Final answer:
The appropriate CPT code for a Medicare patient's one-hour outpatient cardiologist consultation with comprehensive history, exam, and moderate medical decision making is 99244.
Step-by-step explanation:
The correct answer to the question is A) Office or Other Outpatient Consultation (99244). This CPT code is used for office or other outpatient consultations when the service provided includes a comprehensive history, a comprehensive examination, moderate complexity decision making, and the visit lasts typically 60 minutes face-to-face with the patient and/or family. In this case, the cardiologist provided a comprehensive history and examination for the new patient (NP), moderate medical decision making (MDM), and followed up with a written report to the primary care physician (PCP), indicating that code 99244 is the appropriate level of service.
