"This is in a prior AV fistula that has developed stenosis just above the previously ligated fistula. Patient now has ischemic right hand pain with mild radial artery stenosis. Arteriotomy was made in the radial artery and endarterectomy was performed with removal of plaque from the primary area of stenosis and from the site of the previous arterial venous fistula. The remainder of the plaque was left intact as to not create and end point that would be difficult to manage, because the arterial wall was rather thin." Would you code this with 36832?
