Joan Rivers Cause of Death Update: Comedian's NYC Medical Clinic Loses Federal Accreditation

Yorkville Endoscopy, the Manhattan clinic that provided the late Joan Rivers with an upper-gastric endoscopy and a laryngoscopy that ended up costing her her life, is set to lose its federal accreditation at the end of January,

ABC News reports following the death of Rivers, the New York State Department of Health investigated the clinic and cited it for a number of deficiencies, including failure to properly monitor Joan's vital signs.

The Centers for Medicare & Medicaid Services (CMS) later stepped in with their own investigation on the clinic and recently came to its decision that Yorkville Endoscopy will no longer be eligible to receive federal funds for services provided to Medicare and Medicaid beneficiaries, The Associated Press reports.

This decision will naturally be a big blow to the company; however, ABC News reports that the clinic is looking to appeal CMS' decision.

Rivers died on Sept. 4 following her visit to York Endoscopy on Aug 28. She was admitted to the hospital following the clinic's procedure on the late comedian's vocal chords. Rivers later died in the hospital from cardiac arrest brought on by complications that occurred during the procedure.

Among the complications and signs of negligence reported during Rivers' procedure was one report of a Yorkville Endoscopy staff member allegedly taking pictures of Rivers on her phone while the comedian was under anesthesia

Last month, the details of Rivers' will were released. The court documents show that Rivers was worth $150 million and named her daughter and two additional undisclosed people as the executors of her estate.

In addition to being named executor, Rivers' daughter Melissa was reportedly given all of her mother's tangible property, including her $35 million Upper East Side apartment and house in Connecticut.

Rivers was also sure to include money for various charities in her will, including God's Love We Deliver, California's Guide Dogs for the Blind, the Jewish Guild for the Blind in Manhattan, the Jewish Home and Hospital Federation of Manhattan, the Simon Wiesenthal Center and The Cystic Fibrosis Foundation.

Rivers died at the age of 81.
