And a spokesman for the New York Police Department said: "An 81 year old is in a critical condition at Mount Sinai Hospital."
He was unable to confirm reports on the TMZ website and CNN that Rivers' heart had stopped beating at one point.
US news sites reported that she was undergoing a throat procedure in a clinic when she became unwell, but the spokesman could not confirm this.
He said the emergency call was made at 9.39am local time from an address in East 93rd Street, Yorkville, where there is an outpatient centre which describes its mission as to "serve as a community resource for digestive disorders".
