Ask Dr. Z

Right arm fistula procedure. Normal access of the fistula and imaging (36147). There was a stenosis present in the innominate branch. Multiple attempts were made to cross this lesion from the inital access site. This was unsuccessful. The decision was made to obtain groin access and address the lesion from below. This attempt was successful. Now comes the question you've been waiting for... What on earth do I charge for the groin access and the venoplasty of the brachiocephalic? I did give a good ole college try...this is what I billed: 36147,36011, 35476 and 75978. i'm hoping that I wasn't too far off.
