In my experience, if the hydration is part of the treatment regimen and specifically in the order to be given pre and/or post drug infusion, it is billable. We have one medication - I believe it's Cisplatin - that causes significant kidney toxicity when given so hydration is always part of the regimen. Pre & post drug infusion for a defined period of time. We don't have issues getting paid for it. If hydration is given strictly to keep the IV open regardless of other meds given, it's not billable. Check how the regimen is written and, as stated by the other posters, why the hydration is ordered. What is your company's policy regarding hydration administration? I did a quick search and didn't see anything indication hydration was recommended or required with Rocephin administration so I would look for some other reason, such as nausea, vomiting, dehydration, diarrhea, etc for the hydration.
