Anesthesia Coding Alert

Test your coding knowledge. Determine how you would code this situation before looking at the box below for the answer. Question: I know that Medicare allows billing for anesthesia service if a physician cancels a case after induction (using modifier -53, Discontinued procedure). Would this also apply to a monitored anesthesia care (MAC) case when the anesthesia provider administers IV medications for sedation and anesthesia prior to cancellation? If not, how should I bill for the time spent on an unsuccessful attempt at closed reduction? The patient returned later the same day for general anesthesia and a successful reduction.
