An unnamed Yorkville Endoscopy Clinic staffer also told the news organization that the doctor — described as Joan's personal ear-nose-throat physician — reportedly took a selfie while Rivers was under anesthesia.

Rivers was at the clinic for a scheduled throat procedure by another doctor, gastroenterologist Dr. Lawrence Cohen. When he was finished, the comedian's personal doctor (whose name has not been released) reportedly began to perform a biopsy without her prior consent, according to CNN. The ENT was not certified to perform procedures at the Manhattan clinic, as required by law, says CNN.
