Wiki Is it appropriate to bill for sodium chloride

[RadVCCoder]

We are a group of radiologist who own and operate an Imaging Center in MN. We are currently billing for sodium chloride however we are receiving a ton of denials and some of our claims wont even go through the clearing house. I have narrowed the issue down to the sodium chloride we bill out when we do pain injections and CT or MRI's. I am wondering if it is even appropriate for us to be billing these? I have done tons of research online but I am not able to find a source that clearly states if it is appropriate or inappropriate.
I am looking for any feedback on what other imaging centers do and if it is appropriate or inappropriate.
