If you have an urgent medical problem when the office is closed, the on-call physician or our nursing service is available to assist you. Our internal medicine and pediatric practices utilize an expert nursing service for late night and overnight coverage; a physician is also available for backup or for more complicated issues. The on-call physician is either your regular physician or one of the other physicians in the practice. If you feel you are having a medical emergency or feel you need to go to the emergency room, please proceed directly to the New York Presbyterian ER or your closest ER and you may inform us the next day. The ER staff will alert us at any time if they deem it necessary.
