A: When you call the doctor on call, many situations can be handled without an emergency room visit. You will be called back by the physician on call. HHWNY does not take part in a call pool, so the doctor calling you back is from HHWNY. If the physician feels that you or your loved one needs to be seen, arrangements can be made for an after hours visit at HHWNY or sometimes even a home visit. However, if the physician feels your situation requires more urgent care, you will be directed to an emergency room.
