When coding IVP's for the ER, is it necessary to use the HCPCS book to identify the drug that was given, for example patient was given an IVP with Zofran at 10:30 pm? I did code the IVP as 90774. Also, if the patient was given Zofran at 10:30 pm and then again at 2:30 am, do I code it as 90774 x 2 or would I code it as 90774, 90775 or would I code it as 90774, 90776?
At first I thought 90774, 90775 but 90775 states each additional seqeuntial intravenous push of a new substance/drug, but since it is the same drug, Zofran, I am unsure if this is the correct code.
Now 90776 states each additonal sequential intravenous push of the same substance/drug provided in a facility (List seperately in addition to code for primary procedure), so being that the Zofran is the same drug that I coded in 90774, would I code the additional push as 90776? Now if the patient was given the IVP with Zofran at 3 different times, how would I code it, 90774, 90776 x 2?
Also, how would I code an IV that was started in the field and monitored in the ER, if I code it at all. For example, patient arrived at the ER via helicopter at 815 am (motorcycle accident) IV was started in the field, pt was given an IVP of Zofran at 10:15 am and another one at 2:15 pm. Before patient was discharged IV was noted to still be running. Do I code the IV and the IVP or just the IVP?
Thanks in advance
