Ask Dr. Z

An AVF angioplasty and embolization was performed and provider queried because stenosis percentage was missing for intervention. The provider responded that the stenosis was greater than 50% but angioplasty was performed for low flow volume due to failure of maturation and treated with assisted maturation (angioplasty) to increase the diameter of the AV fistula to allow for access in dialysis and adequate flow volumes to achieve dialysis. The patient also underwent coil embolization to redirect outflow of the fistula at the same time to increase flow volumes in the distribution of access in the cephalic vein. When angioplasty is performed for this reason, is stenosis percentage still required in the documentation?
