I would assume that a catheter was taken out and used if one was ordered and charted. If a pt got a neb, it seems to follow that neb treatment should be charged. That seems easy enough to figure out and charge for.
My beef is that we end up double charting because EPIC doesn't drop charges when we chart. It's incredibly annoying. I have to chart the assessment; that should trigger a charge just like when I hang blood.
On top of that, we receive very spotty education on how to charge for infusions/injections (if your preceptor thinks to do it, you might get some training). Facilities that want to be paid the max should have people trained to capture those charges. Since they don't offer that training, they lose a ton of money. When it becomes a priority, they'll staff accordingly. Until then, they get what they get and if it's crazy busy, I'm a lot less careful and thoughtful in how I charge, because patient care and all that silliness.
