula.
Is the correct code 36147 or 36140 and 75791???
