A colleague came across an ER visit that a CT scan WITHOUT contrast was ordered for a patient who recently had a kidney transplant due to right sided abdominal pain. Unfortunately, the patient was given contrast and was treated with IV fluids. There were no adverse reactions. The big question is, Would you use a poisoning code for the contrast? 977.8 And would you use E947.8 (contrast media) or E876.8 other specified misadventures during medical care? Yeah, I know, it's a toughie. Any help would be greatly appreciated!
