Pt brought to cath lab and sheath was inserted in L femoral artery...Following this, cath was advanced in AA, and an Abdominal aortogram was performed. Following this, cath was pulled back into distal aorta, above iliac bifurcation. Bilateral iliac arteriograms w/bilateral femoral runoffs were performed. Then decision was made to perform PTA and stenting of R. SFA. I think codes would be 75630-59 for bilateral runoffs, 37226 for PTA/stent and 36247? Is this correct? I am just learning this or trying to so I sometimes think I overthink this....Help!
