Pt had chr.kidney dz stage IV (585.4), Doc did creation R.Brach-Ceph AVF (36821) and Exp/thrombectomy R.Ceph Vein. I don't think 36831 (thrombectomy,open AVF w/o revision) is right. Am I? Because doc created the R.Brach-Ceph AVF at same time. do you think 37799 would be the answer? (I tried to see between 34401-34490, and cannot see one) Can anybody help me find the right code if 37799 is wrong.
Thank you
