Dear Gail, I am not making any promises but try using two ICD.9 codes for dialysis access: 1. Renal dialysis V45.1 2. Renal dz, HTN, FMH, Thromb.etc 403.91 note: I believe that to use a code beginning with "V" that another code explaining the dz must be included?? I am sorry to be so vague but we are all flailing about out here with this medicare and coding nightmare. Let me know how it works out for you.
