You should know their demographics and be comfortable with them because these patients will become your patients. You should always answer that you have no problems seeing anyone who needs you. Always stay on point with this, because you just can't go wrong. Many groups and hospitals have a 'life-and-limb' list of doctors rotating turns and seeing unassigned emergency patients. If a hospital accepts Medicare or Medicaid funds, then no patient can be refused in their Emergency Department. Even if your private practice doesn't accept these patients, you will still be required to see such patients as part of doing your duty on a 'life-and-limb' ED rotation and, as part of that, you must also provide follow-up, regardless of your office practice preferences. Of course, with your specialty, it is assumed you accept Medicare.
