Revision of leg bypass by ligation of the fistula in the bypass

Date: Apr 2, 2019

Question:

Patient has swelling in the leg and has a leg bypass. Found to have three fistulae in the fem distal bypass. Fistulae were not thrombosed. The procedure: "Incision was made in the proximal thigh, and the fistula was dissected out and ligated with a clip. This was done in the same fashion to the two other fistulae." I'm not sure how to code this. It seems they are revising the bypass graft and not an AV fistula. Should I reported unlisted code 37799? Code 35903 doesn't seem correct because there is no infection. I'm undecided if 37607 would be correct. 35883 but there is no aneurysm. Do you have any suggestions?
