Which coding combination is correct in reporting prolong add-on service code 99417?

• A. 99255, 99417
• B. 90838, 99417
• C. 99203, 99417
• D. 99245, 99417

Answer: (D)

Prolonged add-on code 99417 is for time beyond the usual amount spent on an office or other outpatient E/M encounter. It isn’t a stand-alone service and must attach to a true E/M visit in the office/outpatient setting, reflecting extra time spent with the patient. The best pairing here is an outpatient E/M visit that represents a comprehensive, high-complexity encounter, which aligns with the idea of spending substantial additional time. That makes 99245 the appropriate base code to pair with 99417. The other options fail because they either involve non-E/M services (psychotherapy), or an E/M code that isn’t the proper type or level to be extended with the prolonged-service add-on in this context (for example, a simple new-patient visit or a consultation code). So, reporting as 99245 with 99417 correctly reflects an extended, highly involved office/outpatient E/M encounter.
