Question: California Subscriber Answer: The chief factor in determining whether a patient is new or established is always time. You must de-cide whether your physician has seen the patient in the past, and if he has, how long ago. These guidelines also apply to a new urologist in an established practice such as in this case. How it works: If the new urologist has provided face-to-face professional services to a patient elsewhere, such as in a hospital or other practice, within the last 36 months, the patient is an established patient even if this is his first visit to your practice. Rule: If your physician has seen the patient for a professional service in the past three years, you'll report any subsequent visits with established patient E/M codes (such as 99211-99215). Remember: Professional services that do not involve a face-to-face encounter, such as interpreting an x-ray or reviewing laboratory tests without seeing the patient, do not count toward this rule. The services involved must include a face-to-face service and encounter.
