According to TMZ, Korovin isn’t authorized to practice medicine at the Yorkville Endoscopy center, where Rivers went Aug. 28 to undergo a scheduled endoscopy by gastroenterologist and the clinic’s medical director Dr. Lawrence Cohen. After that procedure, CNN reports Rivers also underwent an unauthorized vocal cord biopsy performed by her personal doctor.

Korovin’s office said in a statement, “We do not comment on matters related to patients.”

On Sept. 5, the New York Medical Examiner’s Office told TheWrap that the autopsy on Rivers’ body did not determine the cause or manner of death, and that further studies would be conducted to determine exactly how she died.
