No hospital would be able to run by being restrictive with flushes. You just need to use so many of them for IV management and drug administration alone, not to mention all the other stuff we use them for. Essentially every time you put something into an IV line, you need to flush it to get the medication to the patient and you need to periodically flush it to keep it patent. I will document them for Inputs/Outputs with someone who has a heart/kidney problem, but that's as far as it goes. Billing wise, it's subsumed under how they bill for "nursing" as an average, so it's not tracked for that either.
