True Blue
I can really use some help. I have physicians that are having someone draw blood and send it out to the various labs to process. The normal thing. But now I have docs that think that because you are sending it out to a lab, they want to use modifier -90. How do you use -90 properly. We send all blood out for processing. I never seen anyone try to use -90 modifier for it though. Any suggestions?
