"Melissa does plan to sue the clinic," a source close to Melissa Rivers told the Mail. "She is going to launch a lawsuit."
After her death, it was reported that Dr. Gwen Korovin, the ear, nose and throat specialist who accompanied Rivers to the clinic but was not authorized to practice there, performed an unplanned biopsy after noticing something on Rivers' vocal cords during the procedure. Prior to the surgery, Rivers had consented to an endoscopy, but not a biopsy. Yorkville Endoscopy has denied that a biopsy was performed on Rivers, and the clinic's medical director has stepped down in the wake of Rivers' death.
Korovin, who also reportedly took a selfie in the room, is currently still accepting new patients, according to the Daily Mail. Her other celebrity clientele includes Lady Gaga, Hugh Jackman and Celine Dion. Korovin's lawyer, citing confidentiality laws, has declined to address reports of her alleged involvement in Rivers' death.
Rivers' death is under investigation by the New York Department of Health and the city's medical examiner.
