Outpatient Chemo Charges

WE HAVE A SMALL OP UNIT WITH 4 BEDS AND 5 CHAIRS. BECAUSE OF A NEW COMPUTER SYSTEM OUR CHARGES HAVE BEEN REEVAULATED. WE CURRENTLY HAVE A SEPARATE CHARGE FOR IV PUSH CHEMO(5FU, ETC) AND ANOTHER FOR OTHER CHEMOS. IT SEEMS WE ARE NOT BEING COMPLETELY REIMBRUSED FROM SOME INSURANCE COMPANIES BECAUSE OF THE WAY WE CHARGE. I NEED TO KNOW HOW OTHER OP UNITS CHARGE. ALSO HOW DO YOU CHARGE FOR IVPB ZOFRAN, AND OTHER ANITEMETICS? WE ALSO HAVE A PROBLEM CHARGING FOR PORT FLUSHES. WE CAN CHARGE FOR THE ITEMS USED TO FLUSH BUT NOT FOR THE NURSES TIME DOING THEM. IF LABS ARE DRAWN WE DO CHARGE FOR THAT. SOME CHARGE FOR AN IV START, BUT WE WERE TOLD WE COULD NOT DO THIS. DOES ANYONE HAVE A CHARGE SPECIFICALLY FOR PORT FLUSHES DONE MONTHLY? AM A NEW USER AND REALLY ENJOY THIS SITE. THANKS FOR ANY HELP.
