Established clients are being referred to prescribers. Prescribers are billing New E/M vs Established. Why? Because this is their first encounter with client. Claims are denying because claims are being billed under same group. The insurance is basically saying client is established. Are these claims denying is error? I don't think they are. However, our higher ups seem to think claims are denying in error. Coding guidelines state that “A new patient is one who has not received any professional services from the physician or another physician of the exact same specialty and subspecialty who belongs to the same group practice, within the past three years.” HELP!!!!
