Question: Oklahoma Subscriber Answer: Once you know the timeframe, you can choose the appropriate code. You'll probably report 99212 (Office or other outpatient visit for the evaluation and management of an established patient ...) or 99213 most often. Code 99212 typically represents 10 minutes of additional face-to-face time spent counseling with the patient; 99213 typically represents 15 minutes. Remember to append modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) to whatever E/M code you choose. You'll also report the age-appropriate code for preventive medicine services. For a new patient, choose from 99381- 99384 (Initial comprehensive preventive medicine evaluation and management of an individual including an age and gender appropriate history, examination, counseling/anticipatory guidance/risk factor reduction interventions, and the ordering of laboratory/diagnostic procedures, new patient ...). Established patient codes include 99391-99394 (Initial comprehensive preventive medicine evaluation and management of an individual including an age and gender appropriate history, examination, counseling/anticipatory guidance/risk factor reduction interventions, and the ordering of laboratory/diagnostic procedures, established patient ...).
