Wiki dx for dialysis av fistula and/or graft

[conniff]

hope some of you coders out there can give me your opinions.
what is the proper way to dx an av fistula or an av graft that has stensosis.

I've been second guessing myself with:
996.73 comp due to renal dialysis device, implant, and graft
996.74 comp due to other vascular device, implant, and graft
996.1mech comp of other vasc device, implant , and graft

Correct - 996.73 comp due to renal dialysis device, implant, and graft.
