Neurology & Pain Management Coding Alert

Question: We've recently begun performing a test n our office that our neurologists are calling a "long exercise test." It's basically a repetitive stimulation test with multiple stimulations, and it takes over an hour to complete. I know that when we bill for it, we can only use the code once per nerve, but is there any way we can account for the extra time these tests take?
