Question: When our orthopedist admits a patient to the hospital after-hours from the emergency department (ED), which codes should I report? Arkansas Subscriber Answer: If the orthopedist performs the ED visit and admission on the same date, you should combine all services that the physician performs and documents into one admission code (99221-99223, Initial hospital care, per day ...). CPT considers all E/M services that a physician provides on the same date in another site of service part of the initial hospital care. So when your orthopedist performs same-day outpatient and inpatient services, you should include the ED work in the initial hospital care level. Watch out: Don't bill an ED visit and admission unless the orthopedist performs both services. If the ED physician treats the patient but the orthopedist performs the hospital admission, each physician should report his respective service.
