NEW YORK - New York University's Langone Medical Center plans to reopen its doctors' offices and out-patient procedure and testing sites on Monday but its emergency department remains closed after the hospital lost power due to Hurricane Sandy. 

The hospital, which was forced to evacuate its patients on Monday night, said on Sunday that it had no update yet on when it would be able to start taking in over-night patients again or when its emergency department would be back up and running.

In a statement issued Friday night, the hospital said that patients with previously scheduled appointments should call 866-724-1830 to confirm the location of their appointments.

The Hospital for Joint Diseases is still open and The Center for Muscuskelatal Care and the Clinical Cancer Center will also reopen on Monday November 5, according to the hospital.

However it advised patients of the Clinical Cancer Center and the Stephen D. Hassenfeld Children's Center for Cancer and Blood Disorders who want to reach their doctor to call 800-400-8566 in the interim.

The Langone Medical Center evacuated its 215 patients, including critically ill infants, and closed its doors on Monday night after its back-up power generator failed because of flooding its basement.
