Has anyone encountered this procedure as a means to "revise" an AVF. There’s not a lot of information out there and I’m not finding any references to how it should be coded (I’m thinking Unlisted).

From what I can tell, it’s a way to revise the fistula that is less invasive with a combination of a small incision and a catheter/balloon. So, it’s not as involved as 36832 or 37607 (fewer, smaller incisions).

If you’re coding this, are you using Unlisted code 37799?

Thanks
