I do a ton of DME in my office, but I do it with ortho braces. The credentialing isn't really that hard except for with medicare patients and I only have a handful of those and I have worked out a deal with my suppliers that with medicare patients, I give them the braces, but get all their info, and get them to sign a form and my DME suppliers will bill for the medicare ones if i write a script and the brace is just replaced in my office no charge because technically i didn't use that brace, the DME company did.
Now with nebs and such, I would find out how much of a mark up there is between buying the machines and what gets covered and how often they get covered. If there is a 200 gap then that is a lot of money to leave on the table.
The other way you can do it is that if you are actually stocking the DME stuff in your office for the company, you are supposed to charge them a "space rental fee". What you are doing is called Consignment. So you shouldn't be letting them use space in your office and getting to bill everything while you go through the hassle of all the paperwork (time is money) and they get to collect. So part of that fee includes what it takes to do the work.
I would be happy to speak to you more on it with details of your set up.
