JOAN RIVERS’ daughter has filed a malpractice claim against the New York medical clinic that treated her mother days before she died.

    Rivers suffered a cardiac arrest while undergoing a procedure to examine her throat at the Yorkville Endoscopy center in August 2014.

    The legal claim alleges doctors were not adequately trained and performed unauthorized procedures on the star.

    Rivers’ family is seeking unspecified compensatory and punitive damages.

    In November, state health investigators said the clinic failed to follow standard protocols while treating Rivers, who died a week later.

    The Department of Health cited multiple errors, including failing to detect the comedian’s deteriorating vital signs during the procedure, but negligence was not suspected.

    The New York medical examiner’s office ruled Rivers died of brain damage due to lack of oxygen during the procedure.

    The death was classified as a “therapeutic complication,” meaning it was a known risk.

    However Melissa Rivers claims doctors mishandled the endoscopy and performed another procedure — carried out by specialist Gwen Korovin who was not cleared to work at the clinic — without consent.
