I am looking for a help on meds administration into two different IV SITES. For example:

IV SITE L AC established at 20:00– Benadryl IVPB 20:00-20:45
Zofran IVP 20:50 (coded as 96365 & 96375)

IV SITE R AC established at 20:05–Banana Bag IVPB 20:10–21:30 (coded as 96365)

Morphine IVP 20:10 (no IV SITE documented)
Reglan IVP 20:35 (no IV SITE documented)

Can Morphine and Reglan be coded as default to IV SITE L AC because the IV SITE L AC was established first at 20:00 or not coded because the IV SITES of administration were not specified?

thank you so much for help,
NIKI
