chemo without MD present?

In the clinic i work at our policy is that for certain treatments (which are most of them) a doctor is required to be present. some treatments like bisphosphonates, gemzar, navelbine, 5FU don't require a doctor to be present. Every new treatment requires a doctor and most of the other meds require a doctor due to the potential for an allergic reaction. The treatments that don't require a doctor require a PA or nurse practioner. We have to have a provider we never do any treatments (even epos, port draws) with only nurses present, not only safety issues but I believe medicare guide lines or billing rules or something.

IN our clinic we can't start and IV, access port, or draw blood until there is a doc in the building. I don't know if this is just our policy or a law.
