We have a similar process to Kathy's. However, each department/Unit has their own Floor Stock Requisition Sheet. The items that are patient chargeable are on it as well as Non-chargeable items. The sheet is faxed to the Pharmacy and filled. Once a week, I enter the non-chargeable items into Cardinal's IDB system on Cardinal.com and it creates a bill I send to accounting at the end of the month to disburse.
Write ins are not allowed on FS sheets. If it is an item they don't stock that is needed, they have to have a doctors' order and the charge is generated when entered in the Pharmacy.
Our PYXIS talks to our computer system, so any items taken out are charged off to the patient.
