Final answer:
The correct CPT code for the described patient discharge scenario, which includes 45 minutes spent on various tasks, is 99239.
Step-by-step explanation:
The student is asking about the correct Current Procedural Terminology (CPT) code for a patient prepared for discharge with a total of 45 minutes spent on the final exam, instructions for continuing care, and arrangements made for home health. The appropriate CPT code for this scenario is 99238, which is used for hospital discharge day management services when the time spent by a physician is 30 minutes or less. Since the scenario mentions a total of 45 minutes, the correct CPT code would be 99239, which is used for the same service when the time spent is more than 30 minutes.
