Some nurse things can be bulk billed - there is a special code. It's been a while since I've had anything to do with billing so I can't recall all the things they can bulk bill for. My memory is a little hazy but if the nurse doesn't have a provider number, it is bulk billed on the Dr's provider number but as a certain nurse task code.

Hopefully one of the practice nurses on here (and there are a few) can shed some light on it for you including if what they did is legal. My feeling is that it is NOT legal as I vaugely recall reading a case about a Dr who did this and got prosecuted (successfully). BUT, I could be wrong. As I said, it's been a loooooong time since I've done billing.

If you're not comfortable with it, feel free to call the rooms as ask them to explain it. You can call Medicare and they may chose to investigate.
